For most industrial manufacturing, electric power generation and even air-conditioning needs, cooling towers are a critical element of the design. 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. Evaporative processes lead to the A two-stage compressor using ammonia is to operate with an evaporative pressure (EP), interstage pressure (IP), and condenser pressure (CP). The refrigerant piping is tied into the condenser and water is distributed over the pipes directly.
