摘要： To provide a safe refrigeration cycle apparatus which uses a flammable refrigerant and in which the flammable refrigerant is prevented from, for example, igniting with the flame of, for example, a burner during replacement of a component of the refrigeration cycle apparatus. Disclosed is a part replacement method for replacement of a part of a refrigeration cycle apparatus 100 including a refrigerant circuit in which a flammable refrigerant is circulated and a container connecting device 28 for controlling the refrigerant such that the refrigerant is allowed to flow out of the refrigerant circuit. The method includes a refrigerant recovery step of allowing the refrigerant to flow out of the refrigerant circuit through the container connecting device 28, a pressure reduction step of connecting a pressure reducing device 29B to the container connecting device to reduce a pressure in the refrigerant circuit until the pressure in the refrigerant circuit reaches a set pressure or a setting time is reached, and a part replacement step of removing the part from the refrigerant circuit by heating to replace the part.

摘要： The opening control of a pressure reducing expansion valve 40 is performed only when the refrigerant pressure on the high-pressure side in an outdoor unit 10 is high during a cooling operation. The opening of the valve 40 is determined on the basis of the driving frequency of a compressor 16 at that point in time, i.e., the volumetric flow rate of a refrigerant. A pressure reduction in the valve 40 is suppressed when the volumetric flow rate of the refrigerant is large and a pressure loss in a communication pipe 30 is large, and the pressure reduction in the valve 40 is increased when the volumetric flow rate of the refrigerant is small and a pressure loss in a communication pipe 30 is small, whereby the amount of pressure reduction of the refrigerant is adjusted in the total refrigerant circuit from the compressor 16 to an indoor expansion valve 22.

摘要： The invention discloses a compressor over-load protection control method. The method includes that: the state of a compressor is detected (S101); it is judged whether the compressor is under over-load protection (S102); and if the compressor is under the over-load protection, fluorine shortage protection is shielded (S103). A compressor over-load protection control apparatus includes: a detection unit (10), configured to detect the state of a compressor; a judgement unit (20), configured to judge whether the compressor is under over-load protection; and a shielding unit (30), configured to shield fluorine shortage protection if the compressor is under the over-load protection. By means of the method and apparatus, the problem in the relevant art that a fluorine shortage false alarm is easily triggered is solved, thereby achieving the effect of preventing the fluorine shortage false alarm when the compressor is under the over-load protection.
