Advantages and Disadvantages + Videos and Photos

Air heat pump for heating the house in winter conditions. An air source heat pump for heating is one of the most popular alternatives to gas, solid fuel and electric heating. The earliest heat pump was created in 1852 and was named "heat multiplier". Following physical laws, heat could be transferred from a heated to an unheated body. If there is a large amount of energy, then the reverse process can be carried out.

A little later, scientists discovered another principle. A substance that absorbs warm air upon evaporation, and gives up after it becomes condensate. Thanks to this law of physics, our refrigerators and televisions work. The heat pump works the same way only with the opposite effect. Many air conditioner companies use this and sell air conditioners to customers that can both cool and heat indoor air.

How air heat pumps work for home heating

• Absolutely any body, even a cold one, has some kind of thermal energy content. The task of the pump is to transfer all the thermal energy from the winter air to the room.
• In the part that is located on the street there is a special coil with a steamer containing freon. Freon is a substance that has the ability to deform into gas and back. When it evaporates, heat is absorbed even with minus.

• Gas from freon passes into the compressor, under high pressure is converted back into a liquid state.
• Under the influence of pressure, freon finally turns into a liquid state, giving off all the thermal energy received on the street.
• Freon return is formed back.

The power of the heat pump depends on the outside temperature. Therefore, many pumps can be used with additional air heating systems.

Advantages

As advertised, the biggest advantage is in savings. The efficiency of a heat pump depends on the following factors:

• Parameters of the lower limits of heat reduction in natural conditions
• Minimum temperature differences, in which case the heat output will be very small
• The degree of consumption and output of heat energy

The correct use of the pump depends on the factors

1. In regions with cold winters, the heat pump will not perform well. He simply cannot take away enough heat to heat the room.
2. As the space increases, so does the pump demand. Heat exchangers, the number of probes, etc.

   are increasing. At a certain moment, the maintenance of an air, heat pump will simply become unprofitable. Another heating system will be much cheaper

3. The more complex the device, the higher the price for its repair will be. This is an additional disadvantage in case of an increase in the area of ​​the heated space.

ATTENTION! In general, using a heat pump as the main heating medium will be correct only in rare cases.

Therefore, it is recommended to approach this issue comprehensively.

Main characteristics

In general, the consistency of installing a heat pump for heating is estimated at a cost, which includes:

1. Purchase price of the pump itself,
2. Costs for installation, because additional land work may be required.
3. Cost of regular maintenance.
4. Cost of repairs and troubleshooting.

Pump selection by capacity depends on demand

Can be calculated using the formula:

• The highest air temperature in winter,
• The difference between the outside air temperature is calculated with the difference in the room,
• The heat loss of the walls is calculated.

The obtained result will become the required minimum power for your home.

The second calculation is the selection of the required volume for the storage boiler. It is recommended to install this part of the heating system so that the pump can operate for a limited number of cycles. In the supplementary documents for the heat pump, there are tips for the battery capacity of a certain number of cycle rates. The total figure is 30 liters per kilowatt for three starts, 20 liters for five.

It turns out that for a residential building the minimum volume of a storage tank is 400 liters of a heat pump per day.

Conclusion

If after analyzing climatic conditions, soil and careful calculations, you still decide to buy an air heat pump for heating in winter, it is better to entrust this work to a team of professional specialists. After all, the correct choice of equipment depends not only on the power of the equipment.

Masters will calculate the heat output of the soil, select a special highly efficient scheme and make an excellent option for carrying out the work. Therefore, you will not have any difficulties, and you will not regret the correctness of your choice.
