Claims

[Claims for Utility Model Registration] 1. An air conditioner in which a compressor, a four-way valve, an indoor heat exchanger, an expansion valve, an outdoor heat exchanger, etc. are sequentially connected via refrigerant piping to form a refrigeration cycle, The refrigerant pipe connecting the four-way valve and the heat exchanger is connected to the refrigerant pipe on the discharge side or suction side of the compressor by a bypass path, and a balance valve is provided in the middle of this bypass path. An air conditioner characterized in that the air conditioner is set to open when a refrigerant pressure difference is below a set value. 2. The bypass path connects the refrigerant pipe connecting the four-way valve and the indoor heat exchanger to the refrigerant pipe on the suction side of the compressor in a manner that bypasses the four-way valve. Air conditioner. 3. The air conditioner according to claim 1, wherein the bypass path connects the four-way valve and the refrigerant pipe connecting the outdoor heat exchanger and the compressor suction side refrigerant pipe so as to bypass the four-way valve. . 4. The air conditioner according to claim 1 of the utility model registration, in which the bypass path connects the refrigerant pipe connecting the four-way valve and the outdoor heat exchanger and the refrigerant pipe on the discharge side of the compressor so as to bypass the four-way valve. Machine. 5. The air conditioner according to claim 1 of the utility model registration, in which the bypass path connects the refrigerant pipe connecting the four-way valve and the indoor heat exchanger and the refrigerant pipe on the discharge side of the compressor so as to bypass the four-way valve. Machine.
