What is the quality of the air source heat pump in Four Seasons Muge? Are there any case projects?

Four seasons muge air source heat pump has good quality. In order to meet the heating demand in the north, ETS technology, namely, gas-liquid double injection control technology, three-valve combined control technology and solid-variable coupling double-flow defrosting technology, is adopted, which increases the stable operation range of the compressor and makes the unit heat strongly and run stably and reliably at -30℃. There are many application projects, including Libin Jiayuan Community in Nangong City, air source heat pump heating project in Chunshui 'an Community, central heating project in Tianjin Jinghai Dafengdui Village, air energy heating project in Lhasa Lan Ou Hotel, heating project in Jinchuan County People's Hospital, and clean energy heating project in Qidaoling Town, Chaoyang, Liaoning Province. , covering all parts of the country.
