摘要： In a refrigerating cycle apparatus and control method thereof, a controller sets a high-pressure pressure target value from thermal load and temperature conditions based on refrigerant information that has been obtained from detectors, and controls at least one of a rotational frequency of a compressor, a degree of opening of an electronic expansion valve, a rotational frequency of an outdoor fan, or a rotational frequency of an indoor fan to match a high-pressure pressure to the high-pressure pressure target value that has been set. Here, a threshold value is set when the high-pressure pressure target value is set, and a method for setting the high-pressure pressure target value is modified depending on whether the high-pressure pressure is greater than or equal to the threshold value or less than the threshold value when the high-pressure pressure target value is decided.

摘要： When using at least one of heat exchangers related to heat medium that exchange heat between a heat source side refrigerant and a heat medium as an evaporator, in a case where an air-conditioning apparatus has detected, in the heat exchanger related to heat medium that functions as the evaporator, an evaporating temperature of the heat source side refrigerant which causes the temperature of the heat medium passing through this heat exchanger related to heat medium to become equal to or lower than a freezing temperature, the air-conditioning apparatus performs a heat medium anti-freezing operation by blocking entry of the heat source side refrigerant into the heat exchanger related to heat medium that functions as the evaporator, and causing the heat source side refrigerant to flow to a bypass pipe.
