The present embodiment is applied to an air conditioner including both a fluorine pump system and a compressor system, and the schematic diagram of the air conditioner is shown in fig. 2, and the following three operation modes are generally available:

(1) Under the condition of high outdoor temperature, for example, the outdoor temperature is higher than 15 ℃, the air-conditioning compressor system works at the moment, the fluorine pump system does not work, the refrigerant is compressed by the compressor, enters the condenser for cooling, enters the electronic expansion valve for throttling, enters the evaporator for cooling, and returns to the compressor to form a refrigeration cycle.

(2) Under the condition of low outdoor temperature, such as outdoor temperature less than 15 ℃ and more than 5 ℃, the air conditioner compressor system and the fluorine pump system work simultaneously. The refrigerant is compressed by the compressor, enters the condenser for cooling, is pressurized by the fluorine pump, enters the expansion valve for throttling, enters the evaporator for refrigeration, and returns to the compressor to form a refrigeration cycle.

(3) When the outdoor temperature is low, the outdoor temperature is generally set to be less than 5 ℃, the air-conditioning compressor system does not work at the moment, the fluorine pump system works, the refrigerant enters the expansion valve for throttling after being pressurized by the fluorine pump, enters the evaporator for refrigeration, returns to the condenser for cooling, and returns to the fluorine pump for completing the refrigeration cycle.

In the above-described operation modes 2 and 3, the refrigerant is cooled by the condenser and then enters the fluorine pump, and at this time, if a large amount of gaseous refrigerant enters the fluorine pump, the fluorine pump may malfunction. The air conditioning pipeline provided by the embodiment is connected between the condenser and the fluorine pump, when the refrigerant enters the outer pipe after passing through the condenser, the liquid refrigerant is deposited at the bottom of the outer pipe under the action of gravity and flows to the fluorine pump through the inner pipe, the gas refrigerant is blocked by the liquid refrigerant and the inner pipe and cannot enter the fluorine pump, and the fluorine pump is ensured not to have a fault that the gaseous refrigerant enters the fluorine pump.
