Regarding the air conditioning system of clean room, I believe everyone knows that the heart is very important and can also ensure the stability of clean workshop environment. In order to achieve better production and maintain the stability of products, the use of air conditioning system is very important. So how to use it to ensure the energy efficiency of air conditioning purification system? 1, reduce the fresh air load of air conditioning. In order to better realize the energy-saving measures of clean workshop and reduce the exhaust air volume, the internal friction will naturally be less, so that the whole workshop design will be more closed. The design of exhaust hood can not only ensure the exhaust effect, but also minimize the exhaust air volume, which naturally makes the energy consumption of air conditioning system less. 2. For the use of sealed air conditioning system and air leakage air conditioning system, these problems should be fully considered. It is best to improve the actual efficiency of the air conditioner and reduce the air leakage at work, which will naturally make the performance of the air conditioner more stable. Improve the efficiency of air conditioning fresh air treatment equipment. For the use of air conditioning system in clean workshop, it can not only ensure the fresh air load, but also increase the load of process equipment and technology, which naturally improves the actual energy efficiency in the use process. Improve the use efficiency, ensure the overall air conditioning performance of the clean workshop, naturally increase the load and give full play to energy-saving measures. This can reduce the energy consumption of air conditioning system to the greatest extent, and better realize the environmental protection measures of energy saving and emission reduction, so that the whole internal working environment will not be affected.
How to save energy in cleaning engineering system of dust-free workshop
In order to reduce the operating cost, Anhui Renhe Environmental Protection Technology Co., Ltd. and many other companies have designed the following operating modes of constant temperature and humidity air conditioners: (1) The temperature and pressure of cooling water change with the seasons; In summer, due to the high atmospheric temperature and humidity, the air needs to be cooled and dehumidified before being sent to the production site, and the outdoor air humidity is usually higher than 85%). Then we will control the freezing temperature at 6 ~ 7℃ and the pressure at 5-5.5 kg/cm2. In winter, if the chilled water is at or above this temperature and pressure, it is difficult to control the opening of the chilled water valve of the air conditioner. Finally, all the valves of chilled water, heating and humidification were opened. As a result, in order to save energy, we controlled the temperature of chilled water in the range of 8- 1 1℃ and the pressure in the range of 2.7-3.5 kgf/cm2. Through this simple adjustment, only two valves (chilled water, heated or chilled water and humidification) need to be opened in winter, and the average daily steam cooling capacity of 60 air conditioners in winter is 400 USRT 30 t. (2) The lower limit of pressure difference control in each process is 0.5 mm water column (5 pa), and only one dual-motor air conditioner should be opened as far as possible. As mentioned in the previous section, our cleaning ranks first, and the cleaning result is lower than 1000. After careful calculation of air supply volume, air exchange times, temperature and humidity changes, the air volume decreased, so it was decided to change some double fans to single fans to operate air conditioners, and increase the fresh air volume appropriately, and the cleanliness also decreased slightly. Humidity parameters, such as temperature, (3) According to the characteristics of Shenzhen, the reference standard of temperature and humidity of constant temperature and humidity air conditioner should be raised appropriately (that is, the enthalpy should be increased) to save cold and heat. For example, the initial design conditions of our electron gun project and film project are: 22℃, 55%; 22.5℃,65%。 After gradual improvement, the temperature and humidity were increased to 24℃, 55% and 24.5℃, 65% respectively. In summer, in order to reduce the cooling and dehumidification load of cooling water, we will appropriately increase the set value of dehumidification air conditioner and the control range of heating cooling water in summer, such as 24℃, 55% to 24.3℃, and reduce the humidity set value when the air conditioner is turned on for isothermal humidification with chilled water, such as 24.5℃ (65%) to 24.5℃ (62%). The fresh air volume and exhaust air volume are the smallest in summer; Maximum fresh air volume and exhaust air volume allowed for air conditioning in winter. Comfortable air conditioner is equipped with temperature controller, which really controls the ambient temperature at 26 ~ 28℃ to achieve the maximum energy saving purpose.
