Refrigeration system and liquid dispenser thereof

Abstract

The invention discloses a refrigeration system and a liquid dispenser thereof. The liquid dispenser comprises an inner pipe, a middle pipe and an outer pipe, wherein the chamber of the inner pipe comprises a first gradually-reducing part which is gradually reduced along the cross section from a first end to a second end of the inner pipe; a first interlayer chamber is formed between the inner wall of the middle pipe and the outer wall of the inner pipe; the first interlayer chamber comprises a second gradually-reducing part which is gradually reduced along the cross section from the first end to the second end of the first interlayer chamber; the inner pipe is provided with a liquid dispensing hole so that a refrigerant mixed through the first gradually-reducing part can enter the second gradually-reducing part via the liquid dispensing hole; the outer pipe sleeves the outer layer of the middle pipe; a second interlayer chamber is formed between the inner wall of the outer pipe and the outer wall of the middle pipe; the first end of the outer pipe is connected to the outer wall of the inner pipe through a bending plate; a liquid dispensing tray is connected between the second end of the outer pipe and the outer wall of the middle pipe. Due to the arrangement, the liquid dispenser of the refrigeration system disclosed by the invention is capable of improving the gas and liquid mixing uniformity of the liquid dispenser so as to guarantee the uniformity of the refrigerant which is dispensed into an evaporator.

Description

technical field [0001] The invention relates to the technical field of refrigeration, and more specifically, to a refrigeration system and a liquid separator thereof. Background technique [0002] In the refrigeration system, after the refrigerant passes through the throttling device, it becomes a gas-liquid two-phase state and flows into the evaporator. Whether the refrigerant can be evenly distributed to each branch of the evaporator has a crucial impact on the performance of the evaporator and even the entire refrigeration system. The liquid separator is an important auxiliary device, which is used before the evaporator to evenly distribute the gas-liquid two-phase refrigerant to each branch of the evaporator. [0003] The type of liquid separator commonly used in the market is Venturi liquid separator. Its main principle is: after the refrigerant passes through the shrinking and expanding nozzle, the flow rate increases, and the gas-liquid two-phase is mixed evenly, so ...

AI Technical Summary

Problems solved by technology

But it has a disadvantage: the flow of refrigerant in the Venturi liquid separator often causes uneven mixing of liquid and vapor under alternating operating conditions, resulting in uneven final distribution
