• WP4 Solar combisystems

Workplan

• Preliminary investigations for and development
  of test methods for systems (stores) with
  integrated adapted burner (DTU)
• Update method for calculation of the energy
  performance of solar combisystems in the
  framework of the EPBD (TNO, ITW)
• Update of the Direct Characterisation (DC) test
  method for solar combisystems into a draft
  European standard (TNO)
• Discussion and comparison of different
  performance test methods (e. g. CTSS and (AC)
  DC) e. g. by inter-laboratory comparison test
  (TNO, ITW)

• WP4 Advanced controllers

Workplan

• Development of test methods for controllers
  working with variable flow, e. g. adjusting
  the flow in such a way that a certain
  temperature or temperature difference is
  achieved (ITW)
• Development of test methods for the evaluation
  of the energy consumption of pumps and
  controllers (e. g. based on nominal power and
  operation time) (DTU, ITW)
• Development of test methods for controllers,
  managing both the thermal solar system and
  additional facilities, e. g. the auxiliary
  heating system (SPF, ITW)

• Document describing a test procedure for the
  evaluation of the energy consumption of pumps
  and controllers (e. g. based on nominal power
  and operation time) (DTU, ITW )

• Contribution of ITW to other WP4 activities

• Participation in collector round robin test
• Contribution to development / definition of LCA-
  procedures for solar thermal systems
• Dissemination of specific WP4 results in
  magazines, at conferences and organisation of
  work shops
