1 Simplified SHC predesign tool Romain Siré IEA SHC Task 48 meeting n 3 Gleisdorf, 10th-11st sept. 2012

2 Project synopsis Projet ANR HABISOL 2009 Labellisation: DERBI, CAP ENERGIE Start: january 2010, duration: 3 years Budget total: Aide allouée: Partners: TECSOL, PIMENT, CEA-INES, GDF SUEZ R&D, EDF R&D, ENERPLAN Focus: existing and new buildings, all types solar heating and cooling application with ab/adsorption Aim: Systems reliability ; guarantee of performances Public: scientific community, solar energy professional network, investors, etc.

Focus: existing and new buildings, all types solar heating and cooling application with ab/adsorption Aim: Systems

3 1. General presentation of the tool (1/2) Overview : solar cooling, heating and DHW installation solar combi+ and large scale system ab/adsorption systems with FPC/ETC collectors Main goal of the tool : design main components and predict system performances to carry on feasibility studies tool for designer and planner ==> no time consuming, simple, manual optimisation increase reliability ==> validation by comparison with existing installation monitoring data and with other calculation tool, online help, put boundaries, work on outputs compare predicted performances with monitored ones

for designer and planner ==> no time consuming, simple, manual optimisation increase reliability ==> validation by comparison with existing

4 1. General presentation of the tool (2/2) Status : Developped by CEA-INES and TECSOL Excel beta version nearly ready, validation ongoing (RAFSOL, SOLERA, SOLACLIM, SONNENKRAFT, Trnsys TECSOL deck, DHW GRS monitored installations by TECSOL, SOLO method for DHW) next year : VB development and user interface Principle : Data file *.mgp 1 st set of parameters project and system 2 nd set of parameters components RUN hourly 1 year calculation Monthly energy balance scheme Automatic predesign Performance indicators + «garde fou»

next year : VB development and user interface Principle : Data file *.

6 Configuration and scheme : - use and priority selected by the user : cool, heat, DHW scheme automatically proposed 2. Detailed overview (2/4) Ex : solar is used only for cooling Ex : solar is used for cooling and DHW There is a cold back-up

Detailed overview (2/4) Ex : solar is used only for cooling

7 2. Detailed overview (3/4) Components : ab/adsorption chiller : manufacturer database, automatic calculation for Pchiller collectors : manufacturer database, automatic calculation for Scollectors heat rejection : drycooler, drycooler+spray, open wet cooling tower, ground source heat rejection storage and buffer tank : hot and solar one, cold and chiller one automatic calculation of the capacity + DHW supplementary capacity, back-up : hot back-up for heating possible, hot back-up for DHW mandatory, cold back-up for cooling possible

ground source heat rejection storage and buffer tank : hot and solar one, cold and chiller one automatic calculation of the capacity

8 Calculation : hour per hour 1 hour = 1 operating mode (stop, cool, cool+dhw, heat, heat+dhw, dhw) energy calculation component / component electric consumption calculation 2. Detailed overview (4/4) Monthly balance : all energies : Q1, Q3 (dhw), Q4 (heat), Q10 (cold) electrical and water consumption Performance indicators (see L35) : COP, COPelec, etc... «reference» / minimum / maximum performance indicators values Comparison and «best practice» advises See «Calculation of Performance Indicators for Solar Cooling, Heating and Domestic Hot Water Systems» (ENGL)
