Problems solved by technology

[0004] To ensure that the temperature inside the greenhouse is maintained at a stable temperature, temperature control is usually achieved through the cooperation of equipment / facilities such as sunlight, boilers, water curtains or air coolers. This method consumes a lot of energy and requires complex control of equipment.
Some greenhouses use phase change materials to make energy storage modules. Although the problem of high energy consumption is solved, the heat exchange efficiency and structural optimization design of the energy storage modules are not ideal.

Embodiment 1

[0042] Such as Figure 1-3As shown, a phase-change energy storage greenhouse includes a frame and a vault at the top of the frame. The vault includes a south vault 22 on the side close to the sunlight and a north vault 21 on the side away from the sunlight. The vault reaches Diagonal braces 4 are set between the gables on the south side to physically divide the greenhouse into production chamber 31 and temperature regulation chamber 32. Set the angle range, specifically: not lower than the latitude value of the greenhouse location and not higher than 23.5 degrees of the greenhouse location latitude value; the side surface of the diagonal brace 4 facing the temperature adjustment cavity 32 is connected to the heat exchange component 41, and the heat exchange component 41 passes through The pipeline connects the phase change energy storage components located underground in the greenhouse;

Abstract

The invention relates to a phase change energy storage greenhouse and a working method. The phase change energy storage greenhouse comprises a frame and a vault located at the top of the frame. The vault comprises a south vault located on the side close to the sunshine and a north vault located on the side away from the sunshine, inclined struts are arranged between the vault and a south gable, and the sides, facing the south vault, of the inclined struts are connected with heat exchange assemblies. The greenhouse is physically divided into a production cavity and a temperature adjusting cavity by the inclined struts and the heat exchange assemblies, the temperature adjusting cavity is close to the sunshine irradiation side, and a ventilation fan is arranged in the temperature adjusting cavity; a set angle range is formed between the inclined struts and the ground, the angle range A is larger than or equal to X and smaller than or equal to (X+23.5) degrees, and X is the latitude value of the place where the greenhouse is located; and the heat exchange assemblies are connected with a phase change energy storage assembly located under the greenhouse through a pipeline. The phase change energy storage assembly is located under the ground of the greenhouse, the requirement for the structural strength of the ceiling of the greenhouse is reduced, the installation and construction cost is saved, and the phase change energy storage assembly can further utilize the natural heat preservation effect of the underground environment.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouses, in particular to a phase change energy storage greenhouse and a working method. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The greenhouse is an indispensable facility in the industrial planting of crops. The greenhouse adjusts the temperature and humidity inside the greenhouse based on the local weather forecast by collecting indoor and outdoor temperature and humidity, so as to meet the growing environment of the crops, thereby realizing all-weather, off-season industrialized crop production. [0004] To ensure that the temperature inside the greenhouse is maintained at a stable temperature, temperature control is usually achieved through the cooperation of equipment / facilities such as sunlight, boilers, water curtains, or air coolers. Th...
