Re: Clarifications of the HVAC Final Design
Kindergarten and Nursery, Block V, Podgorica


Answers and clarifications of some concepts from the HVAC Final design - Kindergarten and Nursery, Block V, Podgorica will follow the original sequence of questions:

1. Heat capacity of 400 kW refers to one heating unit, hence the total heat consumption is Q = 2x400kW 800 kW.
2. Hot sanitary (consuming) water (60o) is provided by virtue of hot water from boilers (90/70oC) over winter, and by virtue of electrical heaters over summer when the boilers are out of function.
3. The Designer in Charge is not familiar with the equipment unit prices you dispose of.
9. Ducts in kitchen are used only for supply of fresh air, while the polluted air is exhausted separately.
10. The same as for Item 3.
11. The designed concept assumes supply of fresh air and exhaust of polluted air in/from the
kitchen and the laundry
