并在其通过时被加热线圈（a）显著加热。这种加热空气具有更大的能力：
保持水分，并以与工艺空气相反的方向穿过干燥剂。当空气穿过
干燥剂它从车轮上吸收水分并干燥干燥剂。然后将再生空气吸入
风扇（C），并作为热/湿空气排出建筑物。车轮继续转动，重新激活
干燥剂准备再次处理空间。
系统变化：
1.干燥剂轮上的管道布置可能因装置而异。
2.干燥剂轮可在空气进入空气处理器之前对空气进行预处理，或调节正在通过的空气
空气处理器，取决于设计。
3.干燥剂单元不需要连接到空气处理器，它可以是独立的。

如果游泳池水位过低，管线将替换任何损失的水。
系统变化：
1.系统可以具有多组过滤器以去除不同水平的杂质。
2.加热线圈可能不存在于每个单元中。
3.加热盘管可能位于管道系统中较远的管线下方，称为再热。作为线圈的再加热

4.每个装置中可能不存在回风机。如果送风机产生足够的吸力，它会吸走空气

o the system and is heated significantly by a heating coil (A) as it passes. This heated air has a greater ability to
hold moisture and is pulled across the desiccant in the opposite direction of the process air. As the air crosses the
desiccant it picks up moisture from the wheel and dries the desiccant. The regeneration air is then drawn into
a fan (C) and exhausted out of the building as hot/humid air. The wheel continues to turn and the reactivated
desiccant is ready to treat the space again.
System Variations:
1. The arrangement of the ductwork on the desiccant wheel may vary from unit to unit.
2. A desiccant wheel may pretreat air before it enters an air handler or condition air that is passing through
an air handler, depending on design.
3. A desiccant unit does not need to be connected to an air handler, it can be stand-alone.
Evaporative Cooling System
Components/Layout:
Dampers
Filters
Heating Coil
Evaporative Media
Supply Fan
Return Fan
Air Flow:
This type of unit may be common in areas like Arizona and Nevada, where moisture removal from the air is not a
concern and where the moisture added to the air from this system helps to improve the low dew point. Starting
at the outside air intake, air enters the outside air duct and is mixed with return air from the space just before the
filters (B). The mixed air is pulled through a set of filters where impurities are removed. The air then passes over
a set of heating coils (C) where the air is heated to the required temperature if necessary. The air then passes
through the evaporative media (D). This media is a pad utilizing a honeycomb design that is saturated with cool
IPI’s Methodology for Implementing Sustainable Energy-Saving Strategies in Collections Environments (2017)
water. As the air passes over the media, water from the pad is evaporated into the air. This process removes
energy from the air resulting in a lower/cooler temperature, while at the same time adding moisture to the
passing air, increasing the dew point. Next, the air is pulled into the supply fan (E), which will push the air through
the supply ductwork, through the diffusers and into the space. The return fan (F) will then pull in air from the
space and push it through the return ductwork. Air is either exhausted or returned to the unit to be mixed with
outside air and start the cycle all over again.
Refrigerant/Coolant Cycle:
The heating coils are fed from a heat source such as a boiler or electricity. The heat from these coils is transferred
to the air passing over it.
The evaporative media is a pad made of a cellulose material that utilizes a honeycomb design. A supply system
adds water by pouring or dripping water onto the face of the media. This water cascades down the media and
what is not absorbed or evaporated to the air will collect in a special pool. Water from the pool is pumped back
up to the top of the media and reused. The pool is designed with a float to prevent overflow and a water supply
line will replace any lost water if the pool gets too low.
System Variations:
1. A system may have multiple sets of filters to remove different levels of impurities.
2. A heating coil may not be present in every unit.
3. A heating coil may be farther down the line in the ductwork in what is called a reheat. As a reheat the coil
will heat the air for a specific space just before it is discharged from the ducts.
4. A return fan may not be present in every unit. If the supply fan creates enough of a draw, it pulls the air
back through the space.
