AIR CONDITIONER, COMPACT, HORIZONTAL, 0003-00 THEORY OF OPERATION WITH OPERATON LOGIC (SEQUENCE OF OPERATION) TECHNICAL PRINCIPALS OF OPERATION Refrigeration Cycle – Cooling (Refer to Refrigerant Schematic, PG 0003-00-3) The refrigeration system removes heat from a given area. The refrigeration cycle is as follows: 1. The compressor (1) takes cold, low pressure refrigerant gas and compresses it to a high temperature, high pressure

gas. The gas flows through the copper tubing to the condenser coil (3). 2. The condenser fan draws outside ambient air over and through the condenser coil (3). The high temperature, high

pressure gas from the compressor (1) is cooled by the flow of air and is changed into a high pressure liquid. 3. The sight glass moisture indicator (7) indicates the presence of moisture and quantity of refrigerant in the system. 4. The filter-drier (6) removes any moisture (water vapor) or dirt that may be carried by the liquid refrigerant. 5. The expansion valve (4) senses the temperature and pressure of the refrigerant as it leaves the evaporator coil. By

use of the remote bulb and “external equalizer line” the valve constantly adjusts the flow of liquid refrigerant to the evaporator coil (2).

6. As the high pressure liquid refrigerant leaves the expansion valve (4) and refrigerant distributor (5), it enters the

evaporator coil (2) and “flashes” to a gas. This is due to the low pressure created in the evaporator by the compressor (1). The evaporator blower circulates the warm air, from the conditioned space, over and through the evaporator coil (2). Liquid refrigerant absorbs heat as it changes from a liquid to a gas. As the air flow from the conditioned space comes in contact with the evaporator coil (2) the air is cooled. If the air is cooled below its “dew point” moisture will condense on the evaporator coil (2) and be carried to the condensate drain. Thus providing both cooling and dehumidification.

7. The low pressure refrigerant gas is then drawn back to the compressor (1) and the cycle is repeated. 8. The hot gas by-pass valve (11) is used to maintain a minimum evaporator temperature by allowing some hot

discharge gas to flow to the evaporator coil (2) through the refrigerant distributor (5) when the evaporator pressure is low. This prevents freeze-up (ice formation) of the evaporator coil under low ambient temperature operation.

Heating When the MODE SELECTOR switch is set for HEAT, three (3) heating elements located behind the evaporator coil are energized. These elements are protected from overheating by a thermal cutout switch. The two (2) stage heating capacity is provided by switching the electrical connections of the three (3) heating elements. This is automatic by the control circuit. Compressor Starting Sequence (Refer to Wiring Schematic WP 0003-00-4) To limit the starting current (in rush) of the air conditioning unit an electronic sequencer (SS) is utilized to prevent any two (2) motors starting at the same time. This is applicable to the cooling cycle as follows: 1. On call for “cooling” by the control thermostat the sequencer (SS) opens the control circuit to the evaporator fan

motor (B2) contactor (K2) shutting off the evaporator motor (B2). 2. The sequencer (SS) then energizes the control circuit to the compressor contactor (K1) turning “ON” the compressor

motor (B1). 3. After 5 seconds the sequencer (SS) energizes the evaporator fan motor (B2) contactor (K2) turning “ON” the

evaporator motor (B2).

AIR CONDITIONER, COMPACT, HORIZONTAL, 0003-00 THEORY OF OPERATION WITH OPERATION LOGIC (SEQUENCE OF OPERATION) - Continued OPERATION LOGIC (SEQUENCE OF OPERATION) Operation The operation of the unit is controlled by a Navy-supplied remote control panel. This remote control panel consists of a thermostat and mode selector switch which interfaces with connector “J8” on the environmental control panel. The mode selector switch offers five modes of operation – cool, vent, off, lo heat and hi heat. The mode selector switch (and thermostat) switches 28VDC+ (pin A-J8) to the other various pins on J8 in accordance with the desired mode of operation. Input Power 208 volt, 3-phase, 400 Hz power is connected to environmental control panel through J1. The power is monitored for proper frequency by the FM (frequency monitor) relay. In the event of incorrect frequency, the normally closed (NC) contacts (2-1) open preventing power through the circuit breaker (CB5) to the control transformer (TR) primary and compressor crankcase heater (CH) thus preventing operation of the unit. The power is also monitored for proper voltage, voltage unbalance between phases, proper phasing, and phase loss by the phase monitor (PM). In the event of incorrect phase or voltage, the normally open (NO) contacts (4-5) remain open preventing control power (28 VDC+) to connector J8 and the evaporator and compressor start sequencer (SS), thus preventing operation of the unit. Circuit Protection (Over-current) The motor circuit are protected by circuit breaker CB1 (compressor motor B1), CB2 (evaporator fan motor B2) and CB3 (condenser fan motor B3). The electric heater (HR1, HR2 and HR3) circuit is protected by circuit breaker CB4. The control transformer primary (5-2) and the compressor crankcase heater (CH) are protected by CB5. The control transformer secondary (7-8) NS protected by CB6. The circuit breaker opens the electrical circuit in the event of over-current. Thermal Protection The motors are protected by thermal switches embedded in the motor windings S1 for the evaporator motor (B2), S2 for the compressor motor (B1) and S3 for the condenser motor (B3). The electric heater elements (HR1, HR2, and HR3) are protected from overheating by switch S6 which senses the air temperature at the heater. The switches open the 28VDC electrical circuits in the event of over temperature. Pressure Protection (High or Low Refrigerant Pressure) The refrigerant system is protected by pressure switches S4 low pressure and S5 high pressure. The low pressure switch functions to prevent the compressor operation with low or no pressure due to loss of refrigerant, etc. The high pressure switch functions to prevent compressor operation with high refrigerant pressure due to blocked condenser airflow, etc. Switch Circuit (S1, S2, S3, S4 and S5) The switches are circuited such that they only disable the mode of operation in which they are directly protecting. Switches S2, S3, S4 and S5 control the units function in only the “cool” mode, thus leaving the “vent” and “heat” modes operational. Switch S1 (evaporator motor), being necessary for operation in any mode, disable the total control circuit. Operation By Mode Selector Switch “Vent Mode” – with or without the remote panel thermostat satisfied. J8 pin “A” (28VDC+) is electrically connected J8 pin “C” by the mode selector switch. 28VDC+ power from rectifier RR flows through fan switch (NC) of evaporator and compressor motor start sequence (SS). Then to the evaporator motor contactor K2 coil terminal +A1 through coil out terminal –A2 to resistor R to contactor terminal 14 then to J2/P2 – P3/J3 pin “E”. Continuing to terminal board (TB)

AIR CONDITIONER, COMPACT, HORIZONTAL, 0003-00 THEORY OF OPERATION WITH OPERATION LOGIC (SEQUENCE OF OPERATION) - Continued OPERATION LOGIC (SEQUENCE OF OPERATION) - Continued terminal 8 through the evaporator motor (B2) thermal protector S1 and back through TB-7 and through J3/B3 – P2/J2 pin “C” to the -28VDC terminal of the rectifier RR. Thus energizing contactor K2 which supplies the 208 volt, 3-phase, 400Hz power to the evaporator motor B2. Cool Mode Without remote panel thermostat satisfied J8 pin “A” (28VDC+) electrically connected to J8 pin “B” and “C” by the mode selector switch. 28VDC+ power from rectifier RR flow to the evaporator motor (vent) circuit as above and also to “Y” of the evaporator and compressor motor start sequencer SS starting a one minute delay sequence. After one (1) minute the fan switch within the SS sequencer opens the circuit to contactor K2 shutting down the evaporator motor and completes the 28VDC+ circuit within the sequencer SS to the “Y-out” terminal. Then to contactor K1 coil terminal +A1 through coil out terminal –A2 to resistor R to contactor terminal 14 then to J2/P2 – P3/J3 pin “G” continuing to terminal board (TB) terminal 9 through the thermal protectors S2, S3 and refrigerant pressure switches S4, S5 and back through TB-8, thermal protector S1 to TB-7 and through J3/P3 – P2/J2 pin “C” to the -28VDC terminal of the rectifier RR. Thus energizing contactor K1 which supplies the 208 volt, 3-phase, 400 Hz power to the compressor motor B1. After approximately 5 seconds (allowing for compressor motor to come up to speed), the fan switch within sequencer SS recloses restoring the evaporator (vent) circuit. Y-out of sequencer SS also supplies +28VDC power to the condenser motor start time delay relay “TD” terminal 3. Limited power, not enough to energize the contactor, flows through the TD out terminal 1 to terminal +A1 of condenser motor contactor K3 coil and out terminal –A2 to resistor R to contactor term 14 then to J2/P2 pin “G” then as above to -28 VDC terminal of the rectifier RR. The limited power through the TD activates the time delay of approximately 12 seconds and then allows full power through the TD to energize the K3 contactor which supplies the 208 volts, 3-phase, 400 Hz to the condenser fan motor. This sequence of events reduces the overall inrush current by ensuring that no more than one motor starts at the same time and that the largest motor starts first. After the initial start-up of the unit, the one (1) minute delay of sequencer SS is eliminated if the compressor has been “off” for more than one minute. Pin “B” circuit is controlled by the thermostat. Heat Mode (-LO) Without the remote panel thermostat satisfied J8 pin “A” (28VDC+) is electrically connected to J8 pins “D” and “C” by the mode selector switch. 28VDC+ power from rectifier RR flows to evaporator motor (vent) circuit as above and also to the +A1 terminal of heater contactor K4 coil, through the coil and out terminal -0A2 to resistor R to contactor terminal 14 then to J2/P2 pin “F” then as above to -28VDC terminal of the rectifier RR thus energizing heater contactor K4 which supplies the 208V, 3-phase, 400 Hz power to the HR1 element of the electric heater. Pin “D” circuit is controlled by the thermostat. Heat Mode (-HI) Without remote panel thermostat satisfied J8 pin “A” (28VDC) is electrically connected to J8 pins “D”, “E”, and “C” by the mode selector switch. 28VDC+ power from the rectifier RR flow to evaporator motor (vent) circuit and the lo heat circuit as above and also to the +A1 terminal of heater contactor K5 coil through the coil and out terminal –A2 to resistor R to contactor terminal 14 then to J2/P2 pin “F” then as above to -28VDC terminal of the rectifier RR. Thus energizing heater contactor K5 which supplies the 208 volt, 3-phase, 400 Hz power the HR2 and HR3 elements of the electric heater. The pin “E” circuit is controlled by thermostat while the pin “D” circuit is “on” continuously.

REFRIGERATION SYSTEM SERVICING – (LEAK TEST) - Continued 0052-00 SERVICE – LEAK TEST General The entire repaired area should be thoroughly leak tested after repair or replacement of any component, before it is recharged with refrigerant-22. Leak testing is also the method for troubleshooting when a system has lost all or part of its refrigerant charge through an undetermined cause. Testing Method There are two acceptable methods for leak testing the refrigeration system. 1. Refrigerant gas leak detector. If an electronic refrigerant gas leak detector is available it should be used in

accordance with the procedures contained in the detector manufacturer’s instruction booklet.

NOTE

The electronic refrigerant gas leak detector is highly sensitive to the presence of a minute quantity of gas in the air. Due to this factor it is quite effective in the detection of a small leak. However, due to the rapid dispersion of refrigerant gas into the surrounding air, difficulty may be encountered in pinpointing large leaks. The detector must be used in a well-ventilated but draft-free area.

2. Soap solution. In this method, a strong solution of a liquid detergent and water is brushed onto all points of possible

leakage while closely watching for the formation of bubbles. Testing Procedure To perform leak testing by use of the electronic detector, it is necessary that the system be pressurized with a proportion of refrigerant gas. To perform leak testing by use of the soap solution method, the system may be pressurized with dry nitrogen alone. 1. To pressurize a system that has some refrigerant charge, for either leak testing method: a. Remove the hose connection protective caps from the high and low pressure service valves. b. Connect the hoses from a charging manifold to the service valves. c. Connect a nitrogen pressure regulator and nitrogen bottle to the center hose connection of the charging

manifold. d. Open the unit service valves and the charging manifold valves. e. Open the nitrogen tank valve and pressurize the system to 300 PSIG (21.2 kg/cm2). f. Perform leak tests.
