464273 Evaluation of the Performance of Chemically Modified Agrowaste for Solar Refrigeration Applications in Developing Countries
The affinity between the adsorbent (solid material) and the adsorbate (vapor) is an important factor for the refrigeration efficiency. Several researches have investigated the performance of different working pairs (adsorbent-adsorbate) in solar refrigeration systems. The most common working pairs include water-silica gel, water-zeolite, and methanol-activated carbon, among others.
The present paper explores the potential application of agrowastes as adsorbents for solar refrigeration applications since these materials are issue of concern in developing countries such as Mexico. Additionally, Mexico has a high solar irradiation (6 kWh/m2-day) that is a natural resource that could be used for refrigeration in communities with lack of electricity. In order to evaluate the affinity between agrowastes-vapor working pairs, maximum adsorption capacity are determined using the volumetric method.
