Problems solved by technology

However, due to factors such as fan air volume, environmental conditions, and compressor speed, the refrigerant flow rate through the split hole changes.
Obviously, it is difficult for the splitter plate to adapt to the refrigerant distribution requirements under variable flow conditions

Abstract

The invention discloses an air conditioner. A heat exchanger applied to a heat exchanging loop comprises flat pipes and a distributor. The distributor is used for distributing a gas-liquid two-phase refrigerant uniformly to multiple flat pipes. A flow jetting cavity and a backflow cavity are formed in the distributor. The refrigerant in the refrigerating pipeline is jetted into the flow jetting cavity and accelerates and flows, and dispersed bubble flow is formed. The refrigerant in the flow jetting cavity is jetted into the flat pipes, and the refrigerant, which is not jetted into the flat pipes, in the flow jetting cavity flows back to the backflow cavity and flows back to the flow jetting cavity and enters next flowing circulation. By means of the distributor, it can be achieved that under variable working conditions, the two-phase refrigerant is distributed uniformly inside different flat pipes in the same process, the heat exchanging effect of the heat exchanger is improved, and then the integral heat exchanging effect of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an air conditioner with uniform flow distribution of refrigerant. Background technique [0002] At present, the heat pump type air conditioner is a kind of heating and cooling air conditioner that is often used. When cooling in summer, the air conditioner cools indoors and dissipates heat outdoors; while heating in winter, the direction is opposite to that in summer, that is, heating indoors and cooling outdoors. The air conditioner exchanges heat and cold between different environments through a heat pump. For example, in winter, outdoor air, surface water, groundwater, etc. are low-temperature heat sources, while indoor air is a high-temperature heat source. The function of heat pump air conditioning is to transfer heat from the outdoor environment to the indoor environment. [0003] refer to figure 1 As shown, a schematic diagram of a heating cycle of a heat...
