We all need comfort in our life. This is why we always try to choose a gadget, which can give us perfect comfort like providing a hot environment in winter and a cool temperature in summer. In this process, the HVAC system can help you. But do you know what HVAC is? If not, let’s figure it out.

What is an HVAC System

What Is An HVAC System?

HVAC refers to Heating, Ventilation, and Air Conditioning. This is a system that allows residential and commercial buildings to become hot or cool. It also takes care of Indoor Air Quality or IAQ. This system is an amalgamation of many types of equipment, which are placed together and provide hot air in winter and cold air in summer. Also, it controls the indoor climate and gives comfort.

This system works on the theory of thermodynamics, fluid mechanics, and heat transfer. By HVAC, we are able to remove moisture, smoke, dust, odors, carbon dioxide, etc., from the air. After removing those harmful things, HVAC helps us to convert them into oxigen. Now, this has become more popular, and it gives us comfort. It has become a basic need for homes, industries, vehicles, buildings, aquariums, and many other mediums. 

Nowadays, HVAC water chillers have become a popular thing that industries mostly use for their various needs. This system includes some products like air conditioners. Most of us have air conditioners, and damages are common. If you want an expert guide for this, you can consult the top companies for AC repair in La Mesa.

Basic Components of HVAC System

HVAC system consists of basic components like:

  • Air Conditioner
  • HVAC water chillers and heaters
  • Chilled water pumps
  • Hot water generator or furnace
  • Cooling water pumps
  • Cooling towers
  • Electrical power supply control
  • Valves for chilled water and cooling waterslides
  • Heating coils and cooling coils
  • Ducts in the ventilation system
  • Air handling units

How Does The HVAC System Work?

Your HVAC system is the main source of heating and cooling a room or office. With a high-quality and intact system, you always feel comfortable in the peak winters or the heights of summer at your home or commercial premises. So, how does this core system of heating and cooling work? Let’s watch out.

Heating and Cooling Distribution Systems

When we want to know about the mechanism of HVAC, we need to know details about how the distribution of heat or cold in a room or a stadium happens.

Forced Air Systems

A forced-air system is a process where the hot air or the cold air is forced by the system through metal ducts using a blower. Hot air and cold air travel into different sets of ducts during the heating and cooling process. However, it’s up to you which machine you use, the best air conditioner or the furnace. But users face a problem of blowouts. It can break down or face issues towards the end of its lifespan. When it malfunctions, get your HVAC repaired from the top AC Repair professionals in La Mesa.

Gravity Systems

It is another system based on the gravity principle in which when hot air rises, cold air would sink and vice versa. The position of this system is in the basement. When we switch on the machine, the warm air rises through the ceiling and you enjoy hot air in the house during the chilled winter. When this air cools down, it sinks to reheat again. Thus, you enjoy a hot climate all through the winter with zero inconveniences.

Radiant Systems

Through this system, we are able to heat our room’s floor, ceiling, or walls. But it has a problem that you can’t use it for air conditioning. It actually heats the radiators, and it distributes heat towards our room.

List of HVAC System Components and How They Work

HVAC systems have many parts, but they have six main components on which the whole system is controlled.

Thermostat

The thermostat is like the heart of an HVAC system. However, it is the most interactive part of it. You can place it on the wall. It helps to control temperature. When the air becomes too hot or too cool, it starts working and gives a room of comfortable temperature.

Furnace

It heats the air using natural gas or oil. However, the heat exchanger is responsible for heating air to the temperature you set and providing comfort and a cozy environment. Usually, a furnace is in the basement, attic, or any closed space. 

Evaporator coil

When the thermostat is set at a lower temperature, the evaporator coil or the evaporator core holds the chilled refrigerant to cool the air indoors and distribute it.

Condensing unit

Condensing unit is installed outside of the house that either releases or collects hot air. It has various tubes filled with refrigerant gas. When the gas becomes cool, this unit pumps this liquid to the evaporator coil to transform it into a gas again.

Vents

It is a part that helps to distribute hot or cool air throughout the house. Vent installation is near the ceiling. You have to be careful that it doesn’t block.

Refrigerant lines

The refrigerant line helps to carry refrigerant in the form of gas to the condensing unit.

Who has the Control of Heating and Cooling Systems?

The thermostat and bimetallic elements are the main part to control the heating and cooling system. The former helps to set the temperature as per your preference. On the other hand, the latter ones expand or contract based on the change in the temperature of your room.

Conclusion:

HVAC is not a tricky system, and if you understand, it benefits you a lot. They are of different types like Heating and air conditioning split system, Duct-free split system, Zoned systems, Humidity control, etc. To know about how it works and take it into your house.
