On January 10, 2017, Zhang Huanqiu (Secretary of the CPC Jilin Municipal Committee), Liu Fei (Mayor of Jilin City) and other leaders of competent authorities made field visit to Changshenggu Retirement Home of Jilin State-owned Capital Investment Management Co., Ltd in Jilin City, and surveyed the heating effect of air source heat pump developed by Huayu Energy. According to field measurements, indoor temperature still reached 24℃ when the lowest temperature was -4℃ under the outdoor snowfall.
Designed and developed independently by Huayu Energy, this high-power air source heat pump is a high-power, energy-saving, environmentally-friendly two-stage air-compressed cooled-screw water chiller-heater unit under the severe working condition of ultra-low-temperature. Even if extreme low temperature reaches -30℃, it still achieves long-time, efficient and reliable operation, and unit energy efficiency is about 20% higher than that of ordinary air source heat pump. This equipment has been successfully applied across Jilin City, which is highly recognized by the local government and attracts widespread attention in the whole industry.
