当印度政府于二零二零年三月二十五日宣布首次封锁以控制不断增加的COVID-19病例时，人们被迫留在家中工作。本研究旨在量化居家订单对住宅空调（AC）能源和家庭用电量（不包括AC能源）的影响。这是使用来自印度海得拉巴五栋建筑中380户家庭的监测数据完成的。我们于2019年4月及2020年4月每隔30分钟收集每户住宅的交流电能源及家庭用电量数据。对这些数据进行描述性和推断性统计分析。为抵销2019年及2020年4月的气温差异，仅选取2019年平均气温与2020年平均气温相同的平日。该研究确定，根据2020年的温度，每个家庭每天使用AC的平均小时数增加了4.90-7.45%。相应地，二零二零年整体空调消耗量增加3. 60 - 4. 5%，但日间（上午8：00至晚上8：00）空调能耗增加22-26%，而夜间（晚上8：00至上午8：00）空调能耗减少5-7%。该研究显示，2020年全年家庭用电量增加约15%。家庭用电量白天增加22- 27.50%，夜间增加1.90- 6.6%。据观察，早上的家庭用电高峰需求由二零一九年的上午七时转移至二零二零年的上午九时。相反，晚高峰需求从2019年的晚上9点转移到2020年的晚上7点。下午在封锁期间观察到另一个高峰。
When the Indian government declared the first lockdown on 25 March 2020 to control the increasing number of COVID-19 cases, people were forced to stay and work from home. The aim of this study is to quantify the impact of stay-at-home orders on residential Air Conditioning (AC) energy and household electricity consumption (excluding AC energy). This was done using monitored data from 380 homes in a group of five buildings in Hyderabad, India. We gathered AC energy and household electricity consumption data at a 30-min interval for each home individually in April 2019 and April 2020. Descriptive and inferential statistical analysis was done on this data. To offset the difference in temperatures for the month of April in 2019 and 2020, only those weekdays were selected where the average temperature in 2019 was same as the average temperature in 2020. The study establishes that the average number of hours the AC was used per day in each home increased in the range 4.90–7.45% depending on the temperature for the year 2020. Correspondingly, the overall AC consumption increased in the range 3.60–4.5%, however the daytime (8:00 AM to 8:00 PM) AC energy consumption increased in the range 22–26% and nighttime (8:00 PM to 8:00 AM) AC energy consumption decreased by 5–7% in the year 2020. The study showed a rise in household electricity consumption of about 15% for the entire day in the year 2020. The household electricity consumption increased during daytime by 22- 27.50% and 1.90- 6.6% during the nighttime. It was observed that the morning household electricity peak demand shifted from 7:00 AM in 2019 to 9:00 AM in 2020. Conversely, the evening peak demand shifted from 9:00 PM in 2019 to 7:00 PM in 2020. An additional peak was observed during afternoon hours in the lockdown.
