Cooling, heat storage and heat preserving system for greenhouse

Abstract

The invention provides a cooling, heat storage and heat preserving system for a greenhouse. According to the cooling, heat storage and heat preserving system, the temperature of the greenhouse can be regulated, the heat loss can be reduced, and the problems of low ground temperature and poor heat preserving effect of the existing green are solved. Ethylene foaming plates are buried at the periphery of the greenhouse and are used for isolating the heat conduction of planting soil layers in and out of the greenhouse; an inner arch frame, a light-transmitting heat preserving film and a shading heat preserving quilt are additionally arranged in the greenhouse; the shading heat preserving quilt covers the heat preserving film at night, so that the heat preserving effect is improved. The hot air at the top of the green house is transferred into a V-shaped heat-insulating heat storage body underground for heat storage by a circulating system, and meanwhile, the low temperature of the heat storage body is also circulated to the interior of the greenhouse so as to cool the greenhouse. The V-shaped heat-insulating heat storage body is formed by covering the upper surface of an ethylene foaming plate which is paved in a V-shaped groove with plastic cloth for preventing moisture and preserving heat; the contact area between the upper part of the V-shaped heat-insulating heat storage body and the planting soil layer is large, the waste heat is transferred to the planting soil layer for improving a high ground temperature; the heat stored underground is circulated above the ground for heating at night; therefore, the problems of low ground temperature and poor heat preserving effect of the greenhouse are solved.

Description

technical field [0001] The invention relates to a rural greenhouse cooling heat storage heat preservation cycle system, in particular to a method for increasing the temperature of the greenhouse. Ethylene foam boards are buried around the greenhouse to isolate the heat conduction of the soil layers inside and outside the greenhouse and reduce heat loss. It belongs to the daytime greenhouse. The underground heat storage in the greenhouse cools down on the ground, and the circulation heat preservation system uses the heat stored underground to release heat into the greenhouse at night. Background technique [0002] In the existing greenhouses, during the production in spring, autumn and winter, the temperature in the greenhouse during the day is as high as 30-40 degrees when there is no ventilation in the greenhouse. In winter, the ground temperature is less than 10 degrees. At night, straw curtains and cold-proof quilts should be added to keep warm. Some greenhouses need aux...

AI Technical Summary

Problems solved by technology

[0003] The present invention solves the problem that the temperature of the existing greenhouse is too high during the day and the temperature at night is too low, especially the high temperature in the greenhouse and the low temperature on the ground during the day in winter, and the temperature at the edges of the greenhouse is less than 5 degrees, which greatly affects the greenhouse. production

Ethylene foam boards are also buried around the greenhouse to isolate the heat conduction of the soil inside and outside the greenhouse, thus solving the problem of large temperature difference between day and night and the uneven temperature of the planting soil layer
