这些装置类似于标准的壁挂式装置，通常是许多酒店客房使用的装置。预处理
空气从主空气处理系统（F）供应至装置。空气与来自以下空间的其他空气混合：
通过装置底部的阻尼器（E）引入。混合空气通过风扇（D）被推入
加热盘管（B）和冷却盘管（C），必要时在其中处理空气。冷却盘管的典型功能是：
明智地冷却经过的空气。该装置几乎不进行除湿。然后，空调空气
将装置顶部推入空间。这些装置通常没有安装任何形式的加湿装置
在他们身上。
制冷剂/供暖供应：
冷却盘管由冷却源（冷却器、冷却塔、DX装置）供应。制冷剂进入
吸收热量并从通过的空气中除去水分的线圈。制冷剂返回其冷却源以：
解吸吸收的热量。

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

hese units are similar to the standard wall mounted unit and are typically what many hotel rooms use. Pretreated
air is supplied to the unit from a main air handling system (F). The air is mixed with other air from the space that
is pulled in through dampers (E) at the bottom of the unit. This mixed air is pushed through the fan (D) into the
heating (B) and cooling coils (C) where the air is treated if necessary. The typical function of the cooling coil is to
sensibly cool the passing air. Little to no dehumidification is performed by this unit. The conditioned air is then
pushed out the top of the unit into the space. These units typically do not have any form of humidification installed
on them.
Refrigerant/Heating Supply:
The cooling coils are fed from a source of cooling (chillers, cooling tower, DX unit). The refrigerant enters the
coils which absorb heat and remove moisture from the passing air. The refrigerant returns to its cooling source to
desorb the heat that it has taken in.
IPI’s Methodology for Implementing Sustainable Energy-Saving Strategies in Collections Environments (2017)
The heating coils are fed from a heat source (boiler, electricity). The heat from these coils is transferred to the air
passing through it.
System Variations:
1. The arrangement of the cooling coil and heating coil may vary from unit to unit.
2. A cooling coil may not be present in every unit.
3. A heating coil may not be present in every unit.
4. A unit may not always be oriented vertically.
5. A unit may be installed on a wall or ceiling.
6. A unit may have a set of filters installed before the fan.

Air Flow:
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 refri
