High temperature air source heat pump to open up the application of air source heat pump technology

High temperature air source heat pump "high temperature" is relative to the current market dominance of the hot water outlet temperature below 55 ℃ air source heat pump products, generally refers to the ambient temperature above 10-15 ℃, the heating temperature at 60, ℃ above the product. Although high-temperature air-source heat pump heat water temperature in only a dozen degrees to improve, but for heat pump technology is a great breakthrough. Our country has a vast territory and a variety of climates. Due to the different geographic functions of the buildings, the heating, air conditioning and hot water systems also vary in form. And with the emphasis on environmental protection and energy issues, a large number of original boiler equipment such as fuel oil, coal and gas need to be rebuilt. Some newly launched heating systems engineering, but also take the initiative to find some energy-saving, safe, pollution-free heating equipment installation. Therefore, energy-saving air-source heat pump technology has become a hot spot in the heating equipment industry. In just a few years, hundreds of domestic and foreign enterprises have entered the air-source heat pump production and sales competition. However, due to the limitations of compression refrigeration technology such as working fluid and condensing temperature, the water temperature of the air source heat pump under heating conditions can only reach about 55 ° C. 55 ℃ water supply temperature For the original use of oil, coal, gas and other boiler equipment, high temperature water engineering projects and the need for high-temperature hot water as a production resource project has been unable or not fully able to meet the system's use requirements, thus limiting the air Source heat pump energy saving technology to promote the application. High temperature air source heat pump technology came into being in this background. The temperature of hot water supply up to 85 ℃ greatly expands the application range of air source heat pump technology. High temperature air source heat pump "high temperature" is relative to the current market dominance of the hot water outlet temperature below 55 ℃ air source heat pump products, generally refers to the ambient temperature above 10-15 ℃, the heating temperature at 60 ℃ above products. Although high-temperature air-source heat pump heat water temperature in only a dozen degrees to improve, but for heat pump technology is a great breakthrough. General air-source heat pump unit in the high temperature conditions, the performance will be greatly attenuated or even unable to run, so high-temperature heat pump products on the choice of equipment components and the use of refrigerants have high requirements, product development and design aspects The cost is also high. High-temperature air source heat pump technology as an efficient, environmentally friendly and energy-efficient heating and cooling technology can be applied to all heating and air conditioning and hot water supply systems and can be combined with other new energy technologies to improve the efficiency of comprehensive utilization. With the deepening of the research on high temperature air source heat pump and the continuous emergence of a large number of new technologies, high temperature air source heat pump technology will continue to develop, its operating efficiency, water temperature, application range will continue to improve to meet various aspects The heating needs.
