Calculation of heat transfer
Thread Content
Hello everyone! Please don’t laugh at me – I’ve never done such calculations before, so it might be quite simple. Could anyone help me estimate the value? I’d be extremely grateful! The conditions are as follows: fins (iron sheets) are added to the outside of the existing radiators to improve their heat dissipation capabilities. The additional area is 5.7 square meters, the inlet water temperature is 25 degrees, and I want to know what the outlet water temperature will be. The outdoor air temperature is assumed to be -4 degrees during the day. The water used is industrial circulating cooling water.
The heat required for the radiators is calculated based on the floor area; assuming that the indoor temperature rises from -4 degrees to 20 degrees, the heat needed is equal to the heat transferred by the circulating water. Due to insufficient data, only the approach can be described
