Steel Structure Factory Cooling Solutions?

Factory buildings are typically categorized into brick-concrete structures and steel structures, with steel structures being the predominant type. During summer, cooling steel-framed metal-roofed factory buildings remains a persistent challenge for many factories. Traditional air conditioning proves prohibitively expensive, while roof insulation fails to address the root cause of high temperatures and yields limited results. Below are several practical ventilation and cooling solutions that can be combined based on specific factory conditions:

1. Natural Ventilation Solution

Roof Ventilators (Passive Ventilation Balls):

Install passive ventilation balls on the factory roof. These utilize thermal pressure differentials to automatically expel heat without electricity, offering low installation costs. They are suitable for assisting smoke and hot air exhaust, with particularly noticeable effects in high-temperature zones. Install operable windows or roll-up doors on both side walls to create air convection (through drafts). It is recommended to stagger window heights to enhance the upward expulsion of hot air.

2. Forced Ventilation Solution

(1) Install Negative Pressure Fans:

Negative pressure fans are energy-efficient, high-capacity ventilation devices that extract hot, stagnant air from the facility while introducing fresh, cool outdoor air for convective exchange.

(2) Install Exhaust Fans or Cooling Fans:

Install exhaust fans or cooling fans on roofs or walls to expel hot air while drawing in cooler air.

3. Integrated Cooling Solution

(1) Eco-Air Conditioner + Negative Pressure Fan:

Leveraging the exhaust characteristics of negative pressure fans, the system first expels existing hot, stuffy air from the interior. It then continuously delivers clean, cool air from the eco-air conditioner, forming a water-cooled fresh air positive pressure system.

(2) Eco-Air Conditioner + Industrial Fan:

Combine two distinct advantages in factory cooling equipment: evaporative eco-air conditioners and industrial fans. The air conditioner directly delivers a steady stream of clean, cool fresh air into the workshop, while the industrial fan’s three-dimensional micro-air circulation system ensures even distribution of cool air throughout the space.
