Place of Origin:
With the continuous improvement of people's demand for comfortable life, there are more and more ways of heating in winter. From the development of heating fuel from burning wood to coal to gas to electricity, it means that with the continuous progress of science and technology, human heating equipment is also developing step by step. Nowadays many homes use floor heating or radiators to get heat, and central heating is on energy. After years of research and technical precipitation, air energy heat pump has been gradually applied to the heating market of "coal to electricity". With the characteristics of environmental protection, energy saving, stability, comfort, versatility and long life, it has formed a huge impact on the traditional heating industry. In 2022, SUNRAIN Air Energy ranked the top two preferred brands in the category of air source heat pump, successively ranked the top 500 preferred brands in the comprehensive strength of real estate development enterprises, and successively ranked the top ten brands in the air energy industry.
About our core technology!
We have one of the core technologies - 1Hz full DC stepless frequency conversion technology. According to the operation condition of the unit, the compressor can realize the free operation of 1Hz stepless frequency modulation, nominal heating COP≥2.65 at -12℃, and the energy-saving function effect is 59% higher than that of other units, so as to realize more intelligent and efficient.
We have the core technology second - S.P.D fine wisdom cream technology. SUNRAIN air products intelligent equipped with the patent S.P.D fine wisdom cream technology can accurately judge the frost point, to achieve the effect of frost frost, no frost, which can reduce the start-stop time, but also energy saving and efficient.
We have the third technology - efficient heating EVI jet enthalpy technology. Efficient heating EVI jet enthalpy technology makes the room become a sauna room in winter, SUNRAIN air can ultra-low temperature products, using the international leading water enthalpy technology, the technology uses the international famous ultra-low temperature compressor, after long-term debugging and research and development of large-scale comprehensive laboratory, making the product in low temperature energy efficiency than similar products more than 30%.
