Problems solved by technology

[0008] From the perspective of facility composition cost analysis, if the cooling pipe is configured separately, the steel consumption is relatively large, and the cost is also high. The adjustment and transformation of water supply and return pipelines are formed, and the additional cost is relatively low

Abstract

A pipe cooling system using the circulating underground water for joint greenhouse close to each other tightly is composed of the pipeline system, structural tubular rods, overhead ditches, fan and water well.

Description

Technical field [0001] The invention relates to a facility system for cooling greenhouses in summer by using groundwater, in particular to an underground water pipeline circulation cooling system for multi-span greenhouses. [0002] Especially in southern China, where the shallow groundwater content is relatively rich, and the climate conditions are often high temperature and high humidity, and the application of conventional water evaporation cooling has limitations, the summer greenhouse cooling solution and equipment system for groundwater pipeline cooling are proposed. . Background technique [0003] In recent years, multi-span greenhouses, as the main body of modern horticultural facilities, have developed rapidly in various places, and have been used more and more in the cultivation of vegetables, flowers, seedlings, etc. In order to reduce seasonal restrictions and achieve year-round production, cooling must be considered in summer Generally speaking, when the outsid...
