We were tasked with optimising the costs of heating, ventilation and air conditioning for a shopping centre in conditions ranging from -60 °C in winter to +39 °C in summer.
Thanks to the high competence of the design institute, our engineers, the capabilities of our plant, modern building materials and technologies, the solution was to implement air heating for the entire shopping centre as the most cost-effective option. The air is heated by gas heaters based on Weishaupt burners with smooth performance control. The ventilation units are specially designed for the compact dimensions of the ventilation chamber, and air treatment at temperatures of -60 °C has been made possible by the use of specially developed panels and profiles with no thermal bridges.
The refrigeration units also have a number of design features. The low-temperature kit eliminates the need for special winter maintenance, and each unit is equipped with a compact electric heater that maintains acceptable temperatures in the module containing the main components of the refrigeration circuit c.
Total project indicators:
- totalventilation unit capacity 220,000 m3/h
- totalcooling capacity of compressor-condenser units 450 kW
- totalcapacity of gas heaters over 2,700 kW, total consumption of about 300 m³/h.
The shopping centre is currently preparing for its opening, and a competition is being held to choose the best name for it.
