Background technology
In the winter time, all there is the heating demand in the most of area of China, and problem such as traditional heating system has the energy consumption height, efficient is low and environmental pollution is serious has influenced China's economic development to a certain extent.
The conservation measures that the pattern of utilizing heat pump to combine with solar thermal collection system is carried out heating has begun to use, and has obtained certain achievement.Wherein, the system of solar auxiliary air source heat pump radiant heating air-conditioning is fit to villa, low layer office building and the grange in the abundant area of solar energy resources, and therefore, this type systematic is paid attention to by people just gradually.Yet, for this type systematic, how to improve solar energy utilization rate, reduce the unit energy consumption, improve the efficient of source pump, it is the difficult point in this field that the assurance system continues efficient operation always, and main cause is: when water temperature is higher in the solar thermal collector, collecting efficiency descends, and solar energy utilization rate reduces; In winter, when outside air temperature was low, the outdoor heat exchanger frosting was serious, and the efficient of air source heat pump also can reduce, and energy consumption raises.
As solar auxiliary air source heat pump radiant heating mode, domestic scholars has designed some new systems, as: direct-expansion type solar energy auxiliary air source heat pump heating air-conditioner pattern, the solar energy direct heating isotype that combines with the air source heat pump heating, these systems have obtained certain achievement, but do not make full use of solar thermal collection system and air source heat pump system, the efficient of system is still lower, and energy consumption and operating cost are still higher, does not produce substantial breakthrough.
Summary of the invention
In order to overcome the problem that prior art exists, the present invention proposes the comprehensive heating air-conditioner of a kind of air source heat pump assisted solar system, purpose is to solve combine with the air source heat pump problem that solar energy utilization ratio is low, the source pump heating efficiency is low of heating system of traditional solar energy, and the present invention is suitable for the heating air-conditioner of villa, low layer office type building and the grange in the abundant area of solar energy resources.
