On September 26, 2021, the Hebei Provincial Department of Industry and Information Technology announced the 21 reviewed and approved "Development Projects of Hebei Province's Passive Ultra-low Energy Consumption Building Industry in 2021", which will be included in the rolling support project database after no objection to the announcement, and will be supported according to the annual budget and project sequencing. After review and selection at all levels, Kcalin was successfully selected by virtue of the STS high-efficiency air-source heat pump project.
China strives to achieve carbon peak by 2030 and carbon neutrality by 2060. It can be predicted that ultra-low energy consumption buildings will become a new trend in the construction industry in the coming decades. In this era of carbon reduction, efficient and energy-saving air-source heat pump has become the preferred solution for low-energy building heating equipment.
Kcalin heat pump R&D and production base is located in Cangzhou Economic Development Zone, Hebei Province. The base has a production line of high-efficiency heat pump and large industrial waste heat recovery heat pump units and large heat exchange equipment. At the same time, it has a high-level and high-quality "comprehensive performance test and experimental research platform of low ambient temperature air source heat pump and heat exchange equipment" with "multi-function", "wide range", "high precision" and "intelligence" in China.
The STS air-source heat pump unit independently developed and produced has made major technical innovation in defrosting, low temperature attenuation, high-efficient operation, noise reduction, etc. After testing by Hefei Institute of General Machinery and the Environmental Energy Institute of China Construction Research Institute, the STS air-source heat pump unit has achieved dual efficiency of refrigeration and heating, and the energy efficiency in the heating season exceeds the national first-level energy efficiency by 20%, which is an alternative to coal-fired boilers Gas boiler is the best choice to realize clean energy heating.
Passive ultra-low energy consumption buildings can not only improve the comfort of the indoor environment, but also significantly reduce the energy consumption of buildings, with the characteristics of high energy efficiency, high comfort and low energy consumption. The rapid promotion and application of air source heat pump in ultra-low energy consumption buildings is of great significance for solving the problems of high energy consumption, carbon emission amplification and high heating energy consumption in China's construction industry, and has broad prospects.
