Evaporative chiller unit

Evaporative chilled water unit is a high-efficiency refrigeration equipment developed based on the absorption of advanced heat exchange technology from abroad.
Integrating the traditional cooling water system with the unit condenser, utilizing the latent heat generated by the sprayed forest water on the surface of the coil to achieve heat exchange. It is currently an energy-saving device and also a trend in industry development. At present, it is widely used in the fields of chemical engineering, food, freezing, refrigeration, etc. Its significant advantages include low operating costs, significant energy-saving effects, an increase in efficiency of about 26% compared to traditional cooling water systems, and a water consumption savings of about 60%.
Comparison between water-cooled and evaporative cooling systems: (taking 1500KM freezer as an example)
1. More than 85% more energy-efficient than water-cooled systems. Eliminate the need for high-power cooling water pumps;
2. Save more than 30% in water system pipeline engineering and reduce on-site workload.
During high temperature operation, the cooling effect is improved by 15%
When operating in high ambient temperatures during summer, the evaporative cooling effect increases by 15%;
4. Never cause malfunctions due to low-temperature icing. At the same time, the water tower does not float water. Under low temperature conditions in winter, the evaporative pipeline will never fail due to freezing, and the water tower will not float during operation.
Evaporative condenser: The water, fluorine, and air heat exchange devices have excellent heat transfer effects.
Evaporative condenser is equivalent to traditional chiller shell tube condenser+cooling tower
The water pump, connecting water pipelines, and valves are integrated into one unit.
Operating principle

The high-temperature gaseous refrigerant inside the coil exchanges heat with the spray water and air outside the coil, and the refrigerant gradually condenses from a gaseous state to a liquid state. The super strong wind force of the induced draft fan completely covers the surface of the coil with sprayed water, and the heat transfer effect is significantly improved by the water taking advantage of the wind force. After the spray water and air absorb heat, the humidity increases, and some of the water changes from liquid to steam, evaporating and taking away a large amount of heat. The water in the hot air is intercepted by the water blocking plate and collected in the PVC heat exchange layer. The water in the PVC heat exchange layer is cooled by the flowing air, the temperature decreases, and enters the water collection tank. It is then pumped into the spray water system by the circulating water pump for further circulation. The water lost to the air is replenished by the water level regulator. The capacity of some devices can be controlled by different combinations of fan motors according to the load size.
