Test Fluid-Energy Machines and Components

Development from Prüflabor Wärmepumpen to Testzentrum PLWP

In 2008 our Prüflabor Wärmepumpen (PLWP) at the ILK Dresden was for the first time accredited by DAP Deutsches Akkreditierungssystem Prüfwesen GmbH as part of an accreditation procedure according to DIN EN ISO/IEC 17025.

Since then, we have continuously expanded our range of services and tasks and made it more flexible. In addition to the testing of brine-to-water heat pumps, normative tests of air-to-water heat pumps, refrigeration condensing units, refrigerant compressors, fans and heat exchangers have been integrated into the PLWP product range.

The standard DIN EN ISO/IEC 17025 of 2005, on which the accreditation is based, was fundamentally revised and updated by the international standards committee in 2018. This revision led to a complete conversion and modernization of the management system of the PLWP. The proof of competence of the PLWP to the DAkkS Deutsche Akkreditierungsstelle GmbH based on this revision is still to be carried out in an 18-month cycle.

In order to be able to provide the clients of Testzentrum PLWP with a high-quality range of testing services tailored to their needs, Testzentrum PLWP has been granted the flexibility of accreditation scopes by the DAkkS.

This provides an advantageous instrument with which the needs of clients, authorities or organizations can be met in terms of quality.
At the same time, this flexibility requires a responsible approach to all quality assurance measures. The activities carried out within the flexible scope can be viewed in the DAkkS certificate available below.

A list of the flexibly accredited procedures of the PLWP test centre can be found here.

Test center PLWP

The accredited test centre PLWP at the ILK Dresden was confirmed by the DAkkS as competent according to DIN EN ISO/IEC 17025:2018 for the following testing fields:

Determination of the heating and cooling capacity of fluid energy machines and refrigeration components as well as acoustic determinations on fluid energy machines and refrigeration components were verified.

Our two testing fields include especially measurements of heat pumps, refrigerant compressors, condensing units and heat exchangers (test standards EN 14511, EN 14825, EN 16147; EN 13771-1, EN 13771-2; EN 327, EN 328; DIN EN ISO 3741; DIN EN ISO 9614 and DIN EN 12102).

In the result a test report is created (DAkkS checking-seal), that is internationally acknowledged within the framework of the ILAC-agreement.

The PLWP is internationally recognized as a test center in the ASERCOM (Certification programs - Compressors, Condensing Units), the EHPA (European Quality Label for Heat Pumps) and in CEN HP-KEYMARK Certification system.

 

Service Offer PLWP

The laboratory offers the following services according the accreditation:

  • Performance test of air-water heat pumps
  • Performance test of water/brine-water heat pumps
  • Performance test of refrigeration compressors
  • Performance test of condensing units
  • Performance test of industrial fans
  • Sound measurement of heat pumps or compressors

Additional Test Capabilities

The ILK has many experiecene in Testing out of many different research project. With this knowlege we offer the following test services outside the accreditation:

  • Life-cycle tests at refrigeration compressors
  • Condition and damage analyses at refrigeration compressors
  • Measurements at thermostatic expansion valves
  • Measurements at electrical expansion vales 
  • Efficiency tests of cooling systems
  • Test of domestic refrigerators and tumble dryers
  • Measurment of condensers and evaporators
