Heat pumps for heating private houses

Thermal energy is practically everywhere: in earth, water, and even in the air.She was there all the time, only removing it learned recently. The fact is that even in the air whose temperature is close to zero, this energy is enough to heat a private house rather considerable area - it just dissipated, and gather it was quite problematic.But not now, when the best minds of mankind developed heat pumps for heating .

heat pump principle has been known for a long time, and use it in terms of alternative energy for heating buildings realized recently.By and large, the heat pump is a certain similarity of the refrigerator, but instead of cooling it generates heat.I never noticed how hot can be a powerful industrial refrigerator outside?This is the effect, about which there is a speech.

heat pumps for heating

home There are four types of heat pumps:

• ground-water;
• water-water;
• water-air;
• air-to-air.

Their names speak for themselves.For example, the heat pump "ground-water" draws heat from the earth, it concentrates and processes in hot water energy that heats the building.In general, you have understood the first word in the title speaks of the heat source, and the second - on the coolant (the pump "air-air" concentrates heat from the air and heats the room hot air).

Each of the four types of heat pumps for heating has its advantages and disadvantages.Take, for example, pump "ground-water" for its normal functioning needs a pretty deep hole.Such heat pumps for heating have a very high efficiency, because the bowels of the earth, it extracts the heat is not lower than 15 ° C.And warm with the help of water to 60-70 degrees Celsius pretty simple temperature.But heat pumps take energy of water or air, we have a little bit more difficult, but unlike the first, does not need to run them well.

In principle, heat pump heating technology equivalent and specific differences in them are not observed.But total they have quite a lot - they allow almost completely eliminate the use of natural resources such as gas, gasoline, diesel fuel or electricity.From the latter to withdraw completely did not work - without electricity the pump will not work.But this does not mean that you will have to pay large energy bills - it is necessary only for the operation of the compressor.Let's just say, for every watt expended electrical energy heat pump produces heat 10-12Kvt.

Heating heat pump

whole process of heat pump heating of the house can be represented as a cycle - it is named after its inventor.Reverse Carnot cycle looks like.The refrigerant (gas like freon familiar to us) under very high pressure through a tiny hole - the capillaries enters the evaporation chamber, which thanks to the very sharp decrease in pressure it evaporates and extracts heat from the interior walls of the evaporation chamber.Last chamber, in turn, removes heat from the water, earth or air circuit.Next comes the selection and compression of vaporized refrigerant compressor - at this moment the gas temperature rises sharply and is its release of the so-called condenser.

In the condenser the refrigerant is at a temperature of from 85 to 125 degrees Celsius.It is a capacitor using a special heat exchanger and heats coolant, which is used for heating.And the same refrigerant cools, giving heat to the liquid, and goes back to the capillaries, to repeat the whole Carnot cycle again and again.

for thermal heating pump control has a special thermostat.When the room temperature reaches the set level, it is activated and the heat pump stops working.Conversely, when the temperature in the house, the pump comes into operation again.

Heating heat pump house

As with many things in our world, heat pumps for heating can not only heat the water or premises, but also to cool them.This is achieved quite simply - the pump is additionally equipped with a reversing valve, and that you will not heat pumps, and versatile microclimate generator that can heat a room, and cool it down.And at the same time reduce the cost of maintaining a comfortable climate about 75%, unlike units operating in the traditional fuels.Hence, the cost of the heat pump - with the installation of the whole system is a pleasure will cost you about 10,000 Euros and above.Everything depends on the power of the pump and the heated area.
