    • A combiner that calculates energy produced by each panel feed during the daytime, and calculates a resistance value needed to calculate the energy by injecting a known current into each panel feed at nighttime and measuring the resulting voltage across a resistive element in each panel feed. A voltage tap across the protection device in each panel feed allows logic and control circuitry to measure the voltage across each protection device. At nighttime, a known current is injected into each panel feed and the voltage across each protection device is measured. Plugging the current and voltage into Ohm's Law, a resistance of each protection device is calculated, then that resistance value is used during the daytime to calculate energy produced by each string in real time and to monitor each string's performance. When an individual string's performance wanes, an alarm is indicated to help the operator troubleshoot which individual panel(s) within the string is responsible for that string's underperformance.
    • 组合器,其计算白天由每个面板进给产生的能量,并且通过在夜间将每个面板进给器中注入已知电流并测量每个面板进给中的电阻元件上产生的电压来计算计算能量所需的电阻值。 每个面板进给中的保护装置上的电压抽头允许逻辑和控制电路测量每个保护装置的电压。 在夜间,将已知电流注入每个面板进给器中,并测量每个保护装置上的电压。 将电流和电压插入欧姆定律,计算每个保护装置的电阻,然后在白天使用该电阻值实时计算每个串产生的能量并监测每个串的性能。 当单个字符串的性能下降时,会显示一个警报,以帮助操作员排除字符串中哪个单独的面板对该字符串的性能不佳负责。

    • A valve apparatus can be used to select between a cold or a hot coolant for heat exchange, this selection depending on whether an attached heat exchanger is to operate as a cooler or a heater. The apparatus includes a valve housing with first and second chambers formed therein, first inlet and outlet ports for flow of a primary liquid into and out of the first chamber and further ports for flow of coolant at different temperatures through the second chamber. A linear actuator in the housing has a body containing wax and a plastic piston that is movable to an extended position by expansion of the wax. The actuator body is located in the first chamber so the temperature of the wax is dependent on the liquid's temperature in the first chamber. An end portion of the actuator adjacent to the second chamber is made of plastic. A valve mechanism for controlling coolant flow is operably connected to the piston and located in the second chamber. This mechanism includes a spool movable by the actuator.
    • 阀装置可用于在冷或热冷却剂之间进行热交换,这取决于连接的热交换器是作为冷却器还是加热器来运行。 该装置包括具有形成在其中的第一和第二室的阀壳体,用于使初级液体流入和流出第一室的第一入口和出口以及用于在不同温度通过第二室流动的冷却剂的另外的端口。 壳体中的线性致动器具有包含蜡的主体和通过蜡的膨胀可移动到延伸位置的塑料活塞。 致动器主体位于第一室中,因此蜡的温度取决于第一室中液体的温度。 致动器的靠近第二室的端部由塑料制成。 用于控制冷却剂流动的阀机构可操作地连接到活塞并且位于第二室中。 该机构包括可由致动器移动的线轴。

    • A thermal bypass valve for a heat exchanger circuit includes a valve housing forming a valve chamber including a bypass passage and ports for the flow of heat exchange fluid into and out of the valve chamber as well as a bypass port defined by a valve seat. Two axially aligned thermally sensitive actuators are mounted in the chamber, each with an actuator body and its own movable piston extendible from one end of the body. One of these pistons operably engages the actuatory body associated with the other piston. Each actuator body is normally movable in the chamber in response to extension of its piston. One of the actuators extends its piston at a higher temperature than the temperature required for the other actuator to extend its piston. A bypass valve member is mounted on one of the actuators and can be moved by either actuator from an open position to a closed position.
    • 一种用于热交换器回路的热旁通阀包括形成阀室的阀壳体,该阀室包括旁通通道和用于使热交换流体流入和流出阀室的端口以及由阀座限定的旁通端口。 两个轴向对准的热敏感致动器安装在腔室中,每个具有致动器本体,并且其本身的可移动活塞可从主体的一端延伸。 这些活塞中的一个可操作地接合与另一活塞相关联的致动体。 响应于其活塞的延伸,每个致动器主体通常在腔室中可移动。 其中一个致动器将其活塞的温度比其他致动器延伸其活塞所需的温度更高。 旁通阀构件安装在一个致动器上,并且可以由任一致动器从打开位置移动到关闭位置。
