Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams used to illustrate the basic structure, key components and main uses of the present invention, so the embodiments of the present invention are not limited thereto.

[0021] a kind of like figure 1 The shown phase change heat storage device for temperature control in a greenhouse is composed of aluminum alloy paraffin blocks (1), aluminum alloy hanging paraffin box (2), hanging support plate (3), and insulation layer (4). Among them, the aluminum alloy paraffin block (1) has a specification of 390×190×190mm, the cavity shell of the block is made of aluminum alloy, and the paraffin is injected and sealed through the sealing port (7), and is assembled on the inner surface of the north wall of the greenhouse. The specification of the aluminum alloy hanging paraffin b...

Abstract

The invention relates to a phase-change heat storage device for greenhouse temperature control. The phase-change heat storage device comprises an aluminum alloy paraffin block (1), an aluminum alloy hanging paraffin box (2), a hanging support plate (3) and a heat insulation layer (4), the specification of the aluminum alloy paraffin block (1) is 390*190*190mm, a cavity shell of the block is made of aluminum alloys, paraffin is injected into the paraffin block through a packaging opening (7) and sealed, and the aluminum alloy paraffin block is bonded on the inner surface of the north wall of agreenhouse. The specification of the aluminum alloy hanging paraffin box (2) is 240*190*480mm, a cavity shell of the box is made of aluminum alloys, paraffin is injected into the paraffin box throughthe packaging opening (7) and sealed, the paraffin box (2) is placed on the hanging support plate (3) and tied on the upper hanging support plate (3) through a hemp rope (5), and the hemp rope is connected on the aluminum alloy box through a knob (6). The device is based on good phase-change latent heat characteristics of paraffin serving as a phase-change material, heat is absorbed and stored inthe daytime, excessive temperature caused by heat accumulation in the greenhouse is avoided, the temperature is reduced to gradually release heat in the nighttime, heat environments by needed by cropgrowth in the greenhouse are maintained, freezing damage to crops is avoided, renewable solar energy is sufficiently utilized, good indoor thermal environments are created, energy consumption is reduced, artificial heating is decreased, and greenhouse production benefits are improved.

Description

technical field [0001] The invention relates to the field of heat storage and energy saving in facility agriculture, in particular to a phase change heat storage device used for temperature control in a greenhouse. Background technique [0002] Solar greenhouse is the abbreviation of energy-saving solar greenhouse, and it is called greenhouse greenhouse or greenhouse in agriculture. The multi-span greenhouse is an application form of the greenhouse, which connects the original independent single-span greenhouses. Traditional solar greenhouses have a simple enclosure structure and poor thermal insulation performance, especially basically no heat storage performance. In anti-seasonal and anti-regional solar greenhouses, due to strong solar radiation during the day, the temperature inside the greenhouse is high, and ventilation is required to cool down; at night, as the outdoor temperature decreases, the temperature inside the greenhouse will drop sharply, requiring artificial...
