Where should the water inlet be located on condenser and evaporator piping of chiller equipment?

In chiller equipment, the water inlet should be located at the top of the evaporator, often referred to as the cooler. This design facilitates the effective circulation of water through the system. When water enters from the top, it allows for the proper flow and distribution of water over the evaporator coils or tubes, optimizing the heat exchange process.

As the water absorbs heat from the refrigerant during the evaporation process, it becomes warmer and subsequently rises, allowing for a more uniform flow and preventing issues such as dead spots where inadequate heat exchange might occur. This orientation enhances the efficiency and performance of the cooling system.

In contrast, positioning the water inlet at the bottom would not support optimal fluid dynamics within the evaporator, which could lead to reduced efficiency and potential issues with the operation of the chiller. Therefore, placing the water inlet at the top aligns with the engineering principles aimed at maximizing heat transfer and overall system efficiency.
