Description
Technical Field
The invention belongs to a movable multifunctional heat collection box, and particularly relates to a movable solar air heat collection box with various functions of heat supply, drying, airing and the like.
Background
With the air pollution becoming more serious in recent years, many cities in China start to popularize the 'coal to electricity' project, and the air source heat pump is greatly popularized in recent years due to the advantages of no smoke, safe, sanitary, conciseness and the like of the system. However, with the wide range of air source heat pumps, many problems come to the end. In some colder areas, the outdoor air temperature is generally lower than-15 ℃ in winter, the air coils of the outdoor unit start to frost, the heat efficiency of the air source heat pump is obviously reduced, and the air source heat pump cannot normally run even in severe cases, so that the popularization of 'coal power conversion' is limited to a certain extent. Therefore, research on new technologies of defrosting and frosting retardation on the evaporation side is imperative, and many researchers have proposed solutions to this, but not very satisfactory, for example, electrothermal defrosting consumes much power although defrosting is complete; the reverse circulation defrosting is simple and easy to implement, but the reverse circulation defrosting is placed in the air source heat pump, so that the stability of the system is affected. Therefore, it is necessary to develop a technology for preventing the outdoor unit from frosting. The invention has the heat supply function, can utilize clean solar radiation energy to provide a heat source for the small air source heat pump outdoor unit, avoids frosting of the outdoor unit, improves the running efficiency of the system in winter, has the functions of airing and drying, is integrated into a whole, fully utilizes the structural characteristics of the system to realize multiple functions, solves the problem of idle seasons of the existing heat collection system, reduces the electric energy consumption, and achieves the aims of fully utilizing the renewable energy technology, protecting the environment and reducing the pollution, so the development of the system is very necessary.

The invention has the following effects:
the invention combines the heat supply function and the airing function into a whole through the combination of the airing device and the heat collection system, thereby realizing the purposes of dual purposes, functional diversification and the like. The drying tray used in the invention is detachable, the drying tray is assembled when the drying function is started, and the tray can be disassembled when the heating function is started. In the aspect of the airing function, the traditional airing mode has the defects of large occupied area, insufficient heat absorption and overlong airing time, so that grains are mildewed and rotten due to incomplete airing. According to the invention, the grains are placed by using the four airing trays, and the grains are aired and dried by combining the heat collecting system, so that the airing area can be reduced by 3-4 times, the airing time is reduced by half, and the efficiency is improved by 35% -50%; in terms of heat supply, the traditional air source heat pump has the problems of frosting of an air inlet, reduced evaporation temperature, low working efficiency, even incapability of heating and the like when the temperature is lower than-15 ℃, and the invention continuously conveys hot air to the air inlet by combining a snap ring buckle with each air inlet of an air source heat pump outdoor unit, improves the evaporation temperature by 5-10 ℃, improves the COP value of a system by 0.8-1.5 and improves the working efficiency by 30-40%.
And secondly, the traditional heat collector is modified, so that the heat collecting efficiency is greatly improved, and meanwhile, the heat collector is lighter, thinner and more attractive. The common air heat collector has heavy material, low efficiency, and can not efficiently utilize solar energy resources, and has a narrow application range. The invention is characterized in that the traditional heat collector is modified: the vacuum glass cover plate is changed into an ETFE film material with better light transmittance and heat preservation; the common heat absorbing plate is replaced by a punching seam type heat absorbing plate: the common back plate is replaced by a heat-insulating back plate made of novel composite heat-insulating materials. The heat collector is lighter and thinner, simple and elegant in appearance, convenient to combine with other devices or components, and stable and reliable in operation, and heat collecting efficiency is improved.
And thirdly, the invention can control the operation mode of the heat collection box by utilizing an automatic control system, and automatically realize the A, B mode and the conversion of the heat source form in the heat collection system. The automatic control system controls valves at the air outlet main pipe and the air outlet branch pipe in the heat collection system through the switching of the button A and the button B, so that the change of the air outlet direction in the box body is realized. When the button A is pressed, hot air is output from the main pipe and is sent to the air inlet of the outdoor unit, and when the button B is started, the hot air is output through the branch pipe and is sent to the airing tray. When the solar radiation illuminance is lower than the set value, the automatic control system can complete a series of reactions and calculation, so that the air passes through the bypass pipeline to be electrically heated, and the purpose of generating hot air is achieved. The invention connects the automatic control system with the inner parts of the heat collection box to realize the artificial intelligence of the system.
