As we all know, the air energy heat pump energy saving is very good, but because of the high price of the equipment, the stability of the thermal efficiency of many people are deterred. So spend tens of thousands of dollars to install the air energy heat pump, in the end is it worth getting? Today we will come to a comprehensive understanding of the clear.

I believe that many people install air heat pump, are rushing to its inherent advantages - energy saving, but the air heat pump is not really any place with the perfect embodiment of this powerful advantage Oh, the following four cases, and does not recommend the installation of air heat pump:

Heating area of 100 square meters in the following households (coal to electricity subsidies except households)

The use of air heating is usually more than 40% savings than gas wall-hung boilers, but we also need to consider the cost of purchase. According to the price of air energy heat pumps and wall-hung boilers on the market, this air energy purchase cost and initial installation cost will be much more expensive than installing a wall-hung boiler. If the heating area is small, which means that the operating costs are low, then the air energy heat pump savings will be even less, even if it is 10 years, 20 years, this savings may be only a little more than a little bit of the cost of the price, or even simply can not offset.

To give a simple data, if the heating area is 50 square meters, the installation of wall-hung boilers heating users only need to spend 7,000 or 8,000 to get rid of the home heating and domestic hot water; and the air heat pump to spend more than 2 times to get rid of the home heating and cooling.

In terms of heating, even if the air host energy saving 40%, but 50 square meters of heating area, a month of natural gas gas bill is about 600 yuan, saving more than 200 yuan per month, how many years to save the extra money back? This economic account should be very clear.

Of course, if the heating area of 150 square meters or more, the use of gas heating, the cost per month is about 3,000 yuan, and the use of air energy host, its energy consumption is within 2,000 yuan to get it done, you can save about 1,000 yuan per month, a few years of time to save the installation cost back.

Therefore, the heating area of 100 square meters in the following types of households, or the use of wall-hung boilers is better, while the heating area of more than 100 square meters of households in the air heat pump is very worthwhile to start.

Areas with temperatures below -35°C

If the ambient temperature is too low, the smaller the advantage of the air energy heat pump will be. Air energy heat pump is very easy to frost in winter operation. As of now, China's air energy heat pump technology has been able to cope with the ultra-low temperature environment of -35℃. Under the dual technology of Jet Enhancement + Intelligent Defrost, the heating efficiency of -12 ℃ can still reach more than 2.3, and it can operate normally in -35 ℃ environment, but the energy saving advantage is greatly reduced. Therefore, if it is a long time in the -35 ℃ environment of the region, is not suitable for the use of air energy heat pump.

Gas is less than twice the price of electricity

There are many factors affecting heating costs, such as heating end, building insulation, use of time, etc. These are man-made can be changed, but like the energy price of such factors, we simply can not change. Then we have to choose the heating method according to the local conditions.

Here to teach you a quick trick to determine the method, that is, according to the price of gas and electricity. When the price of one cubic meter of natural gas is 2.75 times the price of one unit of electricity, the two running costs are equal. When the ratio of the price of natural gas to the price of electricity is greater than 2.75, the heating cost of natural gas will be higher than the heating cost of the heat pump. The larger the ratio the greater the advantage of air energy heat pumps in the region.

How did this method come about? A professional has calculated, for the same building, assuming that each cubic meter of natural gas sold at 2.4 yuan, an electricity price of 0.51 yuan, a cubic meter of natural gas produces 8500 calories, gas wall-hung boilers thermal efficiency of 92%; an electricity heat of 860 calories, the average thermal efficiency of the air heat pump is 330%.

As the price of natural gas varies from region to region, in order to get a more generalized relationship, assuming that the price of each cubic meter of natural gas is X yuan, the price of each degree of electricity is Y yuan, assuming that the cost of a dollar of both to get the heat is equal, there are (8,500 × 0.92) ÷ X = (860 × 330%) ÷ Y, then there is X: Y = 2.75, that is to say, when the price of a cubic meter of natural gas is the price of a degree of electricity That is to say, when the price of one cubic meter of natural gas is 2.75 times the price of one unit of electricity, the two operating costs are equal. When the ratio of natural gas price and electricity price is greater than 2.75, natural gas heating costs will be higher than the heat pump heating costs. The larger the ratio of the region the greater the advantage of air heat pumps.

Of course, the air heat pump heating efficiency is affected by the temperature, such as -12 ℃, the air heat pump COP efficiency of 230%, a dollar can get the heat for: (860x230%) ÷ 0.51 = 3878 kcal, is still higher than the gas wall-hung boiler heating the heat obtained by 3258 kcal.

Therefore, in areas where the unit price of natural gas is higher than 2.75 times the price of electricity, it is more cost-effective to use air energy, while in areas where the ratio is lower than 2.75 times, it is more appropriate to use wall-hung boilers. And for areas where the ratio is equal to 2.75 times, it's all the same, and you can go with air energy considering other aspects.

Places with abundant solar, biomass, and geothermal energy resources

Although air energy heat pumps are highly energy efficient, they are still less energy efficient than solar energy (more light than rainy days), biomass, and geothermal energy, so it is not recommended to install air energy if these places where it is located are rich in resources.

And in addition to the above four cases, if you don't know which one is good to install, there is no doubt that you should choose the air energy heat pump, after all, this device brings us more than just saving money, let's take a look at the advantages of the air energy heat pump.

1, energy efficient

Compared with gas and electric heating, air energy thermal efficiency is still the highest, and the energy-saving advantage is highlighted. In the price of coal rose to 1000 yuan now, even more than burning coal are saved.

2、Safety and environmental protection

The equipment adopts environmentally friendly refrigerant, no air pollutants discharged during the whole working process, green and environmentally friendly, very much in line with the current clean heating policy; separation of water and electricity, no poisoning, explosion and other safety accidents, very safe.

3、Intelligent management

The equipment is equipped with advanced IOT system, which can achieve precise temperature control, convenient and quick, without manual guarding, saving manpower.

4、Modularized design

According to the actual need to stop and start the number of units to maximize cost savings, but also free to expand capacity.

5、Simple installation and maintenance

No need to drill a well, as long as there is a suitable place to install, roof, basement, balcony and so on. For commercial use, there is no need to dig and bury pipes in a large area, and there is no need to set up a large heat network, so it can be installed in close proximity to minimize heat loss and maintenance costs in the later stage.

6、End with floor heating, fan coil, radiator

Diversification of heating methods at the end, can be customized according to different scenarios, to meet the modern intelligent life.

7、One machine can be used for two purposes

Nowadays, most of the air energy heat pumps are equipped with refrigeration function, which can be used for heating in winter and refrigeration in summer, which can save the cost of air conditioning investment.

Summarize

Family heating, air energy heat pump in the end worth getting? Still depends on the situation, if there are subsidies, low electricity prices, large heating area, other renewable resources are not rich, the regional temperature is not less than -35 ℃, the family into the air energy heat pump is very cost-effective, on the contrary, you can consider wall-hung boilers or other clean energy equipment.
