Description

TECHNICAL FIELD

[0001] The utility model relates to a temperature control technology field of germination accelerating chamber, specifically relates to a temperature control facility of small germination accelerating chamber. BACKGROUND

[0002] The existing temperature control facility scheme of small germination accelerating chamber adopts the variable refrigerant flow multi-connected air conditioning system, and the air conditioning indoor unit in the variable refrigerant flow multi-connected air conditioning system is installed in the germination accelerating chamber in the form of hoisting or landing. After the fan of the air conditioning indoor unit operates, indoor air flows through the return air inlet of the air conditioning indoor unit and is sent into the indoor from the air outlet, so that the air circulation in the germination accelerating chamber is realized. At the same time, the air is indirectly heat-exchanged with the refrigerant during the air entering the air conditioning indoor unit, so that the temperature is reduced and the air is sent into the indoor, thereby eliminating the indoor residual heat and finally maintaining the required indoor temperature.

[0003] The existing temperature control facility of the germination accelerating chamber has the following problems:

[0004] The temperature in the internal space of the germination accelerating chamber is not uniform in the upper and lower parts: the air supply and return form of the hoisting or landing air conditioning indoor unit is upper supply and upper return or lower supply and lower return, the air flow of the hoisting air conditioning indoor unit is basically circulated in the upper part of the germination accelerating chamber, and the air flow of the landing air conditioning indoor unit is basically circulated in the lower part of the germination accelerating chamber. As can be seen, the air supply and return of the indoor unit of the two forms cannot form good air flow organization, so that the temperature of each point in the indoor space is uniform.

[0005] Some plants are helpful for germination when the diurnal temperature difference is large, but this requirement cannot be met: the variable refrigerant flow multi-connected air conditioning system is mainly applied to places where personnel exist and cooling is required, so that the indoor set temperature cannot be generally lower than 16 degrees from the energy saving and comfort consideration, which leads to that the air conditioning system has certain limitations when being applied to the germination accelerating chamber. For example, when some plants need the germination accelerating chamber to simulate a lower temperature environment at night, the air conditioning system cannot make the germination accelerating chamber reach the required low temperature.

[0026] The features and performances of the utility model will be further described in detail in combination with the embodiments.

[0027] Please refer to Figures 1-3 , a temperature control facility of a small germination accelerating chamber, such as Figure 1As shown, the top and opposite sides of the germination chamber are provided with the air duct sandwich plates 11 parallelly arranged in the germination chamber body plates 12. Figure 2 As shown, the air duct sandwich plates 11 form the top air duct sandwich and the two side air duct sandwiches with the top and two side germination chamber body plates 12 respectively; the center of the top air duct sandwich plate 11 is provided with the double-side air outlet type cold air machine 3, and the germination chamber is provided with the condensing unit 1 outside; the PTC heating wire 14 is arranged at the air outlet of the double-side air outlet type cold air machine 3, the double-side air outlets of the double-side air outlet type cold air machine 3 are located at the two ends of the air duct sandwich, and the air return port is located in the germination chamber; the two back sides of the double-side air outlet type cold air machine 3 are respectively towards the two side air duct sandwiches.

[0028] The air guide aluminum plates 10 are arranged on the two side air duct sandwich plates 11; when the temperature needs to be controlled, the double-side air outlet type cold air machine 3 sucks the air in the germination chamber from the bottom air return port, sends it into the top air duct sandwich and the two side air duct sandwiches through the air outlet, uniformly sends it into the germination chamber through the air guide aluminum plates 10, and finally is sucked back by the air return port of the double-side air outlet type cold air machine 3 after the cold and hot exchange with the inside of the germination chamber, so as to complete the air circulation.

[0029] The length of the two side air duct sandwich plates 11 is the same as the length of the two side germination chamber body plates 12, but the height and width of the two side air duct sandwich plates 11 are different from the height and width of the two side germination chamber body plates 12, the thickness of the two side air duct sandwich plates 11 is 50mm, and the height is 2900mm, the thickness of the two side germination chamber body plates 12 is 100mm, and the height is 3500mm. The height of the two side air duct sandwich plates 11 plus the thickness of the air duct sandwich is less than the height of the two side germination chamber body plates 12. The cross-sectional size of the top air duct sandwich plate 11 is less than the cross-sectional size of the top germination chamber body plate 12. The spacing between the four sides of the top air duct sandwich plate 11 and the four sides of the top germination chamber body plate 12 is equal to the width of the air duct sandwich. The air duct sandwich plate 11 adopts a true gold plate color steel sandwich plate, and the germination chamber body plate 12 adopts a polyurethane double-sided color steel sandwich plate.

[0030] As shown in Figure 3 The air guide aluminum plate 10 is the same width and height as the germination bed 4 in the germination chamber. The edge of the air guide aluminum plate 10 is provided with a humidifying pipe 9 and a humidifying nozzle 5. The humidifying pipe 9 and the humidifying nozzle 5 are connected with the high-pressure micro-fog humidifying machine 2 to humidify the germination bed 4 in the germination chamber.

[0031] The other opposite two side germination chamber body plates 12 perpendicular to the two side air duct sandwich plates 11 are respectively provided with the fresh air wall type fan 6 and the exhaust air wall type fan 7. The other opposite two side germination chamber body plates 12 are respectively provided with the heat preservation sliding door 13 and the air curtain machine 8.

[0033] Working principle: By setting the air supply interlayer, the direction of air flow is changed, the treated air is sent to the lower part of the germination chamber, and then backflows to the cold air fan from bottom to top. The air guide aluminum plate 10 is arranged on the interlayer plate 11 of the two side air ducts, the air supply area is artificially enlarged, and the air supply mode of low air speed, low turbulence degree and small temperature difference is formed.

[0034] The air sent into the room is first uniformly distributed at the bottom, then flows to the heat source (germination lathe 4 or lamp strip) to form a hot air flow in the form of smoke plume flowing upward, and forms a stagnation layer in the upper space of the room. The excess heat in the room is discharged from the cold air fan return air opening arranged above the stagnation layer, then the air flow organization of side sending and upper backflow is formed, and the temperature uniformity in the germination chamber is greatly improved.

[0035] Finally, according to the temperature value obtained by the internal sensor of the germination chamber environment, it is judged whether the temperature in the germination chamber is uniform, so as to control the start and stop of the circulating fan of the cold air fan.

[0036] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the protection scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the technical scheme concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application.
