Experimental setup for the investigation of condensation



• construction type: pillow-plate heat exchanger
• 3 pillow-plates (0.3 m width and 1 m in length), 2 vapor channels
• separate cooling media supply for individual pillow-plates (mass flow control, temperature measurement)
• measurement of vapor temperatures along the condensation path

Operating conditions
• condensation heat flows up to 90 kW in total
• operation at pressures from 0.05 to 1.1 bar abs
• operation at temperatures from 10 to 110 °C
• inert gas (nitrogen) feeding via an external gas cylinder bundle
• compliance with ATEX directive 1999/92/EC, BGR 104, TRBS 1201 BGI / GUV-I 5139, DIN EN 60079 and VDE 0165-1
• condensing media: water, isopropyl alcohol, water / isopropyl alcohol mixtures, other flammable liquids possible
• liquid volume of the experimental medium: approx. 100l

Measurement technique
• temperatures: 70 Pt1000 class A four-wire circuit
• pressures: 10 absolute and differential pressures
• flow rates: 4 Coriolis flow sensors for the most relevant measuring points in the cooling media and inert gas, 4 impeller flow sensors for the less relevant measuring points in the cooling media, 1 thermal mass flow sensor
• oxygen sensor
• safety monitoring of the atmosphere
