摘要： A method for determining when to initiate a defrost mode of a heat pump includes monitoring a heating capacity of an evaporator of the heat pump during operation of the heat pump in a heating mode, determining a threshold associated with the heating capacity, and initiating a defrost mode when the heating capacity of the evaporator is less than or equal to the threshold.

摘要： A CO2 cooling system includes a compression stage in which CO2 refrigerant is compressed; a cooling stage in which the CO2 refrigerant releases heat; a CO2 liquid receiver in which the CO2 refrigerant is accumulated in liquid and gaseous states; an evaporation stage in which the CO2 refrigerant, having released heat in the cooling stage, absorbs heat. The evaporation stage has first and second evaporation sectors; a first metering device for feeding CO2 refrigerant into the first evaporation sector at a first pressure; and a second metering device for feeding CO2 refrigerant into the second evaporation sector at a second pressure. The first metering device and the second metering device are operated independently from one another. A plurality of CO2 transfer lines connects the compression stage, the cooling stage, the CO2 liquid receiver and the evaporation stage. The CO2 refrigerant is circulable in a closed-loop circuit.

摘要： The present disclosure provides a method of controlling an air conditioning system of a vehicle. The method includes controlling a compressor to adjust a flow of refrigerant discharged from the compressor to obtain a target refrigerant pressure responsive to an actual refrigerant pressure upstream an inlet of an electric expansion valve. The method also includes controlling the valve to adjust the flow entering an evaporator to obtain a target evaporator surface temperature responsive to an actual evaporator temperature.

摘要： An operation method of a constant-temperature liquid circulation apparatus includes: performing control such that the fan is not activated, or is activated to maintain a minimum rotation speed when a refrigerant pressure measured by the pressure sensor does not reach a reference pressure region after the compressor is activated; controlling the refrigerant pressure by performing inverter control on a rotation speed of the fan when the refrigerant pressure reaches the reference pressure region; and controlling a rotation speed of the compressor to be reduced from a high rotation speed which is a rotation speed during a steady operation while maintaining the rotation speed of the fan at a maximum rotation speed when the refrigerant pressure continues to further rise and exceeds an upper limit value even after the rotation speed of the fan reaches the maximum rotation speed.

摘要： Provided is a refrigeration cycle wherein, when an orifice is disposed within a refrigeration circuit, and a differential pressure between the upstream side and the downstream side of the orifice is detected using two pressure sensors, the difference between the characteristics of the pressure sensors can be adequately and easily absorbed in software, to accurately determine an actual differential pressure, so that the flow rate of refrigerant and the torque of a compressor can be accurately estimated. The refrigeration cycle wherein the orifice is provided within a refrigerant circuit, and the pressure sensors are respectively provided on the upstream side and the downstream side of the orifice, is characterized in that, with regard to output characteristics representing the relationship between the detected pressure and the sensor output of each pressure sensor, the difference between the output characteristics of one pressure sensor and the output characteristics of the other pressure sensor is determined based on the outputs of both pressure sensors at a condition where the flow of refrigerant is stopped.

摘要： A refrigeration equipment includes a vapor compression type of refrigerant circuit that prevents a decline in refrigeration ability in user side heat exchangers when the refrigerant condensed by a heat source side heat exchanger is reduced in pressure and sent to the user side heat exchangers. An air conditioner includes a refrigerant liquid junction line and a refrigeration gas junction line, a heat source side expansion valve, a cooler, and a first pressure detection mechanism. The heat source side expansion valve reduces the pressure of the refrigerant that is condensed in the heat source side heat exchanger and sent to the user side heat exchangers. The cooler cools the refrigerant that is condensed in the heat source side heat exchanger and sent to the user side heat exchangers. The first pressure detection mechanism detects the pressure of the refrigerant after the pressure thereof has been reduced by the heat source side expansion valve.
