DESIGN AND INVESTIGATION OF ADSORPTION REFRIGERATION UNIT

Abstract

This research deals with design of an adsorption refrigeration plant, working with zeolite-water pair for combined production of cold and heat using a source of driving thermal energy by burning natural gas into the system. The plant is consists of adsorber bed filled with zeolite, the evaporator, the condenser, heat exchangers, the ventilator and the fire chamber. The adsorption system was connected to the air conditioning unit. The plant is capable to work as a heat pump. In this work, measurements were made to describe the change of temperatures in plant, the rate of flow of water in heating and cooling cycles, also to describe the change in heating, cooling and burner powers. The experimental results show that it is possible to supply cold and heat continuously. The coefficient of performance of the plant is raised above 1.4, the heating output power is raised near 2.5 kW.
