S43 -- Liquid-Chilling Systems (I-P)

Liquid-chilling systems cool water, brine, or other secondary coolant for air conditioning or refrigeration. The chiller maybe either factory-assembled and wired or shipped in sections for erection in the field. The most frequent application is water chilling for air conditioning, although brine cooling for low-temperature refrigeration and chilling fluids in industrial processes are also common. For information on absorption equipment, see Chapter 18 of the 2022 ASHRAE Handbook -- Refrigeration.
