Because the floor heating capacity of the floor heating system is large, the system temperature stability
is greatly guaranteed, and this point can be ignored.
For commercial water system design, it should be checked whether the water capacity of the calculation
system meets the thermal stability requirements of the system. When the actual water capacity of the
system cannot meet the requirements, the main pipe diameter of the system or a new water storage tank
should be added. It is not means that the greater the water capacity of the system, the better the water
capacity is. The water capacity is too large, and its thermal stability is undoubtedly good. However, after
a long time of shutdown, time for pre-cooled or warm-up of the air conditioner will be extend.
The water capacity of the system can be calculated as follows:
V=P×T/
（ C×Δt ）
V: system minimum (large) water capacity, kg (unit), 1 kg =1 L.
P: the heat dissipation power of the terminal of the unit, it can be calculated according to the rated
cooling capacity of the host, W(unit).
T: Minimum (large) requirement for stability, S (unit);
C: Specific heat of water, 4200J/kg·°C;
Δt: The fluctuation of water temperature requirements, it can be referenced by 5K.
