For example, in the environment of southern high-temperature and high-humidity areas, 8-9 months per year, the external environment temperature is above 35 ℃ for a long time, and the heat and humidity load of a production workshop is the heaviest. Under the original working condition, the temperature of the materials entering the cabinet is high, the weight of the materials entering the cabinet in each batch is 6-8 tons, the materials become a huge heat source body, the circulating air frequency of the leaf storage room reaches 11 times/hour, the total air supply quantity of the air conditioning unit 10 exceeds 120 ten thousand cubic meters/hour, and the energy consumption such as fresh air handling capacity, steam consumption, chilled water consumption, power consumption of a driving fan and the like is very high.
Two newly-added air conditioning units 10 with the air volume of 15000 cubic meters per hour and the total air volume of 30000 cubic meters per hour are improved, and the scheme is adopted to convey air conditioning air with the temperature and humidity adjusted to the leaf storage cabinet body 1 for adjusting and balancing the temperature and the water content of materials. When no material exists in the leaf storage cabinet body 1 for production turnover, the control valve 7 closes air supply to the first air supply pipe 2 and the second air supply pipe 5, and the air conditioning unit 10 is in a heat engine or low-frequency working state. Monthly operating conditions were recorded as follows:
A. the leaf storage cabinet is used for the production process, the turnover inlet and outlet materials are 2-8 cabinets, the total air supply quantity range of the air conditioning unit 10 is 3000-;
B. the average relative humidity of the air supplied by the air conditioning unit 10 is 78.5%, the average temperature is 32.3 ℃, the temperature of the discharged materials is 33-37 ℃, and the water content is 18.5 +/-1.0%, so that the process requirements are met;
C. two air conditioning units with the air volume of 15000 cubic meters per hour are newly added, wherein one air conditioning unit is full, the other air conditioning unit has the production load less than 20 percent, and the original 120000 cubic meters per hour air conditioning unit is stopped; in the aspect of monthly energy consumption statistics, the fresh air treatment capacity is reduced by 2000-3000 cubic meters/hour from the original 12000-20000 cubic meters/hour, and is reduced by more than 80 percent on the same scale; the steam consumption is reduced by 60 percent at the same ratio, the chilled water consumption is reduced by more than 40 percent at the same ratio, the electric energy consumption of the driving fan is reduced by 53 percent at the same ratio, and the comprehensive energy consumption is reduced by more than 50 percent at the same ratio.
For example, aiming at the special 'backsouth China' climate of the south winter and spring, the relative humidity of the external environment is more than 90%, the temperature is 15-20 ℃, and water drops are condensed on the wall and the ground of the external environment. Under the working condition, the maximum load of the air conditioner of the leaf storage room in the production workshop shows that the air is dehumidified, the circulating air frequency of the leaf storage room reaches 8-10 times/hour, the total air output of the air conditioning unit 10 is 100 plus materials, and the energy consumption is high, wherein the total air output of the air conditioning unit is 110 ten thousand cubic meters/hour. Meanwhile, the temperature and humidity in each area in the leaf storage room are seriously layered and the overall working condition effect is poor due to the restriction of factors such as air supply and air return process layout of the leaf storage room, intensive process equipment, limited air supply distance of air supply speed and air supply distance, the relative humidity fluctuation range of the leaf storage cabinet, the head cabinet, the tail cabinet and the middle cabinet of the same leaf storage cabinet often exceeds +/-10 percent, and the safety risk and the product quality risk are high.
After the technical scheme is adopted, the operation mode is as follows:
A. aiming at the material process control requirement in the production process, the air conditioning unit 10 conveys air conditioning air with the regulated temperature and humidity to the leaf storage cabinet body 1 through a connecting pipe 3, a control valve 7, a first blast pipe 2 and a second blast pipe 5, is used for regulating and balancing the temperature and the moisture content of the material, and performs air supply operation according to 2000 cubic meters/cabinet/hour;
B. the single cabinet operation mode coping with extreme working conditions is as follows, and the actual conditions are scheduled according to the production of No. 1-12 cabinets, such as: 1-3 groups of the production turnover materials are selected from No. 1-6 cabinets without materials, and 2500 cubic meters per cabinet per hour air supply operation is carried out to balance the distribution of the temperature and the humidity of the whole environment of the leaf storage room;
C. the air conditioning unit operating mode of coping with extreme working conditions is as follows, suitably reduces the return air volume of air conditioning unit 10, increases the new trend throughput, and its main purpose is to increase the positive pressure of leaf storehouse relative to external environment, reduces the interference of outside high humid air to leaf storehouse environment.
After the implementation of the embodiment, when the extreme working condition of 'returning to south' is responded, the temperature and the humidity of the whole environment of the leaf storage room are integrally controlled in a standard range, the phenomenon of condensation and water dripping due to temperature difference and humidity difference is not found, the safety of internal electrical equipment is improved, and the potential hazards of yellow spots and mildew quality accidents of products are reduced.
