Active solar glass greenhouse based on natural energy intelligent temperature control and operation mode

Abstract

The invention discloses an active solar glass greenhouse based on natural energy intelligent temperature control and an operation mode, and belongs to the technical field of agricultural greenhouses and clean heat supply. Aiming at the problems of great heat and cold supply load, high energy consumption and high energy cost caused by poor heat insulation effect of an enclosure structure of a current greenhouse, a clean heat supply system mode based on natural energy intelligent temperature control is adopted, a brand new embedded pipe type enclosure structure is adopted, low-temperature heat source water of a terrestrial water source is introduced into an embedded pipe, heat dissipation of an external environment is borne by the structure at night in winter, and solar radiation is absorbed to release heat in the daytime in summer, so that the heat and cold supply load is remarkably reduced; a low-temperature distributed terminal device is adopted indoors; the clean heat source system is composed of terrestrial water source heat energy, solar energy, air energy, a heat pump unit and an energy storage tank, the terrestrial water source heat energy is directly supplied to the embedded pipe type enclosure structure, the low-temperature side of a heat pump and a cooling wet curtain, high-temperature heat energy is supplied to the indoor terminal in winter, and the air energy and the solar energy supplement heat for the terrestrial water source in summer. According to the invention, the full-year intelligent, efficient and clean heat and cold supply of the greenhouse is realized.

Description

technical field [0001] The invention relates to an active solar glass greenhouse based on natural energy intelligent temperature control and an operation method, and belongs to the technical field of agricultural greenhouses and clean heating. Background technique [0002] Greenhouses are important infrastructure and efficient production forms in agricultural production, especially in the field of economic crops such as vegetables, fruits, flowers, and medicinals. Among them, a large number of passive solar plastic greenhouses are used in my country, and high-end glass greenhouses are being introduced in recent years. Among them, glass greenhouses in Nordic Netherlands and other countries can have an annual production period of up to 11 months, and the output per mu is extremely high. Take tomato production as an example (the following is an excerpt from the experience of relevant professionals on the Internet): "The yield per mu of tomatoes depends on the species planted and...

AI Technical Summary

Problems solved by technology

[0013] The purpose and task of the present invention is to aim at the main problems of the above-mentioned agricultural greenhouses, especially the high-efficiency glass greenhouses, adopt the above-mentioned latest technological development achievements of clean heating, and combine the actual technical conditions and production operation requirements of agricultural greenhouses to design a brand new one. The integrated technology system and energy system operation mode of the active solar glass greenhouse based on intelligent temperature control of natural energy fundamentally change the existing problem of excessive energy consumption, in order to greatly reduce its energy operating costs, improve the effective time of production operations, Provide basic technical conditions for improving crop yield and economic benefits
