Today, when rising energy costs have become one of the biggest expense items, it is a system that will encourage efficient use of energy and ensure that everyone who complies with applicable laws and regulations pays only as much as they use.
The single-column calorimeter (heat meter) (new buildings) is also the device from which only the first data is received for the allocation of heat costs.
According to the “Energy Efficiency Law” No. 5267 and Regulation No. 26847, in buildings with central or regional heating systems and sanitary hot water systems with more than one independent section to be built, it is to determine the procedures and principles for distributing heating and sanitary hot water expenses to the users of the independent sections.
The heat costs of
According to the regulation; central heating systems are divided according to the following calculations.
Calculation in the case of using heat meters:
P1 = 0.70 x M x (S1/St+ S2/St+S3/St+... Sn/St)
P2 = 0.30 x M x (A1/At)
P = P1 + P2
M: Total heat consumption of the building (TL)
P: Total consumption amount of the independent part (TL)
P1: Consumption amount according to the heat meter of the independent section (TL)
P2: Common consumption amount of the independent part (TL)
Q: The value read on the heat meter located in the independent section (TL)
St: The sum of the values read from the heat meters in all independent sections of the building
A: Closed use area of independent section (m2)
Horse: Total enclosed areas of use of independent sections in the building (m2)
Total sanitary hot water expenses in centralized sanitary hot water systems are distributed according to the measured hot water consumption of users.
The allocation of hot water expenses in centralized hot water systems is implemented as follows.
a) Calculation if the heating system that provides hot water production is independent of the central heating system and hot water meters are used :
P1=0.80xMX (S/St) P2 = 0.20xmx (A/At) P = P1 + P2
M: Total heat consumption of the building (TL)P: Total consumption amount of the independent part (TL)
P1: Consumption amount according to the heat meter of the independent section (TL)
P2: Common consumption amount of the independent part (TL)
Q: The value read on the heat meter located in the independent section (TL)
St: The sum of the values read from the heat meters in all independent sections of the building
A: Closed use area of independent section (m2)
Horse: Total enclosed areas of use of independent sections in the building (m2)
b) In the calculation of the total sanitary hot water consumption cost of the building (M), the heating system providing the production of sanitary hot water is dependent on the central heating system; the share of the central heating system is the total amount of consumption remaining after the consumption of the central sanitary hot water system is deducted.
The amount of fuel consumption (By) of the central sanitary hot water system is calculated in terms of By=1.20xVx (tw-10) Hu.
In this case, the total amount of sanitary hot water consumption of the building is calculated (M); M= By x F (TL). Here;
F: Fuel unit price (TL)
By: The amount of central hot water fuel consumption (taken in kg for solid and liquid fuels, m3 for gas fuels.)
M: Total hot water consumption of the building (TL)
V: Volume of hot water consumed (Lt)
tw: hot water temperature (°C)
Hu: Lower thermal value of fuel consumed (kcal/kg for solid and liquid fuels, Hu values in kcal/m3 for gas fuels are taken from fuel supplying organizations.)
It is a system that saves managers in this way from complex calculation and reading meters by eye by entering circles.
