Outside the window a long time the 21st century, some villagers still heat their homes in the old - wood and coal.Some, however, have become proud owners of gas furnaces, but the 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?Do they have to be so for the next several years old stoke the furnace 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 to take away from his environment energy and conve

rts it into heat or cold, depending on the fact that at any given time requires it to people.With the help of this equipment can not only heat the house in the cold season, and cool them in summer.Thus obtained, the heat can also be used for heating water to be used for hot water supply system.

This is a technical device allows also to significantly save money, since the heat produced during operation of the pump, more than three quarters of the costs for free, because produces it from the environment, which is what belongs to all humanity, not some privateentrepreneur.

reviews of heat pumps which can be found in large quantities in the network - this is an excellent solution for residential heating, because they are economical and environmentally friendly.

principle - energy transfer ↑

principle of operation of such a device is about the same as in a conventional refrigerator, available in every kitchen.It is based on the energy transfer in this case the heat from a cold to a warm body.For these purposes, the refrigerant used in the pumps, which when exposed to heat begins to evaporate in the chamber with low temperature and pressure.With the increase of these parameters (pressure and temperature) in the compressor, refrigerant gradually loses heat, condense in a high temperature and high pressure in same.Thus, virtually anything 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 pumps ↑

Geothermal heat pump used for heating \ cooling heat of the earth, groundwater or surface water.

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

  1. pumps closed-
  2. pumps open-

former can be horizontal, vertical or 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 to install the system

Vertical pumps are equipped with a closed-type collector which is placed vertically in shallow wells (up to 2 meters).This option is placing thermal equipment used in the case where the size of the land is not too large, or the owner is unwilling 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 placed a ring or tortuously in any body of water below the depth of its freezing.This is the cheapest option of all, but there's some nuances concerning, first of all, the depth and volume of the reservoir, and for each region, its data requirements.

Geothermal pumps open type is usually used as a heat transfer liquid water that circulatesthrough the system itself in the "open mode", i.e. after the passage of the cycle, the water returns back into the earth.This method of heating the house can be used only if the area has quite a lot of clean water and have a permit for the installation.

air heat pump ↑

air heat pump as a source of heat transfer using the surrounding air.Roughly speaking, it is a regular air conditioner, however, 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 a standard split system.The disadvantage of this pump is a sharp decrease in the conversion factor of air in the heat when the air temperature drops below -15 degrees.

pumps using waste heat ↑

This type of heat pumps as a source of heat transfer using any variant of heat recovery,for example, the heat pipe central heating.Most often, this method of heating used by large industrial enterprises, where there are similar sources of stray heat.

Depending on the type of coolant heat pumps are divided into the following categories:

  • heat pump air air
  • heat pump water water
  • heat pump air water
  • heat pump earth water

Heat pumps air air ↑

Thistype of pump and compressor is equipped with an evaporator, which are mounted on the outside of the building.Ambient air entering at the evaporator transfers its heat to the refrigerant, which in turn transmits it to the condenser.Himself condenser is installed inside the premises, the owner is planning to heat.With fan cool air is pumped through a condenser pump and comes back into the room already warmed.It can be concluded that air air heat pumps can be used for home heating with warm air, and therefore this embodiment winter heating is not efficient.

Ventilation Water Water ↑

source of heat in this type of pump may make the surface (lakes, rivers, etc.) or ground water (wells), and the waste water processing plant.The temperature of these sources even in the winter does not drop below 5 degrees, which allows you to easily heat the rooms of any size.If

vicinity of the house there is a river or lake, the path is laid directly on the bottom of the reservoir, the main condition - the water should be running, and the size of the reservoir sufficient to its bottom can fit the contour of the heat pump.

the absence of reservoirs, the outline can be put directly into the ground, however, the ground water should be placed on a suitable mounting depth.Such a system is quite effective, because the temperature of the ground water even in winter ranges from 8 to 12 degrees, which ensures optimum operation and comfortable environment for human habitation.

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

type pumps air water ↑

air water heat pump extracts heat from the outdoor air masses and transmits it to the water.Modern machines of this type are designed for year-round use of the winter with temperatures no 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 warm the room quality.

In fact, this air-conditioned, which is capable not only cool the room during summer heat, but also heat the house in the autumn bad weather and winter frosts.

benefits of installing heat pumps ↑

  1. high economic efficiency.If we consider that 1 kilowatt of electricity consumed in the operation of the system, falls from 2.5 to 5 kW, and even transformed thermal energy, similar units fully justify their high cost.
  2. Autonomy and versatility.Use heat pumps can be in any region and in any weather conditions, they do not need to fail no communication, except electricity, but even in its absence would be enough for a small diesel generator capacity of 2-5 kW to heat quality villa area of ​​300 square meters.m.
  3. Sustainability.During operation, the heat pump is no release of any hazardous and noxious substances.
  4. durability.The device is designed very simply, this is what allows it to operate without major repairs for more than 50 years.
  5. safe operation.The absence of any flammable or explosive materials are often used for space heating, heat pumps do absolutely safe.No detail of the device is not heated to the temperatures, which can lead to fire.
  6. 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.
  7. Comfort.The device works steadily, fluctuations in humidity and temperature in the house of the minimum noise is completely absent, and the ability to control the pump via the Internet transforms the device into a real miracle-technology.
  8. promising.Prices for all energy is constantly growing, which makes their use as a heat source is not quite appropriate.To say the same thing about heat pumps just language does not turn, because the water in the lake, or the air around the house are worth nothing, and therefore, heat your home is always going to cost so much, how much do you estimate it.heat pump reviews
