Auxiliary exhaust port 82 accesses the second exhaust access of the second air-conditioning system 10 through the condenser of the second air-conditioning system.
Meanwhile the return line of the compressor is equipped with dispenser.First exhaust access and second exhaust access exist
Converge in the return line of dispenser inlet, two sets of air-conditioning systems share a liquid separator of compressor.
Air-conditioning system at work, enters the first air-conditioning system by the compressed gas that main vent 81 is discharged in the present embodiment
9 first exhaust access is entered the second exhaust access of the second air-conditioning system 10 by the compressed gas that auxiliary exhaust port 82 is discharged.
Two temperature air-conditioning system provided in this embodiment, the original suction airway dysfunction of compressor is constant, keeps another way row
Gas is discharged from the exhaust pipe of shell upper end, connect with the second servo loop of refrigeration system after shell, and it is logical to form second exhaust
Road.
Existing compressor only has the function of one air-breathing parameter of output and an exhaust parameter, if desired realizes multiple suctions
The output of gas parameter or exhaust parameter then needs multiple compressors to combine to realize, two temperature in the prior art such as shown in Figure 4
Air-conditioning system, two groups of air-conditioning systems are independent of one another, realized respectively by two groups of compressors, while cost performance is not high, to installation
Space is also more demanding.The utility model makes a compressor have the double function of single suction, can effectively substitute former needs two
Compressor is just able to achieve the two temperature air-conditioning system of the double-exhaust parameter of driving.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
