Design of a Small Scale Solar Absorption
Refrigeration and Air Conditioning
Abstract: The energy consumption of the air conditioning is drastically increased
along with the development of economic and the improvement of living standard
which brings huge pressure on the energy, power and environment. The energy
consumed by air conditioners accounts for more than 50% of the buildings’ whole
energy consumption. Solar energy as an inexhaustible and pollution-free natural
energy is considered to be the most promising energy in the 21st century. For this
reason the solar energy has obtained international widespread attention. The aim of
this topic is to take advantages of the solar adsorption refrigeration technology and its
distinguished feature, the stronger the solar radiation the greater system capacity, to
achieve continuous refrigeration and air conditioning in summer. This design starts
from solar absorption refrigerating principles, the cycle of continuous cooling process
and the refinement of the whole process of adsorption refrigeration then ends with
designs of solar energy collectors with vacuum tubes, heat storage water tank, etc.
The design of vacuum tube solar energy collectors aims to meet the demand of hot water for absorption refrigeration machine. Then the heat storage water tank aims to
fulfill hot water demand. On the other hand, the heat water tank is equipped with a
electrical heating system, it is back-up energy to provide hot water for absorption
refrigeration machine. According to the refrigerating output the fan coil system and
pipelines are designed. Finally, the 100m2
solar energy collectors with vacuum tubes
drive the absorption refrigeration machine which provides 12KW refrigerating output
and reaches 0.5 COP. It demonstrates that solar powered absorption refrigeration
system which could continuously air conditioning a single construction in Shanghai
during summer is possible.
