Abstract: A conditioned air delivery system is provided for parked aircraft. The system can accommodate elevated thermal loads while maintaining operation, albeit with reduced flow rates or slightly elevated temperatures. When temperature set points are not reached or cannot be maintained, a second compressor of a refrigeration unit is operated in parallel with a first compressor. When refrigerant pressure becomes excessive, a second fan is operated that is associated with a condenser of the system. Still higher pressures, indicative of higher thermal loads, can cause the system to shut down operation of one of the compressors, reducing the overall cooling capacity of the system, while maintaining the supply of refrigerated air to the aircraft. The airflow may be reduced to maintain an air temperature at or near the desired temperature. Coordination of several parallel and redundant refrigeration units may be provided with a single blower and coordinated control.

Abstract: A heating/cooling system includes a closed circuit refrigeration system including an evaporator. Water circulating through a closed water circuit exchanges heat with refrigerant in the evaporator, cooling the water for a cooling application. The water can also be heated by a boiler, and the heated water is used to heat a space. A water pump flows the water through the water circuit. When a current sensing relay detects a power failure, a boiler control algorithm is initiated to "trick" a motor of the compressor into believing the heating/cooling system is operating in a heating mode. Therefore, a compressor failure alarm is not generated. The water pump is powered by a battery pack during the power failure. Water continues to flow through the water circuit, preventing the water from freezing.

Abstract: A direct current (DC) powered variable capacity air conditioning system is provided. The system includes a plurality of temperature sensors for monitoring the temperature of various components, locations and air flows within the system. The system additionally includes an integrated controller board that substantially simultaneously controls a variable speed DC compressor motor, a variable speed condenser air mover and a variable speed evaporator air mover in response to inputs from the sensors. By substantially simultaneously controlling the variable speed DC compressor motor, the variable speed condenser air mover and the variable speed evaporator air mover, the system substantially simultaneously controls at least one of a temperature and a volume of an evaporator output air flow. Thus, the system provides a continuum of evaporator output air flow temperatures and capacities for maintaining an approximately constant temperature within an enclosed environment.

Abstract: A suction modulation valve is throttled when conditions in a refrigerant system indicate that an undesirable amount of liquid refrigerant might otherwise be delivered to the compressor. As an example, the throttling would occur at start-up, among other conditions. Throttling the suction modulation valve reduces the amount of refrigerant reaching the compressor and thus ensures that any liquid refrigerant would be likely “boiled off” before raising any problems in the compressor. Other control steps can also be performed to alleviate flooded compressor operation with liquid refrigerant. Such steps , for example, can consist of: actuating heaters, discharge valve throttling, by-passing refrigerant from intermediate compression point back to suction, controlling the speed of the condenser fan can be performed independently or in combination including the suction modulation valve throttling.
