什么是能源监测器?
通常被称为能量监测器, electric use monitoring devices count the amount of electrical energy passing through a circuit, 通常以千瓦时为单位. Most energy monitors also have power monitoring capabilities that generally make them more efficient for finding high-use devices.
能源监测仪的价格和复杂程度各不相同. Watt meters cost approximately $20 to $30, 还有整个小区的监视器 cost approximately $300. 金谷电力协会(GVEA)的仪表数据, 可以通过MyGVEA访问, can be an effective and inexpensive solution to monitor use and cost.
为什么使用能源监控器而不是其他解决方案?
There are generally only two ways to chase down high use, by manually checking circuits with a current meter or using an energy monitoring device. Manually checking circuits with a current meter works well for constant loads with a high-energy draw. 能源 monitors excel when you want to check how much electricity each device or group of devices use over time.
Electricians generally have a difficult time reliably tracking down sources of high use. This method is difficult due to the limited amount of information that can be gathered during a brief visit. 例如, let’s say most of a member’s use comes from a truck that is plugged in, 图1,每天200瓦，持续一个月. An electrician may not have the time available to track the wiring that would lead him or her directly to the truck. 另外, the member’s dishwasher may be running during the electrician’s visit, causing the hot water heater to use significantly more electricity than the truck. The electrician will see the hot water heater running and may think it’s the largest cause of high use over the month simply because it was using the most power at the time of his or her visit.
能源 monitors provide an advantage when it comes to discerning the use of inconsistent loads such as 电脑, 冰箱, 锅炉, 还有热水器. Because energy monitors look at use over an extended period of time, they can be used to measure the cost of devices much more accurately than other methods.
简单地说, using an energy monitoring device is the most efficient and accurate way to monitor your home's energy use.
不同能源监测设备之间的差异
There are 3 types of energy monitoring devices that are recommended for monitoring your home’s energy efficiency: GVEA meters monitored through MyGVEA, 插件监控, 还有整个小区的监视器.
GVEA’s AMI meters monitor energy use and provide interval data to members through the MyGVEA mobile or desktop app. GVEA interval meter data can be used to identify the use of specific devices to some extent but requires a lot more work and know-how compared to other devices. GVEA’s meters are a type of energy monitoring device and utility meter. This data can be used like that of an energy monitoring device but has some limitations.
Plug-in meters are the simplest energy monitoring devices. These devices are capable of measuring energy use for plugged-in devices like microwaves, 冰箱, 电视, 电脑, 等. 插入式仪表只能测量带有120V插头的设备. 他们无法测量更高用途的电器, 比如炉子, 烤箱, 热水器, 洗碗机, 衣服烘干机, 墙照明, 循环泵, 井泵, 等. 尽管有其局限性, plug-in meters are easy to use and more affordable than most other energy monitors.
The most complex energy monitors are residence-wide monitors, generally installed inside the main breaker panel of a home. These units require an electrician to install and a wireless connection. 取决于模型, residencewide monitors may measure the entire home or have multiple sensors to measure individual circuit breakers and areas of the house. 监控, 比如Sense, measure the total house load and use analytical software to identify the use of individual devices.
哪种能量监测设备最适合你?
Choosing the most suitable option depends on your specific circumstances. If you prefer a hands-off approach and are focused on long-term monitoring without investing much time into diagnosing your home’s use, Sense能量监测器是一个很好的选择. The Sense is among the more expensive residence-wide monitors, 花费大约300美元, it is able to identify individual devices by interpreting use patterns. 安装相对简单, you’ll generally get better use of data than other energy monitors. 由于他们如何识别负载, Sense energy monitors will work with homes where electrical circuits aren’t clearly or correctly labeled.
通过使用插入式瓦特计, you can find out how much energy and power all the plug-in devices in the house use. To identify all the uses in your house, you can use meter data in conjunction with a plug-in monitor. By turning off or on hardwired and 240V devices and checking meter interval data, you can determine the power use of devices that the watt meter isn’t capable of monitoring. 这种方法是最经济实惠的, but it requires more time than using the more advanced residence-wide energy monitors.
重点是什么??
能源 monitoring devices are best used to measure the energy use of individual devices within the home to promote long-term energy efficiency. 能源 monitors come in different forms and each one has advantages and disadvantages. No single energy monitor is perfect for every circumstance. 能源 monitors are a tool to gather information to make educated decisions on how to improve your home’s electrical efficiency in the long run.
