Problems solved by technology

However, the disadvantage of this liquid separator is that there is still no vapor-liquid two-phase mixing chamber, and the mixing of vapor and liquid is not sufficient. In addition, the manufacturing process of the Venturi liquid separator is complicated. For refrigeration systems with large cooling capacity, its The volume is too large, the cost is too high, and it is rarely used in practice

Abstract

The invention discloses a low-pressure drop, fully uniform-flow distributor for air source heat pumps, which can sufficiently mix the vapor phase with the liquid phase and uniformly distribute vapor and liquid. The distributor comprises a top distributor cap (1) and a distributor base (2), the distributor base (2) is provided with a vapor-liquid refrigerant inlet (5) and a plurality of vapor-liquid uniform distribution sockets (4), the top distributor cap (1) is hermetically connected with the distributor base (2), a vapor-liquid mixing chamber (3) is formed between the top distributor cap (1) and the distributor base (2), the vapor-liquid refrigerant inlet (5) is communicated with both the vapor-liquid uniform distribution sockets (4) and the vapor-liquid mixing chamber (3), and a cone (6) is arranged on the top distributor cap (1), and is extended into the vapor-liquid refrigerant inlet (5). The invention can be widely applied in air source heat pump heating / refrigerating systems.

Description

technical field [0001] The invention relates to an air source heat pump low-pressure drop completely equal flow separator. Background technique [0002] Among the components used in the refrigeration industry, the liquid separator is one of the important components. It plays a key role in the evaporation efficiency of the finned evaporator. For air source heat pumps and direct evaporative refrigeration units with refrigerant to air, the liquid separator is An indispensable and important part. Its working principle is: in the refrigeration system, the refrigerant flows from the condenser to the evaporator and passes through the expansion valve to decompress and throttle, part of the refrigerant flashes, and changes from liquid to vapor. Therefore, the state of the refrigerant after passing through the expansion valve is a low-pressure, low-temperature vapor. , Liquid two-phase refrigerant, the liquid distribution system consists of a liquid separator and capillary copper tub...
