Problems solved by technology

[0007] These types of heating heat sources have high energy consumption, high pollution, and a large difference between the energy consumed and the heat output, which wastes resources. At the same time, more equipment is required, resulting in a large footprint, poor stability, and inconvenient maintenance. Most of them are no longer available. It meets the needs of national strategic planning and crop growth, and the energy efficiency utilization rate is too low
Although external radiators, fans, wind disks, etc. can control and increase the air temperature, they cannot increase the temperature required by the root system of the crops, resulting in poor growth of the crops, making it impossible for the crops to reach the standard and yield in a timely and reliable manner, which also causes most of the greenhouses to fail in winter. is idle

Embodiment Construction

[0027] The present invention will be further explained below in conjunction with the accompanying drawings.

[0028] The main improvement technical points of this embodiment are as follows:

[0029] 1. The first integrated solar heat collection, heat storage, and heat supply system and built-in installation technology;

[0030] 2. Adopt a new type of greenhouse planting ground heating circulation system, root and temperature dual control technology;

[0031] 3. It integrates heat collection, heat storage and heat supply, and can also integrate intelligent temperature control technology by using the current information technology system;

[0032] 4. The greenhouse operates independently without secondary heating pipe network; the service life is as long as 12 years;

[0033] 5. The heat collector is installed in the greenhouse without heat preservation and antifreeze;

[0034] 6. The system can be started 35-45 days before heating to preheat the deep soil and store energy in...

Abstract

The invention belongs to the technical field of solar heat utilization, and particularly relates to a greenhouse heating system. The greenhouse heating system comprises a heat storage system, a circulating system, a heat exchange system and a heat collection system which are sequentially connected to form a closed loop, and the heat exchange system is installed in soil of a greenhouse. The system can utilize solar energy to supplement root system heat and utilize the root system heat to supplement air heat; the system can not only meet the temperature required by a root system, but also meet the temperature required by air; and the system realizes efficient utilization and flexible allocation of heat, greatly saves energy consumption, and makes up for the defect that a traditional heating system can only increase air temperature.

Description

technical field [0001] The invention belongs to the technical field of solar heat utilization, and in particular relates to a greenhouse heating system and a heating method. Background technique [0002] my country's protected agriculture started late, but developed rapidly, mainly in the form of glass greenhouses, ordinary plastic greenhouses, and plastic solar greenhouses. [0003] The frame of the glass greenhouse is mainly made of galvanized steel pipes, the frame of doors and windows and the roof ridge are mainly made of aluminum alloy, and the main cover material is transparent glass. Judging from the current production status of glass greenhouses, installation and maintenance are generally inconvenient and operating costs are high. Many of them are used for planting and ornamental demonstration in cultivating flowers, vegetable seedlings and agricultural scientific research. [0004] Ordinary plastic greenhouses and plastic solar greenhouses are widely used in the n...
