In the main building “B” NURE with a standard load of 4.8 Gcal/h operates a modernized central heating and hot water supply. The payback period of the equipment was 1 thermal season and 2 months of the next (8 months of operation) with savings of 25-30% of coolant consumption. These indicators and a significant improvement in the quality of heat supply were achieved due to the introduction of a set of advanced technical solutions in the field of heat supply, namely:
- application of an independent heat supply scheme with forced circulation, which gives an even distribution of thermal energy between consumers in the system without overheating and cooling;
- the use of efficient high-speed plate heat exchangers Alfa Laval at the entrance to the independent circuit, which ensures minimal heat loss during transportation to consumers (≈1%);
- thermal insulation of the pipe system;
- introduction of high-quality weather-dependent regulation in the heating system, which ensures the optimal consumption of the coolant when performing the temperature schedule of the coolant supply;
- introduction of a modern group control system for efficient Wilo circulating pumps with the possibility of changing the circulation speed and organizing a schedule of switching within the group;
- modernization of the alarm system.
