REFRIGERATION CYCLE DEVICE, EQUIPMENT, AND REFRIGERATION CYCLE METHOD
Document Type and Number:
WIPO Patent Application WO/2013/080350
Kind Code:
A1
Abstract:
This refrigeration cycle device (100) configures a refrigeration cycle, and has: a compressor (101) that compresses a supplied coolant; a coolant retention vessel (105) that retains coolant into which compressor (101) lubricant has become admixed, separates gaseous coolant and liquid coolant, and sends the gaseous coolant to the compressor (101); a coolant conveyance pump (107) that conveys the mixed fluid containing the lubricant and the liquid coolant retained at the coolant retention vessel (105); and an internal heat exchanger (108) that changes the liquid coolant conveyed from the coolant retention vessel (105) by means of the coolant conveyance pump (107) into gaseous coolant, and supplies the gaseous coolant together with the lubricant to the compressor (101). The coolant conveyance pump (107) conveys the mixed fluid containing the lubricant and the liquid coolant retained in the coolant retention vessel (105), and so stable operation becomes possible.
