industrial refrigeration and air conditioning systems. These systems use the evaporative cooling method, in which refrigerant loses heat as it passes through water-sprayed condenser coils. However, these condensers lose heat, water, energy, and hydraulic fluid. This project intends to improve water quality in condensers and cooling towers by using ETP water, constructing DM plants, and optimizing the heat exchange process in order to increase overall efficiency and save costs.

1. INTRODUCTION
1.3 Objective
Evaporative condensers are commonly used in industrial refrigeration and air conditioning systems to reject heat to the atmosphere by utilizing the principle of evaporative cooling. In such systems, the refrigerant releases heat while passing through the condenser coils, which are sprayed with water to assist in heat dissipation. The process relies on the evaporation of water, where part of the water evaporates as it absorbs heat from the refrigerant, thus enhancing the cooling efficiency. However, despite their efficiency, evaporative condensers are subject to several types of losses that can affect overall system performance.
Analyze the benefits of evaporative condensers over traditional air-cooled systems.
