Study On The Solar Energy Technology Using In Shenzhen Building

The energy resources and environment problem is more and more grim. Because the solar liquid desiccant air conditioning system has the advantage of saving energy, environment friendly and high quality, it has been one focus on the field of building energy efficiency in the recent years. And the temperature and humidity independent control air-conditioning system has been developing and has been improved greatly these years, which takes the solar liquid desiccant air conditioning system into reality program. The solar resource in Shenzhen area is a little rich, and Shenzhen is still a national demonstration city of building solar application.This paper has done some research on the following aspects: 1) Studied the distribution of solar energy resources and the capacity of solar liquid desiccant air conditioning system. The research discovered that when the utilization factor of solar energy is 1.0, 1m~2 solar energy can meet the desiccant requirement of 10m~2 building area. 2) Studied the feasibility of using closed regeneration solar liquid desiccant air conditioning system in Shenzhen. Developed the method for design solar liquid desiccant air conditioning system, and gave an example in Shenzhen to show the feasibility of using closed regeneration solar liquid desiccant air conditioning system. The research discovered that the area of solar collector the system need is too much and the first cost is too high. So the closed regeneration solar liquid desiccant air conditioning system has little value to use at present. 3) Studied the collector-regenerator solar liquid desiccant air conditioning system. This paper proposed a new kind of collector-regenerator system----recycled collector-regenerator system, then studied its theoretical performance and make an experiment to confirm. The experiment results show that:①When the regeneration has become to steady, the temperature is constant.②The mass flow-rate of liquid and regenerating air have great impact on the utilization factor of solar energy, and with the higher mass flow-rate the factor is higher.③With higher regenerating air humidity and higher liquid concentration, the utilization factor of solar energy is lower.④The temperature of liquid can improve the effect of regeneration, also can cut the utilization factor of solar energy. In this experiment, the improvement is a little higher than the reduce volume.⑤The theoretical value of the regeneration temperature is close to the experimental one. 4) Studied the feasibility of recycled collector-regenerator system. Research found that the...
