Solar Cooling And Heating System

This paper presents an integarted air-conditioning system with solar absorption cooling and solar floor radiant heating aiming at the problem bringed by shortage of electric power and circumstance polluting. The calculating ensample in this paper is a villa in Shanghai. The area of the collector and the capaicity of chiller and other equipments are worked out. This paper simulates the change of the hot water temperature and the instantaneous power of the assistant heater of the solar air-conditioning system in a day and after that the COP and FNP of the solar air-conditioning system are also achieved. The energy consuming and the economic cost of the normal heat pump air-conditioning system and the solar air conditioning system are figured out.The chiller used in small-scale building must be small-sized, so this paper does some studys in designing a small-sized hot water Li-Br absorption chiller. To sum up, with analysis upwards, the advantage of solar air-conditioning system in energy saving and circumstance protecting is obvious.
