Beverage Production Workshop Cooling and Ventilation Project

Project Overview

This project addresses cooling challenges in a beverage packaging workshop by proposing a high-efficiency, energy-saving solution. The semi-open workshop features a large, decentralized layout that impedes natural ventilation. Primary heat sources include thermal radiation from equipment such as filling and sterilization systems, combined with heat generated by worker activity, creating an uneven high-temperature environment. Traditional air conditioning systems perform poorly in such settings due to inefficiency and high energy consumption. Evaporative cooling technology, however, effectively resolves complex heat load issues while drastically reducing energy usage, making it the ideal cooling solution.

Operational Design

The system employs 49 Aolan Duo-series evaporative air coolers installed across the 1st to 4th floors, covering the packaging workshop, palletizing workshop, and air compressor room. Cooling strategies are tailored to each area based on operational characteristics and heat output:

· Packaging Workshop: Full-space cooling.

· Palletizing Workshop: Targeted cooling for specific workstations.

· Air Compressor Room: Zonal ventilation cooling.

Each cooling zone utilizes positive-pressure air supply from the coolers, paired with negative-pressure exhaust fans to rapidly expel heat, ensuring efficient thermal management.

Performance Results

The semi-open workshop design incorporates seasonal operational optimization: evaporative cooling (wet mode) is activated in spring, summer, and autumn, while the system remains idle during winter. Since its commissioning in 2024, the equipment has demonstrated stable operation and exceptional performance following system debugging and optimization. Field measurements confirm that the air outlet temperature of the coolers is consistently maintained at 26–30°C, with an 8–10°C temperature reduction in operational areas. All indicators meet predefined targets, achieving significant energy savings and operational efficiency.
