COMPRESSION SYSTEM FOR COOLING AND HEATING PURPOSES

摘要

A compression refrigeration system includes a compressor (1), a heat rejecto r (2), expansion means (3) and a heat absorber (4) connected in a closed circulation circuit that may operate with supercritical high-side pressure. The refrigerant charge and component design of the system corresponds to a stand still pressure inside the system which lower than 1.26 times the critical pressure of the refrigerant when the temperature of the whole syste m is equalised to 60 degrees C. Carbon dioxide or a mixture of a refrigerant containing carbon dioxide may be applied as the refrigerant in the system.
