Abstract
A local delivery truck 10 is provided with a thermal storage system for cooling the truck for a delivery run after the system has been charged during periods of off-peak power demand. This is done by chilling, with a refrigerant evaporator 32, a first high density fluid 24 such as methyl chloroform and circulating the chilled methyl chloroform from the lower part 22 of the storage container 20 to the surface of a second, lower density fluid 28. the latter is an anti-freeze solution such as water-methyl alcohol, and occupies the upper part 26 of the storage container. The chilling and circulating continues until the anti-freeze solution contains the desired amount of ice and slush which has formed at ever lowering temperatures.
