In this particular article, I am going to educate you on the Basics of HVAC System. To begin with, HVAC System is a Heating Ventilating and Air Conditioning unit. That is used to execute heating or cooling activities in both domestic and commercial facilities.

The goal of HVAC System is to enhance adequate inside/indoor air quality and thermal serenity. The basics of HVAC systems are important in helping you get a suitable HVAC system that bests suits your budget and health needs as well as your general needs. There are many HVAC systems in the market that include; Air Conditioners, Heat Pumps, Humidifiers, Ductless Systems, and Geothermal Systems among others.

Air conditioners come in various dimensions that include; general air conditioners, air conditioners plus air handler matched systems and air conditioner plus air handler matched system. Most of the air conditioners work similarly by being part of the central heating and cooling system. It takes away heat energy from the house and moves it to the outside air. As a result, it transforms the quality of air, humidity, and temperature and maintain air changes per hour in the area.

The air conditioner makes your environment cooler by taking the heat out of the house and moving it outdoors and changing the air in your environment with cooler air. The heat pumps also come in many dimensions that include; general heat pump, the heat pump plus air handler matched systems, and heat pump plus furnace matched system. The heat pumps majorly work by generating heat using electricity or gas.

They work efficiently by generating heat during cold seasons to a comfortable temperature range of between 30 to 25 degrees Fahrenheit. The humidifiers work by increasing humidity this is achieved by adding water vapor to the air. It operates using moisture sensors control that switches it on or off attached to a water panel that introduces water vapor to the circulated air as required.

A Ductless system employed in a house or building without a central cooling or heating system. The ductless system works using outdoor unit that is linked to an indoor unit using cables with a refrigerant line via a hole in the wall. The in house unit is usually mounted high on a wall and can be preset automatically or using a remote control to regulate the temperature as required. The Geothermal system moves a fluid via a coil to earth which takes away heat or produces heat a per the season.

During the cold season the system warms your premises by dissipating heat from the surface, and during the cold season, the system cools your home by absorbing heat from your home back the earth. The HVAC system validation works by deriving heat from the ground surface that’s usually constant and also taking back excess heat to the surface thus adjusting regulating your temperature as required. The geothermal system has various styles that include; Vertical loop, Open loop, Pond Loop and Horizontal loop as per the cleanroom design.

The vertical loop used when space is limited, whereby the heat transfer mediums are sunk down into the earth. The open loop uses groundwater as heat exchange media. The pond loop uses close to water sources for heat exchange. And the horizontal loop is used where there is plenty of space and the heat transfer equipment are shallow and extend outwards.
