What Types of HVAC Systems Can You Choose From?
Since the birth of Heating, Ventilation, and Air Conditioning (HVAC) Systems, life has vastly improved. To the uninitiated, HVAC systems were made with the purpose of making indoor environments comfortable for humans and our hardware too. When looking around for the HVAC system that works for you, it may come as a bit of a surprise that there isn’t just one type. As development of better HVAC units are still ongoing, it can be a tad confusing then to figure out how the different types differ from each other. Let’s take a peek at some of the available types out in the market today.
Heating and Air Conditioning Split System
One of the more well known types of HVAC systems, a split system refers to when there is an indoor air handling unit as well as an outdoor condensing unit. Often used in residential and smaller commercial buildings—these are used solely for cooling. Albany HVAC is the local leader in this specific area.
The indoor air handling unit contains a fan, an expansion device, and a cooling coil. The outdoor condensing unit is comprised of a compressor and condenser oil. Throughout the establishment will be ducts to carry the air throughout the building. Split systems have been known to have the highest energy efficiency.
Hybrid Heat Dual Fuel System
This system makes use of the established strength of gas furnaces and electric heat pumps. Duel fuel systems make use of a heat pump for electricity fueled heating and cooling. This system will automatically pick the more economical fuel source (gas or electricity) based on the data gathered by its control panel.
This makes it quite easy for the user to take control of their energy consumption. The usual parts of this sort of system are a heat pump, a thermostat, furnaces and evaporator coils, and ducts. While hybrid systems are a tad bit more expensive than more traditional systems, but in the long run, the hybrid system has been known to cost the user less in terms of power consumption and maintenance costs.
Duct Free Heating and Air Conditioning System
The ductless HVAC system is a good choice for places where convectional systems cannot be installed. Ductless systems are built to deliver air directly into different zones of an establishment, building, or home. This system’s components are a small outdoor unit and one or several indoor units that only need to be mounted to access electricity. Ductless systems can also be tailored to fit buildings that already have a pre-existing systems installed.
Ductless systems run on less power than most other HVAC systems as they smaller and the temperature controlled air is funneled directly into a selected room or zone. This also means that an owner can select which rooms in their household or building can be considered a zone and which aren’t. Homeowners have taken a liking to ductless HVAC systems as they are relatively easy to install. For some homeowners, ductless HVAC systems are ideal as it allows for greater energy efficiency. When a system has improved efficiency, the less energy it uses. The less energy is used the lower the energy bill will be.
Ductless cooling and heating systems are established to be energy efficient and environmentally friendly.
Packaged Heating and Air Conditioning System
A packaged HVAC system is called that because the usual components (the evaporator, condenser, and compressor) are all placed in a single cabinet or otherwise “packaged” together. This sort of system is usually placed on the roof of a building. Packaged HVACs are mostly used by commercial spaces as they take up less space than other HVAC systems.
Installation costs are also lower than others as units are pre-packaged and merely need to be placed in an ideal spot. Users that want to save up on indoor space tend to choose a packaged HVAC system.
Central Air Conditioning and Heating
The original idea for central heating came from the Greeks. They distributed fire generated heat throughout their buildings through flues planted in the ground. Older versions of central heating made use of steam and hot water that was created through a boiler that’s usually located at the basement or at the back of an establishment.
This system is also known as “ducted air conditioning” this sort of system presents cooling or heating for whole-houses, larger commercial spaces, or establishments. Central heating is different from space heating as the heat generation happens in a single location such as a boiler or furnace room. The heat is circulated throughout a building through a series of ducts. In terms of energy efficiency, it may not be very great as heat or cooling goes to waste if only a single room is the recipient of it.
Free Cooling Systems
This particular system is highly efficient and often combined with seasonal thermal energy. The usual storage mediums for free cooling systems are deep aquifers and natural underground rock masses that’s accessed through a cluster of small to medium diameter boreholes.
Free Cooling is quite economical as it uses low external temperatures to chill water and funneled to lower the temperature of a home or a building. When the outside temperature drops, a modulating valve processes the chilled water and passes it through the free cooling system. This system makes use of very little power to much is saved in terms of utility bills.
The more common sources of natural cooling energy would be subterranean geothermal energy, high altitude coldness, deep sea or subterranean lakes or bodies of water, and the easily accessible cool night air.
As you can see, there are several HVAC systems to choose from. When it comes to picking the right one for you, it is best to consider where you want to HVAC to be, what sort of building you have, and finally what fits your budget. While each vary, they all inevitably help create a more comfortable environment for all.
