Problems solved by technology

[0004] When the air-conditioning heat recovery system is in the complete heat recovery mode, the indoor unit 1 has cooling and heating modes at the same time, and the sum of the heating capacity of the indoor unit 1 in the heating mode is basically equal to the sum of the cooling capacity of the indoor unit 1 in the cooling mode. At this time, there is no need for the heat exchanger 8 o

Abstract

The embodiment of the invention discloses an air conditioner heat recycling system which comprises electric control valves and a heat exchanger. At least one electric control valve is connected between a liquid outlet pipe of a heat dissipation driving module and a low-pressure air pipe in series, and a first pipeline is formed. At least one electric control valve is connected between a liquid inlet pipe of the heat dissipation driving module and a high-pressure air pipe in series, and a second pipeline is formed. The heat exchanger is connected with the first pipeline and the second pipeline, so that heat of a high-temperature refrigerant in the second pipeline is transferred to a low-temperature refrigerant in the first pipeline. According to the air conditioner heat recycling system, under the complete heat recycling mode, heat dissipation of the heat dissipation driving module can be achieved, the situation that the system is damaged due to excessively high temperature of the heat dissipation driving module is avoided, and the working stability and safety of the air conditioner heat recycling system are improved.
