Can a temperature control valve adjust the temperature of chilled water?
Thread Content
I’ve just started working in the chemical industry, and I have a problem: I need different outlet water temperatures. There is only one chiller available, and its outlet water temperature is -5°. Is there any way to achieve several different outlet water temperatures? -5° becomes 0°, 5°, -5°. Can a temperature control valve meet this requirement? I have no experience with temperature control valves.
There are temperature control valves that can keep the temperature below zero, and the temperature control range can also be adjusted; however, it should be difficult to use a single valve to control multiple temperature ranges at once
Are the temperature control valves used to regulate temperature and those used to control steam and hot water the same? Is there still a dedicated temperature control valve? It is controlled by different temperature control valves for diversion on the pipeline; one temperature control valve regulates the temperature in the branch pipe.
For this type of regulation, you still need a heat source; just using a valve alone is not sufficient to change the temperature
Yes, that’s possible; for example, I can use the return water from a chiller unit as a heat source to achieve mixed heating. Is the precision of temperature rise using a thermostatic valve high?
It’s possible to do it by adding a water tank and electric control valves; the piping system will also be more complex.
Is it ammonia or something else that is used in refrigerators?
Is it an electric control valve? Which type of control valve can still meet the requirements?
Chillers, with ethylene glycol as the refrigerant. Liquid ammonia is not needed. screw-type
If you have a gas supply, you can also use a pneumatic control valve to regulate the temperature! This should be a three-way valve! !
Adjustable valves can meet the requirements, but their stability is poor and the temperature deviation is significant; generally, a mixing tank is used to obtain cold water at the desired temperature
