Question: Why should you choose a Smardt oil-free chiller?

Answer: They provide the highest efficiencies and lowest cost of ownership, whilst also increasing reliability by eliminating conventional chiller issues.

Conventional Chiller Issues

• Inefficiency – particularly at part load• Inability to run continuously at part loads• Noise and Vibration• Unreliability and High Maintenance• Electrical constraints• Physical constraints - size, weight and cost of replacements• Cost of Maintenance, Parts, Filters, and Oil• Oil Related Problems

– Oil Return Issues– Reductions in Heat Transfer– Contaminated Waste Disposal

Conventional Chiller Issues – One Source

• Compressor Technology is the major source of chiller issues and affects a chillers ability to;– reduce energy consumption– Accurately match operating conditions– Offer more environmentally friendly solutions– Reduce operating costs over a chillers lifetime

• Today’s dominant ‘solution’:– Combine old compressor technologies, such as screw

compressors, with variable speed technologies to reduce energy consumption.

– This may improves efficiency, but accentuates oil-related issues

Conventional Centrifugal Chiller – Oil Issues• Gears - Friction

– Gears used to increase the impeller speed, resulting in friction and lubrication requirements

• Oil Sump is needed– Typically 15 gallon of compressor oil required and yearly oil

change is recommended

• Emergency oil reservoir– Provides protection during power loss to the oil pump

• Oil cooler is required – Removes the heat generated from the sleeve bearing friction

• Oil filter required– filter the oil before going to the bearing.

• Oil heater is required– Heats up the oil when chiller is not in operation to prevent oil

foaming when the compressor starts up– Heater consumes energy even when chiller in standby mode

• Oil Differential pressure switch critical– is the safety device to protect the compressor.

The Effects of Oil

• The top ASHRAE study determined the average quantity of oil as a percentage in older chillers. The average is 12.88%.

• The bottom study equated presence of oil to efficiency loss.3.5% of oil = 8% efficiency loss.

• Smardt Chillers have been designed around the oil-free Turbocor compressor and as such do not use any oil.

The effect of prolonged oil in the system

- A healthy approach of 1C

- Accumulation of oil increase the approach to 3C

- Additional 2C will reduce efficiency by approx. 20% (based on 5C ∆T)

The Effects of Oil

Ever increasing price of oil and its by-products

• Price of petroleum by-products linked to crude oil• Annual increase of 15% on the price of oil• For a chiller plant room with 3 x 500RT, estimated annual oil consumption

*USD10,000

(*assume each chiller required 15 gal and oil price @ USD200/gal)

The Direct Cost of Oil

The In-Direct Cost of Oil

Diagram: as this comparative study showed, over 20% of lubricated chiller's operating efficiency is routinely lost in the early years as a result of oil clogging of heat transfer surfaces.

Conventional Screw Chiller Piping

Piping is very complex when you need to account for the presence of oil, and guarantee proper oil-return.More Complexity =Increased Failures

Piping becomes very simple when you no longer need to account for the presence of oil, and the typical need for oil-return.

Smardt Oil-Free Chiller Piping

The Smardt-er Alternative - One Solution

• A Magnetic Bearing, Oil-Free, Centrifugal Compressor.• Designed from the “ground up” to address the issues

and the need for environmental responsibility.• This revolutionary compressor provides:

– Increased Energy Efficiency– Elimination of Oil Related Issues– Noise Reductions– Reduced Maintenance Requirements– Weight and space reductions– Increased Chiller Capabilities

PermanentMagnet, DC Motor

Motor & BearingController

• Magnetic Bearings– Eliminate high mechanical

friction losses– Increase equipment

life through elimination of wear surfaces

– Eliminate oil-related heat transfer losses

– Eliminate complex oil management systems (controls and hardware)

Key Technologies - Magnetic Bearings

• Active re-centering of the shaft at 100,000/second.• Movements measured and actively adjusted in mere microns.• Shaft kept controlled and centered to within 7micron.

(1/10th of the diameter of a human hair.)• Back up bearings are included to prevent damage to the shaft

should a control or bearing failure occur.

Magnetic Bearing System

Power Outage?

• Within 0.5 of a micro-second, the motor becomes a generator, feeding power to the various controls and bearing actuators during a controlled coast-down.

• The onboard capacitors have enough power to fully support the bearing system during the switch from motor to generator mode.

• After the compressor comes to a complete stop, the rotor de-levitates normally onto touchdown bearings.

• Smardt Chillers can be rapidly restarted without concern as there is almost no inrush current to the motor and there are no oil based constraints.

Variable Speed Drive

• The Compressors speed adjusts automatically to match the load and current operating conditions so that optimum efficiency is gained.

• We vary the speed for most of our capacity control, and only use the Inlet Guide Vanes when beyond the range of solely relying on speed.

• The slower the compressors, the greater the efficiency. As speeds is reduced, energy consumption is reduced by the cube.

– Speed Energy3

• Speed range of 12,000 – 45,000 r.p.m.

• This oil-free compressor has essentially only a single moving part• The compressor’s high speed capability, reduces its overall size• Centrifugals offer the highest aerodynamic compression efficiency at full load

and with an integrated VSD, they also provide the best part load efficiencies

Simplest Centrifugal Compressor

> Multiple Compressor Capacity Models:

– 60-170TonR / 200-600kWR

> All Compressor Models are the same physical size:

– Dimensions(cm): 90 x 60 x 75

> Extremely light weight, – Less than 140kg

• An innovative, permanent magnet, brushless DC motor which helps to reduce the size of the compressor:

• The motor is 160hp but is the size of a conventional 1hp induction motor.

• Compare the motors in the picture:– Rear = Turbocor 160HP motor– Front = conventional 120HP motor

Smallest Centrifugal Compressor

— Conventional Start— Typical Soft Start— Smardt Soft Start

Smardt-Chiller – True Soft Start

Diagram: Smardt chillers, require only 2 amps for start-up, compared with 1200-1400 amps in conventional machines.

• Low in rush current, ideal for replacement and retrofit projects - 1:1 ratio generator sizing

Further savings for owners, who can reduce maximum power loads and reduce backup generator size.

Smardt RestartHow Smardt Restart works The advanced Smardt controls see the power failure and switch to a

fast restart mode, which alters the chiller’s compressors start logic. On the compressors the fast-start function will skip the IGV and

bearing calibration. Once the power is restored, the shaft will levitate and the motor will

ramp up at approx. 1000 rpm per second to satisfy the cooling load

Fast-start benefits Chiller back on line within 20seconds. Fluctuation in chilled water loop temperature

limited Applications where chilled water supply is

critical will not be impacted by a intermittent power loss

Flexible start up times Eliminate additional thermal storage

Protection All power losses are logged and recorded. The start-up mode has additional motor and surge

protection

• No pre/post lube required (conventional oil-lubricated compressors takes around 60 seconds to do pre/post lube)

• No oil heater; smaller UPS required• No oil temperature checks required• No mechanical stress on compressors during restart• No thermal stress on motor during multiple restarts• No IGV calibration required• No power surge on restart – 2 Amps starting current• No coast down cycle • No hours based limitation on number of restarts

(open drive compressors should only be restarted twice an hour)

• Controller remains powered up and communicating• Fast chilled water recovery with Smardt’s proprietary

programme• Eliminate the need for additional thermal storage
