Research on Solar High-Temperature Absorption Air-Conditioning Systems

Abstract

This paper studies the characteristics and performance of solar higher-temperature absorption air conditioning systems which employed linear concentrating collectors and double-effect absorption chillers. A solar higher-temperature absorption air conditioning system was designed for a small house. Hourly simulations during a cooling season have been conducted using typical meteorological year (TMY) data. Simulation results show that the solar air conditioning system have excellent thermal performance. The linear concentrating collectors can produce hot water of temperature as high as 120-160°C and the COP of the double-effect absorption chillers can reach 1.2-1.4. The system COP during a cooling season can reach 0.426. Meanwhile, the effects of some factors such as climates, volumes of storage tank, areas of collectors on the performance of this solar air conditioning system are also discussed.
