Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] The core idea of ​​the present invention is that a regenerator is added to the refrigerating and air-conditioning system, and the liquid accumulator is removed. The feature of the added regenerator is that the regenerator can not only meet the heat recovery needs of the refrigeration and air-conditioning system, but also play the role of gas-liquid separation, liquid storage, and timely return of lubricating oil in the liquid receiver.

[0024] Such as figure 1 , figure 2 and image 3 As shown, a regenerator with gas-liquid separation function of the present invention includes a shell 02, an inner tube 03 and a baffle 04 arranged in the shell 02; the inner tube 03 penetrates from the bottom wall of the shell 02 , bent and distributed in the housing 02 and then pierced through the bottom wall of the housing 02; the baffle pl...

Abstract

A regenerator with gas-liquid separation function and a refrigeration and air-conditioning system using the regenerator, the regenerator includes a shell, an inner tube and a baffle arranged in the shell; the inner tube penetrates through the bottom wall of the shell, and The bending distribution in the housing passes through the bottom wall of the housing; the baffle is fixed in the housing and distributed between the bent inner tubes; the connection between the two ends of the inner tube and the bottom of the housing is respectively opened with a liquid inlet and a liquid Outlet, when in use, the liquid inlet is connected to the condenser, and the liquid outlet is connected to the throttle valve; there is an oil return hole at the junction of the baffle and the bottom wall of the shell, and an air inlet and an air outlet are opened on the side of the shell. When the air inlet is connected to the evaporator, the air outlet is connected to the compressor; the baffle divides the interior of the shell into multiple shells; the invention also discloses a refrigeration and air-conditioning system using the regenerator; the regenerator can both It meets the heat recovery needs of the refrigeration and air-conditioning system, and can also play the role of gas-liquid separation, liquid storage, and timely return of lubricating oil in the liquid receiver; in the refrigeration and air-conditioning system of the present invention, a regenerator is added, and the storage liquid container.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a regenerator with a gas-liquid separation function and a refrigeration and air-conditioning system using the regenerator. Background technique [0002] In the air conditioning and refrigeration system, in order to increase the cooling capacity of the system and ensure the normal operation of the system, a regenerator is sometimes installed. The regenerator enables heat exchange between the pre-throttled refrigerant (usually liquid) and the refrigerant from the evaporator (usually steam). As a result of the exchange, the subcooling degree of the refrigerant liquid increases, and the superheating degree of the steam increases, so that the temperature of the liquid before the throttling element of the system decreases, and the temperature of the airflow at the inlet of the compressor increases. For some refrigerants, such as R290 and R1270, using a system or cycle with a reg...
