| In order to ensure product quality and the stability of equipment of cigarette, cigaretteenterprises equipped with central air-conditioning system, regulation of air temperature andhumidity, to meet the requirements of process index. However, the central air conditioningsystem energy consumption accounts for over20%of the cigarette production powerconsumption. Therefore，in order to tobacco enterprise as an example, presents theair-conditioning and refrigeration system on-line operation mode，to develop energy-savingstrategy, study its engineering application effect.Central air conditioning system is mainly composed of refrigeration, cooling tower，chilled water and cooling water supply system and the wind cabinet. The cigarette companyrefrigeration machine for screw chiller，the main energy consumption energy. Research goal is,through adjusting the parameters in the summer of chillers in transition season, effective useof cold energy in external environment, ensure the operation area of temperature and humidityto process requirements and to ensure the operation area population demand under thepremise, the maximum to lower the consumption of electric energy.I think over the past few years the company where the transition season in Shaoguan areathe outdoor temperature and humidity and water temperature data statistics and outdoorsummer cooling water temperature, and consider the simple change of air return devicemethod proceed with，through access to information, calculation and repeated test, in summerand winter in the two season to ifnd a for my jurisdiction air-conditioning operation feasiblesolution, formation control, achieve better energy-saving effect.The main content of this article have:1Parameters of the equipment after adjustment for temperature and humidity ofenvironment, host running stability and system energy consumption;2cooling water, chilled water after being connected in series fan system load, the fancoil and the effect of system energy consumption;3determining the cooling water instead of frozen water and outdoor cold air coolingwhen the outdoor temperature and humidity limit;Through access to relevant information, according to the actual scientiifc calculation andevaluation, use time of two years of equipment parameters improvement and equipmentannex process validation, a series of experiment content can obtain certain energy-savingeffect，to meet the cigarette environment temperature and humidity requirements of thepremise, the appropriate increase of chilled water temperature, can make chiller refrigerationcoeiffcient increased by10%，the transition season through inhalation of outdoor air coolingcapacity, reduce the water chiller load, thereby reducing water chillers and auxiliary pumpsamount, achieve the purpose of saving energy, the main building of two floors improvedconversion system, low power consumption for the50%or so. And in the transition season byusing cooling instead of frozen water, make chillers and chilled water pump stopped, just usethe cooling water pump cooling water in the circulating system of the enterprise, theexpanded tobacco workshop area improved, which makes the whole central air conditioningsystem power consumption reduced by69%. |
