Abstract

Energy audit is considered as one of the comprehensive methods in checking the energy usage and wastage in facilities/buildings. This paper presents the results of the energy audit conducted to investigate the energy consumption pattern of tannery company from its record of fuel expenditure and electricity bills for a period of 5 years (2012 - 2016). Also, the use of energy models system, Energy Quick Energy Simulation Tool (eQUEST) to evaluate the consumption of the energy end users and performance of the company. Results shows peak electricity demand during the hot months from April to August due to high cooling or significant Air condition requirement. 2.37% of electricity consumed was contributed by the burning of AGO in the diesel power generators showing very less contribution over that of National grid 97.63%. The annual average consumption demand of electricity and diesel (kWh equivalent) of the company were 118960.72 kWh and 2881.17 kWh respectively. The energy modeling and simulation results shows that the sum total of the total monthly energy consumption by the end users is 138164 kWh representing the total average value of the annual energy use in air-conditioning (space cooling) was 27%, ventilation fan 2%, factory machineries 39%, heat rejection is 4%, pump and auxiliary is 2% and area lighting 26%. Also, the total monthly peak demand by space cooling was 22372.2 kWh, ventilation fan 1376 kWh, factory machineries 14294kWh heat rejection is 4461 kWh, pump and auxiliary is 1343 kWh and area light 11023 kWh respectively having a sum total monthly peak demand by the end users to be 44969.2 kWh. This represent energy use in air-conditioning (space cooling) was 41%, ventilation fan 3%, 26% factory machineries, heat rejection is 8%, pump and auxiliary is 2% and 20% area light of the annual peak demand. The Energy Used Index (average annual electricity use per tones of leather) was found to be 717.38kWh/tones of leather/Annum.

一家制革公司的能源审计与管理:以卡诺州为例

能源审计被认为是检查设施/建筑物的能源使用和浪费的综合方法之一。本文介绍了能源审计的结果，该审计旨在调查制革公司5年(2012年至2016年)的燃料支出和电费记录中的能源消耗模式。此外，使用能源模型系统，能源快速能源仿真工具(eQUEST)来评估最终用户的能源消耗和公司的绩效。结果显示，4月至8月的炎热月份，由于制冷或空调需求较高，电力需求达到峰值。柴油发电机组燃烧AGO占总耗电量的2.37%，远低于国家电网的97.63%。公司年平均用电需求为118960.72千瓦时，年平均用电需求为2881.17千瓦时。能源建模和仿真结果表明，最终用户每月总能耗为138164千瓦时，其中空调(空间冷却)年能耗的总平均值为27%，通风机为2%，工厂机械为39%，散热为4%，泵及辅助为2%，区域照明为26%。此外，空间制冷的月总峰值需求为22372.2 kWh，通风机为1376 kWh，工厂机械为14294kWh，排热为4461 kWh，泵及辅助为1343 kWh，区域灯为11023 kWh，最终用户的月总峰值需求为44969.2 kWh。这代表空调(空间冷却)的能源使用量为41%，通风机为3%，工厂机械为26%，散热为8%，泵和辅助为2%，区域照明为20%的年度高峰需求。能源使用指数(每吨皮革的年平均用电量)为717.38千瓦时/吨皮革/年。
