Passive Solar Air Conditioning System Design Research In A Rural Area Of ShiHeZi

Shihezi is a typical cold regions, it is an important implementation of regional national energy policy. In this paper, a passive solar house for the study, combined with the geographical features, Shihezi rural areas put forward for a fine-tuning type passive solar air architectural design. Compared with traditional solar house, the system added a basement as a short-term heat storage and heat exchange space to reduce the indoor temperature fluctuations, improve thermal comfort. To verify the reliability of the design, based on preliminary design ideas, combined with our previous examination centers in Shihezi Agricultural consecutive establish a 1: 1 test house model, experimental study was carried out thermal testing. Following experimental studies using Fluent experimental housing conditions in winter and summer thermal simulation software to compensate for spatial distribution of comprehensive experimental test data shortcoming. And then the preliminary design to optimize the design: in the wall designed to fine-tune the capillary channel respiratory system, and the use of new solar air collectors and activities of energy-saving insulation curtain, to achieve the desired ventilation mode.The main results of the research are as follows:(1) A suitable for rural areas Shihezi passive solar air conditioning systems and building integrated design.(2) Experimental results show rooms, summer experiment room temperature lower than the reference room temperature to about 2.9-5.3 ℃; winter test room temperature is higher than the reference room temperature for about 2-3 ℃; the experimental room main room day indoor temperature fluctuation range 2 ℃.(3) Analysis of experimental results obtained, general house heating period each year from mid-October to mid-April, a total of six months, the experiment room can reduce the heating of 1.5-2 months, significant energy savings.(4) The use of numerical simulation methods to study passive solar air conditioning system indoor thermal environment, by analyzing the detailed distribution of the test-room temperature and velocity field, the results optimized trimming type of passive solar air conditioning and building integrated applications system.
