Vapour jet compressor in refrigeration

Unlike standard compression refrigeration systems, vapour jet refrigeration machines do not have a mechanical but a vapour jet compressor. This makes it possible to use different heat sources, such as solar energy or process waste heat, for cold production.

• refrigeration circuit with condenser, evaporator and vapour jet compressor for refrigerant
• vapour circuit with pump and vapour generator for operating the vapour jet compressor
• transparent tank with water-cooled pipe coil as condenser
• transparent tank with adjustable heater as evaporator
• water supply via the lab network or via water chiller to ensure a maximum water temperature of 14°C
• flooded evap. with float valve as expansion element
• vapour generator with heated water jacket (electrically or solar thermally)
• refrigerant R1233zd, GWP: 4
• receiver for refrigerant with individual filling option for each process tank
• control of the experimental plant using a PLC, operated by touch screen
• data acquisition via PLC on internal USB memory, access to stored measured values via WLAN/LAN with integrated router/LAN connection to customer–s own network or direct LAN connection without customer network
