Embodiment Construction

[0019] see Figure 1-2 , the test tooling of the indoor unit of the air conditioner of the present invention comprises: a condenser group 6, a compressor 4, a four-way valve 5, wherein the condenser group 6 is used to form a refrigeration unit with the evaporator group 11 in the indoor unit of the air conditioner to be tested. The agent circulation loop, the compressor 4 is connected or disconnected in series with the intake side pipeline of the condenser group 6 through the four-way valve 5 .

[0020] further, Figure 1-2 As shown in , the test fixture of the present invention also includes: a first shut-off valve 8 and a second shut-off valve 3 . The first shut-off valve 8 is connected on the liquid outlet side pipeline of the condenser group 6 (communicated with the liquid outlet 62 of the condenser group), the second shut-off valve 3, the suction port 41 of the compressor 4, the discharge port of the compressor 4 The air port 42 and the air inlet 61 of the condenser grou...

Abstract

The invention provides a test tool for an air conditioner indoor unit, which is provided with a condenser unit for forming a refrigerant circulation loop with an evaporator unit in the air conditioner indoor unit and is further provided with a compressor and a four-way valve, wherein the compressor is selectively and serially connected or disconnected with an air inlet pipeline of the condenser unit via the four-way valve. On the other hand, the invention further provides a method for online test and refrigerant recovery of the air conditioner indoor unit, and the air conditioner indoor unit is the indoor unit with the compressor built therein. The method comprises the following steps: 1, connecting the indoor unit with the test tool provided by the invention in order to perform online test on the indoor unit; and 2, reversing the four-way valve after the online test is completed, so that the residual refrigerant in the indoor unit is recovered by the compressor to the condenser unit of the test tool. The test tool provided by the invention not only realizes the online test of the indoor unit, but can also recovers the refrigerant in the indoor unit, in addition, the refrigerant recovery cost is low as the fluorine recovery machine is not used.

Description

technical field [0001] The invention relates to a testing tool for an indoor unit of an air conditioner, and a method for on-line testing and refrigerant recovery of the indoor unit of the air conditioner. Background technique [0002] For base station air conditioners, because they need to be used in many unattended remote areas, anti-theft has become a key consideration for base station air conditioners. For this reason, the compressor is placed indoors, and the existing ordinary air conditioner production lines and test tools cannot be tested online. Receive fluorine. [0003] For this kind of indoor unit air conditioner with built-in compressor, ordinary air conditioner inner unit production line cannot be produced, and it can only be produced in the outer unit line. The indoor unit of the air conditioner needs to be connected to the external unit, but using this external unit that matches the internal unit built into the compressor, fluorine cannot be collected after t...
