摘要： In a heat-source unit (15) which heats heating-medium water inside of a heat storage tank (16), a refrigerant circuit (30) is provided with a low-stage compressor (52), a high-stage compressor (62) and an expander (65) for power recovery. The low-stage compressor (52) is rotated by an electric motor (54) connected to a drive shaft (53) thereof. The high-stage compressor (62) is rotated by an electric motor (64) and the expander (65) connected to a drive shaft (63) thereof. A high-stage control section of a controller (90) adjusts the rotational speed of the high-stage compressor (62) in such a way that a value measured by an outlet water-temperature sensor (77) becomes a target temperature. A low-stage control section adjusts the rotational speed of the low-stage compressor (52) in such a way that a value measured by a discharge pressure sensor (74) becomes a target high pressure.

摘要： To provide a refrigeration apparatus that suppresses noise that occurs when reverting to a heating operation and with which it is easy to ensure heating capacity. An air conditioner (1) that is a refrigeration apparatus has, in a refrigerant circuit (10), a compressor (11), an outdoor heat exchanger (13) that functions as an evaporator in a heating operation, an indoor heat exchanger (16) that functions as a condenser in the heating operation, and a four way valve (12). The refrigerant circuit (10) is configured in such a way that a high-pressure value of the refrigerant circuit (10) in a defrost operation is lower than a high-pressure value of the refrigerant circuit (10) in the heating operation. An end-of-defrost frequency decrease rate, which is a rate of decrease in the operating frequency of the compressor (11) in the defrost operation, is set faster than a normal frequency decrease rate, which is a rate of decrease in the operating frequency of the compressor (11) in the heating operation.

摘要： A refrigeration system includes a two-stage linear compressor having a first piston disposed in a first cylinder and a second piston disposed in a second cylinder. The linear compressor is operable in an economizer cycle wherein the first piston operates as a first stage of the economizer cycle and the second piston operates as a second stage of the economizer cycle. A controller is coupled to the linear compressor to control a volume flow ratio of the linear compressor. The controller stores a plurality of coefficients of performance for a range of particular operating conditions of the linear compressor and each coefficient of performance corresponds to a desired volume flow ratio and a desired secondary evaporating temperature. Based upon measured operating conditions of the linear compressor, the controller determines a highest coefficient of performance from the plurality of coefficients of performance and varies operation of at least one of the first and second pistons to achieve the desired volume flow ratio.
