Cooling adjustment of the water cooler
Thread Content
When adjusting the cooling capacity of the on-site water cooler, everyone opens the inlet valve fully – should the outlet valve opening be adjusted as well, or should the inlet valve opening be adjusted while keeping the outlet valve fully open? I’ve seen both methods used on different devices, and I think it’s better to keep the inlet valve fully open. What do you think?
Valves are generally present for both import and export flows. The inlet valve should be kept fully open, while the outlet valve is used to regulate the temperature; this is mainly done for safety purposes, to ensure that the equipment is filled with water, and to prevent accidental closure of the inlet valve.
It’s sufficient to control the outlet valve; closing it partially is not only unsafe but also unnecessary.
I don’t understand what’s unsafe about closing the small outlet valve; could the colleague on the third floor explain?
There are advantages and disadvantages to installing control valves before and after the cooler. Installed at the back, with the inlet valve fully open, this allows the liquid to fill the cooler, preventing accidental closure of the inlet valve. However, the cooler is under high pressure, which is detrimental to the equipment.
Generally, open the inlet valve fully, adjust the outlet valve, extend the heat exchange time, and improve the heat exchange efficiency； Flow measurement is at the inlet.
Generally, the inlet valve is fully open, while the outlet is a control valve used to regulate the flow rate. Basically, it works like this: if the inlet is a control valve and the process requires the valve to be closed, then the water temperature in the cooler rises; without any supplementary water, microorganisms die easily, scaling occurs frequently, and the efficiency of the heat exchanger is greatly reduced. Regarding pressure issues, a safety valve is installed at the cooling water outlet to protect the equipment.
