How to calculate the heat supply for hot water in storage tanks?
Thread Content
As stated in the title, the freezing point of the medium stored in the tanks in this tank area is 52 degrees. Hot water is used for heating; it’s a tank with a capacity of around 200 cubic meters, and heating is provided using hot water at 0.4 MPa and a temperature of 90 degrees. The temperature of the medium inside the tank rises to 60 degrees as a result. How should the amount of hot water required be calculated? External coil heating is being used; I would like to ask the experts here, or know which standard provides the calculation method for this:)
If heat dissipation is due solely to the air, then only the heat carried away by the balanced air needs to be considered.
Thank you for your reply. I would like to ask how to calculate it specifically; I’ve never done this before
Heat loss from the tank wall: Heat loss from the tank wall = heat transfer coefficient for heat loss * external surface area of the tank wall * (outer wall temperature of the tank wall – ambient temperature). Heat loss from the tank top: Heat loss from the tank top = Heat transfer coefficient of the tank top * Surface area of the tank top * (Outer wall temperature of the tank wall – Ambient temperature). Heat loss from the bottom of the tank: Heat loss from the bottom of the tank = Heat transfer coefficient of the bottom of the tank * Surface area of the top of the tank * (Outer wall temperature of the tank walls – Surface temperature during the coldest month in the area where the tank is located). Total heat loss of the storage tank: Total heat loss of the storage tank = Heat loss from the tank walls + Heat loss from the tank top + Heat loss from the tank bottom. This is what I found; I’m not sure if it will be helpful to you
Thank you very much. I was wondering where it was found – is it standard or not?
Take a look at the one found on Baidu Wenku: https://wenku.baidu.com/view/b60e7ccb0740be1e650e9adc.html
