Today there are many different types of HVAC systems. They come in all different sizes and all come at a different cost. Always keep in mind that cheaper isn’t always the better choice. When you are looking to purchase a new HVAC system it is important that you are environmentally conscious. There are many different types of HVAC systems that are harmful to the environment just as there are many that are safe for the environment. It is no longer important to just make sure that your needs are satisfied and your HVAC system is safe for your home you also need to take into consideration the earth. Certain things HVAC systems put off are harmful to our earth and killing the ozone layer. There are however two types of air condition systems that are environmentally safe that you should keep in mind when purchasing a new HVAC system.
Evaporative Air Conditioning
Evaporative air conditioners is a device that is not very common just because people don’t know about them or hear about them like they do regular air conditioning systems. Evaporative air conditioning is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems, which use vapor compression or absorption refrigeration cycles. The temperature of dry air can be dropped significantly through the phase transition of the liquid water to water vapor which will cool air using much less energy than refrigerants. Evaporative air conditioning is most commonly found in dry climates such as deserts.
Geothermal HVAC systems
Geothermal HVAC systems are the best choice when you are trying to save the environment. The basic geothermal HVAC system consists of three parts. The first part is called the loop system. There are two main types of loops an open loop and a closed loop. These loop systems carry water or a water antifreeze mixture to and from the system. The next part of a geothermal HVAC system is a heat pump. The geothermal heat pump operates much like a typical air source heat pump. It operates in fifty to sixty degree outdoor airs. Unlike the air source heat pump there is no equipment located outside the home. This unit uses a reversing valve to change the direction of refrigerant flow, this determines whether heat is added or removed from the air in the home. The final part of the geothermal HVAC system is the duct system. This type of duct system is very similar to a conventional duct system however the geothermal ducts are typically larger.
The two types of systems can be quite confusing when it comes to trying to figure out how they operate and how they are different from traditional systems. To sum it all up basically the two types of systems mentioned above don’t harm the environment. They don’t release off any type of refrigerant or debris that could possible be of harm to our planet earth. The best part about these systems is that the price is not much different from traditional systems. They are all around the same price range so just by paying a few extra dollars you can make both your home and our planet earth safe. If you are interested in installing either type of system mentioned above you should contact your local heating and cooling system. They should be able to provide you with all of the information you need. They may even be able to inform you of some other systems that are environmentally safe that you may find to be a better option.
