Embodiment approach 1

[0019] figure 1 It is a schematic configuration diagram showing an example of the refrigerant circuit configuration of the air conditioner 500 according to the embodiment of the present invention. based on figure 1 , the air conditioner 500 will be described. The air conditioner 500 is installed in, for example, a building or an apartment, and can perform a cooling operation or a heating operation using a refrigeration cycle (heat pump cycle) that circulates a refrigerant.

[0020] The air conditioner 500 has a heat source side unit 100, and a plurality of units (in figure 1 In the middle are two) load side units 300a, 300b. The heat source side unit 100 and the load side units 300 a and 300 b are connected by a gas extension pipe 401 and a liquid extension pipe 402 . The gas extension pipe 401 is composed of a gas main pipe 401x, a gas branch pipe 401a, and a gas branch pipe 401b. The liquid extension pipe 402 is composed of a liquid main pipe 402x, a liquid branch pipe ...

Abstract

The refrigeration cycle device of the present invention includes a refrigerant circuit, a control device, a bypass pipe, a refrigerant cooler, a second expansion device, and a temperature sensor for the control device. In addition, the control device increases the opening degree of the second throttle device when the opening degree of the second throttle device is controlled to be an indicated opening degree equal to or lower than the set opening degree, and when the temperature detected by the temperature sensor of the control device is equal to or lower than the set temperature. The opening degree of the second throttling device, and returns to the foreign matter release control indicating the opening degree after increasing.

Description

technical field [0001] The present invention relates to a refrigeration cycle device using a refrigerant cooling control device. Background technique [0002] Conventionally, the following technology is known for cooling the control device, that is, a part of the refrigerant is diverted from the main flow on the high-pressure side of the refrigerant circuit, and after dissipating heat in the pre-cooling heat exchanger, the refrigerant that has dissipated heat is cooled to the refrigerant. The controller flows to exchange heat with the control device, thereby cooling the control device. The refrigerant flowing out of the refrigerant cooler flows toward the suction side of the compressor via an expansion device that controls the refrigerant flow rate of the refrigerant cooler. The control device includes a heat-generating semiconductor element such as SiC, and the temperature of the control device rises due to heat generated in the semiconductor element. When the temperature...
