Vehicular cooling system with thermal storage

A cooling system for a compartment of a vehicle comprising:

• a blower having an outlet for directing air into a compartment;
• an air/liquid heat exchange having a first heat exchange fluid flow path connected to said outlet and a second heat exchange fluid flow path in heat exchange relation to said first flow path:
• a refrigerant compressor;
• an expansion device;
• a condenser connected between said compressor and said expansion device;
• a liquid/refrigerant evaporator connected between said expansion device and said compressor oppositely of said condenser, said evaporator having a refrigerant flow path receiving refrigerant from said expansion device and a liquid flow path in heat exchange relation with said refrigerant flow path;
• means connecting said liquid flow path in circuit with said second heat exchange fluid flow path to establish a coolant circuit;
• means for circulating a liquid coolant in said coolant circuit;
• a rechargeable thermal storage device in said coolant circuit, said storage device absorbing heat form said coolant when said coolant is above a predetermined temperature and rejecting heat to said coolant when said coolant is below a predetermined temperature;
• an air/refrigerant evaporator having a refrigerant flow path connected to receive refrigerant from said condenser and to discharge refrigerant to said compressor at an airflow path in heat exchange relation with said refrigerant flow path connected to receive air from said outlet and discharge it into the compartment;
• a bypass loop in said coolant circuit for bypassing said air/liquid heat exchanger;
• a valve for selectively opening or closing said bypass loop;
• a pressure sensor located between said compressor and said evaporators;
• and a means responsive to said pressure sensor for operating said valve.
