摘　　要：南疆温室等农业设施的需求较大,但现有的电加热温室控制方式能耗较大,影响温室的节能控制,温度控制也有待进一步优化。水源热泵技术可将水处理与温室温度控制系统结合起来,达到节能与温度优化控制的效果。针对南疆农业设施的资源利用与温度控制问题现状,利用水源热泵技术与PLC控制技术,设计出可进行自动温度调节的南疆温室内部温度智能控制系统。试验结果表明,系统设计合理,在南疆室外温度条件下,温室内部的温度控制稳定可靠,实用性较强;在温室控制优化测试中,室内温度值稳定在±2℃之间,属于温室的较优控制范围;在能耗的对比上,热泵系统节能效果明显,与电加热系统相比较,节能效果明显。According to the situation of agricultural wastewater treatment resources and temperature control in southern Xinjiang, a greenhouse heating intelligent control system with automatic temperature regulation function was designed with the sewage source heat pump technology and PLC control technology. The test results show that the design of the sewage source heat pump system is reasonable, and its temperature control is stable and reliable under the condition of Southern Xijiang outdoor temperature. In the optimization test of greenhouse control, the indoor temperature can be stably controlled in the range of ±2 ℃, which is the optimum control range of a greenhouse. The energy-saving effect of the heat pump system is more obvious, compared with that of the electric heating system.
