The compression mechanism includes first and second members cooperating to form a fluid pocket. The volume receives discharge fluid from the fluid pocket. The heat exchanger is in communication with the volume. The fluid conduit is connected to at least one of the volume and the heat exchanger. The thermoelectric device may include a first side in heat-transfer relation with a member at least partially defining the volume and a second side in heat-transfer relation with ambient air and cooperating with the first side to define a temperature gradient generating electrical current in the thermoelectric device. The heat-transfer device may receive electrical current generated by the thermoelectric device and may be in heat-transfer relation with at least one of the heat exchanger and the fluid conduit.

摘要： A cooling system controller controls the capacity of a variable capacity compressor based upon the temperature of a housing being cooled, the suction pressure of the compressor or both of these criteria. The cooling system controller is capable of controlling either single-evaporator or multiple-evaporator refrigeration systems. The multiple-evaporator systems can have evaporators of similar temperatures or of mixed temperatures. The controller also allows the use of one or more condenser fans that are operated in a lead/lag fashion to control the cooling capability of the system.

摘要： A system is provided and may include a compressor having a motor and a refrigeration circuit including an evaporator and a condenser fluidly coupled to the compressor. The system may further include a first sensor producing a signal indicative of one of current and power drawn by the motor, a second sensor producing a signal indicative of a saturated condensing temperature, and a third sensor producing a signal indicative of a liquid-line temperature. Processing circuitry may processes the current or power signal to determine a derived condenser temperature and may compare the derived condenser temperature to the saturated condensing temperature received from the second sensor to determine a subcooling associated with a refrigerant charge level of the refrigeration circuit.
