Temperatures limitation of adsorptive solar powered ice maker using AC35-methanol pair

Abstract

A numerical evaluation of temperatures limits of solar adsorption refrigeration machine cycle using the AC35-methanol pair is presented in this paper. The cold production was better for lower adsorption temperatures and higher temperatures of evaporating and generating. For each 1 kg of adsorbent, 1 kg of ice can be produced for temperatures of generating from 40°C to 100°C according to solar irradiance and ambient temperature. The considered lower adsorption temperature is 10°C, which can allow to produce 9 kg of ice for higher temperatures of generating up to 130°C, this needs 680 kJ of solar irradiance for surface area of 1 m2 of solar collector. The considered higher evaporating temperature is 10°C, which can allow to produce 3.5 kg of ice for higher temperatures of generating up to 144°C, this needs 622 kJ of solar irradiance for surface area of 1 m2 of solar collector.
