Why the combination system of desiccant dehumidifier and cooling coils is better than only dehumidifier + AHU separately in pharmaceutical plant?

1. Dehumidification Efficiency

The combination of desiccant dehumidifier and cooling coils enhances both dehumidification and temperature regulation. This system is significantly more effective than using a desiccant dehumidifier + AHU separately. The benefits are as follows:

1. Higher Dehumidification Efficiency: Desiccant dehumidifiers operate by absorbing moisture from the air using desiccants (such as silica gel). This is particularly effective in high-humidity conditions. When combined with cooling coils, water vapor in the air condenses into water droplets, the low temperature and high humidity goes through the rotor for further dehumidify, enhancing dehumidification efficiency. In contrast, an AHU and dehumidifier separately, while capable of regulating temperature and humidity, may have limited dehumidification efficiency, particularly in high humidity conditions.
2. Precise Humidity Control: Pharmaceutical production workshops require highly precise humidity control, and the combination of desiccant dehumidifiers and cooling coils system performs better in this regard. The system can effectively respond to fluctuating humidity levels, ensuring that the workshop's environment remains within the ideal range, avoiding undesirable effects from excessive or insufficient humidity.

2. Automated Control

Automation is a key component in modern production workshops. One of the advantages of combining system of desiccant dehumidifier and cooling coils is the ability to achieve more precise automated control of temperature and humidity. Advanced sensors and control systems can continuously monitor environmental conditions and automatically adjust the system based on preset parameters. This offers better control compared to traditional dehumidifier + AHU units, which may require more manual intervention for fine-tuning.

1. Real-Time Monitoring: Sensors continuously track temperature and humidity data, allowing the system to respond promptly to even minor changes in the environment. The automated control system adjusts the operation of desiccant dehumidifier and cooling coils to maintain optimal conditions.
2. Remote Control and Adjustment: Modern systems can integrate with a central control system, enabling remote management through computers or smart devices. This improves convenience and reduces human error, minimizing downtime.

3. Energy Savings

Energy efficiency is a significant concern across industries, particularly in pharmaceutical industry. Traditional dehumidification systems often rely heavily on energy to maintain performance, especially when humidity levels are high, necessitating extensive cooling systems. However, combining desiccant dehumidifiers with cooling coils enables more efficient energy use.

1. Reduced Energy Consumption: Cooling coils help lower the air temperature while simultaneously removing moisture, reducing the load of desiccant dehumidifier. Compared to AHUs alone, this combination reduces energy consumption by effectively managing both temperature and humidity.
2. Reduced System Load: The desiccant dehumidifiers handle the bulk of the moisture removal, while the cooling coils further reduce the air temperature. This combination system reduces the frequency of activation for cooling equipment, decreasing system load and extending the lifespan of equipment while minimizing energy waste.

So, pharmaceutical production workshops where requires precise control of temperature and humidity. The combination system of desiccant dehumidifier and cooling coils offers more accurate humidity control and better dehumidification efficiency compared to the traditional only dehumidifier + AHU separately. This integrated solution provides significant advantages in terms of energy efficiency, automatic control, and dehumidification performance. By adopting this system, pharmaceutical companies can ensure stable product quality while improving the intelligence and energy efficiency of the production environments, leading to higher economic and environmental benefits.
