[0031] The fluorine pump dual-cycle air conditioner includes an evaporator, a condenser, a compressor, a fluorine pump, a one-way valve, a liquid storage tank, a throttling device and a valve. When the outdoor temperature is high, the valve and the fluorine pump are closed, and the compressor is turned on. The liquid refrigerant in the evaporator absorbs the heat of the chilled water and evaporates. After being compressed by the compressor, it is transported to the outdoor evaporative condenser. After cooling and condensing into liquid, it is collected in the liquid storage tank. Then it enters the throttling device through the one-way valve pipeline, and enters the evaporator after reducing pressure and temperature, absorbing the heat of the chilled water and evaporating, forming a compressor refrigeration cycle. When the outdoor temperature drops to a low enough level, the compressor is closed, and the valve and fluorine pump are turned on. The liquid refrigerant in the evaporator absorbs the heat of the chilled water and evaporates. Under the action of volume expansion, the gaseous refrigerant flows along the evaporator outlet pipeline, through the valve, and is transported to the outdoor evaporative condenser. After cooling and condensing into liquid, it is collected in the liquid storage tank. Then it is transported into the throttling device through the fluorine pump, and enters the evaporator after reducing pressure and temperature, absorbing the heat of the chilled water and evaporating, forming a fluorine pump refrigeration cycle.
