Beskrivelse:

Dette projekt omhandlende energioptimering af Gellerupbadet, beskæftiger sig med Gellerupbadets svømmehalsventilationsanlæg. Ventilationsanlægget analyseres, og der undersøges, hvilke krav der stilles til et ventilationsanlæg i en svømmehal. Som ventilationsanlægget kører nu er det med kosntant indblæsning. Derfor undersøges det om der er mulighed for at behovsregulere dette, og om der er besparelser at hente ved. Yderligere kigges der på udskiftning af nogle af de gamle komponenter til mere energirigtige komponenter. Der kigges til sidst på afkastluftens energiindhold, for at undersøge en eventuelt en varmepumpe kan implementeres.

 

Engelsk resumé:

This Bachelor project is a product of the final semester at Aarhus School of Marine and Technical engineering. During the internship at Glenco A/S, which is a cooling- and ventilation firm and part of the Kemp & Lauritzen corporation, I was able to use many theoretical skills from the past semesters and use them practically.

This report is dealing with energy optimization on the ventilation system connected to the pool area of Gellerupbadet. The energy optimization is necessary to determine whether Gellerupbadet can receive contribution from the government due to energy savings the optimizations will provide.

The ventilation system connected to the pool area of Gellerupbadet is an old system. Because of that Glenco A/S has reason to believe that Gellerupbadet could use much less energy than it does at the moment. The energy savings can be divided into two sections. The first section is exchanging the old components with new less energy consuming components. The second section is regulation of the airflow so that it meets the actual demands at the specific time of year and if Gellerupbadet is open or closed.

In order to determine the actual demand in given situations, the general demands to ventilation systems and the indoor air climate is found. The indoor climate in the pool area has to be comfortable for the paying visitors. A huge factor in this is to maintain an acceptable humidity and temperature which is the main task for the ventilation system.

To calculate the necessary airflow in certain situations like winter or summer, the evaporation of the pools has to be determined. That evaporation is what the airflow needs to remove from Gellerupbadet. In order to do that the humidity and the temperature of the fresh air is important because it influences its ability to obtain the evaporated water from the pools. The result is that different airflows is needed at a specific time a year and the water evaporation varies do to the usage of the pools. The energy savings is calculated by comparing the present energy consumptions with the attainable energy consumptions.      

In addition to regulating the airflow from the ventilation system the effects of changing some of the components will be calculated. With these calculations the energy savings due to the new components can be added to the savings from the airflow regulation. 

Furthermore this project determines whether heat pumps can be used on this ventilation system. The usage of heat pumps is for using even more energy of the outgoing airs energy. That is an advantage during the summer times, where the outside air already is hot and therefore don´t use much energy form the outgoing air.
