Analyzing Air Conditioning Load Bases On Comfort And Ancient Architecture’s Comfort Research

Architecture is one of the basic human activity, and also an integral part of humanculture. Architecture is one of the explicit form of society and culture. For Architecturewith a particular cultural background, the local people’s living environment, lifestyleand working environment are closely linked, and therefore, it can be said thatArchitecture can reflect the local people behavior and psychological. With the rapiddevelopment of society, people’s living standards have improved. People have capacityand want to adjust the indoor environment, which will inevitably lead to more energyconsumption. Construction has become one of China’s social energy consumingindustries. According to the statistics show that in some cities, such as Beijing,Guangzhou, total building energy consumption accounts for35%of total energyconsumption in the local community. In modern society, energy conservation hasbecome a national policy, but energy conservation should be under the premise ofhuman thermal comfort.Firstly, using comfort evaluation of model to evaluate the building comfort underdifferent thermal environments, and show that compared with humidity, temperature isthe significant factor to impact on human thermal comfort. Then use the DeSTsoftware to analysis building air conditioning load in the summer by hourly, simulatethe effect of temperature and humidity to air conditioning load, the results show thatthe relative humidity of the air is more significant than temperature to impact on theload. With design parameters of temperature and humidity increasing the airconditioning load is decreasing, and the decrease number is increasing withtemperature and humidity increasing. Considering factor of comfort andair-conditioning load, we can select design parameters with low temperature and highhumidity as combination. Finally, through the analysis of simulation results we knowthat under the condition of satisfying the thermal comfort of human body, optimumdesign parameter is (25℃,70%).Through analysis of Huizhou traditional architecture indoor thermal environmentfound that ancient indoor thermal environment can’t meet the human thermal comfortrequirements. Build Bayesian Network model of traditional architecture comfort basedon three architecture’s test data. The structure and parameters of Bayesian network aredetermined by using struct-learn algorithm and parameter-learn algorithm. Aftersuccessfully constructed a network model, and the accuracy of model was validated, the results show that the model can accurately predict indoor thermal comfort. And thestudy show that the main factor affecting Huizhou traditional architecture indoorcomfort is temperature.
