空气通过过滤器（A）进入装置。空气进入大型蒸发器盘管（B），在这里被冷却
并且线圈的温度非常低。如果通过的空气的露点高于盘管温度，
空气中的水分将冷凝并落到冷凝盘上。冷凝盘将允许水进入
以排出装置。冷空气被带到装置的后部，然后被向下推动，从那里通过
通过冷凝器盘管（E），用于在将空气从装置后部排出之前加热空气。
制冷剂/冷却剂循环：
该系统的工作原理就像一个基本的空调。就在膨胀阀（F）之后，制冷剂开始工作

现在是低温低压蒸汽。
制冷剂进入压缩机，在那里被加压成高温高压蒸汽。这个
制冷剂现在处于非常高的压力下并且具有高沸点。在这些条件下，制冷剂可以
容易浓缩。当制冷剂通过冷凝器盘管（E）时，装置内的风扇推动空气
穿过线圈。当风扇推动空气通过散热片时，制冷剂将热量排出到通过的空气中。这个
通过的空气将吸收热量，使制冷剂冷却并冷凝成液体。高压
液体流向冷凝器的出口，即膨胀阀。制冷剂将进入阀门
高温高压液体。该阀将允许制冷剂的压力变化
制冷剂将作为低温低压液体离开阀门，并重新开始该过程。

Air is brought into the unit through the filter (A). The air enters a large evaporator coil (B), here it is cooled
and the temperature of the coil is very low. If the passing air has a higher dew point than the coil temperature,
moisture in the air will condense and drop onto a condensation tray. The condensation tray will allow the water
to drain out of the unit. The cool air is brought to the back of the unit then pushed downward where it will pass
through a condenser coil (E) that is used to heat the air before ejecting it out the rear of the unit.
Refrigerant/Coolant Cycle:
The system works just like a basic air conditioner. Beginning just after the expansion valve (F) the refrigerant starts
off as a low temperature, low pressure liquid. Under this low pressure condition the refrigerant has a low boiling
point. The refrigerant is pushed through the evaporator coil (C) where it absorbs heat from the warm air that is
passing over the coils. The heat absorbed by the warm air causes the refrigerant to boil and become a vapor. The
refrigerant continues through the system toward the compressor (G). As it enters the compressor the refrigerant

is now a low temperature, low pressure vapor.
The refrigerant enters the compressor where it is pressurized into a high temperature, high pressure vapor. The
refrigerant is now under very high pressure and has a high boiling point. At these conditions, the refrigerant can
condense easily. As the refrigerant moves through the condenser coil (E) the fan inside the unit is pushing air
across the coils. The refrigerant will expel heat to the passing air as it is pushed though the fins by the fan. The
passing air will absorb the heat, causing the refrigerant to cool and condense into a liquid. The high-pressure
liquid moves towards the outlet of the condenser, the expansion valve. The refrigerant will enter the valve as
a high temperature, high pressure liquid. The valve will allow the pressure of the refrigerant to change and the
refrigerant will exit the valve as a low temperature, low pressure liquid and start the process over again.
