Floor height As the number of 10-meter factory buildings grows, the design of their air conditioning systems has become a crucial element in ensuring a comfortable and efficient production environment. Central air conditioning systems are a popular choice among factories due to their strong cooling and heating effects, as well as their ability to effectively control indoor air quality.
N/A A 10-meter factory building is equipped with a central air conditioning system. The following suggestions can be referred to for selection:
One: Determine the type of central air conditioning system for the factory building
1. Screw Chiller Units: These units offer high cooling capacity per machine, suitable for factories of up to 10,000 square meters. They boast high energy efficiency, can be equipped with variable frequency technology for dynamic load regulation, and ensure precise temperature control. Ideal for consistent cooling throughout the year and in areas with high heat generation, though they require a relatively high initial investment and professional maintenance.
2. Air-cooled Module Unit + Fan Coil System: The air-cooled module unit serves as the outdoor main unit, installed in a suitable outdoor location, with fan coil indoor units distributed across various areas of the factory. This system has a relatively low initial investment cost, the fan coil indoor units are compact in size, occupy minimal space, are easy to install, and the outdoor main unit is also easy to maintain.
3. Multi-split (VRV) System: Comprising one or more outdoor units and multiple indoor units, it allows for the selection of different indoor unit types based on factory layout and functional zones, such as wall-mounted units for office areas and ducted units for production workshops. It boasts high energy efficiency, automatically adjusts the compressor operation frequency based on indoor unit load for energy-saving operation, offers flexible installation, and is easy to control.
Secondly, the cooling capacity of the central air conditioning in the middle of the calculation factory building.
Please provide the Chinese content to be translated. The air conditioner is suitable for spaces of 10-16 square meters, so a 3,000 square meter workshop would require approximately 300 units. It can also be accurately calculated based on heat load, taking into account factors such as heat transfer through protective structures, equipment heat dissipation, and personnel load, to determine the total cooling load.
Choose an appropriate main machine for the factory.
1. When considering energy efficiency, opt for high-efficiency units such as those from brands like Gree, Midea, Trane, Daikin, etc. These units offer superior energy efficiency, low noise levels, and high reliability, helping to reduce energy consumption and long-term operating costs.
2. Matched with Cooling Demand: Based on the calculated cooling load, select a main unit with the appropriate cooling capacity to avoid scenarios of either excessive or insufficient cooling. Ensure the air conditioning system operates efficiently and achieves optimal cooling or heating effects.
Section 4: Terminal Equipment and Air Distribution Method Selection
1. Jet Air Conditioning Units or Ductwork + Jet Air Outlets: For tall and spacious factory buildings, this ventilation method ensures even distribution of cold and hot air to all corners of the factory, achieving excellent ventilation and improving indoor air quality.
2. Swirl Duct + Ducting: Utilizing jet air supply technology with a reach of 15-20 meters, paired with guide vane blades, it ensures a vertical temperature difference of ≤3°C, guaranteeing comfort in the working area.
3. Industrial Ceiling Fans +微风 Systems: Additional low-speed ceiling fans with a diameter of 3-7 meters are installed in the work area, enhancing human comfort through air flow disturbance and effectively reducing the perceived temperature by 2-3°C.
Section 5: Reasonably Designed Pipeline Systems
1. Duct Design: The layout and dimensions of the ducts should be designed based on the factory's layout and the air supply requirements of the HVAC system, aiming to minimize resistance losses in the ducts to ensure smooth air flow. At the same time, attention should be given to the insulation treatment of the ducts to reduce the loss of cool or heat.
2. Pipe Design: For water-cooled systems, the pipe diameter and flow rate should be reasonably selected. For loops less than 300 meters, opt for a friction factor of 0.04 to 0.05; for loops between 300 and 400 meters, choose a friction factor of 0.03 to 0.04; for loops over 400 meters, select a friction factor of 0.02 to 0.03. Generally, a parallel loop system is used; if the building height exceeds 10 floors, it is advisable to use a vertical loop system. For main trunk lines to loops over 100 meters, a horizontal loop system is recommended.
