Heating, ventilating, and air conditioning (HVAC) of buildings is accomplished in many ways, depending on the size, configuration, and location of the buildings and the degree of environmental control
Fuel consumers face a double challenge. One is economic – to get the best heating value for every fuel dollar. The other is environmental – to keep emissions low, at least within legislated limits. Fo
Commercial air conditioning may be provided by a variety of equipment ranging from low horsepower self-contained systems to the very large built-up central systems of several thousand ton capacity. Cu
Successful HVAC systems are the key to successful buildings. In a central system, air can be conditioned in a remote location in the air-handling units and distributed to the various rooms by ductwork
The three primary reasons that the cooling water treatment may be required are to control corrosion, scale formation, and the growth of biological agents. Any of these problems – or more usually a com
In large commercial and industrial systems, chilled water system serves as means to transfer heat from building spaces to the refrigeration system. Initially, when energy costs were low, constant volu
Ventilation (the V in HVAC) is the process by which clean air (normally outdoor air) is intentionally provided to a space and the stale, overheated or polluted air is removed. Ventilation includes bot
Most HVAC systems are designed to handle the maximum potential temperature extremes, keeping the building cool on the hottest days and warm on the coldest days. As a result, the HVAC system only needs
