Types Of Hvac Systems

There exist several types of HVAC systems that can be used by the consumers in accordance with their needs and comfort. This should be planned and carried out in such a way that it does not unnecessarily lead to the use of excess power or cause an increase in the cost of living. In other words, HVAC systems should be used in a power efficient and cost effective manner. Listed below are the kinds of HVAC systems that exist, and the kinds of climatic or situational conditions that they are best suited to:

Single Stage System:

HVAC systems providing only heating or cooling services, which tend to be inexpensive under ordinary circumstances, are referred to as Single Stage Systems. These are ideal for people living in extreme climatic conditions of heat or cold. However, it must be kept in mind that these HVAC systems do not tend to be very efficient, and are therefore ideal for small-scale or household purposes only.

Multi-Stage System

The majority of today’s heating and cooling systems have several stages to warm or cool air.  Instead of relying on a single stage to generate extremely hot or cold air, multistage systems operate at different levels to create a comfortable environment. This is why they are referred to as multistage systems. Instead of applying the same amount of hot or cold air to the area, multistage systems deliver the air according to the unique conditions that are present during each season of the year. This way, the system provides an adequate amount of warm or cool air to make one more comfortable, save money on energy bills and also help the environment. Multi-stage systems are thus far more cost effective and power efficient than their single state counterparts and are now preferred more in all sectors.

Zoned System:

Zoned systems are yet another means of saving on power and electricity bills. Usually ideal for owners of large properties, parts of which do not have equal requirements of heating or cooling. In case of a Zoned system, valves and dampers are introduced inside the ducts in order to selectively block the flow of air. Consequently, air is vented out at only those areas where it is most needed. Thus, Zoned systems can be employed in Hospitals or Shopping Malls which require varying degrees of thermal comfort, depending on the needs and circumstances. For instance, food courts would require much less cooling than enclosed Restaurant areas and the Restrooms would require much less cooling than any. Thus, Zoned systems have been designed to cater to the needs of individual units or spaces inside the buildings they are used in.

Humidifiers/ Dehumidifiers

HVAC systems may be devised and designed to provide for the function of Humidity control. Both humidifiers and dehumidifiers may be added to the heating or cooling system in accordance with the needs of the people. In case of extremely dry conditions or in the tropics, this is considered to be one of the most essential units of the HVAC.
