Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a control component for refrigeration equipment. Background Art

[0002] The refrigeration principle of a general refrigerator is that the function of the compressor is to compress the steam with lower pressure into steam with higher pressure, so that the volume of the steam decreases and the pressure increases. The compressor inhales the working fluid steam with lower pressure from the evaporator, increases its pressure and then sends it to the condenser, where it condenses into a liquid with higher pressure. After being throttled by the throttle valve, it becomes a liquid with lower pressure and then is sent to the evaporator, where it absorbs heat and evaporates to become steam with lower pressure, which is then sent to the inlet of the compressor, thus completing the refrigeration cycle.

[0003] In the prior art, the throttling component in the refrigeration equipment usually adopts a throttling plate for throttling. Since the throttling plate is perpendicular to the water flow direction in the throttling tube, the resistance is large, the noise is increased, and it is not convenient to accurately control the flow of the throttling device. Therefore, we have introduced a control component for refrigeration equipment. Utility Model Content
