How can pharmaceutical air conditioning systems reduce operating costs by 40%
Pharmaceutical factories need to meet GMP requirements in the production process, and the temperature, humidity and cleanliness should be controlled within a certain range.
Under general circumstances, the temperature should be controlled at 18℃~26℃, the relative humidity should be controlled at 45%~65%, the pharmaceutical factory clean area is divided into ABCD level. The C and D level of the workshop will be relatively more , it refers to the production of sterile drugs in the process of the less important degree of clean operation area.
To meet these requirements, chiller and modular AHU are required.
The clean air conditioning system of the pharmaceutical factory use a large amount of electricity, accounting for about 50% of the total electricity consumption of the factory, which causes a great economic burden on the pharmaceutical factory. How to reduce the operating cost is particularly important for each pharmaceutical enterprise.
We have been engaged in the air conditioning system design and project implementation of pharmaceutical plants for more than 20 years, and participated in the construction of more than 20 pharmaceutical plant projects. We have some practical experience on how to reduce the operating cost of purification air conditioning system of pharmaceutical plants, so as to provide some references for you to help you to reduce the operating costs by 30%-40%.
1. High efficiency and energy saving chiller adopted. Such as: flooded type screw chiller and centrifugal chiller. The refrigeration efficiency is higher than the ordinary screw type chiller about 15%.
2. To avoid the energy wasting and increase energy efficiency, the cooling capacity requirements of pharmaceutical plants varies greatly due to the change of temperature and the installation places. Especially in transition season, the cooling capacity will be required less. When selecting chillers, you need to consider choosing more unit instead of just one . The control system can be designed to have automatically selection on the number of chiller to start and the operating load ratio of each chiller. Compared with the choice of one unit, the energy saving effect is much better to install more chiller unit, and it is safer to use. Each chiller can be used as back up if it’s at partial load,so as to save energy and be more efficient.
3. The combined AHU adds a coil cooler for fresh air in the section of fresh air treatment, which first mixes fresh air to 13℃ with return air and then goes through the fin coil, humidification and heating treatment to the set air supply state point, to compare with the traditional air treatment mode can save 10% energy
4. Using enthalpy difference technology, when the outdoor temperature is lower than 15 ℃ during the transition season. Increase the fresh air volume without the cooling from chiller can reduce the chiller starting time for 3 months per year and reduce a lot of running electricity costs.
5. Adopted fully automatic control. When one of the chiller is shut down, the corresponding water pump and cooling tower will also stop running, the temperature and humidity of the workshop will be all automatically controlled, to save 3% to 10% of the operating costs.
