液管过滤器 liquid-line filter / liquid-line filter

制冷和空调系统的液态管路中用于去除和收集制冷剂中固体污染物的元件。

A component used in the liquid lines of refrigeration and air conditioning systems to remove and collect solid contaminants from the refrigerant.

液管干燥过滤器 liquid-line filter drier / liquid-line filter drier

制冷和空调系统的液态管路中用于去除和收集制冷剂中水分、酸和固体污染物的元件。

Components used in the liquid lines of refrigeration and air conditioning systems to remove and collect moisture, acid, and solid contaminants from the refrigerant.

平衡干燥点 equilibrium point dryness（EPD） / equilibrium point dryness (EPD)

在一定温度下，液管干燥过滤器吸收制冷剂中的水和制冷剂中所含水达到平衡状态，此时液态制冷 剂中含有的水量。EPD 是按质量计算，表示为百万分之几（10−6）。

At a given temperature, the liquid line filter-drier absorbs water from the refrigerant until it reaches an equilibrium state with the water contained in the refrigerant. At this point, the water content present in the liquid refrigerant is defined as the EPD (Equilibrium Point Dew). EPD is calculated by mass and expressed in parts per million (10⁻⁶).

压降 pressure drop / pressure drop

液态制冷剂流过被测过滤器进出口（含连接件）间的压力差，单位为千帕（kPa）。

The pressure difference between the inlet and outlet of the tested filter (including connectors) when liquid refrigerant flows through it, expressed in kilopascals (kPa).

制冷剂流量 refrigerant flow capacity / refrigerant flow capacity

液态制冷剂单位时间内流过压差一定的过滤器时的质量，制冷剂流量在43℃条件下测定，单位为 千克每秒（kg/s）。

The mass of liquid refrigerant flowing through a filter with a certain pressure difference per unit time, measured at 43°C, is expressed in kilograms per second (kg/s).

容量 refrigeration capacity / refrigeration capacity

液态制冷剂单位时间内的制冷量，单位为千瓦（kW）。

The cooling capacity of liquid refrigerant per unit time, expressed in kilowatts (kW).

吸水量 water capacity / water capacity

在给定的温度和EPD 条件下，过滤器与液态制冷剂充分接触达到平衡后，吸收和保持的水量，单 位为克（g）或滴（20 滴相当于1 g）。 国标久久 www.gb99.cn 免费下载 JB/T 11213—2011 2

Under specified temperature and EPD conditions, after the filter fully contacts the liquid refrigerant and reaches equilibrium, the amount of water absorbed and retained, expressed in grams (g) or drops (20 drops equivalent to 1 g).
