Abstract:
A method of efficiently refrigerating first and second compartments to first and second temperatures, the second temperature being lower than the first temperature, comprising:providing a first evaporator in thermal communication with a first thermal energy storage material, the first thermal energy storage material being in thermal communication with the first compartment; providing a second evaporator; providing a controllable fan to circulate air between the second evaporator and the second compartment by forced convection; and selectively: providing refrigerant flow under pressure to the first evaporator and then through the second evaporator with the fan turned off to maintain the first temperature in the first compartment and remove heat from the first thermal energy storage material; and, providing refrigerant flow under pressure to the second evaporator with the fan turned on to maintain the second temperature in the second compartment.
