If you are trying to cool your house, you know how expensive that can be. During the hottest months of the summer, those prices can rise even higher. A typical HVAC system can use as much as 1 amp per kW hour. You have to pay for that electricity being consumed every hour; therefore, reducing the amount of energy you use will reduce the amount of money you have to spend. However, with a typical HVAC system, reducing your energy usage means that you will to reduce your system’s cooling effects. You don’t have to choose, though. There are now solar air conditioning systems that allow you to cool your home using roughly half the amount of energy consumption. Here is how it works.
How It Works
In a typical HVAC system, a refrigerant is piped through a compressor and an evaporator. The refrigerant is compressed, which causes it to heat up. Then, that refrigerant is allowed to expand rapidly, which causes it to shed most of its heat. This causes the refrigerant to cool down rapidly. Air is then piped over the cool pipes and blown into your house. That is the conditioned air. So, reducing your energy usage would require reducing the expense of one of these steps.
Solar air conditioning systems, such as those sold by H&D Air Conditioning, use the energy of the sun to help heat the refrigerant in the compression stage. A solar panel is installed on your roof to capture the heat of the sun. When the refrigerant is piped through the solar collector, it is heated up. That creates pressure and does part of the work of the compressor. The refrigerant then acts as normal. Using the sun to help heat up the refrigerant reduces your energy usage by as much as 50%. That means your power bill could be reduced by as much as 50% during the summer months.
The Hotter It Gets
The obvious benefit of using free solar energy to do part of the work of cooling your home is the amount of money you can save. Furthermore, the system will actually be more efficient the hotter it gets. Since you need to heat up the refrigerant to create the compression, heating it up more will increase the compression faster. So, as it gets hotter throughout the summer months, more of the work will be done by the solar collector.
That means that you can actually save more money during the hotter months of the year, which is unprecedented in HVAC systems. The price of a solar air conditioning system is sometimes seen as prohibitive, but it’s actually an investment. Since solar air conditioning units do not add moving parts, they will not need repairs any more than a traditional HVAC system does. Furthermore, you will be able to save about half of your energy costs. With the high price of energy these days, you could see a return on your investment in as little as just a few months.
After you receive the return on your initial investment, every month will yield what amounts to profit to you.
