s to condense. As the refrigerant continues its journey through the condenser it continues to condense and, ideally, the refrigerant will turn fully into a liquid by the time it exits the condenser. From the condenser, the liquid refrigerant travels onto the modulator. This looks like an extra tube welded onto the side of the condenser. The modulator performs three main actions. One, it acts as a filter, filtering out particles as they travel around the AC system. Second, it acts as a dryer. The dryer in the modulator contains desiccant (like the silica gel you find in a new box of shoes). This desiccant absorbs water. As water gets into the system the dryer tries to remove it. The third function of the modulator is a reservoir. Bearing in mind the pressure and temperature of the refrigerant inside the AC system regularly changes, so does the refrigerant’s volume. This varying volume is accommodated by the receiver dryer.
由于制冷剂中的热量被去除当热量从制冷剂中剔除，制冷剂开始液化。当制冷剂继续穿过冷凝器时，它不断液化，。理想状态下正常情况下，当制冷剂离开冷凝器时，它会完全转变为液态。液态冷凝剂接着从冷凝器向调节器移动。调节器看起来像是焊接到冷凝器一端的一条附加管道。它主要有三个功能：首先，它像是一个过滤器，颗粒在穿过AC系统时会被过滤出来。第二个作用是，它像一个干燥器。调节器里的干燥器装着干燥剂，貌似新鞋鞋盒中的硅胶。干燥剂会吸收水分，所以当水分穿过系统时，干燥剂会将水分吸收掉。调节器的第三个功能是一个储存器装置。在AC系统中循环的制冷剂的压强和温度是有规律变化的，制冷剂的剂量也是如此。变化的剂量储存在接受者角色的干燥剂储液干燥器中。中。
From the modulator, the refrigerant flows towards the thermal expansion valve. This is a self regulating valve which controls the amount of refrigerant able to pass into another heat exchanger located by the heater matrix called the evaporator. As liquid refrigerant passes through the expansion valve, into the low pressure side of the circuit, a pressure reduction occurs. This pressure reduction causes the liquid refrigerant to be on the verge of becoming a gas but it is still a liquid at this specific point.
制冷剂从调节器中出来，流向热膨胀阀。这个阀是一个自动调节阀，控制可以通过的制冷剂剂量。制冷剂通过后将流入另一个换热器。这是由称为蒸发器的加热器矩阵所固定的一个换热器。液态制冷剂通过膨胀阀，进入环路的低压端时，压强减小。压强的减小使得液态制冷剂几乎变成气态，但在通过膨胀阀这一刻，它的状态仍是液态。
If you increase the pressure applied to a gas you eventually end up with a liquid; inversely, if you reduce the pressure applied to a liquid you will eventually end up with a gas. It is only when the liquid travels into the evaporator that the liquid evaporates and becomes a gas. This process occurs due to the refrigerant absorbing heat from the air being blown through the evaporator. The process of evaporation causes a cooling effect. The larger the quantity of liquid travelling into the evaporator, the more evaporation that will occur, which in turn will lead to a higher quantity of heat energy being absorbed by the process.
如果你增大施加在气体上的压强，最终它会变成液态。反过来，如果减小施加在液体上的压强，它会变成气态。只有在液态制冷剂穿过蒸发器时，液体蒸发，变成气态。发生这一过程的原因是制冷剂从经过蒸发器的空气中吸收了热量。蒸发的过程产生了制冷效应。经过蒸发器的液体量越多，就会发生越多的蒸发过程。其结果就是在这一蒸发过程中，被吸收的热量也就越多。
