Problems solved by technology

[0002] Generally, the air conditioner must pass factory inspection before leaving the factory. The existing inspection method needs to connect the indoor heat exchanger with the pipeline of the tested machine, and vacuumize the connecting pipeline, and then open the high-pressure cut-off. valve and low-pressure globe valve, at the same time need to connect the power line and communication line, etc., the process is cumbersome and reduces production efficiency
Moreover, it may cause refrigerant leakage or incomplete refrigerant recovery, which will affect the original actual refrigerant amount of the external unit, and the practicability is poor.

Abstract

The invention discloses a detection device and a detection method for an air conditioner without an internal unit. The device for detecting no internal unit of an air conditioner includes: a compressor, a four-way valve, an outdoor heat exchanger, a throttling element, a gas-liquid separator, a first control valve and a second control valve. One end of the first control valve is connected to the throttling element, the other end of the first control valve is connected to the inlet of the gas-liquid separator, one end of the second control valve is connected to the throttling element, and the other end of the second control valve is connected to the indoor The heat exchanger ports are connected. The device for detecting no internal unit of an air conditioner according to the present invention can complete the detection of the air conditioner without connecting the indoor heat exchanger during the factory inspection, which simplifies the detection procedure, improves the production efficiency, and has good practicability.

Description

technical field [0001] The invention relates to the field of home appliances, in particular to an air conditioner without an internal unit detection device and detection method. Background technique [0002] Generally, the air conditioner must pass factory inspection before leaving the factory. The existing inspection method needs to connect the indoor heat exchanger with the pipeline of the tested machine, and vacuumize the connecting pipeline, and then open the high-pressure cut-off. Valves and low-pressure globe valves need to connect power lines and communication lines at the same time. The process is cumbersome and reduces production efficiency. Moreover, it may cause refrigerant leakage or incomplete refrigerant recovery, which will affect the original actual refrigerant amount of the external unit, and the practicability is poor. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. ...
