The Three Systems In An HVAC System

An HVAC system provides heating, ventilation, and air conditioning in buildings. HVAC systems are found in all kinds of places, from single family homes to high-rise apartment buildings, from schools to warehouses, and office buildings. This is a very important part of your facilities that requires the knowledge and skill set of HVAC technicians for installations, repairs and maintenance.

How does it work?

An HVAC system works to provide a comfortable environment for people inside any building structure. It controls temperature and humidity levels. It collects heat from the surrounding air using boilers or furnaces, then it will condition the air which goes through the ductwork throughout the building, after which it will be released into rooms through vents. The process then repeats itself over again as needed until the building temperature is at the desired level.

3 Main Systems That Make Up An HVAC System

HVAC system – the grouping of heating, air conditioning and ventilation systems. Clearly not a single system but rather a combination of different systems, each with its own characteristics. To work safely on an HVAC system, you must first understand the three main systems that make up an HVAC system. This article will discuss each one in detail.

The Heating System

The heating system in an HVAC provides heat to a building. Heating system has two main types, ASHP and GHP.

ASHP or air source heat pump warms your facility by using both air and electric resistance. It’s like an all-in-one unit with a furnace, a central air conditioner and a heat pump.

GHP or geothermal heat pump, also known as a ground-source heat pump, uses the earth as its source of heat energy. The HVAC system works by circulating water through buried pipes, then bringing it back up inside the building where it is warmed by the ground temperature before being circulated through your ductwork again.

The Ventilation System

The ventilation system in an HVAC system is the process by which air is transferred into and out of a building. It includes ductwork, fans and vents—all of which are controlled by a thermostat.

Ventilation is an important part of your HVAC system because it keeps the air inside your facility fresh and clean. When the air outside is polluted with dust, pollen or other pollutants, ventilation systems can help filter that air before it enters your home or office. Ventilation also improves indoor air quality by removing moisture from the air in the summer months and by keeping warmth inside during winter months.

The Air Conditioning System

The air conditioning in an HVAC system is the process of removing excess heat from an enclosed space by cooling it down to a comfortable temperature.

Air conditioners use refrigerants to absorb heat from the air and then release cold air back into the room. A gas form of a refrigerant is usually used in commercial buildings because it can handle larger amounts of heat than its liquid counterpart, due to its higher pressure at high temperatures.

An HVAC system can be difficult to repair if you don’t know how, because an HVAC has many components. Learn how the systems work before tackling a repair job, or better yet schedule an appointment with one of our technicians.
