Calculation of comprehensive energy consumption for circulating water
Thread Content
Dear colleagues in this field, when calculating energy consumption, our circulating water is provided by another project. How should we account for the circulating water in such calculations? Do we need to consider both the input and output values? And what value should be used for the conversion factor?
The energy consumption of circulating water is divided into electrical energy consumption and fresh water energy consumption
GB/T 2589-2020 General Rules for Calculating Comprehensive Energy Consumption; SH/T 3110-2001 Methods for Calculating Energy Consumption in Petrochemical Design; GB/T 50441-2016 Standards for Calculating Energy Consumption in Petrochemical Design. The conversion factor for treated water is taken as that of \"fresh water\". The coefficient for converting the power consumption of the circulating water main pump and fans into an equivalent value is applied.
When calculating the comprehensive energy consumption of circulating water, it is usually necessary to consider the input and output energies. The specific calculation method is as follows: 1. Calculate the energy input required for the circulating water system: This includes the energy consumed in the supply or collection of circulating water, such as the energy used by water pumps and cooling equipment. 2. Calculate the energy consumption of the circulating water system: This includes the energy required for the use of circulating water, such as the energy used for cooling, heating, or other industrial processes. 3. Calculate the total energy consumption of the circulating water: By adding the input energy consumption and the output energy consumption, the total energy consumption of the circulating water can be obtained. As for the value of the discount coefficient, it is generally determined based on actual circumstances. Conversion factors are used to convert the energy consumption of different energy forms into standard units for comparison; common conversion factors include those for electrical energy and coal energy. The basis for determining the value can be industry-related standards or recommended values from references. In the absence of clear guidelines, it is possible to consult professional organizations or energy management experts to select an appropriate conversion factor based on the specific application area of the circulating water and the form of energy involved. .
Can we calculate how much energy goes in and how much energy goes out, with a coefficient for the energy difference?
