AI Technical Summary

⚠Technical Problem

The cooling capacity of natural water in dairy production parks is not being fully utilized, resulting in resource waste.

⚗Method used

Design a chilled water system that combines a water storage container and a cooling tower. The system uses the lower-temperature natural water in the water storage container to cool the chiller unit and uses the mechanical ventilation of the cooling tower to further reduce the required cooling tower capacity, thus achieving combined cooling from multiple cooling sources.

🎯Benefits of technology

It improves the operational stability and energy efficiency of the chilled water system, reduces initial equipment investment, makes full use of the cooling capacity of natural water, and reduces the configuration requirements of cooling towers.

Abstract

The present disclosure relates to a chilled water system, comprising: a chiller unit comprising a freezing side and a cooling side, the freezing side being configured to provide chilled water to a user side; a cooling tower connected to the cooling side of the chiller unit; and a water storage container connected to the cooling side of the chiller unit, the water storage container being configured to contain natural water; wherein at least one of the cooling tower and the water storage container is configured to operatively provide cooling capacity to the cooling side of the chiller unit. The chiller unit is cooled by the cooling capacity of the lower temperature natural water in the water storage container, and the mechanical ventilation cooling of the cooling tower is used to take away the heat emitted by the condenser in the chiller unit, thereby reducing the selection capacity of the cooling tower, reducing the initial investment of the equipment, and improving the operation stability of the chilled water system by using multiple cooling sources for joint cooling.
