How to estimate the water consumption of a water cooler?
Thread Content
Our factory’s water coolers do not have any measurement of water consumption; I would like to ask how to estimate the water usage of these coolers?
It is best to include a meter; in the absence of one, estimates must be made using the heat balance equation. For this purpose, it is necessary to know the temperature of the hot and cold streams at each stage, the heat transfer coefficients, the fouling thermal resistance, as well as the heat flow rate or heat exchange area
This is very simple. The water consumption of a water cooler can be estimated without the need for highly precise instruments. First, it is necessary to know the inlet temperature and outlet temperature of the circulating water. Based on thermal equilibrium, the total heat amount can be determined using the medium on the hot side, and from this the flow rate of water in the cycle can be calculated. With the amount of circulating water, and based on the waste discharge volume of the plant, the water consumption can be determined.
