Title:
DUAL-EFFECT PLATE EXCHANGE UNIT OF COMBINED COOLING AND HEATING SUPPLY
Document Type and Number:
WIPO Patent Application WO/2022/100340
Kind Code:
A1
Abstract:
A dual-effect plate exchange unit of combined cooling and heating supply, consisting of a low-temperature circulation system and a high-temperature circulation system. The low-temperature circulation uses R134a or a similar low-temperature refrigerant; and the high-temperature circulation uses R123 or a similar high-temperature refrigerant. By means of the different physical properties of the two refrigerants and the design of system components of the unit, a cold fluid of -30℃ to 0℃ can be produced and a hot fluid conduction oil can be heated to 100℃ to 120℃; the unit is thus an energy-saving product that replaces traditional combinations of boilers and refrigerators, and has good market application prospects.
