    摘要： An engine driven heat pump is such that when a self-sustaining switch is turned on during power failure, and a self-sustaining signal is received, it switches to a self-sustaining mode and start an engine and a generator, and when output power from an inverter is received, it supplies the output power to a power supply circuit and a battery charging circuit by means of an independent power supply relay, and it supplies the output power to the outside via an independent output unit, and during the supply of the output power, it maintains cutoff with respect to connection between a system, and the power supply circuit and the battery charging circuit by means of a system cutoff relay and maintain the output of the output power until the self-sustaining signal is interrupted, and it recovers the connection when power is restored and the output power is interrupted.

    摘要： A fuel-powered engine is provided to drive a mobile air conditioning or refrigeration unit such as a portable chiller, a container refrigeration unit, a portable packaged system, a transport tractor-trailer or truck refrigeration unit, etc. A control rapidly changes the engine speed between the predefined set of discreet engine speeds to precisely adjust the capacity of the refrigerant system. If the engine operates only at a single speed, then the control cycles the engine between this operating speed and a zero speed (the engine is shut off). If the engine can operate at multiple discreet speeds, then the control can cycle the engine between any of these speeds (including a zero speed). When a lower capacity is desirable, the engine operates for a longer time interval at a lower speed, and when a higher capacity is desirable, the engine operates for a longer period of time at a higher speed. The cycle rate is selected to control the comfort (e.g. temperature and/or humidity) of the conditioned environment within the specified tolerance band, while conforming to the reliability requirements.

    摘要： A control unit for variable displacement compressors is used for two independent air conditioning cycles, wherein two compressors 1, 11 driven by a common external drive source 8 include electromagnetic displacement control valves 6, 16, respectively. By controlling these control valves by ECU 7, the displacement of the compressor is variable. When the air temperature is higher than a predetermined temperature T0, both of the compressors are subjected to the variable displacement operation even though one of them is unnecessary for the air conditioning operation. On the contrary, if the outer air temperature is lower than the predetermined temperature, only one compressor, needed for the air conditioning operation, is subjected to the variable displacement operation, while the other compressor is subjected to the minimum displacement operation.

    摘要： In a refrigerant cycle system with a hot gas heater cycle, a pressure difference (&Dgr;Pd) between a high-pressure side refrigerant pressure of the hot gas heater cycle at a start of a heating mode and a high-pressure side refrigerant pressure of the hot gas heater cycle at a predetermined time after the start of the hot-gas heating mode is calculated. When the pressure difference (&Dgr;Pd) is in a predetermined range, it can be determined that the refrigerant is in a normal state. In this case, an electromagnetic clutch is turned on, and a compressor operates. On the other hand, when the pressure difference (&Dgr;Pd) is outside the predetermined range, it can be determined that the refrigerant is in a shortage state. In this case, the electromagnetic clutch is turned off, and the operation of the compressor is stopped.
