Performance of a new solid adsorption ice maker with solar energy regeneration

摘要

A predictive model for an adsorption soalr cooling system using the activated carbon-methanol pair and its numerical simulation are presented. This model accounts for instantaneous heat and mass transfers in each one of the machine components along a characteristic average day for each month. The solar powered ice maker consists of the following basic components: a reactor containing an adsorptive bed coupled to a static solar collector covered by Transparent Insulation Material (TIM), a condenser and an evaporator. A uniform pressure mdoel for the reactor is considered. The bed's radial temerpatur distribution is determined by means of a one-dimensinal numberical method based on a finite difference technique.
