Wu Yuyuan, from the Department of Refrigeration and Cryogenic Engineering, School of Energy and Power Engineering, Xi'an Jiaotong University made a presentation titled "Application of Secondary Generators in Small Pumpless LiBr Absorption Refrigeration Systems".
Traditional lithium bromide absorption chiller heat source often use gas or oil, therefore, the system requires high heat source temperature is not suitable for low-grade solar energy as a heat source, the requirements of solar collectors is relatively high. Therefore, how to reduce the temperature of the heat source as much as possible is the key to whether the green solar energy can be utilized as the heat source of the absorption refrigerating machine.
Guangzhou Institute of Energy CAS has been successful in the production of low-temperature units (80-85 ° C). However, the structure of such models is complex and their cooling capacity is generally above 100 kW, which is not suitable for the development of miniaturization units.
