Evaporative condensers use the cooling effect of evaporation to improve the heat rejection process. Water is sprayed over the condensing coil from above while air is simultaneously blown up through the coil from below to naturally lower the condensing temperature.
The lower condensing temperature reduces the compressor workload. As a result, your system operates more efficiently and uses far less energy than air cooled alternatives. Evaporative condensing and our unique evaporative condenser design offers a number of benefits, including:. Environmental sustainability. In general cooling tower is designed for Deg C approach and cooling water is pumped to the condenser with a typical difference of 5 Deg C of inlet and outlet cooling water temperature.
For understanding cooling tower approach, click here. Approach in condenser Condensation temp of liquid — Cooling water return temperature typically lies from Deg C. A Cooling tower, Pump and piplines are required for perform task of cooling in refrigeration system.
This complete process of cooling tower,pumping and condensation can be integrated to evaporative condenser,. The evaporative condenser is essentially a combination of a water-cooled condenser and an air-cooled condenser, utilizing the principle of heat rejection by the evaporation of water into an air stream traveling across the condensing coil.
Evaporative condensers can be designed to operate refrigerants condensation point to Deg C above wet bulb temperature. This cooling system is based on the same physical principle as the cooling towers. The main difference is that in a cooling tower the thermal exchange takes place in the filling and in the condenser in the tubular bundle through which the water or fluid to be cooled circulates. The refrigerant to be condensed enters the upper collector of the coil.
This is constantly moistened with water that recirculates in the evaporative circuit of the equipment. The evaporation of a fraction of water in recirculation removes the heat from the exchange surface of the coil.
The yield will depend on the ambient temperature of the wet bulb. The evaporating water of the condensers changes its chemical composition and His properties.
Therefore, it is important to analyze the water supply to apply the appropriate treatment to the materials. In this way, we will avoid incrustations that can lower the performance of the evaporative condenser. Therefore, it is best to choose anti-corrosion materials, light structures and easily removable. These measures will reduce the costs and time allocated to inspection and maintenance tasks.
