split-system and a window air conditioner.
In warehouses, businesses, malls, large
department stores, etc., the condensing unit
normally lives on the roof and can be quite
massive. Alternatively, there may be many
smaller units on the roof, each attached inside
to a small air handler that cools a specific zone
in the building.
Let's take a look now at a chilled-water air
conditioner.
Chilled-water System
In larger buildings and particularly in
multi-story buildings, the split-system approach
begins to run into problems. Either running the
pipe between the condenser and the air handler
exceeds distance limitations (runs that are too
long start to cause lubrication difficulties in the
compressor), or the amount of duct -work and
the length of ducts become unmanageable. At
this point, it is time to think about a
chilled-water system.
In a chilled-water system, the entire air
conditioner lives on the roof or behind the
building. It cools water to between 40 and 45 F
(4.4 and 7.2 C). This chilled water is then piped
throughout the building and connected to air
handlers as needed. There is no practical limit
to the length of a chilled-water pipe if the
system can be got well - insulated.
Whenever you walk behind a building and
find a unit that has large quantities of water
running through a plastic mesh, you will know
you have found a cooling tower!
In many office complexes and college
campuses, cooling towers and air conditioning
equipment are centralized, and chilled water is
routed to all of the buildings through miles of
underground pipes.
The energy conservation may say is the
building character automatic control system
starting point and the home to return to. It is
well known, in the intelligent construction,
HVAC (heating, ventilates and air conditioning)

partial proportions, approximately about 50%
~60%. Specially cold: East the unit, the cooling

节能可以说是楼字自控系统的出发点和最后归宿。众所周知，在智能建筑，HVAC（加热，通风和空调）系统消耗不得不占用该建筑物消耗的总能量巨大部分的比例，约50% ~ 60%。特别是东部寒冷地区的冷却塔，循环水泵和空调机组，新风机组，都是耗能大户。因此，确有必要的发展的一种有效的空调系统节能方法，特别是使用在提高现有建筑物的空调系统自动化方面。
当外界温度开始上升，很多人追求室内空调的凉爽舒适。像冷却水塔和电源线，空调都是那些我们每天看到的却很少重视的一个。那知道这些不可缺少的机器是如何工作的魔术岂不是很高兴？在这篇文章中，我们将研究空调 - 从小型到巨大的 - 让你更了解你所看到的！论文网
