Heat pump air-air – saving at times when heating with electricity Bashny.Net

If your house is heated by electricity, heat pumps air-to-air as the most affordable and easy to install, will help significantly reduce heating costs.



Heat pump air-to-air works on the principle of conditioning included heating. But the crucial difference is the efficiency and the operating conditions. Conventional air conditioning, heating included, spent one kilowatt-hour of power it generates 2-3 kilowatt-hours of heat, while heat pumps air-to-air generates about 5-7 kilowatts-hours.

In other words, they are 2.5 times more efficient. In addition, when outdoor temperature is below -5° C air conditioning will cease to operate on heated or sharply reduce heat transfer, resulting in their exploitation becomes simply unprofitable, while most heat pumps are excellent feel at ambient temperatures down to -25° C and even -30° C, no strong while reducing heat generation, although the efficiency may be not so phenomenal.

How heat pump air-to-air?



The device is a heat pump air-to-air similar to air conditioner device, only it uses a number of special engineering techniques. Conventional split-pump system consists of two blocks – internal and external, which has all the basic equipment.

Who produces pumps air-to-air and what was their price?For sale in Russia present residential heat pumps air-to-air manufactured by Panasonic, Mitsibishi, Gree, General, Toshiba, Kentatsu, Goodman, Nibe and others. They differ in the efficiency and range of operating temperatures. Usually at -15° C the efficiency of the pumps starts to decrease, but it depends on manufacturer and model. Some work quite successfully and at -30° C without any noticeable loss in the amount of heat generated, but the power consumption is increased.





As for prices heat pumps air-to-air, the most simple Chinese split systems start from 60 thousand rubles. However, they have low efficiency (~3:1) and narrower temperature limits. The products of famous brands such as Mitsubishi, start from 120 thousand rubles, but they have a higher efficiency (~6:1), higher reliability and wider temperature range.

Advantages and disadvantages heat pumps air-to-airspeaking about the split-primary level, the main shortcomings are the following:
— the high price of the equipment;
— the problem with the distribution of heated air throughout the room (or rooms);
— reduced effectiveness at temperatures below -15°C.

And advantages:
— low cost in comparison with other types of heat pumps;
— simple installation;
— availability of cooling as air conditioners.

However, the second of these disadvantages can be circumvented using other types of heat pumps air to water, which represent the complete water heating system and provide hot water. But these pumps are quite expensive. published
