HVAC in full means heating, ventilation and air conditioning. HVAC systems have various functions including enabling fresh air into a room that dilutes the contaminated air, providing heated warm air into a cold room, providing cool fresh air into a room when required, etc.
HVAC systems are instrumental in homes, and for maximum results, they should be well designed to be efficient (reduces the cost of operation) and maintained adequately for more extended service. In choosing the type of system to put in your home, office, or any other place, it is a requirement that parameters such as air flow and pressure are calculated, and the area that the customer intends to use the system is revealed to the supplier. Choosing the right HVAC system increases efficiency and steadiness. Maintenance of the HVAC systems is done annually to avoid the system breakdown.
After assessing energy efficiency in the place that you want the HVAC system installed, and you want to choose a good system for your needs, then you can look at these four types of HVAC systems, namely; the Duct-free split system, the Packaged system, the Hybrid heat split system, and the Split system.
The latest systems provide a variety of options, including fan speeds and multiple speeds of heating and cooling.
This HVAC system has frameworks known as ‘split systems. The different parts are installed both inside and outside the room in question. The cooling unit will be used alongside a heater making it ideal for the heating and cooling services. The inner units of systems will comprise a fan an evaporator while the exterior piece a compressor, the fan, and a condenser. This type of system is quite efficient but is very expensive since the framework must fit inside and outside the required room.
This system uses both electricity and furnace heating technique. Here, since running of the furnace heating system as a single system is expensive, hence the necessity of having an electric heating system installed. Using the electrical system is cost saving and more efficient. The furnace system is mostly useable during the extreme cold seasons and electric system on reasonably cold days. This hybrid heat split system has characteristics similar to that of a split system as it must be installed both inside and outside the required room. Better yet, this system has an added advantage since it can be manually operated.
Most HVAC systems have vessels that are networked to spread heated or cooled air in the required room. There are a few that do not have these vessels, hence known as ‘duct-free. This system is considered to be very efficient since they depend on the heat pump and you can avoid losses that come from leakages and spoilt ducts. HVAC systems that use ducts sometimes are inefficient in places not convenient for the ducts such as garages or areas beyond the required building. Here the duct-free split system comes in handy. Also, since ducts are not used, they are more convenient when used in areas that require absolute cleanliness because there will be less dust and any other form of dust caused by the presence of ducts. Installation of the duct-free split system consumes less time and work. The only disadvantage of the system is that it requires more regular maintenance and changing of its components, which is demanding to the user.
When looking for an ideal system for a small home, a Packaged HVAC system is preferable since its components are installed outside the required room, hence saves a lot of space. When it comes to efficiency, this system is not as good as the other systems.
