When reduce refrigerant circuit length to the greatest extent, reduce refrigerant circulating resistance, reduce system power dissipation, improve system overall work
Energy.
Non-thermal switch mode: high temperature refrigerant lateral and the setting of low-temperature refrigerant lateral are defeated in high temperature refrigerant
Out in the heat exchange mode specific implementation of main pipeline: when refrigeration cycle, triple valve controls the first common mouth and leads with commutation mouth
Logical, low-temperature refrigerant flows through triple valve after indoor heat exchanger exchanges heat, and flows to low-temperature refrigerant lateral, is then return to
In outdoor unit pipeline, loop circuit heat pipe carries out heat release；When heating circulation, triple valve controls the second common mouth and is connected with commutation mouth, high
The high temperature refrigerant lateral being arranged in warm refrigerant flow direction room, passes through triple valve, flows to indoor heat exchanger, heat pipe dress
It sets and absorbs heat.Such design, low-temperature refrigerant lateral and high temperature refrigerant lateral are arranged parallel, guarantee heat exchange
