A Research On New Energy Central Air Conditioning System

With the deepening of China’s economic modernization, China’s demand for energy development is also increasing, the construction of energy strategy system has become one of the most important things that can achieve long-term sustainable development. At the same time, with the continuous improvement of people’s living quality, their requirment for work is becoming more and more strict, all types of air conditioning systems in buildings become more popular, air conditioning energy consumption of building energy consumption is becoming a major component. According to some relevant professional statistics shows that the composition of the current air conditioning energy consumption of building energy consumption up to 30%-60%. So how to achieve energy-saving air-conditioning system has always been the core of building energy optimization projects. Besides, during the period of using air conditioner, the usage of freon will exacerbate ozone hole appeared and cause global warming. Therefore, how to effectively promote the optimization and upgrading of energy-saving air-conditioning system is also a matter of environmental protection, it is one of China’s sustainable development strategies that must be solved.In the vast earth, geothermal, solar and other clean energy has extremely numerous distribution, therefore, how to fully develop these energies is always be one of the most important things for energy research and development of all the countries, and it’s also one focus of building energy optimization concerns. Especially, in items of consumption of air conditioner, it has serious significant to achieve the usage of clean energy.First of all, this paper studies the solar air and ground source heat pumps, searchies related reason, at the same time, it summarizes and intruducts shortcomings in the current application.Second, by conbining advantages of two systems, it proposes hybrid combination of both air-conditioning system and describes working schedules, elements, functional advantages of this air conditioner. Then, by using TRNSYS, it starts a long-term energy performance simulation calculation for air-conditioning system, and make a concludsion according to the results of consumption. At the same time, it also runs their air conditioning systems designed complex with a separate ground source heat pump operating conditions of comparative analysis, assessing the efficacy of its energy-saving and cost-effective.Last, in conjunction with specific examples, it analyzes and describes the composition and function of solar-heat pump air conditioning systems. The whole hole system relies on solar and heat pump, it can effectively meet the needs of a variety of living demands as heating and cooling inside the building. It also makes a detailed analysis and research of overall economic benefits.
