Title:
COOLING DEVICE, CONTROL METHOD, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/181972
Kind Code:
A1
Abstract:
A cooling device 10 comprising a first evaporation unit 11, a second evaporation unit 12, a first condensation unit 21, a second condensation unit 22, common piping CP, a compressor 30, an expansion valve 40, a first valve 71, and a second valve 72. The common piping CP combines liquid-phase refrigerant LP-COO flowing from the first condensation unit 21 and liquid-phase refrigerant LP-COO flowing from the second condensation unit 22. The first valve 71 adjusts the liquid-phase refrigerant amount LP-COO flowing into the first evaporation unit 11. The second valve 72 adjusts the liquid-phase refrigerant amount LP-COO flowing into the second evaporation unit 12. In addition, the pressure P0 inside the common pipe CP is greater than the respective pressures P1 and P2 inside the first evaporation unit 11 and the second evaporation unit 12. Thus, the length of the piping can be shortened.
