Project Summary

Description

The health resort is designed for invalids and offers them an option for healthy and relax vacations. Invalid sportsmen can use the resort for preparation for sport competitions. It will be completed in 2007, meanwhile the installations, including the solar system, are already finished. The decision to build a solar system results from the desire to reduce pressure on the environment as low as possible in first place, following with potential energy cost saving. The solar system consists of two solar fields with a total area of 72 sqm. The system is used for tap water heating and preheating of swimming pool water. The tap water is heated and stored in a heat storage with integrated tube heat exchanger and the pool water is heated with two plate heat exchangers. This health resort will operate a whole year and the same holds for the solar system.

Mr. Janez Trdina,
Director of Dom paraplegikov d.o.o:

„We are aware of the growing importance of energy conservation and therefore it was easy to decide to use as many renewable energy sources as possible. With regards to the fact, that our building lies in the sunniest area of Slovenia – 2,292 sunshine hours per year – the solar system was logical choice. One of the first results of the SOLARGE project is the fact, that we will install calorimeters in the solar system and connect it to a building management system.“

Summary

Two liquid gas high temperature boilers are installed for space and hot tap water heating. Rooms are heated by radiators with thermostatic valves. Some parts of the building – therapy, congress room, and restaurant – have air-conditioning systems. Hot tap water as well as sea water is pumped into the pool and preheated by the solar system. It consists of two sections of solar collectors with a total aperture area of 72 sqm. Water heated in the solar collectors flows through a tube heat exchanger, integrated in the heat storage (2 cbm), or through two plate heat exchangers for sea water preheating.

Financing and investment

Introduction

The Health Resort Centre in Pacug was planned in such a way that quality was put on the first plan. The decision about a solar system was made a few years ago. It looks very good today, because liquid gas price increased. The institutions, which financially support the construction of the Health resort, supported our decision. At the end the price per square metre of solar collectors was a little higher than expected.

Development & experiences

Qualitative aspects of the CSTS

As other investors in large solar systems, we will contribute to the campaign for subsidies for such systems.

Summary of experiences / Notices to the project performance

The health resort is designed for invalids and offers them an option for healthy and relax vacations. Invalid sportsman can use the resort for preparation for sport competitions. This Health Resort is meant to become an incubator of ideas on the field of life of invalids.
The resort will be finished in 2007, mean-while the installations, including the solar system, are already completed.
One of the first results of the SOLARGE project is the fact, that we will install calorimeters in the solar system pipeline and connect the solar system to a BMS (Building Management System).
