Claims

[Scope of Claim for Utility Model Registration] (1) A refrigeration cycle in which a compressor, a condenser, a pressure reducer, and an evaporator are sequentially connected in a ring through refrigerant piping, a heat exchanger in which heated brine circulates, and an air passage. and a blower device having an evaporator and a heat exchanger,
In a control device for an air conditioner configured to perform cooling using a refrigeration cycle during cooling operation and to perform heating by circulating brine during heating operation, a solenoid valve that controls the flow of brine to a heat exchanger; 1. A control device for an air conditioner, comprising: a control unit that opens the solenoid valve during heating operation, and opens the solenoid valve for a certain period of time at predetermined intervals during cooling operation. (2) It has a single radiator that integrates the evaporator of the refrigeration cycle, which consists of a compressor, condenser, pressure reduction device, and evaporator, and a heat exchanger in which heated brine circulates. A solenoid valve that controls the flow of brine to a heat exchanger in a control device for an air conditioner that performs cooling from a radiator using a cycle, and during heating operation, circulates brine to perform heating from the radiator. 1. A control device for an air conditioner, comprising: a controller that opens the solenoid valve for a certain period of time at predetermined intervals and maintains the solenoid valve in an open state during heating operation.
