EFFECT OF VOLUME OF EVAPORATOR AND BED HEAT EXCHANGER ON PERFORMANCE OF ADSORPTION CHILLER
摘要
Adsorption chiller technology is one of the most effective ways to convert waste thermal energy into cooling. An
adsorption chiller is a kind of thermal heat pump which is a promising system due to its ability for recovering
heat from the thermal source at low-temperature levels and providing cooling and/or heating effects. It has
advantages such as being environmentally friendly, having no vibration and lower operating costs. Adsorption
chiller has four main components such as an adsorbent bed, evaporator, condenser and an expansion valve. This
study is a parametric model for simulating the performance of single bed silica gel-water adsorption chiller for
adsorption process. By using the developed mathematical model, the change of design parameters on the
performance of the adsorbent bed and the evaporator are predicted. This model not only deals with the heat and
mass transfer inside of the adsorbent bed but also consider the heat transfer from its evaporator, condenser, and
pipes. The model can be reliably used as a design tool for a single bed adsorption chiller and the prediction of the
performance of the chiller without any experiments. The model will provide designers with useful information
about the design of adsorption chiller.
