On April 20, 2020, Mr. Wang, a villager in the Shuangcheng District of Harbin City, Heilongjiang Province, chose to stop winter heating, Mr. Wang initially chose a 5P air-energy heat pump to heat the 85-square-meter home. But to the winter heating period, minus 26 degrees winter temperature so that the air heat pump can not heat, and even installed in the outdoor chassis and piping are frozen, Mr. Wang on the claim that the "low-temperature heating" of the air heat pump is very disappointed.
Mr. Wang in the freezing 6 days later, only to expect a belated air can repair personnel, maintenance workers dismantle the air unit to see, the system, compressor, evaporator, casing heat exchanger and other air parts are all frozen cracks. After the repair, the "low-temperature air unit" finally reluctant to run, but the temperature of Mr. Wang's home is only 13 degrees, the air heating temperature has not gone up.
From October 2019 to April 2020, Mr. Wang used air energy heat pump winter heating, a total of 8430 yuan spent on heating electricity. 8000 yuan of electricity this is the concept of what it is, Harbin City, Mr. Wang before a winter of burning coal heating is only 3,000 yuan of coal money. Air can heat pump as coal to electricity heating equipment, the result of electricity so expensive, talk about conscience?
Air heat pump is in accordance with the "inverse Carnot" principle of work, through the operation of the compressor system, absorbing heat in the air to create hot water. The principle of work sounds like a lofty appearance, in fact, the air can heat pump has a heating effect is poor, power consumption drawbacks, in the operation of heating there is a certain scam. In order to reveal the true nature of air energy, here is a breakdown of the six major disadvantages of air energy heat pumps:
First, the biggest disadvantage of air energy heat pumps is that they are not cold-resistant and have a poor heating effect. The main energy of the air energy heat pump comes from the heat in the air, however, the temperature outside in winter is very low, and the heat in the air is very little, which leads to the heating efficiency of the air energy heat pump to become low, and the power consumption of the air energy heat pump will become more. If the outdoor temperature in winter is as low as below 10 degrees, the air heat pump may be frozen because of the cold, frost and other reasons, unable to carry out normal heating, and become an expensive and power-hungry furnishings.
Secondly, the acquisition cost of air energy heat pump is too high. Rural areas have always been the main battlefield of coal to electricity, farmers' income is not high, the expensive price of air heat pumps deterred. It is reported that even a small air heat pump, the price is more than 10,000 yuan, the initial acquisition cost is too high, coupled with the air heat pump in the later stage of the non-warranty, resulting in rural coal power users in the maintenance of the maintenance of a large sum of money to be shelled out for maintenance costs.
Third, the air heat pump, whether it is installed, or after-sales, are very troublesome. Most of the air heat pumps are produced in the southern region, and the coal to electricity project is carried out in the northern region, the air energy equipment transportation distance is very long, the pre-installation services, the late door-to-door after-sales service also requires a long time to travel to operate, there is a time lag, and is not convenient, and the installation of after-sales costs is a problem.
Fourth , the air energy heat pump is easy to damage. If the home power outage in winter, then the water left inside the air energy heat pump equipment will quickly freeze and freeze, which in turn triggers frost cracks, burst pipes and other damage; if the summer in the hot temperatures when the work is running, then the compressor of the air energy heat pump is very easy to deteriorate, carbonization, which in turn occurs in a burned out situation; if you do not clean up the scale on a regular basis, then the cased heat exchanger in the air energy heat pump will be ruptured, resulting in the entire unit Scrap.
Fifth, the air energy heat pump is large and noisy. Air energy heat pump not only need to install the chassis in the outdoor, but also need to install the host in the indoor, air energy heat pump in the installation is required to be placed in the ventilated ground or the roof of the building, the footprint is very large, is not suitable for the degree of home aesthetics; air energy heat pump is very noisy, but also affects the residents of the normal rest.
