People often ask how they could
find their heating and cooling
solution in an economical way by
saving
electricity bills. Well, if you
are one of those searching for the
same answer then the answer is just
right after you! Heat pumps are the
only solution that suits all your
requirements.
According to an estimated report, there are more than 2 million heat pumps used for cooling or heating around the world. However, the opinion still remains divided on their renewable qualifications. However, the heat pumps as the name suggest help
pump heat and are often considered as the energy saving pumps.
In order to apply heat pumps as the major heating devices, low grade heat is collected from the water bodies, atmosphere and also from the ground. Moreover, the use of refrigerant circuit is common in heat generation. The heat is then upgraded by
one electrically driven system or compressor and can even be delivered at a cooperative temperature for heating. Now for cooling, this procedure is simply reversed and the low temperature heat is then collected from inside the building, upgraded and
released to the water, atmosphere and ground.
It is quite difficult to bring together the reliable figures for the total number of heat pumps used for domestic heating in the recent past. However, key to guarantee the competence of heat pump is its valuable installation in terms of the overall
efficiency and also related to carbon emissions. There are different varieties of heat pumps available for usage. The heat pumps can well be categorized by the function including drying, ventilation, domestic hot water, cooling, heating and heat
recovery etc by the heat source- air, water, and ground etc. For buildings, hot water and heating applications, the major heat inputs include water, air or ground.
In few areas of the world, especially in the North America, the heat is more likely delivered as air through the ductwork, either cooler when this is needed and warmer in the heating season. The reversible units are quite common in areas with both
cooling and heating requirements at different times around the year. In contrast, the output is more likely to delivered using the water either through the under floor system or through radiator.
Almost all of the heat pumps as used in the houses use the wider ambiance as their energy source. Air is the most widely available energy source. In the recent years, there has been a growing interest in the geothermal heat pumps also known as
the ground source heat pumps. Typically speaking, these are closed loop system and generally use the ground underneath or surrounding the building.
The water heat pumps are compact units and usually come fully integrated as the energy saving pumps to be used in functioning as the bivalent heating systems. They are especially well suited for renovation and retrofit as they require less
structural work. These systems are simple in concept but are more complicated in design. Heat pumps offers cooling in summer and heating in winter. Many homeowners who have the heat pumps make use of these pumps to heat and cool their homes.
Last but not the least, systems which are appropriately sized are those using the renewable electricity to offer the electrical power can certainly make a great contribution to the higher efficiency.
