INTRODUCTION

This is the twentieth monthly status report prepared by AiResearchManufacturing Company of California under Contract NAS8-32091 for the NationalAeronautics and Space Adminstration Marshall Space Flight Center (MSFC). Thereport summarizes activities from July I to July 31, 1978.

For simplicity in reporting, activities are reported by subject matter

rather than by WBS item number.

MEETINGS, REVIEWS AND MAJOR ACTIVITIES

Activities during June were as follows

" A meeting was held in Albuquerque, N.M., with Bridgers and Paxton,consulting engineers for the Novato, Ca., SHAC site on July 7, 1978.Bridgers and Paxton were informed of changes in site concepts sincethe site was reactivated. Mssrs. Benson, Yee and Walker of AiResearchprovided latest site equipment infonaton

* A qjarterly review meeting was held at AiResearch on July I1,1978 toassess program progress. Program acceleration methods were reviewedin detail with Mr. James Clark of NASA/MSFC. Mssrs. P. Benson, R. Nelson,R. Susag and H. Yee of AiResearch attended.

* A contractor/owner interface meeting was held at Portland, Ore., on July 12, 1978 with the Bonneville Power Authority (BPA) to discuss details onthe contemplated Redmond SHAC site. Mssrs. J. Clark and R. Gunner ofNASA/MSFC and Benson, Yea and Walker of AiResearch attended this meetingand the meeting at Novato the following day. AaResearch is to provide asystem schematic, and ISPI and an updated drawing of the 25-ton unit toBPA personnel. The meeting amounted to a design concept presentation byBPA with a critique by AiResearch rather than the usual preliminary designreview.

" A contractor/owner interface meeting was held July 13, 1978 at Oakland, Ca.regarding the Novato site. Site-related cost estimates were made and meansof consolidating NAVY and NASA funding explored to cover house modifications.

* A contractor/owner interface meeting (Houston Job Meeting No. 20) was heldat Houston on July 20, 1978, with Mssrs. Clark and Gunner of NASA and Mr.Benson of AiResearch attending. Cost of repairing the storage tank damagedin transit to Houston inJune were directed to AiResearch.

Meetings scheduled for the month of August include.

* An overall program status and site status meeting at Dunham-Bush, Inc. onAugust 2 and 3, 1978.

* A contractor/owner interface meeting at Lawrenceburg, Tenn., on August 17, 1978.

* A contractor/owner interface meeting at Redmond, Ore., on August 23, 1978.

SYSTEM DEVELOPMENT

The activities reported below involve heat pump component design, fabricationand testing, and heat pump package development.

Component Design, Fabrication and Test

I. Turbomachines

(a) 3-Ton Unit

Unit D-2 was bench tested prior to installation in the heat pump package(which had been transferred from Dunham-Bush to AiResearch). It exhibited nounusual characteristics. Upon installation, rubbing occurred and the unit wouldnot start. It was concluded that a torque caused by turbine inlet duct loadingwas causing deformation. The duct was realigned and tests were continued in thecooling mode without incident for two days to check system operation. On thethird day, rubbing occurred during start and the unit was removed for examination.Seal rubbing was apparent at both the turbine and compressor-end seals. Furtherinvestigation revealed that several of the journal bearing undersprings were softand could cause rubbing due to instability. Two other units were checked (onethat exhibited intermittent rubbing and one that had not). The unit which had rubbedhad soft springs, the other did not. All undersprings were replaced with stiffersprings. As a secondary precaution, the Dunham-Bush heat pump was reworked toeliminate the possibility of duct misaJignment.

Testing was then resume with the freon pump in operation. The pump failed and itwas found that the wrong power was being applied (208V instead of liOV). Upondisassembly, it was found to be contaminated with carbon particles. The turbomachinewas removed and the compressor also evidenced carbon deposits. The reversing valvewas determined to be the problem and is being replaced with a steel unit using chromeplating as opposed to a carbon unit.

The system has been flushed clean with freon and is currently being reassembled.

Two additional units are available for shipment.

(b) 25-Ton Unit

Unit No. 1 is at Dunham-Bush. Unit No. 2 will be ready for shipment onSeptember 1, 1978.

(c) 75-Ton Unit

Unit No. I is at Dunham-Bush. System testing is to begin the first week ofAugust.

Unit No. 2 is complete and will be shipped to Dunham-Bush on August 4, 1978.

2. Motor Controller

(a) 3-Ton Controller

Tests are being conducted on the heat pump package at AiResearch.

(b) 25-Ton Controller

Controller No. 1 has been shipped to Dunham-Bush while Controller No. 2 is 60 percent complete.

(c) 75-Ton Controller

Controller No. 2 will be ready for shipment on August 15, 1978.

3. System Controller

Five controllers are completed and await shipment to Dunham-Bush when needed.

4. R-ll Liquid Pump

(a) 3-Ton Unit

Three pump units were delivered in March. Testing is now at the subsystemlevel.

(b) 25-Ton Unit

One pimp has been tested and shipped to Dunham-Bush. Assembly of the othertwo pumps is being held in abeyance pending system test evaluation.

Heat Pump Design, Fabrication and Test (Dunham-Bush Activity)

1. Camponents (at Dunham-Bush)

(a) 3-Ton Heat Pump

All components for four 3 -ton units are in house except for one condenser and

the turbocompressors, freon pumps and controllers listed in Chart 5 (Appendix A). Twoadditional reversing valves have been ordered to replace the ones with carbon spools.

(b) 25-Ton Heat Pump

All components are in house for one heat pump except for reversing valve andall for the second heat pump except the boiler/evaporator, reversing valve and

the imminent Chart 5 components.

(c) 75-Ton Heat Pump

All conponents are in house except those noted in Chart 5.

2. Assembly of Units (at Dunham-Bush)

One 75-ton unit has been assembled and is currently piped into the testfacility. Assembly is proceeding on the second 75-ton unit.

The first 25-ton heat pump has been removed fromr the test facility. It iscomplete except for the 4-way reversing valve which Is past due.

One 3-ton heat pump has been coipleted. The second and third units are nearing

completion and the fourth is about one-fourth assembled.

3. Tests of 3-Ton Heat Pump

The 3-ton heat pump was shipped to AiResearch the last week in June and alltesting this month has been done in Torrance Calif. All heat pimp testing atAiResearch was concentrated on the turbomachine rubbing problems. Consequentlyheat pump testing is reviewed in Section I (a) of this report.

SYSTEM DEVELOPMENT

The activities reported below involve heat pump component design, fabricationand testing, and heat pump package development.

Component Design, Fabrication and Test (at AiResearch)

1. Turbomachines

(a) 3-Ton Unit

After flush cleaning and reassembly of the heat pump system (after failureof the carbon reversing valveTesting was then delayed by failure of a commutator sensor. After part replace­ment, the unit experienced mode "hitting" problems at high speed. Subsequentexamination attributed the rotating assembly hitting to excessive sway space. Theturbomachine unit was being rebuilt with stiffer bearing support spacers toreduce the sway space at month end.

(b) 25-Ton Unit

Testing of the 25-ton unit is at the subsystem level at Dunham-Bush. (Referto the heat pump test section below).

c) 75-Ton Unit

Testing of the 75-ton turbomachine is at the subsystem level at Dunham-Bush.(Refer to the heat pump test section below.)

2. Motor Controller

(a) 3-Ton Controller

Tests are being conducted on the heat pump package at AiResearch.

(b) 25-Ton Controller

Controller No. I is at Dunham-Bush awaiting completion of the dual heat pumptest setup. The fabricatior of Controller No. 2 is now complete and thetesting of this controller has commenced.

c) 75-Ton Controller

Controller No. I is being tested with the heat pump package at Dunham-Bush.The checkout of Controller No. 2 is awaiting availability of a motor.

3. System Controller

Five controllers have been completed and checked out. Fabrication o thefinal three system controllers has started.

AIRESEARCH MANUFACTURtING COMPANY 76-13110(21)L~J OFCALIFORNIAB­

4. R-11 Liquid Pum2

(a) 3-Ton Unit

Three pump units were delivered in March. Testing is now at the subsystemlevel.

(b) 25-Ton Unit

One pump has been tested and shipped to Dunham-Bush. Assembly of the othertwo pumps is being held in abeyance pending system test evaluation.

Heat Pump Desiqn, Fabrication and Test (Dunham-Bush Activity)

1. Assembly of Units (at Dunham-Bush)

(a) 3-Ton Heat Pump

Two of the four 3-ton heat pumps have been revised to include changes similar to the 75-ton heat pump changes noted below. Revision is in process on the thirdheat pump and the fourth will be changed when it is returned from AiResearch.

(b) 25-Ton Heat Pump

The first 25-ton heat pump has been modified to incorporate changes similarto those made on the 75 -ton unit. The second is approximately 50 percent assembled.

(c) 75-Ton Heat Pump

In accordance with the request from Mr. Jim Clark, all piping interfaces havebeen brought to the edge of the heat pump and equipped with flanges.

To facilitate the flow of RIl to the refrigerant pump, the liquid outlet fromthe condenser was changed from the side to the bottom. A vortex eliminator wasplaced in the outlet and a direct connection was made to the refrigerant pump.The first unit is again ready for operation as soon as the compressor is receivedfrom AiResearch.

The second 75-ton heat pump is about 75 percent completed.

2. Test Activities (at Dunham-Bush)

The 75-ton heat pump operated for two days. On the third day, the turbo­compressor speed would not stay at 12j000 rpm and on each successive start,it stalled sooner untii, on the fourth attempt, itwould not start.

The compressor was disassembled and a badly burned thrust bearing was found. The grooves feeding refrigerant to the thrust bearing were too small. Thesegrooves were milled out to 9 times the original area and the compressor was thenreassembled with new thrust bearings. The same alteration was made on the second75-ton machine.

Both machines were bench-tested to adjust the commutator position sensor.Turbocompressor No. I was to be installed in the heat pump, but itwas out ofbalance, probably as a result of adjusting the sensors. The turbine wheel scrapedon the housing and this turbocompressor was shipped back to AiResearch.

The sensors-on turbocompressor No. 2 were adjusted and the turbocompressorseemed to operate satisfactorily. It was installed in the heat pump and the unitwas charged with 800 pounds of Ri. The turbocompressor was started and acceleratedto 12,000 rpm. It ran for about one minute, and suddenly decelerated as if heavilyloaded and the power was turned off. Power was reapplied for short periods severaltimes, but the unit would not start. The turbocompressor was removed and shippedback to AiResearch.

SITE ACTIVITIES

Status of Sites

1. Lawrenceburq, Tenn. (OTS No. 13)

- A SHAC.to~site inteFf-ce wiring diagram(AiResearch Drawing H-TENN-EI) was hand delivered to Jim Clark at Houston on September 7, 1978. In addition, various specification and clean, test and fill procedures regarding this site have been transmitted to the site director this month. (Refer to PROGRAM DOCUMENTATION section.)

2. Allaire State Park, N.J. (OTS No. 1])

Site activities are "on hold" pending discussions in October between thesite owner and Mueller Associates, Inc., regarding bid package changes toreduce the overall cost.

3. Harrisonburg, Va. (OtS No. 14)

Progress at this site remains essentially unchanged since last month. Thesolar collector system is complete and all the plumbing is done up to theheat pump connections. Only some small feeder air ducts and registers awaitfinal installation. SDAS instrumentation was received from IBM/Huntsvilleexcept for a current transformer and two probes. Installation will begin whenheat pump is received.

4. Novato, Ca. (OTS No. 14)

The technical specifications and drawinqs were received from Bridgersand Paxton Consulting Engineers, Inc. the A and E firm for this site, onSeptember 11, 1978. AiResearch is currently reviewing this package, alongwith Novato-PWC engineers and NASA personnel.

5. Redmond, Ore. (OTS No. 17)

Two BPA-Charles T. Main - AiResearch interface meetings were held. Duringthe first, technical data was submitted to BPA concerning direct-heat heatexchanger and the cooling tower design points, water circuit flow data andinsulation data.

C-2 76-13110(22)AIRESEARCH MANUFACTURING COMPANY OF CAIFORNIA

7. Houston, Texas (OTS No. 18)

Contractor interface difficulties have hampered progress at this sitecompounded by instrumentation changes in the Site Data Acquisition System.As a result of the September 7-8 meeting at Clear Lake City, Texas, andsubsequent related telecons, it appears that NASA considers AiResearch'sprovision of direct heat exchanger specific procurement information asImproper acceptance by AiResearch of the design responsibility of thisheat exchanger. Consequently, transfer of information between AiResearchand the University of Houston has been suspended, with all informationtransfer channels being routed through NASA. Final AiResearch commentson the Houston site AIP are being held pending written instructions fromNASA on correct submittal procedures. The September 28 meeting atTimmerman Engineers Inc., Houston was held to orient the local controlsfirm (Barber-Colman) of the heat pump mode selection automatic procedures.

8. Las Vegas, Nevada (OTS No. 19)

Direct-heat heat exchanger,design point data was released to NASA forthis site and the Houston site on September 14 and 15, 1978, in separate

letters. Dissemination of this data to the proper site authorities isrequested of NASA.

SYSTEM DEVELOPMENT

The activities reported below involve heat pump component design, fabricationand testing, and heat pump package development.

Component Design, Fabrication and Test (at AiResearch)

I. Turbomachines

(a) 3-Ton Unit

System testing at AiResearch with the Dunham-Bush heat pump package wascompleted. The unit was operated in the motor-driven mode successfully but couldnot be operated in the turbine-driven mode with freon change levels up to andincluding 155 lbs. This was attributed to piping problems within the package.Changes had been initiated at Dunham-Bush to correct this. Other system changesat Dunham-Bush were not incorporated in this unit, so testing was ended and the heatpump package was returned to Dunham-Bush for rework. All subsequent testingwill be at Dunham-Bush.

76-13110(22)AIRESEARCH MANuFACTURING COMPANY

OFCALIFORNIA C-4

During the testing at AiResearch, itwas concluded that duct alignment to thecompressor is very critical. It is anticipated that flex ducting will be requiredwithin the package to eliminate distortion.

(b) 25-Ton Unit

No testing has been acomplished during the past month. One unit is atDunham-Bush for system testing.

(c) 75-Ton Unit

One unit with increased thrust bearing cooling potential has been shippedto Dunham-Bush and is being installed in their system. Testing should begin thefirst week of October.

I. Assembly of Units (at Dunham-Bush)

(a) 3-Ton Heat Pump

I Two of the four 3-ton heat pumps have been revised to include the latest develop­ment changes. Revision is in process on the third heat pump and the fourth will bechanged when it is returned from AiResearch.

(b) 25-Ton Heat Pump

I The first 25-ton heat pump has been modified to incorporate latest development

changes. The second is approximately 60 percent assembled.

(c) 75-Ton Heat Pump

The first 75-ton unit is complete and presently in system testing with a modifiedturbocompressor.

The second 75-ton heat pump is about 75 percent complete and wait-ing receipt of theturbocompressor for the remaining plumbing.

2. Test Activities (at Dunham-Bush)

(a) 3-Ton Heat Pump

Systems testing with the latest plumbing changes has started with the major effort

directed toward operation in the turbine-driven cooling mode. Testing will continueinto October.

(b) 25-Ton Heat Pump

The 25-ton package is complete and installed in the test system. The system is onvacuum and testing will start the first week in October.

(c) 75-Ton Heat Pump

A turbocompressor with improved bearing cooling passages was installed in the testsystem. Motor-driven operation indicated that the controller current range is limited,which will require evaluation by AiResearch Engineering. Photographs of specific waveforms have been transmitted. Operation of the R-ll pump is now satisfactory due to therecent plumbing changes. The turbocompressor thrust bearing appears to be running warmethan anticipated and a modification is in process on the second unit to provide addedlocalized cooling flow.

OBJECTIVE

This paper presents a brief description of the solar­powered Rankine cycle heat pump and an outline of the latest six-ionth progress of the AiResearch Hanu­facturing Company of California, Solar Heating and Cooling Project, on NASA Contract Number NAS-32091.

SUMMIARY

During this period, subsystem level development was dominant, with problem solving both at the component and subsystem level providing the program emphasis The progress was highlighted by completion of the following milestones

I Rankine cycle cooling achieved with 3-tonsubsystem

2 75-ton subsystem (to be Installed at the University of Houston) operated in electric cooling mode

Progress has been at a pace slower than desired, due to design changes found necessary in system develop- ment However, no problems of any appreciable technical magnitude have been confronted The program is technically healthy, and proceeding toward a successful conclusion

BACKGROUND

The AIResearch system features a solar powered vapor-cycle heat pump using R-l as the workingfluid The heat pump turbomachine consists of aturbine, a compressor and a permanent magnet motor mounted on the same shaft The rotor is supported on process fluid bearings, no lubricants other than the process fluid are required The motor Is powered In the electrical mode from utility power through a solid-state converter generating variable highfrequency, thus providing variable speed operation

Solar energy Is collected using flat-plate copper

collectors and the thermal energy is transported by a water-ethylene glycol fluid flowing In a closed loop The heat energy is exchanged through an Inter­cooler to a water loop which transports the energy to an insulated storage tank Temperature in thistank can vary from 40 F to 210aF depending only onthe differences in energy every collection endenergy usage

The system Is presently being constructed in threesizes, 3-ton cooling (110,00 Btu/hr heating), 25-toncooling (800,000 Btu/hr heating) and 75-ton cooling (2,003,000 Btu/hr heating). The

25 -ton system Is

best used as the descriptive baseline since this

syste alone utilizes all of the modes heating and cooling Differences In the operational modes ofthe 3-ton and the 75-ton are explained later

Heating Operation

In the heating mode, two methods of energy transport are utilized Direct heating Is utilized wheneverthe storage tank temperature Is sufficiently higherthan the temperature required to passively conductheat to the conventional hydronlc thermal transportloop This loop carries the heat energy to the airhandlers in the various zones of the building Theheat transfer Is accomplished through a direct heatexchanger between the storage tank output loop andthe hydronic transport loop.

Whenever the temperature in the storage tank is in. sufficient to accomplishing the full heating require­ments of the building in the direct heating mode, the syston is automatically switched to heat pump operation In this mode, electrical energy Is supplied to the motor on the turboconpressor shaft to cause heat energy to be actively elevated in temperature so that the heat energy may pass from the lower temperature in the storage tank to the higher temperature hydronic transport loop The electrical energy provided to the motor in this mode is controlled to a value just sufficient to accomplish the heat energy transmission required by the build-

Ing As the temperature of the storage tank decreases,

the heat pump becomes Incapable of supplying allthe heat required and a control signal isprovidedto activate a conventional water boiler which then supplies only the difference Inthe heat required and the heat available from the heat pump Should the storage tank water tdmperature approach the

-MVNfreezing point, the heat Pump is automatically stopped, and all of the building heating require­ments are supplied by the water boiler

In the heat pump mode of operation, the R-11 working fluid isevaporated at a low pressure In the sub-M system Input heat exchanger called the boiler/ araporetor. Heat is extracted from the water In the thermal storage tank by the evaporation process, and the higher energy fluid Is compressed by the con­pressor and condensed In the output heat exchanger named the evaporator/condenser The higher pressure condensing process provides a heat source at asufficient temperature level for the building heattransport loop The liquid R-I1 Isconducted backto the expansion valve, thus closing the vaporcycle loop.

dooling Operation

In the cooling mode of operation, the R-1I working fluid isused simultaneously In two operationally separate vapor cycle loops, although these loops are actually physically combined through the use of a common condenser. In the Rankine cycle drive loop, thermal energy Is transported from the storage tank to the Input heat exchanger (boiler) where It Is used to vaporize the Working fluid at high pressure (about 85 psla) The high pressure (high energy) vapor isexpanded in the turbine to provide shaft power for the centrifugal compressor of the refrig­eratlon loop The expanded vapor from the turbine Is liquifled In the commnon condensor, and pumped back to the expansion valve at the boiler Inlet, thus closing the Rankine power loop In the refrigeration loop, the R-Il Is vaporized in the output heat exchanger (evaporator) at a low pressure, thus pro-viding cooling by lowering the temperature of thehydronic heat transport loop which supplies the various air handlers located In the building Thelow pressure vapor fron the evaporator Is compressed end combined with the turbine outflow before enter-Ing the condenser, where the vapor Is condensed through energy extraction by a water tower transport Ioop. Liquid R-l Is returned to the evaporatorthrough en expansion valve

Whenever sufficient energy Isavailable In the storage tank (as depicted by the storage tank water temperature), the Rankine power loop is capable of supplying all of the shaft power required to drive the compressor, and the electric motor requires no power other than that required to initially startthe turboconipressor The speed of the turbocompressor varies naturally dependent upon the operating conditions If the stored solar energy Is insufficientto maintain a minimum compressor speed, electric power is automatically supplied to the motor to augment the turbine power. If no thermal energy Is available to the turbine, the Rankine loop Is functionally terminated and the entire requirementsof the refrigeration loop are supplied by the electric motor drive subsystem.

Figure 2. Cooling Operation

Hinor variations In the-preceeding description exist In the 3-ton and the 75-ton systems. The 3-ton (single family, one zone) system utilizes an output heat exchanger (evaporator/condenser) In which building air Iscooled or heated directly, negating the requirement for a hydronic transport loop Design studies have Indicated that a passive energy transfer from the storage tank directly to the unit output air Is Impractical, and consequently no direct heating mode exists In the 3-ton unit Conversely, the 75-ton system does hot employ a heat pump heating mode due to the environmental nature of the two test sites selected for this system Both the Las Vegas and Houston areas do not require the heat pump heating mode since the heating requirements are most satisfactorily supplied by the direct heat-Ing mode

TECHNICAL ACCOMPLISHMENTS

During the past six months, significant progress hasbeen mad., both in the component and subsystemdevelopment areas. The following is a brief synopsisof the highlights of the development program

Turbocompressors

1.Compressor performances have been confirmed (3-ton and 25-ton)

2. The process fluid bearings have been optimizedin all three sizes of machines

3 The motor/motor controller Interface has beenperfected to a high degree of confidence

4 A single-center rotating section was designedto replace the multiple piece rotating section to reduce (3-ton) unit rotor runoutproblems.

5.Maximum speeds have been reached withoutIncident on all machines

6 Motor end bearing coolant circuits have beenImproved on all three sizes of machines
