At the present time, the most prevalent cooling systems are electrically driven compression chillers, which have a world market share of about 90%. However, thermal cooling systems offer interesting alternatives for use as air conditioners and chillers, especially if they can be driven by low-grade heat from solar collectors or by waste heat from cogeneration units, thereby minimizing pollutant emissions and reducing primary energy consumption. For several decades, scientists have been looking for a suitable cooling technology that can be powered directly by thermal energy.

The development of Ejector Refrigeration Technologies Center (ERTC) focused on the heat-driven ejector refrigerating machines (ERMs) that operate on solar and waste or exhaust heat and using low-boiling environmentally friendly refrigerants.

Ejector cycle has several advantages over other heat-driven refrigeration cycles, including low temperature heat supply, simplicity in design and operation, possibility of sub-zero operation, high reliability and low installation cost. These make the ERMs more attractive than other heat-driven refrigeration machines.

The main objective of ERTC is the collaboration of science and industry with the aim to creation advanced ejector refrigerating machines driven by thermal energy from solar, waste, or exhaust heat sources for commercial application to provide domestic and industrial cooling, refrigeration, and air-conditioning in various areas under different climatic conditions, while meeting modern requirements for efficiency, reliability, and level of automation, as well as ecological and economical standards.
