Abrégé

A liquid circulation system comprises a flasher having a plurality of controllably openable and closable ports by which the flasher is intermittently in fluid communication with a low pressure reservoir (LPR), from which a controlled amount of liquid is transferable to the flasher by means of a pressure differential or a height differential between the LPR and the flasher, and with a high pressure reservoir (HPR), from which is dischargeable a fluid at a sufficiently high pressure which will propel the controlled amount of liquid from the flasher to the HPR. In a liquid circulation method, the flasher is subjected to flash evaporation, causing a controlled amount of liquid to be transferred to the flasher from the LPR. In one embodiment, the system increases the thermal efficiency of a working fluid circulation system by subjecting heat depleted working fluid to flash evaporation.
