Basic school and nursery school, Lužná

The basic school and nursery school Lužná is located in the Lužná village in the vicinity of Rakovník - the county town. The building is surrounded by a large school garden with full-grown trees which offer pleasant shadow in summer.

In the building, there were installed three solid fuel boilers and a hot-water heating system with steel pipeline and steel sectional radiators. In the basement of the original building, there were installed three VSBIV boilers, each one with the output of 365 kW.

All parts of the building are heated by hot-water pressure-connected system from the solid fuel boiler room (located in the basement of the main building and connecting part) with a projected drop in temperature up to 90/70°C. There is an installation engine room in the boiler room, in which the heating water is divided into five main branches used for self-heating power of each of the main parts of the building. Using single spinal heating branches the heating water is distributed from the boiler room to the heating sections of the building located mainly in the basement. A secondary distributor of heating water was also fitted in for the distribution of hot water to the main part of the building - the extension with the school kitchen and dining room.

The purpose of the project was to install a new heating system including a heat source, a cascade of six air- water heat pumps with the total output of 198 kW (A2 / W50) with a dual-mode electric boiler with the output of 144 kW. Heat pumps SPLIT HP3AW36SB are formed by the outer and inner parts. Newly designed hot-water heating system with parameters for heat pump operation. The system will be connected to a steel panel radiators.
