Effect of volume of evaporator and bed heat exchanger on performance of adsorption chiller

Abstract

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. © 2018 Begell House Inc.. All rights reserved.
