![]() City water systems should always include approved backflow prevention devices and open (air gap) drains. ![]() Water flow through the condenser is modulated by a control valve in the supply or discharge line, usually actuated from condenser head pressure to (1) maintain a constant condensing temperature with load variations and (2) close when the refrigeration compressor turns off. The return is run higher than the condenser so that the condenser is always full of water. ONCE-THROUGH CITY WATER SYSTEMS Figure 1 shows a water-cooled condenser using city water. ONDENSER water systems for refrigeration processes are classified as (1) once-through systems, such as city water systems or (2) recirculating or cooling tower systems. ![]() Overpressure due to Thermal Fluid Expansion. Low-Temperature (Water Economizer) Systems. CONDENSER WATER SYSTEMS Once-Through City Water Systems.
