If you’re someone who is becoming more eco-friendly and you’ve been looking for some green heating and cooling system options, you’ve come to the right place. Although there are more and more of them that are introduced into the marketplace on seemingly an annual basis, we have provided you with a list of five that are becoming the most popular, and with good reason, below:
Absorption. One particular kind of heating and cooling system that more and more people are finding themselves interested in is absorption. This is a type of system that does not rely on electricity, but rather solar power, natural gas or geothermal power. Although it basically works just like another other kind of heat pump, there are two main differences. For one thing, the pump is driven by a gas burner rather than an electric one. Secondly, rather than using a refrigerant, it uses a water-ammonia solution instead. During the wintertime, the solution will absorb the heat of the earth, go through the pump and the heated liquid is used to warm up the house. During the summer, it does the same thing, only in reverse so that the rooms in the home are kept cool instead.
Ice-powered air conditioner. There is a company called Ice Energy that has come up with something that is literally pretty cool. What they did was figure out a way to convert water to ice; then once that process is complete, it is able to run the air conditioning unit. Here’s what makes it energy efficient: Being that ice-powered air conditioners are designed in such a way that they are able to make ice at night when the temperature outside is cooler, when it’s then relied upon to help the refrigerant during the day, you end up using less electricity in order to keep the air conditioner going.
Green coal. Although typically coal is not something that is typically considered to be energy efficient or environmentally friendly due to the amount of greenhouse gases that it emits, there is a process that’s known as gasification which uses the carbon in coal to remove oxygen from water. As a direct result, a clean-burning hydrogen gas is then used for fuel. Then that gas can be placed into a turbine and ultimately used for electricity.
Wind. If you happen to live in a rural area, something else that you might want to consider is wind power. One of the main reasons why it’s such a great option is because it’s completely sustainable. How it works is with the help of a turbine, when there is enough wind blowing, there are magnets connected to the turbine that spin and warm up. When the magnets are close to a copper plate, that’s what helps to warm up water and ultimately become a source of heat too.
Solar (active or passive). If you were to talk to a licensed HVAC technician about some of the advantages of good ductwork design and in the process of the conversation, you happened to mention to them that you were looking for a “green” way to heat and cool your home once it’s time to replace your unit, one of the things that they might recommend is that you look into using active or passive solar energy in order to do it. Solar energy relies on the sun to set the temperature for you home and it’s a great option because it’s one power source that never runs out.
