Climate control system and method for optimizing energy consumption of a vehicle

A vehicle climate control system comprising:

• an evaporator core for cooling airflow;
• and
• a controller configured to:
• select an initial target evaporator core temperature (Tevap1) from predetermined data based on a passenger set cabin temperature (Tsp) and one or more environmental conditions;
• calculate a dew point temperature (Tdew) based upon the environmental conditions;
• and
• set a target evaporator core temperature (Tevap) based on Tevap1 and Tdew.

A method comprising:

• receiving input indicative of a passenger set cabin temperature (Tsp) and one or more environmental conditions;
• selecting an initial target evaporator core temperature (Tevap1) from predetermined data based on a cabin temperature setpoint (Tsp), interior cabin temperature (Tcab), ambient temperature (Tamb) and solar load (SL);
• calculating a dew point temperature (Tdew) based on Tamb and relative humidity (RH);
• and
• providing output indicative of a target evaporator core temperature (Tevap) based on whether Tevap1 exceeds Tdew.
