Description
Technical field
This utility model relates to refrigerating transport vehicle, especially relates to a kind of one drag two cold preservation unit for refrigerating transport vehicle.
Background technology
Refrigerator car is widely used in that frozen food, milk product, vegetable and fruit, vaccine medicine etc. are freezing or the highway transportation of fresh-keeping goods.Vehicle is closed van, has independent refrigeration unit.Conventional automobile production producer only considers the installation site of driver's cabin compressor of air conditioner, if later stage client installs cold preservation unit and is accomplished by installing on the engine a compressor again, but Some vehicles cannot install two compressors due to distribution engine reason.Have no idea just to be dismantled by driver's cabin compressor of air conditioner, the compressor of cold preservation unit is installed.Such driver's cabin air-conditioning just cannot use, if summer particularly south region, the working environment of driver's cabin driver and conductor, with regard to very severe, works under this hot environment for a long time and is easy to affect the healthy of driver and conductor and duty, even affect the safety of driving.
Summary of the invention
This utility model purpose is in that to provide a kind of one drag two cold preservation unit for refrigerating transport vehicle using a compressor respectively driver's cabin and cold closet to be freezed.
For achieving the above object, this utility model can take following technical proposals:
One drag two cold preservation unit for refrigerating transport vehicle described in the utility model, including compressor and the A/C evaporator being arranged in transport vehicle driver's cabin；It is provided with refrigeration evaporator in transport vehicle refrigerating carriage body, described A/C evaporator is connected with the first check valve and the second check valve respectively through pipeline with refrigeration evaporator, and the media outlet of described first check valve and the second check valve is connected with the medium entrance of compressor respectively through pipeline；The media outlet of described compressor is provided with and communicated with two-way pipeline, and the first pipeline is connected with the medium entrance of described refrigeration evaporator by connecting the defrost valve arranged；Second pipe is connected with the medium entrance of A/C evaporator by being sequentially communicated the condenser of setting, reservoir, device for drying and filtering, liquid-sighting glass, the first switch valve and the first expansion valve, being provided with and communicated with the 3rd pipeline on second pipe between described liquid-sighting glass and the first switch valve, described 3rd pipeline is connected with the medium entrance of refrigeration evaporator by the second switch valve and the second expansion valve being sequentially communicated setting.
This utility model advantage is in that cannot install the vehicle of two refrigeration compressors for Refrigerated Transport car engine, only need a compressor just can ensure again the normal operation of cold preservation unit while retaining driver's cabin air-conditioning, thus ensureing traffic safety and the riding comfort of driver and conductor.

Detailed description of the invention
As shown in Figure 1, 2, the one drag two cold preservation unit for refrigerating transport vehicle described in the utility model, including compressor 1 and the A/C evaporator 3 being arranged in transport vehicle driver's cabin 2；It is provided with refrigeration evaporator 5 in transport vehicle cold preservation envelope 4, described A/C evaporator 3 is connected with the first check valve 6 and the second check valve 7 respectively through pipeline with refrigeration evaporator 5, and the media outlet of described first check valve 6 and the second check valve 7 is connected respectively through the medium entrance of pipeline with compressor 1；The media outlet of described compressor 1 is provided with and communicated with two-way pipeline, and the first pipeline 8 is connected with the medium entrance of described refrigeration evaporator 5 by connecting the defrost valve 9 arranged；Second pipe 10 by being sequentially communicated the condenser 11 of setting, reservoir 12, device for drying and filtering 13, liquid-sighting glass the 14, first switch valve 15 are connected with the medium entrance of A/C evaporator 3 with the first expansion valve 16, being provided with and communicated with the 3rd pipeline 17 on second pipe 10 between described liquid-sighting glass 14 and the first switch valve 15, described 3rd pipeline 17 is connected with the medium entrance of refrigeration evaporator 5 with the second expansion valve 19 by being sequentially communicated the second switch valve 18 of setting.
Owing to being respectively arranged with refrigeration evaporator 5 and A/C evaporator 3 in transport vehicle driver's cabin 2 and transport vehicle cold preservation envelope 4, the purpose that temperature control realization is lowered the temperature respectively therefore can be passed through.Compressor 1 media outlet gases at high pressure out, second pipe 10 by separating after condenser fan 20 heat radiation of condenser 11 after reservoir 12, device for drying and filtering 13, liquid-sighting glass 14 again, one tunnel the first switch valve the 15, first expansion valve 16 enters A/C evaporator 3, through evaporating fan 21 heat exchange of A/C evaporator 3；The 3rd pipeline 17 of separately leading up to enters refrigeration evaporator 5 through second switch valve 18 and the second expansion valve 19, through evaporating fan 22 heat exchange of refrigeration evaporator 5；After the first check valve 6 and the second check valve 7 are joined, return the medium entrance of compressor 1 respectively through pipeline from A/C evaporator 3 and refrigeration evaporator 5 refrigeration working medium out.
