Hospitals need uninterrupted electricity, heating and cooling energy for 24 hours. Power must be supplied without interruption at critical points of the hospitals. In addition to uninterrupted power, maintaining the ambient temperature at a required level at critical places such as operation rooms is also vital in terms of human health. 860 kW trigenerationsystem, which was designed and installed by TEKSAN, meets up to 50% of the electricity and about 75% of the heating demand of Edirne Sultan Murat I State Hospital.
In Edirne Sultan Murat I State Hospital 2x430 kW natural gas trigeneration system was installed. New hospital building, whose construction was completed in September 2015, was commissioned in September 28, 2015 and opened with a ceremony held on October 9, 2015. This hospital located at the entrance of Edirne province while coming from Istanbul is the biggest hospital of Edirne.
Absorption chiller that was commissioned to support the 7-12°C cooling line of the hospital in summer time, in-between May and September, and deliver 675 kW extra cooling capacity in addition to the electricity and heating provided for the facility.
2 units of 430 kWetrigeneration system that was used in this project, has thermal efficiency of 48%, electric efficiency of 38% and total efficiency up to 86%. The model with high thermal efficiency has been selected as it is an hospital application where hot water consumption and need is high.
The most important points of this project, is the fact that it is the first hospital trigeneration project which has been designed and commissioned by Turkey’s Ministry of Health and it is also the first domestic hospital trigeneration project realized in Turkey.
It has been observed that the trigeneration system has reduced the electricity bills by less than half within its running time. In addition, due to the heat produced by trigeneration system, hospital does not need to use 2 out of 3 units of 2500 kW boilers in the boiler room for heating the facility.
Thus, significant savings were realized in natural gas and electricity. According to the feasibility studied after system started to operate, it has been observed that the trigeneration system has provided monthly average saving of 70.000 TL to the hospital for 5 month-operation.
As it can be seen from the numerical data, implementation of trigeneration systems in hospitals contributes to the energy efficiency of the facilities and significantly reduces energy costs. Using energy in the most efficient way is always valuable and important for the facilities which need continuous energy such as sanitary facilities. On the other hand, to benefit from shorter return on investment periods could only be possible through affordable products with longer life span which have well calculated feasibility and accurate designs.
