| Hankinnan lyhyt kuvaus | The Contracting unit is planning to implement air-to-water-heat pump- plant (AWHP) to Helsinki, Salmisaari. AWHP plant will produce heating and cooling to Helen's district heating (DH) and district cooling (DC) networks. AWHP plant is an air-source-heat pump system consisting of two main components: outdoor installed heat collectors and indoor installed DH supplying water-to-water heat pump units. Indoor heat pump units are installed into separate engine room (two storeys high). Heat collectors are installed to the roof of engine room. Outdoor installed heat collectors provide heat to an intermediate fluid network. Indoor installed heat pump units take heat from the intermediate fluid network and supply heat to the DH network. In this procurement The Contracting unit is seeking a supplier for outdoor installed heat collector setup including all the necessary auxiliaries, accessories and services within the delivery limits (commissioning, necessary training etc.). Installation work (connections to The Client's pipe networks) including lifting the heat collectors to the roof are not included to scope of supply, but can be offered as an option. Each heat collector shall be capable to operate independently. The heat collectors heat the heat transfer fluid in intermediate network. Heat transfer fluid enters the heat collector, ambient air is drawn with fans and blown through heat collector fins. Heat transfer fluid gets warmer while flowing through the collector piping and then exits the heat collector. Key requirements of the heat collector setup and general conditions: - As high total capacity from heat collectors to intermediate fluid network as possible, however min. 6000 kW when ambient temperature is 0 °C and relative humidity is 75 % - Air flow direction is downwards. - Electrical supply to a heat collector unit is 400 V, 50 Hz. - Heat collectors must withstand local ambient conditions in Helsinki (snow, ambient temperature -30…+35 °C). The heat collectors will be installed on the roof of a building. A steel frame foundation, which is elevated approximately 3,5 meters from roof surface, will be constructed by The Client. Elevation of the foundation top level is approximately +21 meters above sea level. Ground level is at +3 meters. Dimensions of the installation area is approximately 40m X 14m. Individual heat collectors are installed next to each other so that no air recirculation between heat collectors occur. The preliminary scope of supply is described more accurately in the initial RFT and in its Annexes. |
