Abstract
A microcontroller based, thermal energy meter cum controller (TEMC) suitable for solar thermal systems has been developed. It monitors solar radiation, ambient temperature, fluid flow rate, and temperature of fluid at various locations of the system and computes the energy transfer rate. It also controls the operation of the fluid-circulating pump depending on the temperature difference across the solar collector field. The accuracy of energy measurement is ±1.5%. The instrument has been tested in a solar water heating system. Its operation became automatic with savings in electrical energy consumption of pump by 30% on cloudy days.
1 Introduction
Solar water heating systems find wide applications in industry to conserve fossil fuel like oil, coal etc. They employ motor driven pumps for circulating water with on-off controllers and calls for automatic operation. Reliability and performance of the system depend on the instrumentation and controls employed. Multi-channel temperature recorders, flow meters, thermal energy meters are the essential instruments for monitoring and eva luating the performance of these systems. A differential temperature controller (DTC) is required in a solar water heating system for an automatic and efficient operation of the system. To meet all these requirements, a microcontroller based instrument was developed. Shoji Kusui and Tetsuo Nagai [1] developed an electronic heat meter for measuring thermal energy using thermistors as temperature sensors and turbine flow meter as flow sensor.
摘 要
适用于太阳能热系统的单片机热能表控制器（TEMC）已经研制成功。它能够监测太阳辐射，空气温度，流体速度，在不同地点系统的流体温度和计算能量的传输速率。它也能根据全国太阳能极热地的温差来控制流体循环泵的操作。电能计量准确度为± 1.5％。该仪器已经过太阳能供热水系统的测试。阴天自动调到节能模式节能70％。
1 绪 论
太阳能热水系统在工业上有着广泛的应用，因为它能节约化石燃料如石油，煤炭等。使用电机驱动泵和开关控制器自动循环水源。系统的性能和可靠性依赖于仪器的精度和控制。多通道温度记录仪，流量计，热能表，负责监察和评估这些系统性能的重要手段。温差控制器（DTC）是一种能够自动高效的运作太阳能热水系统的控制器。为了满足所有这些要求，基于微控制器的仪器已经开发。Shoji Kusui和Tetsuo Nagai发明了一种电子热能表，用于测量热能。这种表使用了热敏电阻和作为流量传感器的涡轮流量计。
