A customer inquired.What is the best central air conditioning solution for a 5,000-square-meter mold production workshop? I need to carefully analyze this issue and provide an appropriate solution.

Mold workshops typically feature spacious layouts with high ceilings, numerous machinery, and significant heat generation. They may also have issues like dust and oil mist. Therefore, the air conditioning system must not only cool down the space but also ensure ventilation, filtration, and humidity control. Additionally, different areas within the production process may have varying temperature requirements, such as separate controls for office and production zones.

One,Central Air Conditioning System Types

Common types include multi-axis machines.VRV systems, water-cooled chillers, air-cooled modular units, and ground-source/ground-water heat pumps, possibly integrated with air supply or purification systems. It is necessary to compare their pros and cons, as well as their applicable scenarios.

The multi-machine system is highly flexible, allowing for zonal control and easy installation. However, it may require a high initial investment for large-scale workshops, and if the workshop generates a significant amount of heat, there may be concerns about the cooling capacity. Calculating the heat load might be necessary. Water-cooled chillers are suitable for large areas, offer high energy efficiency, and have low operating costs, but they require cooling towers, which may take up space and be complex to maintain. Air-cooled modules do not need cooling towers, are easy to install, but may have lower energy efficiency ratios, making them suitable for regions with water scarcity. Ground-source heat pumps are energy-efficient and environmentally friendly, but they require favorable geological conditions and a high initial investment.

TwoThe mold workshop may have air pollution issues.

For instance, oil mist and dust are concerns, thus the air conditioning system must be paired with filtering and exhaust systems to maintain air quality. A combination of methods may be necessary, such as central air conditioning with independent exhaust, or electrostatic dust removal, activated carbon filtration, etc.

Customers may be concerned about initial investment costs, operational expenses, ease of maintenance, system reliability, and whether the system can meet the requirements for workshop temperature, humidity, and air quality, as well as future scalability. It is necessary to consider these factors comprehensively, propose several solutions, analyze their pros and cons, and recommend the most suitable option.

FourCentral Air Conditioning Solution Combination Recommendation

For example, water-cooled chillers+ Modular air handling units, paired with exhaust air filtration systems, feature zonal control. Alternatively, a combination of air-cooled module units and a fresh air system may be required, especially if the workshop generates a high amount of heat, necessitating an increased cooling capacity. If the workshop is equipped with a significant number of heat-generating devices, it may only need ventilation in winter, eliminating the need for additional heating, and possibly even requiring cooling.

FiveCompute Heat Load

A 5,000-square-meter workshop with a height of 5 meters, totaling 25,000 cubic meters in volume, faces loads from equipment heat, personnel, and lighting. It may require 200-300 watts of cooling capacity per square meter, with a total cooling capacity of approximately 1,000-1,500 kW.

The recommended solution is a water-cooled chill water unit.+ Modular air handling units, paired with exhaust air filtration systems, offer zonal control and variable frequency regulation for high energy efficiency, making them suitable for large areas. Although the initial investment is high, the low operating costs make them ideal for long-term use. Additionally, they can be equipped with a fresh air system to ensure air circulation and filter dust and oil mist. Furthermore, if there are high-temperature areas in the workshop, local cooling measures may be required, such as job-site air delivery or auxiliary spray fans.
