GEOTHERMAL

Geo means earth, thermal means heat.The energy present under our feet is known

as geothermal energy.Near about 40-50% of total energy is stored

inside earth surface.The temperature in the ground is remain

constant in all over the year.This is the main source that utilized in

geothermal heat pump.

HEAT PUMP

The device which transfer heat to the system from the surrounding with the application of energy and vice versa.

The refrigerant may be R 22(Monochromo dychloro methane)

COMPONENTSa)Compressorb)Condenserc)Expansion valved)Evaporator

GEOTHERMAL HEAT PUMP

The heat pump which use the geothermal heat as main source is known as Geothermal heat pump.

Water is taken as refrigerant to carried out the process.

Components Ground Heat Exchanger Heat pump Air delivery system/Duct work Desuperheater

Ground heat exchanger

The pipes present inside the ground acts as Heat Exchanger.

TYPES:-1.Horizontal Close Loop2.Vertical close Loop3.Open loop4.Lack/Pond close loop

TYPES OF LOOPS

DUCK WORK

This is the instrument which takes heat from or to the room in summer or winter.

DESUPERHEATER

It is the instrument which acts as water heater.

It takes heat from the compression pipe.Due to desuperheater the is more as it

reduces the electric bill.It gives free hot water for domestic use.

WORKING

Geothermal Heating

IN WINTER

Room temperature is 10 degree and ground temperature is 15 degree.

Extract heat from the earth and moves into the room.

The process is carried out in four processes Evaporation-It evaporate water to vapor Compression-It compress the vapor at high temp. &

pressure Condensation-It condense the vapor and make room temp. Expansion-It makes the vapor to form water.

First process makes water to refrigerant and last process makes refrigerant to water.

IN SUMMER

Geothermal Cooling

IN SUMMER

Room temperature is 45 degree and ground temperature is 15 degree.

Heat is extracted from the room and moves into the earth.

The process is carried out in four processes Evaporation Expansion Compression Condensation

First process makes water to refrigerant and last process makes refrigerant to water.

COMPARISON OF GHP WITH OTHER HP

ADVANTAGES

High COP as compare to domestic heat pump.

Reduce electric bill.Environmental friendly.Free hot water.Clean & safeQuiet

Disadvantages

Not wide spread of energyHigh installation costCan not run out of steam

CONCLUSION

So it is essential to save our environment by using the energy present under our feet.

Geothermal Heat pump is the best way of safe environment as well as money.
