保持适当的室内温度对于舒适的工作条件、提高温室中种植的农产品的生产率以及节约能源是很重要的。因此，有必要测量温度分布以实现高效的空调系统。然而，我们不得不使用许多常规仪器来测量温度分布。我们提出了一种测量系统的垂直温度分布使用一对扬声器（SP）和麦克风（MIC），和声反射器。该系统由SP、MIC和多个声反射器组成，可以根据两个反射器所包围区域的平均温度来确定温度分布。在实验中，使用5个声探头在大型设施中每隔20 s测量垂直温度分布，持续24 h。实验结果表明，该系统可用于由两个反射器所围成的每个区域的平均温度来测量垂直方向的温度分布。该系统可用于测量温度分布随时间的变化。我们建立了一个简单的系统来测量垂直温度分布。(C)2009日本应用物理学会
It is important to maintain an adequate indoor temperature for comfortable working conditions, improvement of the rate of production of farm goods grown in greenhouses, and for saving energy. Thus, it is necessary to measure the temperature distribution to realize efficient air-conditioning systems. However, we have to use many conventional instruments to measure the temperature distribution. We proposed a measurement system for vertical temperature distribution using a single pair of loudspeaker (SP) and microphone (MIC), and acoustic reflectors. This system consists of SP, MIC, and multiple acoustic reflectors, and it can be used to determine the temperature distribution from the mean temperature of the area bounded by two reflectors. In experiments, the vertical temperature distribution was measured using five sound probes in a large facility every 20 s for 24 h. From the results of this experiment, it was verified that this system can be used to measure the vertical temperature distribution from the mean temperature of each area bounded by two reflectors. This system could be used to measure the change in the temperature distribution overtime. We constructed a simple system to measure the vertical temperature distribution.
