The compressor discharge line contains a purge valve at the high point and a service valve. single condenser illustrated in Figure 3. After the water has been chilled, it is distributed via pumps, pipes, and valves (the distribution system) to the loads, where a heat exchanger—for example, a cooling coil in an air-handler—transfers heat from the air to the chilled There is a thin water film around the condenser tubes from which evaporative A typical one usually contains a hot primary coolant, a cold primary coolant, water sprinkles, cold water, and centrifugal fan in order for the system to provide the desired outcome. For most industrial manufacturing, electric power generation and even air-conditioning needs, cooling towers are a critical element of the design. 5. It also allows malfunctions or reductions in efficiency to be identified, particularly if the water make-up consumption is plotted on a graph. As the refrigerant passes through the compressor to the condenser, the pressure on the refrigerant raises its temperature to 100 F, causing condensation in the condenser coil, finally, the unwanted heat is released into the atmosphere with the help of a fan. The methods, analysis, and results presented in this paper focus on evaporative condenser sizing and head pressure control. Note trap in liquid line and equalizer from top of receiver to hot gas line. The refrigerant piping is tied into the condenser and water is distributed over the pipes directly.

Evaporative cooling is the process where warm water from an industrial process is pumped up to the top of the cooling tower where the water distribution system is. The methods, analysis, and results presented in this paper focus on evaporative condenser sizing and head pressure control. The evaporative condensing apparatus is based on the rule that the relative critical pressure needed to condense a cooling medium is directly proportional to the temperature during the exchange of a cooling medium between gas state and liquid state. It also allows malfunctions or reductions in efficiency to be identified, particularly if the water make-up consumption is plotted on a graph.
