Geothermal Heating And Cooling Could Be The FutureTo cool the home when it is hot and to warm it up when it is cold is a basic necessity. There are different ways and equipments to achieve this like forced-air heating and cooling, electric heating or gas heating, heat pumps and geothermal heating and cooling pumps is also one of them. Geothermal heat pumps work in the same way as a regular heat pump, but they make use of the earth's natural temperature for cooling and warming. Thus this process is not only more natural and environmentally sound because it makes use of natural energy to achieve heating and cooling instead of fossil fuels or electricity or other ways, but it also cheaper. There are some districts where geothermal heating and cooling is not only convenient but also price effective. This is how these equipments actually work. A geothermal air conditioning or heating system has its heat exchange coils situated vertically down in the ground and has a condenser receiver. It also has a metering device and makes maximum use of refrigerant for high-energy efficiency. In traditional air conditioners and heat pumps, the heating or cooling effect is achieved by heat exchange between the refrigerant kept in the system and the heat of the environment. This change generally takes place with help of heating coils between refrigerant and ambient air. But the problem arises due to inconsistent temperature of environment. The energy efficiency of systems reduces a lot due to slight temperatures changes. It was to overcome this problem that geothermal heating and cooling devices were discovered. This system makes use of earth's ground temperature instead of temperature of ambient air for heating or cooling purposes. Since earth's temperature is more or less consistent so there is no energy wastage at all. Some additional filters and other devices are required for these kind of pumps. They are bit more expensive than regular pumps and air conditioning systems because a lot of digging needs to be done to install them. But they are very eco friendly and may prove to reduce your overall energy costs in the longer run. If you are worried about the stability and safety of these devices then be assured because contrary to popular misconception, geothermal heating and cooling pumps don't blast off easily. Infact these pumps and system are very sturdy and meant for long run use. Carrier is a good company for buying these systems and all its geothermal pumps are good. Government is also promoting this technology as it is not only environment friendly but also efficient and can reduce your electricity bills by about 50 percent. More research is still under going and many grants have been awarded to engineers working on geothermal energy projects. |
