Experimental performance evaluation of supercritical CO2 in brazed plate heat exchangers of the tri-partite gas cooler

The experimental data of three brazed plate heat exchangers serving as the gas coolers in a CO₂ system are investigated. The heat exchangers function for the DHW reheating, SH heating, and DHW preheating. The effects of the CO₂ inlet pressure, CO₂ inlet temperature, CO₂mass flow rate, water inlet temperature, and water mass flow rate are analyzed. The system is operated and the experimental data are collected under three modes: DHW operation, SH operation and DHW+SH operation. Experimental data is linked to deliverable number: D4.3.针对二氧化碳（CO₂）系统中作为气体冷却器使用的三台钎焊板式换热器的实验数据展开了研究。此类换热器承担生活热水（DHW）再加热、房间供暖（SH）及生活热水预加热的功能。本研究分析了二氧化碳入口压力、二氧化碳入口温度、二氧化碳质量流量、水侧入口温度及水侧质量流量的影响。该系统在三种运行模式下采集实验数据，分别为生活热水单独运行工况、房间供暖单独运行工况以及生活热水+房间供暖联合运行工况。本实验数据关联可交付成果编号：D4.3。
