ET 352.01 Solar heat for cold production
With the increasing demand for refrigeration and air conditioning worldwide, the interest in alternative processes of cold production which can be supplied from renewable energy sources is also growing. One promising possibility is thermal processes. In these processes, thermal energy is used to generate cold. ET 352.01 allows the vapour jet compressor from ET 352 to be operated with solar-generated heat from the HL 313 flat collector.
After sufficient solar thermal heating, the heat transfer fluid from HL 313 is pumped into the vapour generator of ET 352 by the pump from ET 352.01. The pump is operated via ET 352. ET 352 and HL 313 are connected by hoses. The energy added from solar heat is determined by two temperature sensors and one flow rate sensor. The measured values are transferred to ET 352 and can be processed on a PC. They are also displayed directly on ET 352.01.
