温度调节中的能量消耗,对于大型建筑(像礼堂,剧院,会议厅及大型冷库等)来说,是一个重要的经济指标。在制冷系统中消耗能量的主要部件是压缩机和风扇电机。总假定在冷风进入调节空间的入口处设置一个温度传感器,它给出温度讯号,通过调节器控制压缩机的工作,使得这一点的温度达到给定值。风扇则促使空气流动,改善空间温度分布的均匀性,以期室内各点温度均在预先给定的范围内。 干扰影响室内温度的主要因素是环境温度和人员或产品的流动。本文主要讨论在稳态情形下,如何用最小的能量来抵御环境温度的干扰,同时保证室内温度在给定的范围内。至于动态控制问题,将另研究。
Energy consumption in temperature regulation is an important economic indicator for large buildings such as auditoriums, theaters, conference halls and large cold storage. The main components that consume energy in refrigeration systems are compressor and fan motors. It is generally assumed that a temperature sensor is provided at the entrance of the cold air into the conditioning space, which gives a temperature signal and controls the operation of the compressor through the regulator such that the temperature at this point reaches a given value. The fan will promote the air flow and improve the uniformity of temperature distribution in the room, so that the indoor temperature of each point are within a predetermined range. The main factors that interfere with the indoor temperature are the ambient temperature and the flow of people or products. This article focuses on how to minimize interference with ambient temperature in a steady-state situation while ensuring that the room temperature is within a given range. As for the issue of dynamic control, another study will be conducted.
