1. Part No. 1. Modernization of the heat source.1.1. Scope of work: 1) Ground heat pump. Ground heat pump: nominal power 35 kW, brine/water type, 2) Lower source. 8 vertical wells, 90 m each, total length 720 m, PE100-RC probe pipes 40 mm, double U, infill thermally conductive (silica bentonite), carrier: 30% propylene glycol solution, spacing between wells: approx. 8 m, in accordance with PZT, each well with shut-off and the possibility of flow balancing. 3) Distribution well. prefabricated PE, length 1200 mm, thickness 1.8 m, equipped with distributors and balancing valves. All work related to the lower source of the heat pump should be carried out in accordance with the guidelines of the manufacturer of the pipes used. The designed pipelines are run by, among others, 20-40 cm below the frost zone, the supply pipelines should be placed at a distance not less than 70-80 cm from each other and from other pipelines. In addition, special attention should be paid when filling the hole ring to ensure it is complete, without defects and gas spaces. The filling should be done with a liquid filling mass. Pipe purpose casing: inserting and routing the supply lines for the brine circuit (a pair of supply and return pipes...
