An absorption refrigerator is a refrigerator that uses a heat source to provide the energy needed to drive the cooling process. Solar energy, burning a fossil fuel, waste heat from factories, and district heating systems are examples of convenient heat sources that can be used.
22 kwi 2023 · Karamangil et al. simulated a solar absorption refrigeration system and studied the effects of various system parameters, such as temperature and solution efficiency. This work showed that increased operating temperature increased the generator and evaporator performances.
•. The thermal conductivity, viscosity and diffusion coefficient should be favorable. •. The volatility of the refrigerant should allow it to be separated from the absorbent without a filter.
1 kwi 2020 · Multi-effect absorption refrigeration cycles, especially the triple-effect absorption cycle, were developed to recover more energy and hence enhance the system efficiency, although those needed higher heat source temperature compared to a double-effect absorption system.
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). This makes the system very effective in the reduction of CO 2 emission and very promising in saving energy; ii.
24 gru 2020 · Abstract: The interest in employing absorption refrigeration systems is usually related to electricity’s precariousness since these systems generally use thermal rejects for their activation.
Efficiency is critical for any refrigeration system, but it’s even more important for absorption refrigerators. That’s because they use a renewable energy source like solar or waste heat, and the more efficiently they operate, the less energy they consume, and the greater the environmental benefits.
