Is the heat exchanger properly sized?

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

ILK Dresden offers the following services:

We determine the performance and pressure losses of plate heat exchangers (evaporators and condensors) or other heat exchangers for liquids in a defined range.

The measurement 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 on a special test rig, which can be seen on the following picture.

Operation range of the test rig

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.
