Energy saving design of preparation GMP workshop
The energy-saving design of pharmaceutical workshops is a very important part. Compared with the energy-saving design of ordinary buildings, the energy-saving design of pharmaceutical workshops is more difficult and involves a wide range of knowledge. It not only involves knowledge of construction, but also requires heating engineering, Knowledge of air-conditioning systems and other aspects requires professional comprehensive designers to make overall planning; for preparation GMP workshops, they often have strict requirements on air cleanliness and require complex air-conditioning and purification systems, making their energy consumption particularly prominent, so energy saving The problem is an important problem that cannot be ignored in the process design of pharmaceutical engineering.
Doors and windows are the most energy-intensive parts of the peripheral structure, and are the focus of energy-saving design in the formulation pharmaceutical cleanroom. Controlling the ratio of windows to walls and adjusting the heat transfer coefficient of the enclosure structure under the premise of ensuring permeability can achieve the purpose of reducing energy loss. ; Improve the thermal insulation performance of the window by increasing the number of glass layers and reduce the cost at the same time. Single-frame double-glass is a good choice. In addition, the area ratio of the window frame should not be too large, and materials with low thermal conductivity and environmental protection should be selected; The sealing design ensures the airtightness of doors and windows, reduces the infiltration of cold air, and reduces energy consumption. Controlling the area of u200bu200bthe clean room and controlling the air volume ratio can effectively reduce the power consumption caused by the air supply. In addition, the high-level clean room should be closer to the air conditioner to shorten the pipeline and reduce the energy loss; use a tunnel-type or tunnel-type clean room It can reduce the area of u200bu200bthe clean room, reduce the air supply, and the energy saving effect is better. Zhongjing Global Purification can provide consulting, planning, design, construction, installation, transformation and other supporting services for preparation GMP workshops and clean rooms.
According to the requirements of GMP, the ventilation frequency of the B-level clean area is usually 40-60 times/H, and the C-level clean area is 20-40 times/H. There may be a misunderstanding here. For safety, all ventilation times are Take the highest value, such as 60 times/H for Class B, which will have a great impact on the owner's initial investment and future operating costs; the number of air changes is determined by the cleanliness level of the room, the final index and the room's cooling and heating load. The same is the B-level standard. If the room equipment produces less dust, the equipment has a high degree of automation, there are few operators, and the operators have good working habits and protection, so the number of air changes does not have to reach 60 times/H, otherwise the equipment and production process The amount of dust produced is large, the staff is dense, the equipment and production process generate a lot of heat, and 60 times/H may not be enough; therefore, the key to energy saving is to calculate the number of air changes according to the actual situation of each project.
Local exhaust air does not operate all day long, and the fresh air volume can be adjusted continuously according to the change of exhaust air volume or the change of indoor positive pressure to maintain the established positive pressure; the ventilation volume of the preparation pharmaceutical cleanroom is large, so a large amount of cold and hot media needs to be consumed Energy, rational use of outdoor fresh air to save energy, reduce the use of chilled water and heat energy, can save a lot of operating costs.
