五、膨胀装置专体充注气体充注的阀称为有限液体充注或最大作用压力(MOP)充注,因为感温包是用有限数量的相同制冷剂充注的,只要温包中存在有液体温度/压力关系,就总是适用的。在温包中的液体完全蒸发后,蒸气将作为气体而起作用,在温度增加时压力仅有轻微的增加。温包通常采用某一压力或温度下的蒸气充注,从而可以得到一个预定的截止点,在该点,制冷剂液体可以达到完全的蒸发。图9表示气体充注的热力膨胀阀的过热特性。该阀将以与液体充注阀相同的方式工作,
Fifth, the expansion device special filling gas filling valve called the limited liquid charge or maximum pressure (MOP) filling, because the temperature package is filled with a limited number of the same refrigerant, as long as the temperature package exists A liquid temperature / pressure relationship, it is always applicable. After the liquid in the warm pack is completely evaporated, the vapor will act as a gas, with only a slight increase in pressure as the temperature increases. Warm bags usually use a pressure or temperature of the vapor filling, which can be a predetermined cut-off point, at this point, the refrigerant liquid can reach full evaporation. Figure 9 shows the overheating characteristics of a gas filled thermal expansion valve. The valve will work in the same manner as the liquid fill valve,
