DETAILED DESCRIPTION

[0021] In order to better understand the purpose, structure and function of the present invention, the present invention is clearly and completely described below with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figure 1 The greenhouse temperature control device shown in the figure comprises: a box body 1, a cold air assembly and a fan 2, wherein the cold air assembly and the fan 2 are located inside the box body 1. A support is provided at the bottom of the box body 1, and a mounting hole is provided on the support. The box body 1 is mounted at a desired position by means of bolts passing through the mounting hole. An air inlet is provided on one side wall of the box body 1 to Figure 1 Based on the direction, the air inlet is opened on the right side wall of the box body 1. The air inlet is equipped with a filter 3, which is opposite the cold air component. After being filtered by the filter 3, the air enters the cold air component inside the box body 1 for cooling. The air outlet is provided on the side wall of the box body 1 opposite the air inlet, that is, the air outlet is provided on the left side wall. The air outlet is equipped with an interface 4, which is used to connect to the membrane cylinder 5. The fan 2 is installed between the air outlet and the cold air component. The fan 2 provides power to draw external air into the cold air component and discharge the air exhausted by the cold air component through the air outlet into the membrane cylinder 5.

[0024] In this embodiment, the cooling air assembly includes a cooler 6 and a condensate collection pan 7. The cooler 6 is opposite the air inlet, with the condensate collection pan 7 located below it. Its inlet pipe 8 and return pipe 9 pass through the side wall of the housing 1. The condensate collection pan 7 is provided with a drain pipe 10 that passes through the side wall of the housing 1. The inlet pipe 8, return pipe 9, and drain pipe 10 all pass through the front side wall of the housing 1. Cold water is introduced into the cooler 6 through the inlet pipe 8, exchanging heat with the gas entering the housing 1, cooling the gas. The cooled gas is then discharged from the air outlet into the membrane cylinder 5 via the fan 2. The water in the gas condenses when it contacts the cooler 6 and falls into the condensate collection pan 7, where it is then discharged through the drain pipe 10.

[0025] In this embodiment, the membrane cylinder 5 is made of PE (polyethylene) plastic and is provided with a plurality of through-holes 11 for supplying air into the greenhouse 14 and regulating the temperature therein. The density of the through-holes in the membrane cylinder 5 increases gradually from one end near the housing 1 to the other, thereby compensating for pressure drop and ensuring uniform air supply. The open end of the membrane cylinder 5 is fitted over the interface 4, which is then fixedly connected to the interface 4 using a wire rope or binding rope.

[0026] In addition, a fixing plate 12 is provided inside the box body 1 . The fixing plate 12 is located between the cold air assembly and the fan 2 and is used for installing the fan 2 .

[0027] A cooling air assembly is installed within housing 1 and used in conjunction with film cylinder 5. This cool air is evenly delivered through the film cylinder 5 to the interior of greenhouse 14, achieving uniform air supply and temperature control for rows 60 to 120 meters long. Furthermore, when a hot fluid is passed through surface cooler 6, the air is heated, achieving a warming effect, making it suitable for use in winter or colder weather.

[0028] Example 2

[0029] The same structures in this embodiment as those in embodiment 1 have the same names, functions and reference numerals, and are not described again here.

[0030] like Figure 2 and Figure 3 As shown, the box 1 is installed in a climate chamber 13, which is located inside a greenhouse 14 and close to the outer wall of the greenhouse 14. Specifically, the side wall of the climate chamber 13 and the outer wall of the greenhouse 14 are the same wall. The covering material of the greenhouse 14 is glass. A plurality of boxes 1 are installed in the climate chamber 13 as needed; the film cylinder 5 passes through one side of the climate chamber 13 and extends into the interior of the greenhouse 14 to the bottom of the cultivation trough 15;

[0031] A vent is provided on the outer wall, a wet curtain window 16 is provided on the outer side of the outer wall, a wet curtain wall 17 is provided on the inner side, and the wet curtain wall 17 is located in the climate chamber 13; the gas enters the air inlet of the box body 1 from the climate chamber 13 through the wet curtain window 16, the vent, and the wet curtain wall 17 in sequence; a top window 18 is provided on the top of the greenhouse 14 for dispersing the gas in the greenhouse 14.

[0032] The external air passes through the wet curtain, through the climate chamber 13, enters the surface cooler 6 to adjust the temperature, is sent into the greenhouse 14 through the membrane cylinder 5, and then dispersed through the top window 18, which can realize the internal and external circulation of air flow and adjust the environmental parameters in the greenhouse 14.

[0033] Furthermore, a partition window 20 is provided at the top of the climate chamber 13. When opened, the partition window 20 communicates with the greenhouse 14. Air in the greenhouse 14 enters the climate chamber 13 through the partition window 20, then enters the surface cooler 6 for temperature adjustment. It is then delivered to the greenhouse 14 via the membrane cylinder 5, enabling reciprocating exchange of air within the greenhouse 14, achieving internal circulation of air within the greenhouse 14 and regulating the environmental parameters of the greenhouse 14.

[0034] During specific use, the wet curtain window 16 and the partition window 20 can be opened proportionally as needed, and the internal and external air are mixed in the climate chamber 13 and then sent into the room through the surface cooler 6 and the membrane cylinder 5 to adjust the indoor ambient temperature and other parameters.

[0035] Furthermore, an inner heat-insulating body 21 and an inner sunshade body 22 are provided on the upper part of the interior of the greenhouse 14 , which are common components of the greenhouse 14 and will not be described in detail here.
