HVAC – An Overview

Heating, air conditioning, and refrigeration are the main technology of vehicular and indoor environmental comfort. Its purpose is to offer acceptable indoor air quality and temperature for effective control of internal temperatures and for the comfort of occupants.

HVAC

A combination of mechanical and electronic systems are involved in its operation such as heat pump, distribution, and ventilating ductwork, heat exchangers, evaporative cooling fans, and many others. To provide an environmentally comfortable atmosphere, HVAC needs to be properly regulated through various mechanisms.

Fan, Air Conditioning, Turbine

The regulation of temperatures is done through heating and cooling systems that can be operated on individual control panels, in whole house controls or central thermostats. Heat pumps, ductwork and other air distribution devices are used to move air to various rooms of the house.

The rate of air movement and temperature is determined by the supply of air, the number of circulating fans, the speed of rotation of fans, and the condition of the supply air conditioning Bellevue Hill. The condition of the entire HVAC system is evaluated at periodic intervals to determine its performance and the need for repair and maintenance.

There are different types of HVACs available such as forced-air, ducted-heating, and liquid-imposition refrigeration. Forced-air systems work by supplying air through ducts into a specified area where heating and cooling systems are located. These systems are usually required for high-efficiency heating and cooling. Ducted-heating systems, such as chillers and small radiators, cool the interior of a room through convection.
