Southern-northern solar greenhouse for energy collection and thermal storage

Abstract

The invention relates to the technical field of facility agriculture, and discloses a southern-northern solar greenhouse for energy collection and thermal storage. The southern-northern solar greenhouse comprises a framework, greenhouse films, thermal preservation quilts, a rear wall, end walls and thermal collecting rooms, the rear wall extends in the east-west direction, and the end walls are arranged at the two ends of the rear wall. The framework is arranged on the rear wall and extends in the south direction and the north direction respectively, the films cover the framework, and a southern greenhouse body and a northern greenhouse body are formed. The thermal preservation quilts cover the greenhouse films. The rear wall is provided with the thermal collecting rooms. Each thermal collecting room comprises two side walls, a thermal collecting wall attached to the northern ends of the side walls and a light-transmitting plate attached to the southern ends of the side walls. Northern cold air inlets are formed in the lower portions of the thermal collecting walls, northern hot air outlets are formed in the upper portions of the thermal collecting walls, southern cold air inlets are formed in the lower portions of the thermal collecting rooms, and southern hot air outlets are formed in the upper portions of the thermal collecting rooms. The thermal storage and energy collection are carried out in the northern greenhouse body through the thermal collecting rooms in the daytime, the greenhouse bodies are covered with the thermal preservation quilts at night, thermal losses of the air outlets are reduced, the diurnal temperature of the southern greenhouse body and the diurnal temperature of the northern greenhouse body at winter are improved, and the yield of crops is improved.

Description

technical field [0001] The invention relates to the technical field of facility agriculture, in particular to a north-south bidirectional solar greenhouse for energy collection and heat storage. Background technique [0002] The energy-saving solar greenhouse with energy collection and heat storage is a new type of greenhouse developed with the modernization of agriculture and the structural adjustment of rural planting. In the past 20 years, the cultivated area of ​​protected horticulture in my country has exceeded 3.8 million hm 2 , an increase of nearly 500 times compared with 1980, the total area is the largest in the world; the per capita area of ​​facility gardening in the country is 29m2 2 , 40% of the annual per capita consumption of vegetables is provided by protected cultivation. The development of protected horticulture has basically solved the problem of insufficient supply of vegetables for a long time in my country, and achieved a balanced supply of vegetable...

AI Technical Summary

Problems solved by technology

[0004] In northern my country, the sun tends to the south, and the general greenhouse only builds a scaffold facing the south. The wind during the day will cause temperature loss and reduce the utilization rate of light and temperature. The north side of the greenhouse is piled with soil to keep the heat, which makes the land utilization rate low.

The lack of heat preservation and energy storage equipment, poor heat preservation and heat storage performance, and low environmental control level in the greenhouse have resulted in the long-term exposure of facility vegetables to adverse environments such as low temperature, low light, and high humidity, or sub-optimal environments.
