The Research On Thermal Comfort And Performance Of Solar Energy-Air Source Pump In Huizhou Residential Building

The Huizhou architecture is flawed because of its humidicool, extensive heating load and so on, so it is particularly important to increase the application of renewable energy while remaining the feature of the architecture in Huizhou. The main contents of this paper are thermal comfort and energy consumption of air-conditioning system in Tunxi. In this paper, it proposes thermal comfort model is suit for summer climate characteristics in Tunxi area, and analyzes the influence on the air-conditioning energy consumption by the meteorological data in relative humidity and the design parameters of temperature and humidity, Through the experiment, we study on the composite energy recovery and utilization of the system performance of the tile-shaped solar collector and air source heat pump integrated system.First of all, this paper studies the effect of courtyard ventilation and natural ventilation on indoor thermal environment basing on the measured data in summer. By the measurement, simulation and questionnaire survey, the paper analyzes the indoor thermal comfort under the condition of natural ventilation in summer and without using the active heating measures in winter in Tunxi area, and presents the linear relationship between the comfortable temperature and the outdoor mean air temperature, which is suitable for the characteristics of summer in Tunxi area. In the meantime, it points out that without the use of active heating measures cannot meet the requirement of indoor thermal comfort in winter.Secondly, on the basis of high relative humidity, humidicool in winter and extensive heating load of Tunxi area, this paper uses simulation analysis software Energy Plus to simulate the effect of relative humidity and temperature on the energy consumption of air conditioner. The results show that high relative humidity in meteorological data is one of the reasons which lead to the increase of air conditioning energy consumption in this area. At the same time, in the premise of meeting the indoor thermal comfort, it is suggested that the relative humidity in the indoor design conditions is no less than 55% and the temperature is no less than 26℃ to reduce air conditioning energy consumption in Tunxi area in summer.Finally, this paper studies the feasibility of the tile-shaped solar collector and air source heat pump integrated system in Tunxi area through experiments. Meanwhile, this paper verifies the heating contribution rate of this system by the solar heat collecting and heat recovery under different conditions of different seasons. The results show that: in summer, the solar energy and the heating contribution rate of the system can reach more than 30% under different working conditions of the integrated system, and the average COP value of the system is about 3.0; Under the abundant sunshine, the confederate heating contribution rate of the system can reach 31.4% by the solar hot water and air cavity hot air combined heat collection in winter and average COP of the system reaches 2.73. Under the inadequate sunshine, the heating contribution rate of the system reaches 17.7% by solar heating collection, the average COP of the system is 2.68. The experimental results show that the integrated system has good effect in various operating conditions, and proves the feasibility of the system.
