Mid-Autumn Festival is coming soon, and the heating season is gradually coming. With the increasing promotion of the "coal to electricity" policy, air source heat pumps, with the support of the country, have quickly gained recognition from more users. With a good reputation in the northern heating market, they have become the preferred equipment for more coal-fired boiler transformation; among them, ultra-low temperature air source heat pumps are specially designed for cold areas in the north, and their excellent heating performance is becoming more and more popular.
The working principle of ultra-low temperature air source heat pumps is based on the reverse card cycle principle. It absorbs low-temperature heat sources in the air and passes through the heat pump to provide heating or hot water. It continuously absorbs the heat from the low-temperature source and outputs it to the heated water, directly reaching the predetermined temperature. Its characteristic is that the quasi-two-stage compression jet enthalpy increase heat pump system ensures that the unit can heat normally at -30℃, realizing the stable heating of air source heat pumps in cold areas.
The ultra-low temperature heat pump unit has stable performance, is not affected by the external environment, and operates efficiently all year round; it has strong heating, stable operation, and the outlet water temperature can reach 99°C; it has intelligent management and automatic operation; it has automatic defrosting, energy saving and high efficiency, and the energy efficiency ratio can reach 4 times that of electric heating, saving operating costs.
The ultra-low temperature air source heat pump has the above characteristics, and is especially suitable for heating in areas where the ambient temperature reaches about -40°C in winter, such as high latitudes and high altitude areas such as Northwest China, Northeast China, and the Qinghai-Tibet Plateau. In actual use, Leomon ultra-low temperature units are also recognized by customers for their stability and efficient technical performance.
The ultra-low temperature air source heat pump unit is a high-tech hot water equipment that is energy-efficient, safe, and environmentally friendly. It has a wide range of applications, including villas, office buildings, hotels, hospitals, factories, guesthouses, schools, leisure centers, community centralized heating and other types of buildings for heating in winter, cooling in summer, and making domestic hot water. Moreover, its terminal configuration is flexible, and floor heating, fan coils, and radiators can all be used.
