Problems solved by technology
The requirement for the liquid return hole diameter in low-temperature conditions such as ultra-low temperature heating is exactly the opposite of that in high-temperature conditions such as refrigeration, so the existing liquid storage tank cannot meet the needs of heat pump systems operating at wide ambient temperatures

Embodiment Construction
[0027] In order to simplify the description process, the orientation terms such as up and down used in this embodiment refer to the orientation of the liquid storage tank in use.
[0028] see in conjunction Figures 1 to 7 As shown, according to an embodiment of the present invention, a liquid storage tank is provided, including a housing 1 and a connecting pipe 2, the connecting pipe 2 is connected to the housing 1, and one end of the connecting pipe 2 extends into the In the cavity formed by the casing 1, an overflow structure is also included, and the overflow structure divides the area of the connecting pipe insertion end of the casing 1 into a first liquid storage area 5 and a second liquid storage area 6, so that The mixture of liquid refrigerant and lubricating oil in the first liquid storage area 5 can be diverted from the first liquid storage area 5 to the second liquid storage area through the overflow structure after the liquid level rises to a preset height 6. ...

The invention provides a liquid storage tank, a compressor and an air conditioner. The liquid storage tank includes a casing and a connecting pipe, the connecting pipe is connected with the casing, and one end of the connecting pipe extends into the cavity formed by the casing, and also includes an overflow structure, the The overflow structure divides the area of the connecting pipe insertion end of the casing into a first liquid storage area and a second liquid storage area, so that the mixture of liquid refrigerant and lubricating oil in the first liquid storage area rises to a predetermined level at the liquid level. After the height is set, it can flow from the first liquid storage area to the second liquid storage area through the overflow structure. The liquid storage tank, the compressor and the air conditioner according to the present invention not only ensure smooth oil return of the compressor, but also avoid the phenomenon of liquid entrainment in the suction, and meet the requirements of operating a heat pump system with a wide ambient temperature.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a liquid storage tank, a compressor and an air conditioner. Background technique [0002] Under low temperature conditions, the air conditioning system is very prone to the phenomenon of compressor suction with liquid due to insufficient evaporation heat transfer, and even liquid shock in severe cases, causing damage to the compressor. In order to deal with this problem, a liquid storage tank is often added at the suction end of the compressor to separate the gas-liquid refrigerant, so that the gaseous refrigerant enters the compressor cylinder from the liquid storage tank through the connecting pipe, and the liquid refrigerant and lubricating oil accumulate in the storage liquid. At the bottom of the tank, there is a liquid return hole on the side wall of the connecting pipe at the bottom of the liquid storage tank. The mixture of liquid refrigerant and lubr...
