Preformance measurements of heat exchangers
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.
