摘要： The exhaust heat recovery system (1) comprises: an evaporator (2); an expander (3); a condenser (5); a circulation pump (7); a circulation flow path (6) for circulating a working medium therethrough; cooling medium piping (8) which is connected to the circulation flow path (6) and causes a portion of the working medium sent out from the circulation pump (7) to be diverted to flow into the condenser (5); a cooling-side opening/closing valve (13) for switching between a state in which the working medium can flow into the cooling medium piping (8) and a state in which the working medium cannot flow thereinto; and a control unit (10) for performing the switching control of the cooling-side opening/closing valve (13). When a condition under which the temperature of the working medium flowing into the condenser (5) becomes higher than or equal to a predetermined temperature is satisfied, the control unit (10) controls the cooling-side opening/closing valve (13) to switch to the state in which the working medium can flow into the cooling medium piping (8).

摘要： An exhaust heat recovery type of air-conditioning apparatus includes: an air-conditioning-side refrigerant circuit including a first flow switching device, a second flow switching device, and an exhaust-heat recovery heat exchanger connected in parallel to an outdoor heat exchanger and an indoor heat exchanger; and a refrigeration-side refrigerant circuit. The first flow switching device causes the outdoor heat exchanger to communicate with one of a discharge side and a suction side of a first compressor through a pipe. The second flow switching device causes the indoor heat exchanger to communicate with one of the discharge and suction sides of the first compressor through a pipe. The exhaust-heat recovery heat exchanger is connected to the suction side of the first compressor through a pipe, and causes heat exchange between refrigerants. Because of the above configuration, the exhaust heat recovery type of air-conditioning apparatus can use exhaust heat in any of operation modes.

摘要： An oil-cooled gas compressor provided with a compressor body, an oil separator that separates out oil from a compressed gas, a gas pipe for sending the compressed gas, from which oil has been separated out by the oil separator, to a user, and an oil pipe for returning, to the compressor, the oil separated out by the oil separator. An air-cooled heat exchanger for cooling the aforementioned oil, a controllable-speed cooling fan for blowing cooling air at said air-cooled heat exchanger, and a waste-heat-recovery heat exchanger, provided upstream of the air-cooled heat exchanger, for recovering heat from the oil flowing through the abovementioned oil pipe, are also provided. The speed of the cooling fan is controlled so as to bring the temperature of the compressed gas discharged from the compressor body to within a prescribed range. It is possible both to recover waste heat from the oil heated by being used to cool the compressor and to suppress compressor temperature fluctuations, even if the load on the waste-heat-recovery equipment varies.
