| Summary: | This paper presents the performance of solar air conditioning system using heat pipe
evacuated tube collector. The currentsolar airconditioning system is not competitive
with electricity driven air conditioning system due to their high investment cost.The
electricity driven chiller has higher peak load during the daytime whereassolar air
conditioning system were converting the low grade solar energy into high grade solar
energy and protects the environment with energy conservation.Meanwhile, its overall
thermal energy conversion efficiency is relatively low compared to conventional air
conditioning.The experiment was carried out for 10 working hours from 08:00 to
18:00during June 2010. The obtained results show that the system technically viable.
The heat pipe evacuated the tube efficiency, coefficient of performance (COP) of the
double effect lithium bromide (LiBr) and water (H2O) absorption chiller, and the
overall system efficiency were analysis. It can be seen that the solar collector efficiency
varies from 26 to 51% during daytime and stored energy can be used for several hours
during nighttime. The absorption chiller COP varies from 0.7 to 1.2 throughout the
experiment and overall system efficiency varies from 27 to 48%. There is further
research needin order to improve the overall system efficiency and it iseconomically
profitable. |
