Standard compressors proposal for CO 2 condensing units with Transcritical R744 (CO2) heat pumps . Rapport 2414173 - October 2007 CO2 heat pumps can produce a much higher temperature output then a traditional HFC heat pump system. This is thanks in part due to the transcritical process. These heat pumps can heat water all the way up to one-hundred and ninety-four degrees Fahrenheit.

This plot shows the pressure and temperature at different points in the cycle. The 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. 2015-05-28 · CO2 as a Refrigerant — Introduction to Transcritical Operation R744 systems work subcritical when the condensing temperature is below 31 °C (88 °F). R744 systems work transcritical when the gas cooler exit temperature is above 31 °C (88 °F).
