    New refrigeration, heat recovery and ventilation equipment for ice arena in Kuortane

    Suomen Tekojää Oy contracted to renovate HVAC-systems of ice arena of sports college in Kuortane, Finland. Existing refrigeration and ventilation equipment of the arena has been replaced with a new state-of-the-art totally remote-controlled unit placed inside an outdoor free-standing technical container. Ammonia refrigeration equipment with cooling capacity of 580 kW and condensation heat pump unit with heating capacity of 200 kW are both placed on the lower level of the technical container. Air handling unit of the arena is placed on the upper level and liquid cooler is mounted on the roof of the container. Condensation heat generated by the refrigeration equipment is recovered and utilized in air handling unit coils and in different heating circuits of the arena by means of the heat pump.

    The biggest challenge of this large-scale project was that the ice rink had to stay available throughout the renovation work. Proper timing of installation works and work stages helped us to handle the challenge successfully hence replacing the existing systems with new ones has been carried out smoothly.
