At present, the national standard performance index of air energy is -12℃, and the COP is 2.17. However, the extremely cold variable frequency air energy can be used normally at -50℃. https://www.chaincooling.com/Content/upload/video/202440515/video202401081502573178447.mp4 2024-01-08T15:04:10+08:00 yes no https://www.chaincooling.com/heat-pump/split-extreme-cold-hot-water-heating-unit.html https://www.chaincooling.com/uploads/202440515/small/split-extreme-cold-hot-water-heating-unitee3db824-e106-4b7f-9f35-194c617b148d.jpg Split Extreme Cold Hot Water Heating Unit Split extreme cold hot water heating units use refrigerant to transfer heat. In the heating mode, the outdoor unit absorbs heat from the outdoor air through the refrigerant, and then transfers the heat to the indoor unit for heating. https://www.chaincooling.com/Content/upload/video/202440515/video202401081504571786208.mp4 2024-01-08T15:06:07+08:00 yes no https://www.chaincooling.com/heat-pump/fruit-tree-hibernation-temperature-control.html https://www.chaincooling.com/uploads/202440515/small/fruit-tree-hibernation-temperature-control83d7d301-23ee-438a-98ec-83ec1e59a224.jpg Fruit Tree Hibernation Temperature Control Unit The efficiency of an air source heat pump depends on the outside air temperature and the heat demand of the building it serves. They are best suited for houses with high levels of insulation and specially designed heating systems, such as those in fruit markets. https://www.chaincooling.com/Content/upload/video/202440515/video202401081509468694436.mp4 2024-01-08T15:10:56+08:00 yes no
