Title:
EJECTOR-TYPE REFRIGERATION CYCLE
Document Type and Number:
WIPO Patent Application WO/2016/143292
Kind Code:
A1
Abstract:
An ejector-type refrigeration cycle for performing a radiative-cooling operation for cooling a fluid to be cooled by using the cold stored in a cold-storage device, wherein it is possible to extend the duration of continuous radiative-cooling. An ejector-type refrigeration cycle equipped with a compressor (11), a radiator (12), and ejectors (20, 25). The ejectors have bodies having the following formed therein: nozzles (21, 32), coolant aspiration ports (22a, 31b), and booster units (20g, 30e) for mixing a sprayed coolant and an aspirated coolant aspirated through the coolant aspiration ports with one another, and boosting the pressure thereof. The ejector-type refrigeration cycle is equipped with cold-storage devices (15, 16, 17) for storing the cold of a coolant, a vaporizer (14) for exchanging heat between a coolant discharged from the booster units and a fluid to be cooled, and discharging the same toward the coolant aspiration ports, and flow adjustment devices (23, 23a, 35, 37, 40) for adjusting the coolant flow (Gnoz) that flows into the nozzles. During the radiative-cooling operation, the flow adjustment devices decrease the channel cross-section of the coolant channels in the nozzles as the pressure difference between the pressure (Pd) of the nozzle intake port-side coolant and the pressure (Ps) of the booster unit discharge port-side coolant decreases.
