Components of an HVAC Systems.

The heating, ventilation, and air conditioning systems are a significant part of any home or office. When you think about it, it is one of the most vital components in your home. Not only because it takes up a lot of space for the installation, but also because it plays a significant role in ensuring that you are comfortable. I know most people move into homes with HVAC systems and care less about them. However, if you do not have one in your home and want to install one like me, then you will need some insight. When I tried to install a Heating and Cooling system in my new home, I had to talk to some experts about it. I had some questions that bothered me:

  • How does heating, ventilation and cooling systems work?

After consulting a group of professionals in air conditioning, I came out with so much information that you should know. The systems comprise of many parts. They all work together to ensure that your air is always on point and you never have to struggle with cold rooms and stuffy enclosures.

How does it work?

The HVAC system has two sets of units in general. There is a unit placed inside the rooms and one placed outside. On the outside, you will get a fan, condenser, and refrigerant lines. On the other hand, the furnace, the vents, thermostat, vents, and the evaporator coil. All these constitute a functional AC unit in your home. Let’s talk about these parts in a little more detail:

Parts of the HVAC system

Thermostat

A thermostat is an electronically programmed unit that regulates the temperatures in your home. It is the one that provides an interface between you and the system. Usually, the thermostat is easily installed in your room and can be set manually or programmed. On the other hand, you can find a smart thermostat that regulates its temperatures based on your behavioral patterns. The thermostat works by triggering the system to heat or cool a room depending on the room’s temperature difference to your specified temperature.

Evaporator coil

From the laws of heat exchange, an evaporator coil draws heat from the environment and uses it to evaporate the refrigerant. Therefore, the evaporator coil works to lower the temperatures to the specified ambient temperature, according to your thermostat.

Condensing unit

This unit works on the same, but the opposite principle as the evaporator. Instead of taking the heat, it loses heat to the environment, to achieve cold temperatures for the refrigerant. The heat exchange takes place through copper tubes lined with aluminium fins to increase surface area for heat exchange. As a result, the condensing unit is used to heat rooms when the ambient temperature is below the specified ambient temperature.

The condensing unit, alongside the evaporator coil work to achieve the heating and cooling required in any room.

Furnace

keep your home warm by installing, repairing or maintaining furnaces in your home.

Usually, the heater is the most significant part of your system and requires the largest space. The furnace, as the name suggests, heats the air that then distributed through ducts. Depending on the type of HVAC system you have, the source of power for your furnace could vary. Some use solar energy, others electrical, while some use heat pumps and combustion.

Vents

This is the piping work used to deliver and collect air from a room. They are mostly in the ceiling, from where they distribute air. It is very crucial that nothing blocks these vents. Otherwise, you will end up in an uncomfortable environment in your own living space.

Refrigerant lines

These are the pipes that carry the refrigerant to the condensing unit as gas and take it back to the evaporator in the form of a liquid.

Types of HVAC systems

Before settling on a particular system to use in your home or office, you must understand the different types that are in the market. These include:

Heating and air conditioning split systems

This is the typical AC system, that has components in and out of your rooms. It comprises of an air conditioner for heating and cooling, ducts for distribution, a fan and a furnace. However, the new, improved models now have air purifiers, humidifiers, and air cleaners.

Humidity control

This is an HVAC system with a humidifier and dehumidifier unit. Therefore, with one of these systems, you can control the humidity levels in your home whenever the system is running.

Duct-free split system

This is a type of HVAC system that works without ducts. It is particularly favorable if you cannot build ductworks in your home.

Other types of HVAC systems include the zoned system that lets you cool and heats different parts of your home to different temperatures.
