AI Technical Summary

Technical Problem

Existing chiller units may experience a temperature drop below the start-up threshold due to natural cooling or excessive heat dissipation from the cooling tower when the ambient temperature is below 10°C, triggering a protective shutdown and affecting the production of the pharmaceutical production line.

Method used

By introducing a chilled water pump and an air conditioning surface cooler into the cooling unit, low-temperature cooling water is used for circulating cooling, and the cooling water is recycled through valve switching. Combined with a support structure, the pipe connections are secured to prevent loosening.

Benefits of technology

In cold environments, the system achieves cooling water circulation and cooling, saving the electricity and water required to start the compressor, avoiding production interruptions, and using a support structure to secure pipe connections and prevent loosening.

Abstract

This utility model relates to the technical field of cooling units for pharmaceutical production lines, specifically to a cooling unit for pharmaceutical production lines, including a cooling tower and a cooling unit. The cooling unit is connected to a cooling pump via pipes. When the ambient temperature is below 10 degrees Celsius, the cooling water may cool to a temperature below the cooling unit's start-up threshold due to natural cooling or excessive heat dissipation from the cooling tower, triggering a protective shutdown. The cooling pump, the first valve, and the third valve can be closed, while the second valve and the fourth valve can be opened. Cooling water is then drawn by the chilled water pump and supplied to the air conditioning surface cooler. The cooling water is then returned to the cooling tower via the fourth pipe. In cold winters, low-temperature cooling water can be used for circulating cooling, saving energy for compressor startup and water consumption. The valves are easy to switch and operate, and the water purification device can use a pre-filter for the pipeline to filter impurities and prevent damage to the chiller and surface cooler by the cooling water.
