Problems solved by technology

Because the air is relatively dry in northern my country, the cooling effect of practical application is more obvious, while in most provinces in southern my country, there is generally high temperature and high humidity in summer, and the average humidity in many areas reaches about 80%. On the one hand, during the cooling process, the greenhouse The internal humidity will increase, and the resulting high humidity is not good for crop growth; on the other hand, its cooling effect is limited by high humidity, and in extremely hot climates, the cooling rate is difficult to meet the crop production requirements

Embodiment Construction

[0018] Such as figure 1 , figure 2 As shown, the outside of the greenhouse under the outer sunshade curtain 1 is covered with a cooling film 2, and several groundwater circulation pipes 3 are arranged inside the greenhouse, and the two ends of each groundwater circulation pipe 3 are respectively connected with the main water supply pipe 7 and the main return water pipe 8. The rubber tube 9 is connected, and the movable underground water circulation pipeline 3 is suspended on the upper frame of the greenhouse with the hanging chain 6 .

[0019] Such as image 3 , Figure 4 As shown, on the basis of the combined cooling device of the multi-span greenhouse of the above-mentioned cooling film and underground water circulation pipeline, a wet curtain fan system composed of a wet curtain 4 and a fan 5 is also arranged inside the greenhouse, and the wet curtain 4 is arranged in one of the greenhouses. The lower part of the end face or side, the fan 5 is arranged on the other end ...

Abstract

A combined cooling system using cooling film and the pipeline of circulation underground water for joint green houses close to each other tightly is composed of the cooling film spread under the sun shielding net, circulating pipeline of underground water, water supplying trunk, water returning trunk, wet curtain and blower.

Description

Technical field [0001] The invention relates to a multi-span greenhouse combined cooling system adopting a cooling film and an underground water circulation pipeline. [0002] Especially in the southern part of my country, the climate is often high temperature and high humidity, and there are often extremely hot weather conditions. In the case of limitations in the use of conventional combined cooling methods, the summer greenhouse is proposed by taking advantage of the favorable conditions such as rich shallow groundwater content. Effective solutions and combined configurations for cooling. 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 And other measures,...
