Preformance measurements of heat exchangers

Industry

Dipl.-Ing. Markus Müller

+49-351-4081-5218

Is the heat exchanger properly sized?

We support the industry to improve the efficiency of components for cooling systems and heat pumps.

The ILK Dresden offers the following services:

We determine the preformance and pressure losses of plate heat exchangers (evaporators and condensors) or other heat exchangers for liquids in a defined range.
The measurment is based on the following norms

  • DIN EN 306 Heat exchangers - Methods of measuring the parameters necessary for establishing the performance
  • DIN EN 1117 Heat exchangers - Liquid cooled refrigerant condensors - Test procedures for establishing the performance
  • DIN EN 1118 Heat exchangers - Refrigerant cooled liquid coolers - Test procedure for establishing the performance

The test are preformed at a special developed test rig, which can be seen on the following picture.

Operation range of the test rig

  • Kältemittel: Refrigerants: R134a, R404a, R407C, R410A, R507, (others on request)
  • Coolant: Brine
  • Heat carrier: Water
  • Maximum Performance condensor: 70 kW
  • Maximum Performance evaporator: 60 kW

The measurement systems are calibrated regularly.
