Rotary compressor in the application of heat pump water heater can be expected to wait. In the cold year of 2014, the sales volume of heat pump water heater compressors was 747300 units (including some non special products), an increase of 20.45% year on year, which was lower than that in the cold year of 2013. In terms of heat pump water heater compressor products, changes have taken place. Approved by the General Administration of Quality Supervision, Inspection and Quarantine of the People\\\'s Republic of China and the National Standardization Administration, GB/T29780-2013 Totally Enclosed Motors for Heat Pump Water Heaters for Household and Similar Purposes - Compressors (hereinafter referred to as "Heat Pump Water Heater Compressors") was officially implemented on May 1, 2014. Although the standard has been issued, its role in guiding the product specification is still weak. At present, most ordinary air conditioning compressors are still installed on heat pump water heaters. The compressor product of heat pump water heater was once expected, but from the current discovery status, scale, promotion and market acceptance of the whole machine, there is a slight gap with the industry expectation. On the whole, compared with other water heater products, heat pump water heater products are difficult to be popularized rapidly due to the poor demand and price. Industry insiders also expressed their views on this: the maturity of products and markets requires a certain amount of time to accumulate. In any case, they are still growing. With the implementation of the standards for heat pump water heater compressors, the products are also constantly standardized, which can still be expected.

In recent years, China has paid more attention to energy conservation and emission reduction. Various policies have been continuously introduced and further promoted in various regions of the country. All kinds of clean energy products have also become the most popular thing in the market, such as air energy water heaters. Development Trend of Air Energy Water Heater The air energy heat pump water heater, as a new energy-saving product, was not well known before 2015. Since the implementation and implementation of Beijing\\\'s coal to electricity policy in 2016, slowly, the names of air energy water heaters, air energy heating units, air source heat pumps and other equipment recommended for coal to electricity have appeared in the people\\\'s vision. The development time of air energy industry in China is not long. During the period from 2000 to 2006, air energy technology was introduced and gradually took root in China. After years of development, air energy heat pump has finally occupied an important position in various fields, playing an efficient role in heating, and promoting China\\\'s environmental protection and energy conservation and emission reduction. The development potential of the air energy heat pump industry has been activated. The 5 trillion yuan coal to electricity installation project in the north is simply a big fat in the heat pump industry. The development prospect of air energy can be imagined. According to the analysis and prediction of industry experts, the future development of air energy hot water project: 1. Frequency conversion products are gradually increasing The concept of variable frequency air energy, which was first proposed by anyone, has been difficult to study. However, the first variable frequency air energy heat pump appeared around 2012, setting off a wave of variable frequency in the industry. With more flexible heating capacity, the frequency conversion air energy equipment can effectively respond to a variety of heating and heating needs, and has gained popularity among the public. In the future, with the popularization of air energy in more fields, the proportion of frequency conversion equipment will be higher and higher. 2. Environmental friendly refrigerant becomes mainstream In the process of changing coal into electricity in the north, there are two reasons why air energy heat pumps are valued: The heating efficiency is high enough; No polluting gas is generated. In particular, the second point has brought great changes to the north, where smog occurs frequently every winter. Therefore, as the key material for air energy heat pump to absorb air heat, the use of environment-friendly refrigerant has become a general trend. For example, R410A refrigerant selected by Nuente: as the successor of R22 refrigerant, the ODP (ozone depleting potential value is zero) of R410A refrigerant is harmless to the environment and has occupied a place in the market. With the improvement of everyone\\\'s awareness of environmental protection, the popularization of environmentally friendly refrigerants will become a reality. 3. More diversified products Due to the high efficiency of air energy equipment in heating, the application cases of air energy heat pumps can be seen in all walks of life. The transformation from coal to electric heating in the north has started the popularization of air energy heat pumps in Hebei, Beijing, Shanxi and other regions several years ago; In terms of commercial hot water, hospitals, schools and hotels, which have high requirements for hot water supply, have also installed a large number of air energy heat pumps; Besides agricultural drying, the market demand for all kinds of food materials is increasing year by year. Therefore, rapid processing and drying are indispensable. The air can be dried, which can effectively reduce secondary pollution. The dried food has better quality, and has become the favorite of many food merchants.

At present, according to GEME Xiaobian, there are various heating methods in the market, including air conditioning heating, electric heater heating, gas wall mounted furnace and air energy heat pump heating. In terms of which heating mode is most comfortable, floor heating is undoubtedly the first. Because floor heating is radiation heat dissipation, the heat is from bottom to top, without blowing, and will not drive indoor dust accumulation, giving a comfortable and natural feeling. However, floor heating is only a kind of terminal, and it can only be used with heat source equipment such as gas wall mounted furnace and air energy heat pump
