The relationship between heat transfer capacity and energy consumption
Thread Content
I would like to ask here: if the heat exchange capacity Q of a heat exchanger increases, with Q being measured in kilocalories, and kilocalories can be converted into efficiency values, then for an entire system, how is the actual electricity cost saved as a result of an increased heat exchange capacity of the heat exchanger reflected?
An improved heat exchange efficiency in the heat exchanger definitely leads to energy savings, there’s no doubt about that. The key question is how to calculate the electricity costs

For example, if the increased power is P = 12 kW, then the amount of electricity saved over a period of T = 24 hours, that is, in 1 day, is P × T = 12 × 24 = 288 kW·h, which is equivalent to 288 units of electricity. If this heat is generated by electric heating. As for how much the electricity cost is, it’s not difficult to calculate. Is this middle school physics?
Not all energy consumption can be converted into electrical energy; for example, different power generation units have varying coal consumption rates, and there are different conversion coefficients for this
Energy savings can be converted into coal consumption and fuel consumption, and then the corresponding prices are taken into account.
If using electric heating can indeed help save on electricity costs, then checking the electricity meter will show that
It’s about energy savings in chemical processing units. Our plan is to improve the thermal efficiency of the heat exchangers; an increase in thermal efficiency certainly leads to energy savings for the system. Thermal efficiency can be expressed in terms of KW, but it’s not clear whether these KW values refer to the energy consumption of the entire system
It is about saving energy in the circulating water of chemical plants; how can one calculate the amount of energy saved?
