<p>A compression refrigeration system includes a compressor (1), a heat rejector (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 system 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.</p> |
