Which type of temperature regulating valve is used where chilled water is the primary cooling medium in the heat exchanger?

A two-way temperature regulating valve is used where chilled water serves as the primary cooling medium in a heat exchanger because it efficiently controls the flow of water in response to temperature changes in the system. This type of valve alters the flow rate of chilled water entering the heat exchanger based on the temperature demands, effectively optimizing the cooling process by ensuring that the heat exchanger operates within its desired temperature range.

As the temperature of the medium being cooled changes, the two-way valve opens or closes to adjust the flow accordingly, offering a straightforward and effective means of temperature regulation. This makes it ideal for applications where precise control over the cooling medium is necessary to maintain desired temperature thresholds.

In contrast, other types of valves, such as three-way valves, are designed for mixing or diverting flows and would not be the best fit for a situation focused solely on regulating the flow of a single cooling medium like chilled water. Single-point valves and flow-control valves serve different purposes that are not aligned with the effectiveness needed in a heat exchange system utilizing chilled water.
