The heat pump is the hands - free unit for energy

The variety on the market of heating systems gives people "alluring illusion of 'freedom of choice.But think about it ... In reality, we are bound hand and foot.The gas line may be located quite far away (oh, money, moolah), add to this the hassle associated with prolonged voyage on various instances;so that there is a hassle, it's a lot of wasted time and of the same crisp bills.We go further: the liquefied gas - a good option, but certainly not cheap.Diesel - a decent operating costs and a number of significant inconveniences: the need to deliver fuel, the fragrance "even the" plus a boiler needs regular maintenance.And electricity?Of course, a safe, comfortable, environmentally-friendly ... but also the most expensive.A solid alternative to the popular (traditional) heating circuit can be the use of heat pump installations, draw energy of nature.Heat pump their own hands - a real opportunity to reduce heating costs.


heat pump: do not you hear?↑

energy source for a heat pump - electricity.Stop, stop.Do not worry.The pump does not produce heat, it only collects it: to produce a kilowatt of heat energy it will have to "spend" just something about 200 watts.Surprised?That's right.

Fast payback setting ↑

heat pump is ideal for new construction: in this case, you will be able to take into account all the characteristics of the heating system for this kind of nuance, and the unit will be able to fully disclose all of its "possibility".But in the existing system it is easy enough to implement.Cost-effective is it?The question relevant, and "legitimate."Well, for the sake of objectivity, it should be noted that the "integration" of the heat pump from A to Z will cost considerably more expensive than a similar manipulation of gas or diesel equipment.But!A significant advantage is that the running costs make it possible to seriously talk about it payback after a couple of years.

Low power consumption, high levels of comfort, simplicity of maintenance, presentable "appearance" safety suggest a heat pump, as one of the most promising systems for heating.

heat pump - the principle of the ↑

When discussing the principle of the heat pump, often, no matter how it was strange at first glance, think of the refrigerator.Why is that?Just based on the work of TH - technical principle of the refrigerator.Refrigerator removes heat from its "inner" and sends its "out" through the grille at the rear.The heat pump is, by contrast, absorbs energy from the environment and "delivers" it in the heating system.

heat source can serve air, earth, water - the "classic" elements of nature.The advantage of air - in its availability in any case.But the bowels of the earth and the water is not without its "pluses" - because they are the optimal storage tank on the background of relatively constant (within the year) in temperature.

Did you know?↑

For some it will be a sensation for someone not, but the heat pump can not only "warm up" the building, but also cool it.Cooling can be carried out on two technologies: passive and active.The first method (natural) is based on the fact that the "amphibians" subsurface temperature in the summer is lower than smokers, respectively, of the building can be cooled directly.The second way - this is the real conditioning.Reversing VT allows you to control the flow of refrigerant.All the "heat" of the house is transferred to the coolant through the heat exchanger and discharged to the outside.

convincing foreign experience ↑

heat pump, as the technology of "getting" heat gained large-scale spread of many "progressive" countries:annually set by the hundreds of thousands of such installations.The most popular and in demand onaya enjoys in the current EU countries, China and, of course, the United States.

rapid development of this method of providing heat to the final consumer is based not only on the uniqueness of the system itself, but also on the strong government support - the cost of the buyer is partially reimbursed.

... Finally, a truly mass interest in TH reached and "native open spaces."But quite often the information about the machines and the technology itself heard by the manufacturer to the target audience more distorted - the sole purpose of "push" a novelty.However, despite all the elaborate marketing moves, sale, nevertheless, do not grow much.After all, the fact remains - from large upfront investment can not escape.

Not everyone is ready to selflessly to empty your wallet for a promise to sverhekonomit heat.

Considering all the above, we can assume that the buyer can with a great degree of confidence to look at the "exotic" equipment, if it is to know in which cases and signified it - really profitable and indispensable thing.

feasibility of using free resources ↑

If the house supplied with gas, it makes no sense to install VT - is unjustified in terms of financial costs.

But in the absence of the possibility to bring the gas-line (as an option, it is the high cost of the event), the installation of the heat pump is a perfect solution of issues of heat supply.

equipment on diesel fuel, liquid gas, etc. Will not be able to compete with the vehicle nor the moments of safety, nor the level of comfort, not on operational costs.

Heat pumps with their own hands - why not?↑

Despite the "progressive" heat pump technology, the unit can be installed by hand.

The heat pump with his own hands
heat pump with your hands: one of the options for its appearance

Before you begin to "create" to objectively assess the condition of the house.

insulation, if required, should be improved - modern building materials to help you.Schematic diagram of the heat pump "includes" several components: a compressor, evaporator, condenser and expansion valve.Safety devices, such as receiver, filter drier and sight glass you can not use - collecting system manually, you are unlikely to be able to provide all the "stuff factory" and create a unit "like a plant."

  • role of the compressor is best to "give" the most noiseless equipment: You can take, for example, the compressor of the air conditioner imported.With the L-brackets 300 mm, it is fixed to the wall;

  • capacitor need a special tank (volume - 120 liters), made of stainless steel.It is cut into two parts;is inserted into the coil of copper pipe which moves Freon.The tank must be welded back, not forgetting a few technical welded threaded connections;
  • as heat exchanger tubes can be used or conventional refrigeration copper plumbing pipes (net);
  • pipes must be rolled into a coil (wrap the bulb).The edges of the coils must be secured (aluminum rails) to increase ravnoshagovosti loops.Ends its output with the help of sanitary transitions;
  • Freonovod coil: the entrance to the capacitor top - out below.With this will not form bubbles;
  • evaporator does not require high temperature, so the plastic container, "a la" barrels (capacity of about 100 liters) is ideal for this purpose;
  • stock and the flow of water can "carry" conventional sewer pipes with gaskets;
  • Evaporator fix with brackets L-400mm;
Mounting evaporator
as an evaporator can be used in terms of a suitable plastic container, it must be set to fixed by means of brackets stand
  • thermostatic valve sold separately (consider the compatibility with its "work of art");

soldering process, Freon filling, etc. Still recommend trusted hands of professionals (safety first);And in general, "experienced eye" before putting the machine into operation will not harm anyone.Do not forget about questions of automation - you need a single-phase trigger relays, fuses, relays temperature.

Attention!The establishment of such equipment without specific skills and deep knowledge in the field of physics - is the risk.If you doubt his abilities and competence, not improvise!Surface acquaintance with the principle of operation and design of the heat pump is not sufficient for the construction of the unit with your hands!

energy sources for heat pumps: especially ↑

energy suppliers - well ↑

When you use the rocky rocks as a source of heat pipe is lowered into the well.

can use a deep, can be more shallow (of course, cheaper).The main thing - the total estimated depth.At one meter wells account for about 50-60 watts of heat.

Correspondingly, to install a capacity of 10 kW VT, required total depth of wells (one well or depth) of 170-200 m.

energy resources reservoir ↑

If the role of a heat source carries the nearest body of watercontour fit to the bottom.The pond must be instantaneous and does not resemble a modest pool.On the one-meter pipe accounts for about 30 watts of power.To install the TH (10 kW) is necessary to lay the contour length of a little over 300 meters.

Pond as a heat source

To shalt not pop up to one meter of the pipeline is set 5 kg.Positive temperature of the water even in the winter - one of the most significant advantages of this option.

use geothermal ↑

chosen as the heat source of land, the pipeline must be "buried" at a depth slightly greater than the depth of freezing (depending on region) of soil.The special preparation of soil, using different fillings is not necessary, but the preference is still necessary to give a wet ground (ideally - with the proximity of groundwater).

Ground loop as a heat source

Although the dry soil is not forbidden: the truth, it will require increasing the length of the circuit.For our heat pump will require 330-500 m contour.For installation thereof requires an area of ​​400-600 square meters.The minimum distance between neighboring pipelines - 0.8 m. The correct calculation and stacking circuit to avoid a negative impact on horticultural crops, their "plantation" you will be able to successfully use and beyond.

Air circuit - money out of thin air ↑

can "collect" the energy from the surrounding air.If you place a ground collector is not possible, this type of pump unit - the best option.

Calculation of the heat pump ↑

What data should be taken into account in the calculation of the heat pump?Exciting question, which in any case can not be ignored.

Indicative list of the fundamental factors in the calculation:

  • purpose of the building;
  • total area of ​​the building;
  • number of floors, the area of ​​each of them;
  • ceiling height;
  • desired (required) temperature control in the building;
  • wall (material layers, thickness);
  • type and total area of ​​glazing;
  • floor (material layers, thickness);
  • cement (a material layer thickness);
  • presence of the ventilation system and its performance;
  • need for hot water, the number of points of analysis;
  • heating devices and their type;
  • presence / absence of land / pond nearby;
  • presence / absence of restrictions on electricity.
