For a central chilled water plant, Section 6.4.3.11 provides requirements for data collection and trending requirements of chiller plant energy use and efficiency. The prescriptive compliance path of ASHRAE 90.1-2019 (Section 6.5.1) requires the use of an air economizer, fluid economizer or a condenser heat recovery system.

The evaporator uses the heat from the chilled water to boil the liquid refrigerant contained within the evaporator. As the refrigerant evaporates, the cooling water is cooled (evaporative cooling). Evaporator. The evaporator is a shell and tube heat exchanger. Liquid refrigerant submerges the tubes and is referred to as the ''shell side'' fluid.
If the water temperature is too high or too low, your plants will either grow too fast or too slow, affecting their quality and yield. The ideal water temperature for most hydroponic plants is between 65°F and 75°F. However, this may vary depending on the type of plants, the stage of growth, and the ambient temperature.
