District cooling plant for energy provider in Jyväskylä, Finland

A new ice arena containing two ice rinks has recently been completed as part of the extension of the Buugi recreation and fitness center in the city of Jyväskylä, Finland. The amount of cooling energy required by the arena is produced by means of district cooling plant located in technical container owned by local energy provider and manufactured by Suomen Tekojää Oy.

Brine cooled freon refrigeration equipment with cooling capacity of 580 kW and R407F as a refrigerant is located on the ground floor of two-level technical container located just outside the arena. Condensing heat released from the equipment is recovered to be transferred to the facility heating network as well as to the heating coil of arena air handling unit located on the upper floor of the technical container. The refrigeration equipment is designed to provide cooling energy for ice rinks of the arena as well as to ensure air conditioning of personnel and public premises of the fitness center by means of ventilation systems.

New refrigeration equipment for skating center in Seinäjoki

Recently renovated skating center in Seinäjoki has now three ice arenas and a large ice rink with 400 m speed skating track. Refrigeration equipment of large ice rink, existing ice arena and new ice arena built to replace former outdoor ice hockey rink has been renovated as part of recently completed project.

Scope of works performed by Suomen Tekojää Oy included dismantling of existing refrigeration equipment, engineering of new refrigeration units, installation and commissioning on turnkey basis as well as replacement of ice rink slab cooling pipeline and transit brine pipeline in new ice arena built to replace former outdoor ice hockey rink. New state-of-the-art remote controlled ammonia refrigeration equipment has been installed in existing refrigeration plant room. Total cooling capacity of the equipment is divided to provide 2 MW for the large ice rink and 500 kW for two ice arenas. A condensing heat pump unit with heating capacity of 630 kW is installed in the same plant room with the refrigeration equipment. The unit is designed to heat water up to 60oC for further use in radiator heating and domestic hot water systems of the skating center.

Mobile refrigeration unit for Kuopion Energia

We have manufactured a mobile refrigeration unit with cooling capacity of 1,6 MW by order of local energy company Kuopion Energia.
