| For a long time,the problem of energy and air pollution is a matter of close concern to mankind.However,in recent years,the air pollution in China is serious,haze is frequent,and the problem of air pollution is becoming more and more tense.This study first explored the formation of inorganic salt ions,an important part of the outdoor haze.And the rule of its generation is introduced into the room。In order to reduce its concentration,the use of purification heat reflective coating is put forward.Then explore the cleanliness and energy saving effect of the coating also the effect of temperature and humidity on the effect of purification and energy saving.Finally,combined with the optimum temperature and humidity produced by the haze and the optimum temperature and humidity of the paint purification and energy saving effect,the best temperature and humidity in the room was put forward.The study investigated existing concentration of sulphate,nitrate,and some corresponding polluted gases in atmosphere in Beijing,Nanchang,Qingdao cities,made a data fitting research to the concentration of some inorganic salts and pollutant gases.In the study,the curves of sulfate conversion rate change with substrate atomic molar concentration in spring in Nanchang,in winter of Qingdao and Beijing are showed in chart;and the curve of reciprocal of conversion rate of sulfate to reciprocal of substrate of atomic molar concentration are also showed in chart;the curves of nitrate conversion rate changed with substrate nitrogen atom molar concentration and also corresponding reciprocal relationship in spring in Qingdao and in winter in Nanchang were showed in charts.The conclusions are that curves of inorganic salts basically agrees with Michaelis Menten equation(MME)from study and analysis.and the seasons satisfying with the MME;and also there is a range of best suitable temperature and humidity in different season to corresponding maximum conversion rate,separately.However,the best suitable temperature and humidity is the optimum temperature and humidity for a human body,necessary measures should be taken to control it.People spend much time indoors,counting the generation of inorganic salts of air pollutants and the energy saving,the purpose of this paper is to reduce indoor air pollution and reduce energy consumption of air conditioning.through using purification and energy saving coatings.In the study of purification of heat reflective coatings,the Airpak software is used to simulate the indoor negative ion concentration distribution rate under three working conditions:natural hot pressure,natural window and air conditioning and ventilation.By comparing and analyzing the distribution rate of negative ion concentration in the three working conditions to obtain the working conditions of the most retained state of the negative ions in the room.Combining the effect of temperature and humidity on the production of negative ions and the study of the variation of the concentration of negative ions in a special position with time,to obtain the concentration of negative ions in a special indoor position at different temperatures and humidities.A combination of inorganic salts generated by the optimum temperature and humidity and negative ion generation,to determine the optimum purification effect of coating in winter when the temperature is 18 C～24 C,the relative humidity is higher than 50%,to achieve the best purification effect when the summer temperature is 20 C-28 C,the relative humidity is higher than 65%In the study on energy saving of purifying heat reflective coatings,according to the heat reflecting coating material and reflection parameters to choose suitable wall coating and heat reflection coating and set the three tectonic model:the first model is the control group,the second model is the use of wall heat reflective coatings,the third model was the combining use of wall heat reflective coating and window heat reflective coatings.Through the calculation of the energy consumption of three models,it is concluded that when the coating used in Shenyang winter outdoor design temperature is-9 C,and the indoor design temperature is 18 C.the second model indoor heat load is reduced by 2.3%,the use of combined model two and model three in summer and winter indoor heat load increased by 9.7%,When the outdoor design temperature is 30 C in summer and the interior design temperature is 25 C,the model two reduces the indoor cooling load by 0.6%.Model three reduces the indoor cooling load by 33.6%.Change the outdoor design temperature in winter and summer,the design temperature of indoor air conditioning is constant,and it is found that the smaller the temperature difference between indoor and outdoor,the better the energy saving effect of the purification heat reflection coating.And then using Design builder software to simulate the results,the results show that both office and whole buildings in winter and summer have the effect of energy saving.The north of the room,the south of the room and the whole building can save 2.72%,3.94%,and 3.07%respectively in winter.In summer,the room north,the room south and the whole building can save 28.99%,31.15%,and 24.98%respectively.With the combination of model two and model three,the the north room,south room and the whole building can save 18.86%,21.68%,14.76%respectively.On the study of influence of air conditioning temperature on energy saving effect of purifying heat reflective coatings,it is found that the lower the temperature difference between indoor and outdoor,the more obvious energy saving effect of the heat reflective coating.Finally,according to the heat reflective coating to achieve the best cleaning effect and the best energy saving effect,it is suggested that the air conditioning temperature in winter is 18～20 C,relative humidity is higher than 50%.The air conditioning temperature in summer is 22～26 C,relative humidity is higher than 65%which is consistent with the design specifications. |
