Document Type and Number:
WIPO Patent Application WO/2020/107798
Kind Code:
A1
Abstract:
Disclosed is a liquid storage tank applied to a compressor. The liquid storage tank comprises a shell (1) with an air inlet pipe (2) and an air outlet pipe (3), wherein the air outlet pipe (3) comprises an extending section (31), and the extending section (31) extends into the shell (1); and the liquid storage tank further comprises a separator (4) used for separating out a liquid refrigerant, and a sleeve (32), wherein the separator (4) is arranged between the air inlet pipe (2) and the extending section (31), the sleeve (32) is sleeved on the outside of the extending section (31), the end of the sleeve (32) that is away from the separator (4) is closed, the end of the sleeve that is close to the separator (4) is used for receiving the liquid refrigerant separated out by the separator (4), a first liquid storage space (61) is formed between the sleeve (32) and the extending section (31), an oil return hole (310) is formed in a pipe wall of the extending section (31), and the oil return hole (310) communicates with the first liquid storage space (61). The liquid storage tank applied to the compressor can ensure the flow power of the liquid refrigerant and a lubricating oil mixture, regardless of whether same is under a high-temperature working condition with less refrigerant or a low-temperature working condition with more refrigerant, the oil return amount remains stable, and requirements of a heat pump system running across a wide range of ambient temperatures are met.
