More Information
Summary:Provided is a method (300) of controlling an air conditioning compressor in a heating ventilation and air conditioning system having an evaporator (10) including a phase change material. The method includes the steps of (312) measuring an output air temperature of the evaporator (10); (316) determining a state of charge value by calculating a difference between an estimated refrigerant temperature based on the output air temperature of the evaporator (10) and a phase change material freeze temperature and integrating this difference over time; and (324, 328) operating the air conditioning compressor to maintain the state of charge value (106) between an upper and lower limit. Also, provided is a method (200) of recovering braking energy in a vehicle containing a heating ventilation and air conditioning system having the evaporator (10) including the phase change material.
