Project description:

The heating system consists of radiator heating, air curtains and heating via air conditioning heater. The heating source is "Shell And Tube" heat exchanger (steam / water) type 9B-I NIRO-Pireko, steam 6 bar / hot water 90/70 ° C, heat output Q = 3435 kW. As part of the project, a new thermal substation with 3 heating circuits (radiator heating, air conditioning chamber, air curtains) was built. The heating system is regulated by an automatic control system. Cooling of the building was performed through: VRF system (as a heat pump); air-to-air divided into 5 outdoor units and 65 indoor units located in the ceiling of the building with a total power of 123 kW
Air conditioning and water cooler system (2 pcs., 170.45 kW and 27.21 kW)
The ventilation system consists of 6 separate air chamber systems:
  • K-1 – 5.900 m3/h
  • K-2 – 4.200 m3/h
  • K-3 – 3.200 m3/h
  • K-4 – 4.500 m3/h
  • K-5 – 2.700 m3/h
  • K-6 – 3.200 m3/h
