Patent number: 9829223Abstract: Aspects of the disclosure provide a system and method for thermal-compression refrigeration. The refrigeration system includes a storage tank that stores a refrigerant condensate from a condenser, a mixing chamber that receives a refrigerant vapor from an evaporator and a portion of the refrigerant condensate from the storage tank, and produces a refrigerant mixture of the refrigerant vapor and the portion of the refrigerant condensate, and a first and second refrigerant compressors between the mixing chamber and condenser. The first and second refrigerant compressors each receives the refrigerant mixture from the mixing chamber, compresses the refrigerant mixture to produce a compressed refrigerant using thermal energy, and is capable of operating in a heater mode or a cooler mode.Type: GrantFiled: April 14, 2017Date of Patent: November 28, 2017Assignee: King Fahd University of Petroleum and MineralsInventor: Maged Ahmed El-Shaarawi

Publication number: 20140260413Abstract: The absorption cooling system is capable of continuous operation both day and night while using only solar power for its basic operation. The system is an absorption type system using phase changes of aqua-ammonia and a storage system for storing chilled refrigerant for operations when solar power is not available. When solar power is available during the day, the system operates according to the principles of absorption cooling systems, and also stores a reserve of chilled refrigerant in the storage unit. The stored refrigerant then continues the absorption process during the night when solar energy is not available, thereby providing uninterrupted cooling during the day, and also at night when solar energy is not available.Type: ApplicationFiled: March 18, 2013Publication date: September 18, 2014Inventors: SEID AHMED MOHAMMED SAID, MAGED AHMED EL-SHAARAWI, MUHAMMAD UMAR SIDDIQUI
