Discussion on installation details of air conditioning engineering for operating room purification, workshop purification and laboratory purification
Release time:2020-01-06 source:
Air conditioning purification project is a product of building decoration, purification air conditioning, pure water and gas, electrical control and other professional technologies, which is widely used in operating room purification, workshop purification, laboratory purification and other fields. At the same time, the air conditioning purification project is also a big energy consumer. In the design and construction, attention should be paid to energy-saving measures, division of systems and areas, calculation of air supply volume, determination of temperature and relative humidity, determination of cleanliness level and air change frequency, fresh air ratio, air duct insulation, the influence of bite form in air duct production on air leakage rate, the influence of connection angle of main pipe and branch pipe on air flow resistance, flange connection Air leakage, air conditioning box, fan, water chiller and other equipment selection are all related to energy consumption, so these details must be taken into account.
1. Set automatic control device to ensure full adjustment
At present, some air conditioning and purification engineering manufacturers use manual way to control the air volume and air pressure. However, because the regulating valves controlling the air volume and air pressure are in the technical compartment, and the ceiling is also the soft ceiling of color steel plate, which is basically adjusted during the installation and commissioning. Since then, most of them have not been adjusted, and in fact, they cannot be adjusted. In order to ensure the normal production and work of the clean room project, a set of relatively complete automatic control device shall be set to realize the following functions: clean room air cleanliness, temperature and humidity, pressure difference monitoring, air valve regulation; temperature, pressure and flow detection of high-purity gas, pure water and circulating cooling water; gas purity, pure water quality monitoring, etc.
2. Multi machine chiller should be selected for the purification project of dust-free workshop with large refrigerating capacity
If the cooling capacity of the chiller is required to be large, it is not suitable to select a single machine, it is better to use multiple mechanisms, and the motor is better to use frequency conversion speed regulation to reduce the starting power. Multiple machines can be used flexibly, so as not to waste energy.
3. Select air conditioning box according to climate conditions
As for the selection of air conditioning box for operating room purification, workshop purification and laboratory purification, the climate environment should be considered. For example, in the north area with low temperature and large dust content in winter, the new air preheating section shall be added to the general air conditioning unit, and the water spraying air treatment mode shall be adopted, so as to wash the air dust and make the heat exchange reach the required temperature and humidity. In the south of China, where the climate is humid and the dust concentration in the air is low, there is no need to preheat the fresh air in winter. The primary filter is used to filter the air and adjust the temperature and humidity. The surface cooling surface can adjust the temperature and humidity. It can also strengthen the temperature and humidity reduction process, and then through the intermediate filter and terminal high-efficiency or sub high-efficiency filter.
4. Air conditioning room should be designed at the side of clean room
The location of the air conditioning room of the purification project should be designed at the side of the clean room, which can not only save energy, but also be conducive to the arrangement of the air duct in the ventilation and air exchange project, and make the air distribution more reasonable, at the same time, it can save the cost of the central air conditioning project.
