MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202521086438 A) filed by Pandit Deendayal Energy University on September 11, 2025, for Solar Powered Small Scale Absorption Refrigeration System (ssars) For Storage And Preservation Of Agricultural And Fruit Products.
Inventors include Dr. Anurag Mudgal; Bhaumik Modi; Dr. Vivek Patel; and Dr. Jatin Patel.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: The titled invention discloses a solar powered small scale absorption refrigeration system designed to provide low-cost and energy-efficient cold storage for agricultural and fruit products, particularly in rural areas. The system includes a concentrated solar collector (1) connected to a generator (2) for producing refrigerant vapour using a LiBr-H2O solution. The vapour is condensed in a condenser (3), expanded through an expansion valve (4), and passed into a flooded type evaporator (5) to produce a cooling effect. The refrigerant vapour is absorbed in an absorber (6) and circulated through a solution heat exchanger (7) using a solution pump (8) to complete the cycle. A PRV (9) regulates system pressure, while a cold storage chamber (10) maintains low temperature for preservation. A thermal energy storage unit (11) stores excess cooling for non-solar hours, and a circulation fan (12) ensures uniform cooling, enabling a self-sustained and reliable refrigeration system.
