Be provided with energy converter between the import of said refrigerant separation purifier second cavity and the high-pressure outlet of compressor.
Be provided with drier between the outlet of said refrigerant separation purifier first cavity and the low pressure inlet of compressor.
The exit of said refrigerant separation purifier second cavity is provided with condenser.
The technique effect that the utility model can reach is:
The utility model can be changed the useless refrigeration oil of air conditioning for automobiles exactly, and need not dismantle the inner any parts of air-conditioning, can alleviate maintenance load greatly, ensures the normal operation of air-conditioning.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is that the utility model air conditioning for automobiles refrigeration oil is changed schematic representation of apparatus.
The specific embodiment
As shown in Figure 1, the utility model air conditioning for automobiles refrigeration oil is changing device more, is arranged on the coolant reclaiming machine, comprises pipeline reversing arrangement, compressor, and compressor is provided with low pressure inlet and high-pressure outlet;
The discharging opening of pipeline reversing arrangement is communicated with the import of refrigerant separation purifier first cavity, and the outlet of refrigerant separation purifier first cavity is communicated with the low pressure inlet of compressor; The high-pressure outlet of compressor is communicated with the import of refrigerant separation purifier second cavity, and the outlet of refrigerant separation purifier second cavity is communicated with the refrigerant jar of coolant reclaiming machine; The refrigerant jar is used to provide cold-producing medium; Refrigerant separation purifier second cavity plays the effect of convective heat exchange;
Refrigerant separation purifier first cavity connects the waste oil bottle, and the pipeline between refrigerant separation purifier first cavity and the waste oil bottle is provided with magnetic valve;
The pipeline reversing arrangement connects new oil bottle;
Through a soft pipe connection, be provided with magnetic valve and check valve on the flexible pipe successively between the charging aperture of refrigerant jar and pipeline reversing arrangement; Magnetic valve is used for controlling the circulation of flexible pipe liquid medium, and check valve is used for anti-backflow; The pipeline reversing arrangement has low-pressure end and two ports of high-pressure side, through switching, the refrigerant jar is communicated with the low-pressure end or the high-pressure side of pipeline reversing arrangement;
The exit of refrigerant separation purifier second cavity is provided with condenser, and high temperature and high pressure gas is flowed through to be cooled behind the condenser and condensed into liquid state, conveniently is stored in the refrigerant jar;
