节流机构使制冷从高温高压液体进入蒸发器。
Throttle body made from high temperature and high pressure liquid into the evaporator of refrigeration.
其阀座的位置应保持淹没在波面以下，以防止高压气体冲进蒸发器。
The location of its seat should be kept submerged in the wave surface below to prevent high-pressure gas rushed into the evaporator.
高压气态制冷剂在冷凝器中向冷却介质放热被凝结为液态后，经节流装置减压降温进入蒸发器；
High pressure gas refrigerants in the condenser cooling medium heat to be setting for liquid, through the throttle device reduced pressure cooling into the evaporator;
高压液体经过过滤器、节流机构后喷入蒸发器，并在相应的低压下蒸发，吸取周围的热量。
High pressure fluid through the filter, the gush after the throttle body into the evaporator, and in the corresponding under low pressure, the quantity of heat of evaporation from around.
使用本装置，不仅可以有效控制蒸发压力，提高蒸发器的传热效率，同时可以控制高压侧的压力。
Using the mechanism can control the evaporation pressure effectively, raise the heat transferring efficiency of the evaporator and control the pressure in the high-pressure side.
