China's northeastern region is cold, about seven months a year in need of heating, and air-conditioning products as a clean heating tools are subject to technology, can not be used in extremely cold regions, making it difficult for domestic air-source heat pump products 'Exit.' Recently, Liaoning Province, a high-speed service area heating project bidding conference, Haier air with the latest research and development -35 ℃ 'melt ice' series of air-source heat pump successful bidder. It is reported that Haier 'melt ice' Series uses the latest research and development of a new generation of dual engine supercharged heating system, can be -35 ℃ ultra-low temperature stable operation, the water temperature up to 70 ℃. In one fell swoop domestic air-source heat pump products in the Northeast, Northwest and other ultra-low temperature environment Inaccessible history.
Technical restrictions: Air products afraid of cold out 'off'
In recent years, the coal-to-electricity project has been launched in the northern part of the country. In the northeast China, various policies have been promulgated in all parts of the country to promote coal-to-electricity projects such as 900 million kwh of substituting electricity to be completed by Shenyang in the planned year. Fuel No-combustion zone shall not be the new construction, reconstruction, expansion of 35 tons of steam below 29 MW coal-fired heating boilers and less than 20 steam tons below 14 MW coal-fired non-heating boilers in some areas in Liaoning in 2019-2020 The basic realization of the urban areas without 20 steam tons and below coal-fired boilers, coal-fired boilers in high-pollution coal-fired boilers.
However, due to the technical limitations of domestic air source heat pump products, the Northeast coal 'electricity to electricity' project is very limited in the choice of clean energy products.At present, the domestic air source heat pump products used in the north of the jet enthalpy technology can only be in the lowest - More than 25 ℃ operation in North China can still be used, but can not meet the steady heating needs of the Northeast.
As the bidding project of high-speed service area to connect Changchun, Shenyang, Harbin capital cities in Northeast China is an important artery of transport in northeast China.Because of higher geographical latitude, more across the region, the temperature difference is obvious, the tender side said that with the local Years of temperature conditions, the heating equipment needs to be stable operation at -33 ℃ ultra-low temperature.While participating in the bidding air source heat pump products due to technical limitations can only give -25 ℃ low-temperature operation solution, can not fully meet this requirement, only Unique Haier 'melting ice' a perfect match.
-35 ℃ stable operation: Haier air can break the northeast provinces can not use the air to clean the heating
The successful bidder of Haier's new generation of 'melt ice' series of heat pump products due to the use of the industry's newest generation of twin-engine supercharged heating system can be -35 ℃ ultra-low temperature stable operation, the water temperature up to 70 ℃, single mechanism Heat up to 535kW. At -12 ℃ standard operating conditions, heating efficiency 3.08.
The reason why this heating effect can be achieved is because dual engine supercharged heating system uses the latest research and development of ultra-low temperature single screw compressor heat pump. Comparing with single-stage compression, the heating capacity of the system has also been greatly increased due to the increase of gas production volume, the condensing temperature is as high as 95 ° C, which surpasses that of the existing large-scale scroll compressors for central heating air source heat pumps in the market. In addition, Exhaust and gas mixture of cooling, even if the operation of very low ambient temperature within the core electrical components will not be condensed, significantly improve electrical safety.
Moreover, the melting ice series also achieved intelligent interconnection, users can remotely monitor the operation of APP equipment, remote heating temperature adjustment at this year's CES show, Haier air source heat pump products at the core of the whole house heating solutions and smart bathroom solution Program, the whole family water purification solutions, zero energy solutions together form the world's first set of smart home water solutions to consumers around the world showcase the future of smart home life scenes, get the participants attention.

China's construction thermal design sub-district includes a total of 5 areas, namely hot summer and warm winter area, mild area, hot summer and cold winter area, cold area and cold area, etc. Prior to this, due to technical limitations, the air source in our cold area was delayed Heat pump product heating, melting ice series introduced the domestic use of air to expand the territory to a nationwide.
This is not the first time Haier Air can break through the technical barriers of the industry. As early as 2014, Haier Air could innovated and developed the industry's first CO2 refrigerant control technology, reducing the minimum operating temperature of air to water heater to -25 ℃, The demarcation line was advanced 3,000 kilometers to the north, breaking the industry limitation that previous air-source heat pump products could only be used in East and South China, which was also recognized as an international leader by China National Light Industry Council in 2014.
In 2016, Haier Air applied the technology to commercial water heater products and introduced Beidou Commercial Air-to-Air Water Heater, which provides ultra-high temperature water heater at 90 ℃, far exceeding the 60 ℃ hot water generally provided by the industry and becoming a coal-fired boiler Best alternative
In addition to this technology, to date, Haier Air Energy has also been ranked as one of the world's top 5 technologies including "High Temperature Hot Water Technology in Heat Pump Water Heaters" and has been recognized as the industry's leading brand for three consecutive years. Industry online data show that in 2017 the air energy industry TOP5 growth rate of 31.8%, while the Haier air can increase 51.5%. Haier Air has achieved five consecutive years of double-speed growth in the industry, the growth rate ranked first.According to Zhong Yi Kang statistics, Haier air water heater market share reached 47%, ranking first in the industry.
The reason why Haier Air can constantly break through the limitations of the industry and lead the industry is that the most fundamental reason is that Haier relies on the 'one man and one' model and parallels the global 10 + N R & D system according to user's pain points, and continuously introduces the industry leading air energy technology And products.Industry experts said that the "one man and one man" model is becoming the next social model, and it is bound to bring a 'textbook' reference for the transition of the Internet of Things of all kinds of enterprises.
