GEOTHERMAL HEAT PUMPS
GEOTHERMAL HEAT PUMPS - DEFINITIONS
Benefits - Guaranty of Performance
The lexical meaning of "Geothermal", could create confusion, because it refers to the thermal energy that is released from the interior of the earth. In our case, we refer to the utilization of the energy existing in the ground. A geothermal heat pump allows the flow of heat from/to the ground in order to product refrigeration, heating and hot water for domestic use.
Now, what is a "Geothermal Heat Pump"?
Practically is nothing else than a machine which can transport heat loads from cold places to hot, or in the language of engineers, from the "hot sink" to the "cold sink". The same action is executed by the fridge which is in our house and the split type room air-conditioner installed in our lounge and in our office. A difference between the fridge and the air-conditioner is that we can select the hot and cold sink depending on our needs. During the summer we select the environment as the hot sink and our house as the cold one (by selecting operation of refrigeration). The air-conditioner removes heat loads from the interior of our house and it rejects it outside. During the winter we select the interior of our house as the hot sink and the environment as the cold one (by selecting operation of heating). The air-conditioner pumps the heat existing in the environment to the interior of our house.
