Heat pumps for heating: judicious use of free resources

Heat pumps for heating

Outside the window a long time already the 21st century, some villagersstill heat their homes in the old - wood and coal. Some, however, have become proud owners of gas furnaces, but civilization can not reach all, and gas companies is not much in a hurry. What about those whose homes are far away from all the best? Are they still have to be for a few more years old furnace to heat with wood? Fortunately, on the market for a long time there were alternatives - heat pumps for heating, which allows easily from person to warm up or cool down the room to the desired temperature, and even heat the water.

What is a heat pump?

Heat pump - a special device,picks up its energy from the surrounding environment and converts it to heat or cold, depending on the fact that it requires a person at a given time. When you can not only heat the house during the cold season, but also help to cool them in the summer of this equipment. The thus obtained heat can also be used to heat water that will be used for the hot water system.

This is a technical device allows alsosignificantly save money, since the heat produced during operation of the pump, more than three quarters of the costs for free, because it is extracted from the environment, which is what belongs to all mankind, and not to the private entrepreneur.

Heat pump reviews which can be found in large quantities in the network - this is an excellent solution for domestic heating, because they are economical and environmentally friendly.

Principle of operation - the transfer of energy

The principle of operation of such a device aboutthe same as in a conventional refrigerator, available in every kitchen. It is based on the energy transfer in this case the heat from a warm body to a cold. For these purposes, the refrigerant used in the pumps, which when exposed to heat in the chamber begins to evaporate low temperature and pressure indicators. With the increase of these parameters (pressure and temperature) in the compressor, refrigerant gradually gives off heat, condenses in a high temperature and high pressure in the same. Thus, practically from nothing and get warm.

Types of heat pumps

Depending on the source, which gives heat pumps are divided into the following types:

      • geothermal
      • air
      • using waste heat.

Geothermal heat pump

Geothermal heat pump uses the heat obogrevaohlazhdeniya land, groundwater or surface water.

In turn, this equipment can be divided into two types:

  1. closed-circuit pumps,
  2. open-type pumps

The former can be horizontal, verticalor water. Horizontal geothermal heat pumps have a closed type reservoir, which is located sinuously or rings in specially dug trenches horizontal below the freezing depth of soil (by 1.2 meters and more). This method of installation of heating equipment is the most cost-effective for private homes, however, the main criterion for the selection of such a facility is the availability of sufficient area to place it.

Horizontal geothermal pump

Horizontal placement of the heat pump is applicable in areas with sufficient space for installation of the system

Vertical closed-circuit pumps are supplied with a collector,which is placed vertically in a shallow well (2 meters). This option is the placement of the thermal equipment is used in the case when the land size is not too large or the owner does not wish to break the landscape of your garden.

Geothermal vertical pump

Driving vertical geothermal pump, this type of accommodation is suitable for installation in areas with limited space

water pumps have the same header, but placedor rings, or meander in any body of water below the depth of its freezing. This is the cheapest option of all, but there is also some nuances concerning, first of all, the depth and volume of the reservoir, and the data requirements are different for each region.

Water geothermal pump

Installing a water geothermal pump is possible with sufficient depth and pond area

Installation of a water pump

Installing a geothermal pump in the pond requires permission for installation

Geothermal open type pumps typicallyis used as the heat transfer liquid water, which circulates through the system itself in the "open mode", that is, after the passage of the cycle, the water returns back into the earth. This method of heating the house can be used only when the section has a sufficiently large amount of clean water and have a permit for the installation.

Air source heat pump

The air pump as a heat sourceheat removal using the surrounding air. Roughly speaking, it is a regular air conditioner, however, is not quite normal, because the goal of this equipment is fully replace the old radiator panels, which means that their power should be several times the capacity of standard split system. The disadvantage of this pump is a sharp decrease in the conversion efficiency of air into heat when the air temperature decreases below -15 degrees.

Pumps using waste heat

This type of heat pump as a source ofheat removal using any variant of the secondary heat such as the heat of central heating piping. Most often, this method of heating used by large industrial enterprises, which have similar sources of stray heat.

Depending on the heat pump coolant divided into the following categories:

      • air air heat pump
      • heat pump water water
      • Heat pumps air water
      • Heat pump earth water

Heat pumps air air

This type of pump is equipped with an evaporator andcompressor, which are mounted on the outside of the building. Ambient air entering at the evaporator, the coolant transfers its heat, which in turn transmits it to the condenser. Sam capacitor installed inside the premises, which the owner intends to heat. With fan cool air is pumped through the pump capacitor and comes back into the room already warmed up. It can be concluded that air air heat pumps are used for home heating with warm air, and therefore, heating in winter, this option is not effective.

Ventilation Water Water

The heat source in this type of pumps canspeak surface (lakes, rivers, etc.) or ground water (wells), as well as waste water processing plants. The temperature of these sources, even in the winter does not fall below 5 degrees, which allows you to heat premises of any size without problems.

If in the vicinity of the house there is a river or lake,the circuit is laid directly on the bottom of the reservoir, the main condition - the water should be running, and the water body size sufficient for at the bottom can fit the contour of the heat pump.

In the absence of reservoirs, the outline can be laiddirectly into the ground, however, the ground water should be placed in the appropriate depth for mounting. Such a system is quite effective, because the temperature of the ground water even during winter range from +8 to +12 degrees, which ensures optimum operation of the pump and a comfortable environment for human habitation.

Heat pumps water water - great heating equipment for those who live in the vicinity of water bodies, because it is very simple to install this system.

Air pumps are water

air heat pump extracts heat from the waterexterior air mass and transmits it to water. Modern machines of this type are designed for year-round use with winter temperatures not lower than 15 degrees, with a decrease in this indicator, the device work, of course, is, however, the heat generated by them will not be enough to qualitatively warm up the room.

In fact, it is an air conditioner that is capable not only cool the room during summer heat, but also to heat the house in the autumn bad weather and winter frosts.

The advantages of the installation of heat pumps

  • High economic efficiency. If we consider that 1 kilowatt of electricity consumed in the installation work is necessary from 2.5 to 5 and even more kW of heat energy converted, then such units fully justify their high cost.
  • Autonomy and versatility. Use heat pumps can be in any region and in any weather conditions, they do not need to supply any communication, except electricity, but even in its absence would be enough for a small diesel generator capacity of 2-5 kW, to a country house qualitatively heat the area up to 300 square meters . m.
  • Environmentally friendly. During operation, the heat pump is no release of any harmful or poisonous substances.
  • Durability. The device is designed very simply, this is what allows it to operate without major repairs for more than 50 years.
  • Safety of operation. The absence of any inflammable and explosive materials, often used for space heating, heat pumps do absolutely safe. No detail of the device does not heat up to the temperature, which can lead to fire.
  • We do not need any permits and documents. By purchasing a unit, it must be easy to mount and to use at your leisure. No red tape in their offices, no coordination, no papers.
  • Comfort. The device is stable, fluctuations in temperature and humidity in the house of the minimum noise is completely absent, and the possibility to control the pump via the Internet transforms the device into a miracle technique.
  • Perspectives. all energy prices are constantly rising, which makes their use as a heat source is not quite appropriate. To say the same thing about heat pumps just the language does not turn, because the water in the lake, or the air around the house are worth nothing, and therefore, heat your home will always be worth as much, how much you yourself think about it.

Most likely those who value their money and theirtime, are interested in this article, just do not rush to buy, because the price of thermal equipment of this type is very high. However, after weighing all the "pros" and "cons", assessing their capabilities, and decided for themselves that the heat pump you just need. Believe me, you will not regret!
