As part of the vapor-compression cycle for mechanical refrigeration, the heat of compression produced must be rejected to complete the refrigeration cycle. Refrigerant systems may be cooled by air or water. In water-cooled systems, water flows through the condenser and is called condenser water. Condenser water systems are classified as (1) once-through systems (e.g., city water, well-water, or lake/groundwater systems), or (2) recirculating or cooling tower systems. This chapter focuses on open condenser water systems and evaporative coolers; for information on closed-loop systems used in ground-source heat pump loops, see Chapter 49 of this volume and Chapter 34 of the 2015 ASHRAE Handbook—HVAC Applications.
