新型温室温度控制系统的夏季降温效果试验研究
Experimental Study on Summer Cooling Effect of New Greenhouse Temperature Control System
摘要
Abstract
This study proposes a novel greenhouse temperature control system based on a buried pipe-heat source tower.Water is used as the working medium.The system transfers heat from the greenhouse to the soil through a buried pipe heat exchanger to achieve cooling,and adjusts the water flow and the wind speed of the outlet of the heat source tower.The effects of pipe layout,pipe spacing,and burial depth on the system’s cooling performance were analyzed.The results show that the parallel arrangement of buried pipes is superior to the series arrangement,and the pipe spacing should be greater than 0.2 m.Increasing the depth of the buried pipes significantly enhances the greenhouse cooling effect,with a nighttime cooling of 2.04℃and a day-time cooling of 8.04℃at a depth of 1.5 m.The system performs optimally under conditions of an air velocity of 2.5 m/s and a water flow rate of 1.2 m2/h,achieves a cooling capacity of 7.59 kW·h,and maintains an EER of 10.3.关键词
