PROJECT RESULTS WP4 SOFTWARE AND MODELLING TOOLS FOR LOW ENTHALPY GEOTHERMAL SYSTEMS AND HEAT PUMP DEVELOPMENTS OBJECTIVES D Development a software for simulation the performance of geothermal system, including the heat pump Create the guideline for optimal selection of configuration the heat pump in function to application Create the guideline for optimizer setup between geothermal system and others removable energy Development of new ground source heat pump of high temperature with low GWP refrigerant uring the Cheap-GSHP's project is developed the free software platform (DSS = Dynamic Simulation .........Software) with the friendly user interface. In this software is implemented a special algorithmic for simulation of the heat pumps performances and the ground source heat exchanger performance. Two dierent calculation methods are developed in the first task. One simplified model with easy input for non-expert users. The second mode is for expert users and it is based on full dynamic simulation, including the ground, the building and the heat pump. The software enables to include solar thermal collectors for heating dominant conditions for the recharge of the ground. T he other result is an inventory of the heat pumps with the technologies of the dierent components ........(evaporators, condensers, compressors, compressor drives, lamination mechanisms, refrigerants, controls, others like ejectors) and to create a selection guide line. It includes a cost/benefit guide to help the selection of the best technology for the heat pump considering the working conditions, that will be included in the selection software. The inventory includes also the environmental impact of the use un refrigerants combined with the heat-pump performance. The WP includes also the study of dierent typical plant configurations in combination with other removable energy technologies like solar thermal, wind, photovoltaic and storage systems. The output include a guideline and cost analysis table to help the optimization of the total plant configuration for dierent application, user priorities and the regional energy prices. This information are included in DSS. T he last result is the design and manufacture of a new generation .......geothermal heat pump with natural refrigerant like CO2, used in transcritical cycle and low GWP HFO R1234ze. The heat pump is designed to produce high temperature water, up to 80°C with low temperature dierence. The technology applied is the two stage in partial cascade cycle and the ejector to maximize the performance on the evaporator and reduce the investments on the ground source heat exchanger. This new heat pump prototype is installed at Technical Museum Tesla in Zagreb for the air conditioning of the exhibition room I n conclusion the WP create a software and guideline to help all the user to selection the complex ....geothermal system combination many removable technologies, in this way the result would be to increase a sensitization the people with this new eco-friendly technology. 6 Cheap-GSHPs RESULTS CONCLUSION cheap-gshp.eu
PROJECT RESULTS WP5 DECISION SUPPORT TOOL DEVELOPMENT T OBJECTIVES he objective of WP5 is the development of a user-friendly web application that enables the end-users .......to choose the optimal geothermal technology for their installations. This objective is focused on building: A decision support system (DSS) to identify the best low enthalpy geothermal system composed of GSHE and heat pump in function of the underground, the building loads, the climatic conditions and the owners' criteria. A web platform that gives access to the system through a user friendly interface (GUI). A s a result of the work carried out, the DSS has been developed. It is composed of dierent modules: the ...........databases used to store all the information, the DSS engine that performs the calculations. necessary to provide the user with a series of ranked geothermal system solutions and the web platform that serves as a user interface. The system includes three dierent databases: the DSS database that contains the information about the users and their projects, the solution repository that contains the information about the dierent technologies supported by the DSS and the data model database that contains auxiliary information necessary for performing the calculations. T RESULTS he DSS engine is the part of the software that generates the solution adapted to each user's case and ........return them ranked according to the user's importance. First, the energy demand for each particular case is calculated (in terms of the building type, climate, etc.) and then the solution (combination of technologies, heat pumps, heat exchangers, and renewable and auxiliary support systems). Finally, the dierent solutions generated are ranked based on the preference of the user.
