Abstract
A transport refrigeration system (200) having: a refrigeration unit (22) configured to circulate refrigerant through a refrigeration circuit; a battery system (190) configured to power the refrigeration unit; and a heat transfer system (195) thermally connected to the battery system, the heat transfer system being configured to transfer heat from the flash tank to the battery system through the vaporized refrigerant. The refrigeration unit includes: a refrigerant compression device (32) having an inlet and an outlet; a refrigerant heat rejection heat exchanger (34) fluidly connected to the outlet; a flash tank (36) fluidly connected to the refrigerant heat rejection heat exchanger, the flash tank being configured to separate the refrigerant into a liquefied refrigerant and a vaporized refrigerant; and a refrigerant heat absorption heat exchanger (38) fluidly connected to the flash tank and configured to receive the liquefied refrigerant from the flash tank, the refrigerant heat absorption heat exchanger being fluidly connected to the inlet.
