What You Need To Know About Different HVAC Systems Types

Heating Ventilation, air conditioning, and cooling system (HVAC) is a system that works on the principles of the refrigeration cycle in which a liquid known as refrigerant helps to transfer heat to the atmosphere to cool down the intended house or office.

Following are four main types of HVAC systems that you need to consider when installing. These four systems are.

  • Split System
  • Hybrid System
  • Duct-free system
  • Packaged heating and air system

Residential HVAC System:

Residential HVAC System

You can use HVAC systems for your home and small apartments, which are rather small compared to their commercial counterparts.

Therefore, residential systems are mostly mini-split systems that have an indoor unit, the AC and an outdoor unit, the condenser, which can be installed in each room having a residential HVAC control system.

The outdoor units provide easy access for the technicians to maintain the system periodically and, therefore, install it.

If the maintenance is complicated, basic maintenance can be done by the homeowner himself.

Commercial HVAC System:

Commercial HVAC Systems

A commercial HVAC system, in theory, is the same as any HVAC system, but the scale is big when compared to a residential system in both size and complexity.

Commercial systems are manufactured differently, too, as commercial ones are designed to keep modulation in mind, allowing easy maintenance access.

Therefore, most parts of commercial HVAC are placed on rooftops for open space and ease of access.

Primarily these systems are housed in a single cabinet which is why these are known as packaged units.

Commercial HVAC systems consume more power and energy as they are required to supply heating and cooling to a much larger area while providing more than one thermostat for temperature control for different zones.

HVAC Split System:

HVAC Split System

While the packaged system contains all the components of the HVAC system in a single shell (the most common example being a portable chiller that looks like a refrigerator).

Split HVAC systems primarily have an indoor AC or a blower while the second component resides as an outdoor unit used as a condenser to transfer heat to the atmosphere via a blower.

Because of two separate systems, the Split system is energy-efficient, having the SEER ratings well above 25 and easier to maintain, which hardly needs opening the circuitry and can easily be cleaned by yourself.

HVAC System Components:

HVAC System Components

Following are the components of when building HVAC systems:

Heat Exchanger/Condensor – The outdoor unit that has looping pipes in such a way that it increases the surface area of the unit, giving it more time to exchange heat by the blower through air convection.

Air Conditioner – It is the component that works as an air cleaner or humidifier and helps to remove heat by air convection.

Compressor – This is the main component of the cooling cycle.

It pushes the refrigerant around at higher pressure and raises the temperature.

So it helps the air conditioner to cool faster and more efficiently.

Because the refrigerant goes to the condenser directly from the compressor to exchange heat with the atmosphere.

Evaporator Coil – This works under the principle that if the refrigerant is expanded quickly.

It cools down rapidly, which allows the HVAC indoor unit to absorb heat from your home and cool it in the process.

This process becomes faster by the blower in your AC, making air convection faster.

Thermostat – Modern residential HVAC system comes with a thermostat that has a temperature sensor and temperature degree control unit.

It will detect when your room has reached the threshold so that it needs to turn on the compressor for faster delivery of the compressed gas for more expansion near the AC and faster cooling.

Automatic temperature control can help you save money and keep your indoors cool longer.

Best HVAC System:

Best HVAC System

When choosing the best HVAC System for your home or office, the following are some essential points that you need to consider:

Comfort Temperature and Air Quality – Using UV with your AC systems can help to enhance the quality of air inside your home as it can help you identify the air inside your house.

Efficiency – Consult SEER and other codes to know the best and efficient HVAC system.

Capacity – A single 1 Ton AC is perfect for a 2-3 room house while 2 Ton AC for halls and increasing further for offices and factories. Consider the numbers when deciding.

Maintenance and Installation Cost – Initial cost and periodic maintenance cost highly depend on your budget.

You don’t want to pay more on a system that will still be costly with each periodic maintenance. Always consider your pocket before buying.
