How Many Types of HVAC Systems are There?

 

Introduction:

To begin with, HVAC stands for Heating, Ventilation, and Air Conditioning. This software is a collection of systems useful for a move between indoor and outdoor areas. Furthermore, it deals with both heating and cooling and is designed to improve ventilation in a building.

Types of HVAC Systems:

There are a few types of HVAC systems that are available for the heating and cooling needs of a home. However, choosing any one of them depends on factors like the location of the home, its existing ductwork, and its heating and cooling needs.

·      Split System- It has one unit inside the home and one outside and its setup consists of a furnace and air conditioner, an air handler and heat pump, or a furnace and heat pump.

·       Hybrid Heat Pump- It consists of an electric heat pump that works in conjunction with a furnace. It is also known as a dual-fuel system, and it costs less to heat the home with a heat pump than a furnace.

·  Ductless Mini-Split- It has an outdoor unit that contains the compressor and condenser. Furthermore, it consists of an indoor air handler responsible for blowing the cooled air directly into the room.

·     Ducted Mini-Split- This HVAC type uses tubes rather than larger ducts to move air into a room from an outdoor compressor. It has the advantage of better air circulation as compared to ductless mini-split systems.

·     Packaged System- It consists of all the traditional components of a split system. Furthermore, they are quieter and have lower installation costs. These are the best systems for homes that don’t have the space for a heating unit inside the home.

Components of HVAC:

Here are some of the most significant components of an HVAC System.

·   Design and the ductwork type- The ducts in the HVAC system should be of proper size and balance. These ducts ensure comfort and the externally insulated round ducts are best for this job.

·   Balance dampers in the ductwork- This component is useful in managing heating and cooling coming into a room. It is necessary to install it at some distance from the diffusers.

·    Location of the Indoor Unit- Some special design precautions are necessary to be taken while locating the indoor units. It is because locating them in the wrong place can cause leaks and ceiling damage.

·      Location of the Outdoor Unit- It is necessary to not place outdoor units in places where they can be seen and heard, or where they can be easily damaged.

·     Efficiency- 13-SEER is an ideal allowable efficiency that new air conditioners should have. The higher the SEER of AC, the lower is the utility bill.

·      The condenser (outside) coil type- Using single metal coils is usually beneficial as these coils last longer and hold their efficiency better.

·       Air Filter Location- This device needs to be replaced about every three to four months. Therefore, it is necessary to save them in a place where it is easy for the homeowner to reach them.

Understanding the Working of HVAC System:

HVAC systems aren't just limited to warming up or cooling the space. In addition, they also play a significant role in improving indoor air quality and providing comfort. All they require is a source of fresh air intake from the outside or from within the home. This process is known as natural ventilation and helps in exchanging the air to replenish oxygen. Furthermore, it helps in removing the signs of bad odors and carbon dioxide, and excessive moisture. HVAC facilitates Machinal ventilation which refers to the practice of moving air in and out. Due to this modern construction, homes are far more tightly sealed.

Therefore, mechanical ventilation is becoming a significantly important component in home HVAC systems. HVAC draws the air and sends it to an air handling unit where the work begins. This unit is responsible for removing dirt, dust, allergens, and other particles from the air. After that, it sends the air for either heating or cooling. Once the air is clean, fresh, and at a comfortable temperature, it directly goes toward homes. Many institutes provide HVAC Online Certification in Dubai and one can enroll in them to start a career in it.
