Research On Solar Energy Heat Pump Regenerated Rotating Wheel Heating Purification System

With the constant change of people's working and lifestyle,indoor environment has gradually become the most frequent and intimate environment for people to contact.Because this builds the necessity of comfortable,healthy indoor environment to begin to highlight.As an emerging air conditioning system in recent years,the rotary air conditioning system can not only control the indoor temperature and humidity,but also play a role in the adsorption and purification of VOC pollutants,and has great potential in energy conservation and environmental protection.In view of the abundant solar energy resources in our country,this paper presents a kind of air conditioning system with dual function of winter and summer.In the summer working conditions,the heat pump condensing end provides regenerative heat for the wheel,and the gas absorbed and purified by the wheel is sent into the room after cooling by the evaporation end.In winter,a solar collector is added to the regenerative system to improve the performance of the heat pump,and the waste heat generated by adsorption is used for indoor heating.And don't need any other auxiliary heat source.While achieving the goal of energy conservation,it can also solve the problem of winter heating in south China to some extent.Based on the theory of air purification technology and solar heat pump,the selection,working principle and operation mode of each equipment and working medium in the system are described.On the basis of theoretical research,VB was used to improve the mathematical model of rotary wheel coupling adsorption,and TRNSYS platform was used to build the solar heat pump regeneration system model.The outlet temperature,heat production,power consumption,adsorption capacity of the rotor and outlet air temperature of the solar collector system and the heat pump system in typical cities were selected for simulation calculation.It is concluded that the outlet temperature of the solar heat pump can meet the regeneration demand of the wheel,so that the wheel can maintain a certain outlet temperature and good purification effect.When the regeneration temperature is between 35? and 85?,the higher the regeneration temperature is,the higher the system air temperature is,and the higher the concentration of adsorbed toluene is,the better the purification effect is.When the regeneration temperature is higher than 55?,the air supply temperature can reach more than40?,which meets the requirements of indoor air supply.When running at full load,the power required by the system is 4100 k Wh,which has a better energy-saving effect compared with traditional heating air conditioning.Taking a small office building as an example,typical cities with different climate zones are selected to compare and analyze the applicability of the system.It can be seen from the calculation results that the regeneration effect of the system is better in the regions with hot summer and cold winter,warm and mild summer and hot winter,so the adsorption andpurification performance and heating advantages are also more significant,and the energy saving is more superior.In cold areas,it is difficult to meet the demand of heating load.Among them,the system can save up to 76.34% of electricity in the applicable area.Compared with the traditional air conditioning system and the rotary air conditioning system with electrically-assisted solar energy regeneration,the system has high initial investment,but low operating cost,and has the potential to be popularized.
