That’s precisely what solar absorption refrigeration systems bring to the table, providing an alternative to traditional refrigeration methods. In this article, we’ll explore the ins and outs of a solar absorption refrigeration system, from its components to its benefits and challenges.
One reason for this situation is the possibility of taking advantage of alternative systems, such as adsorption, when the hot water is below 90 °C . However, the results of the solar adsorption cooling systems show that its performance is yet lower than that of the absorption system (Table 6) and needs improvement.
Adsorption refrigeration technology has been used for many specific applications, such as purification, separation and thermal refrigeration technologies. Solar energy can easily be used in the adsorption cooling systems. The performance of the solar adsorption cooling systems was reported by several researchers.
The following list presents several advantages of absorption refrigeration systems: i. Absorption refrigeration systems can be thermally driven by low-grade heat sources (e.g., engine exhaust) and renewable sources of energy (e.g., solar energy).
Some benefits of solar cooling include reduced peak load on existing power systems and reduced environmental impact, and alternate use of the cooling system between day and night (hybrid solar cooling). 4. What are the challenges of solar cooling?
Plus, it’s a cost-effective way to reduce energy bills in the long run. Solar absorption refrigeration can be used in a wide array of settings, including residential homes, commercial buildings like offices and retail spaces, and various industrial applications such as food and beverage processing, pharmaceutical manufacturing, and data centers.
