    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)
    the system consumes to have to occupy the
    building consumption total energy enormous
    partial proportions, approximately about 50%
    ~60%. Specially cold: East the unit, the cooling
    tower, the circulating water pump and the air
    conditioning unit, the new atmosphere unit, all摘要:空调基本上是一个没有绝缘盒的冰箱。它采用像氟利昂一样的制提供冷却。在冰箱和空调系统里氟里昂蒸发循环的机制是相同的。
    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
