An air source heat pump provides efficient heating and cooling to your home, office, or any building that requires such a system. If installed correctly, an air source heat pump can supply 1.5 to 3 times more heat energy to a home than the electricity consumed.
Principle of operation of air source heat pumps:
It works on the principle of vapor compression. An air source heat pump uses a refrigeration system that involves a compressor and condenser to suck it in from one place and release it in another place like a refrigerator system. Before diving into the technology, you should know that air with a temperature above absolute zero always contains and most heat pumps can attract lower temperatures, that is, around -15 degrees Celsius.
Technology used:
The air source heat pump consists of two exchange coils, one of which captures the hot air externally and the other internally forces that air through a heating system. The system consists of four main elements, namely a compressor, a condenser, an expansion valve and a vaporizer, which allow the refrigerant to change from liquid to gaseous form. When the refrigerant passes through the system, the high temperature, which is over 100 degrees Celsius, converts it to its vapor or gas form, while the energy produces heat. Now the gas formed passes through the compressor, which increases its temperature and then passes through the expansion valve, which lets the hot air into the building. Now this hot air passes through the condenser, which transforms the gas back into its liquid form. The temperature produced by the energy of the evaporation phase passes again through the heat exchanger to restart the cycle. It helps the radiators work for the underfloor heating system and for the domestic hot water.
Efficiency of air source heat pumps:
The efficiency of air source heat pumps is measured by a coefficient of action (CoP), which is determined by estimating how many heating units are produced with one energy.
Types of air source heat pumps:
The various types of air source heat pumps are ductless, ducted, short-path, split, packed, multi-zone, and single-sided.
Advantages of air source heat pumps:
There are several advantages that make an air source heat pump ideal for cold climates and these benefits include a lower carbon footprint, the ability to deliver high temperatures down to -15 degrees Celsius, heat your home and water. warm, energy efficient, requires several days for installation, can be alternately charged with wind and solar energy instead of electricity, good and long life with minimal maintenance, ability to provide cooling during summers and heat during winters, no need fuel saving and smart controls, which you can access and control from your phone or tablet.
Conclusion
The issues of sustainability and carbon reduction are key issues of our time. Our duty to reduce carbon emissions, along with a difficult economic climate, makes it difficult for companies to agree to implement new technologies that may soon cost more. Renewable energy and government subsidy plans are a complex area, but there are sustainable solutions to most problems and they need to be explored.
