WebThe evaporator pressure is at kept at around 3.5 MPa and the gas cooler pressure is nominally around 10 MPa, which is above the CO2 (R744) critical pressure of 7.4 MPa. Hence, this is a transcritical refrigeration cycle. The gas cooler pressure changes in response to changing environment temperature. WebThe critical point of a liquid was discovered by the French physicist Charles Cagniard de la Tour in the year 1822. He observed that carbon dioxide could be liquified at a temperature of 31 o C when 73 atm of pressure was applied, but it could not be liquified at higher temperatures, even when pressures above 3000 atm were applied.
