All About HVAC Systems

From the simple air conditioning units that cool homes to the robust systems that can manage industrial complexes, HVAC systems ensure proper temperature control and comfort through their use. By taking advantage of thermodynamics, fluid power, and heat transfer, HVAC systems can either heat or cool buildings and regulate humidity as needed. With varying types of HVAC systems being available on the market, it can be useful to be aware of the roles and functionalities of each to make a more well-informed purchasing decision.

For areas that are often subject to colder temperatures, heating systems can prove crucial for safety and comfort. Heating systems come in a variety of forms, one example being furnaces that burn natural gas or propane in order to create heated air that can be transferred through the use of ductwork. With boilers, a similar process can be conducted, albeit with heated water to create steam. Forced-water systems are also beneficial for heating, and they utilize heat pumps, electric heat, and radiators for their temperature control.

For more industrial or commercial settings, hydronic heating systems can be useful. With such assemblies, piping is placed under a floor and contains either a glycol solution or water that may be heated. Due to their method of temperature control, hydronic heating systems can be placed beneath wood, tile, concrete, or any type of floor in a building. For wooden floors, such systems require installation in sheathing.

For cooling systems, on the other hand, devices such as air conditioners prove to be the most widely used types. With a variety of shapes, sizes, and installation methods available, air conditioners can be a fixture or a portable device that can be pulled out when not needed. With portable air conditioning devices, the owner can install the system themselves and ensure that all interior and exterior components are attached. Due to their lower price point as compared to other types, portable systems prove quite popular for many.

When there is a need for more humidity, such as in drier climates, evaporative coolers are very desirable. With such systems, air is drawn from the outside atmosphere and forced through water-saturated pads. This causes the air to both cool down and increase in moisture content, allowing for a room to displace hot air for wetter and cooler air.

Depending on the types of devices that are used for treating air, a number of layouts may be present. In many buildings, cooling can be provided by an air handling unit that filters and cools outside air and passes it through a fan and coils before it reaches a ventilated room. As another method, a chiller can provide cool air to the coils through a pump, and then a cooling tower is used to expel heat. For heating, boilers are very common, and a pump is used to transfer heat through the coils to the ventilated room. With all HVAC systems in such a set-up, air is always forced through a set of coils before passing into the room so that it either be heated or cooled.

With a proper HVAC set-up in place, air can be treated to heat or cool rooms as needed for the safety and comfort of all within.
