Ventilation syste with heat recovery in public sport centre

Investment relate to Pilot Action. German parnter installed a ventilation system with a heat recovery system in a public owned sports centre. It has a ground space of 633 m², air volume of 7.500m³, current demand of 4.900 kWh/a and heat energy demand of 64.000 kWh/a. It was heated by a gas heating system and it was under partially utilization as requested by the schools and the other users during the week. The pilot investment consists of the ventilation system with an heat exchanger for reducing the energy losses between the warm interior air and cold exterior air during the ventilation process. The heat recovery ventilation system (HRV) is established as stand-alone device that operate indecently or part of an existing heat-ventilation and air condition system. The HRV technology is designed as rotation or plate heat exchanger with an air to-air or earth-to-air systems.
Heat exchange is managed by different flow arrangements: (parallel flow, counter flow, cross-flow)

The concrete technology was researched and planned within the pre-investment concept and the dimension of the system is depending on the DIN18032-1 as regulation for planning “sport centres - halls and rooms with multi-purpose use”. Further it was depending on the current activities carried out by the city for improving the energy efficiency of the sports centre by renewing the heating system to a gas condensing technology system, thermal insulation of the external walls and renewing the floor with a thermal insulation towards the soil.
