Air source heat pump water heaters throughout the year in heating mode operation, the impact of unit energy efficiency by a large outdoor weather conditions, and the hot water demand and usually with the seasons and user habits vary Taiyuan water air heating works, only in the name of energy efficiency conditions of the unit operation, it is difficult to accurately and objectively reflect the actual energy savings. Here mainly for air-source heat pump water heaters are concentrated along the Yangtze River and the area south of Taiyuan air, combined with regional weather conditions and the user's actual application, the introduction of annual consolidated operating conditions for air source heat pump hot water unit actual energy efficiency were assessed to determine a more reasonable evaluation criteria. Ultra-low temperature air source heat pump is the use of ultra-low temperature compressor cold regions of Europe and the widespread use of efficient and environmentally friendly low-temperature cooling water projects in Shanxi 410A, at low temperature (-25 ℃) heating EER conventional air source heat pump is 50% -80% , ultra-low temperature air source heat pump units at ambient temperature sometimes dropped significantly attenuated little heat capacity, and fully guarantee the heating effect, the EU common market users using winter cold regions room heating heating and domestic hot water system, the energy saving effect is obvious, Other heating is about 1/3 the cost of heating equipment, family, community, hotels, guest houses, villas and other heating, cooling, domestic hot water first choice Trinity workplace.
