Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1.
It is a kind of total heat recovery and accurately to adjust the air-conditioning system of recuperation of heat amount, including outdoor unit and indoor unit, the room
Outer machine includes compressor 1, main four-way valve 3, auxiliary four-way valve 4, outdoor heat exchanger 8 and gas-liquid separator 12；The indoor unit includes
First indoor heat exchanger 10 and the second indoor heat exchanger 11.
The outdoor heat exchanger 8 be it is two or more, be connected in parallel.The input end of one of outdoor heat exchanger is equipped with electricity
Dynamic ball valve 5, to adjust the refrigerant flow for flowing into the outdoor heat exchanger；The input end of other outdoor heat exchangers is equipped with solenoid valve
6, the input end can be opened and closed, control refrigerant flows into these outdoor heat exchangers.
The liquid pipe end of first indoor heat exchanger 10 and the second indoor heat exchanger 11 simultaneously passes through liquid pipe and the room after connecing
The outlet of external heat exchanger 8 is connected, and tracheae end is connected respectively to the E mouth of the main four-way valve 3 and the C mouth of the auxiliary four-way valve 4；
The D mouth of the main four-way valve 3 and the D mouth of auxiliary four-way valve 4 and the exhaust outlet that the compressor 1 is connected to after connecing.
