IIR documentSummary
As high-efficient car engines with less waste heat are developed, extra heating of the passenger compartment is needed in the cold season. A reversible transcritical CO2 system with gliding temperature heat rejection can give high air delivery temperature which results in rapid heating of the passenger compartment and rapid defogging or defrosting of windows. When operated in the cooling mode, the efficiency of transcritical CO2 systems is higher compared to common (HFC) air conditioning systems, at most dominant operating conditions.
