The term geothermal literally means Earth/Ground (Geo) Warmth (thermal). Geothermal, or ground source warmth pumps, take advantage of the fixed ground or groundwater temperatures to situation your home.
A refrigerant loop with a compressor extracts heat from one side (the ground) and pumps it to the heating loop in your home. It is basically the same process pompe de caldura sol apa pret that happens in your fridge: heat is extracted through a compressor and refrigerant loop from the inside of your fridge/freezer and rejected into your house.
In the summer, the geothermal heat pump reverses its cycle. While in an air-conditioning mode, warmth from the house is rejected into the ground or ground water.
What makes these techniques such a sensible choice for residential heating and cooling is that they do not depend on outside air temperatures. They may hold your home consolationable as efficiently on a windy, zero-degree winter day as on a 40-degree day. Supplied in fact, that your house is well insulated and tight.
Geothermal heat pumps are additionally a really environment friendly and a nicely-designed system will use 25-50% less energy than conventional heating and cooling programs (Supply: US DOE).
Water-to-Water Geothermal Heat Pumps
These types of systems are usually used for heating only. They are put in instead of a traditional fuel or oil furnace to keep your private home warm and supply home hot water.
It is very important know that heat pumps work most efficiently when the temperature distinction between the warm source (ground) and the warmth sink is small.
Ground temperatures range wherever from 50 to seventy five degF, relying on the place you live. This means that geothermal warmth pumps are usually not suitable for standard hot water baseboard functions, which are designed for water temperatures of one hundred eighty degF. Flooring warmth and low-temperature radiators require water temperatures within the range of 95 to 140 degF.
Some newer fashions are now outfitted with so-called desuperheaters that may transfer excess rejected energy from the compressor to heat domestic water for your bathtub, shower and sinks.
Water-To-Air Geothermal Heat Pumps
These types of ground supply heat pumps are typically used once you want air conditioning. The ground “water” is the warmth sink, the place you reject the heat from the house while in air conditioning mode. While in heating mode, energy is extracted from the ground water and “pumped” into the “air” by the compressor. The “air” is distributed via your home via duct work.
In any other case, they perform the same method as water-to-water warmth pumps. And once more, the effectivity of a geothermal heating and cooling system is much better than that of a traditional system.
Necessary To Know
The first step towards making a geothermal warmth pump system be a reliable and efficient heating (and cooling) system on your house is to minimize the heating and cooling requirements with a effectively-insulated building envelope and strategically positioned windows for passive solar gain.
Not solely is your first price reduced, because your system will probably be smaller. You will also tremendously improve the consolation of your home.
These highly environment friendly and reliable systems are finest designed and put in by professionals. It is not beneficial to make this a DIY project. These techniques should meet specific requirements. Particularly the piping laid out in the ground, or right down to the ground water table, have to be designed and put in accurately to ensure that your geothermal heat pump system works as intended.
