In fact, the ultra-low temperature air source heat pump is also one of the air source heat pumps, which is also common in our daily life. Ultra-low-temperature air source heat pumps are generally used for heating. In North China, many hotels, restaurants, hotels and shopping malls will apply ultra-low temperature air source heat pumps. Ultra-low temperature air source heat pumps and air source heat pump are different from each other. So what exactly is an ultra-low temperature air source heat pump? Air source heat pump is an energy-saving and environment-friendly air conditioning technology that uses gas as the cold and heat source to produce cold water and boiled water. However, in the general air source heat pump unit, after the outdoor natural environment temperature is less than zero, the efficiency of the refrigeration compressor is significantly reduced, the coefficient of heat attenuation is relatively serious, and even cannot be operated. The application scope of the unit is greatly limited, and it is only used in the area south of the Yangtze River. For this matter, the ultra-low temperature air energy heat pump, using the ultra-low temperature jet enthalpy increasing technology, can reasonably reduce the unit exhaust pipe temperature, improve the heating capacity and heating COP value under ultra-low temperature working conditions, so that the air source heat pump can be used at the low natural environment temperature of - 25 ℃.
Ultra low-temperature air source heat pump technology has been widely used in various countries because of its high efficiency, environmental protection, energy saving, economic benefits, and high-quality working characteristics. The ultra-low temperature air source heat pump unit adopts the enthalpy increasing technology of jet aircraft to achieve the actual effect of "quasi two-stage reduction", high efficiency, environmental protection, and energy conservation. High-efficiency heating under extremely low-temperature sensing, stable operation, even higher than the water temperature can go to 60 ℃, which is the heating machine in North China.
The ultra-low temperature air source heat pump unit is a new technology air heat pump water heater with high efficiency, environmental protection, energy conservation, safety, and environmental protection, which can be used for winter heating, summer cooling, and daily life boiled water production in various engineering construction sites such as single-family villas, office buildings, hotel restaurants, hospital outpatient clinics, processing plants, hotels, colleges, leisure clubs, residential quarters, etc. The unit heating also has diversified characteristics, and the load side can be an air heater, coil fan, geothermal heating, etc.
