Geothermal Heating, Ventilation And Air Conditioning Systems

Geothermal heating and cooling have long been a reality in many industries.

The geothermal "section" of HVAC (heating, ventilation and air conditioning) is positioned as the greenest and harmonious option of human interaction with the earth (both in private and in the global sense), allowing in its interests underground temperatures for heating in winter and cooling in the summer. These systems can be implemented both in conventional methods for the home, and privately - for example, to affect the microclimate of the pool.


Outside temperatures fluctuate depending on seasonal changes, but the underground temperatures do not change so much due to the properties of earth isolation. More than one and a half meters underground - and temperatures here remain relatively constant all year round.

A geothermal system that, as a rule, consists of an internal manipulator and a buried pipe system, called a grounded circuit and pump as a source of re-injection, benefits from these constant temperatures to provide "free" energy. It takes place in the context of considering energy carriers for various operations (usually water heating, etc.).

Here one should pay attention to the fact that the operation of the HVAC geothermal systems should not be confused with the term "geothermal energy," a process by which electricity is produced directly from the heat in the earth.

Pipes that make up an earthed loop are usually made of polyethylene and can be buried underground either horizontally or vertically, depending on the terrain. If an aquifer is available, engineers may prefer to design an "open loop" system in which a well is drilled into groundwater. The water sways pass through the heat exchanger, and then returns to the same aquifer through "re-injection."

HVAC Geothermal Policy

In winter, liquid circulation through the grounded circuit of the system or this well absorbs well the stored heat from the ground and carries it into a closed room. The indoor practice decreases that response on an more excellent energy also extends it across the place while if this air conditioning operation continued operating in the opposite. In season, the HVAC geothermal policy uses the heat of the house and moves heat in the stone form/pump on the re-injection hole anywhere that considerable heat flows in the cooler ground/aquifer.

Unlike conventional heating and cooling systems, HVAC geothermal systems do not burn fossil fuels to produce heat; they transmit a high or low temperature from the ground. Typically, the electric power is used only to control the fan in the technical unit, the compressor, and the pump.

The geothermal cooling system and the heating system have three main components: a heat pump, a fluid heat transfer medium (open loop or closed system), an air supply system (pipe system) and radiant heating (on the floor or elsewhere).

Unconditional Advantages

Geothermal heat pumps, as well as all other types of heat pumps, were evaluated for their high efficiency. Usually, they move much more energy than they use. For example, the permanent markings of COPs are within 3.0-5.0. This means that for every unit of energy used to power the system, three to five groups are supplied in the form of heat given off.

Regular periodic inspections and replacement of filters, as well as annual cleaning of the coil,  are the only necessary maintenance.

Geothermal effects on the climate are fully approved by "green movements." And experts appreciate them for the "reversible" possibility of impact, that is, heating and cooling. Also, their multitasking makes it possible to equip similar systems with large general systems of the "smart house" type, either private or zoned.
