Problems solved by technology

In order to reduce the temperature and humidity in the greenhouse during the high temperature period during the day, external shading and forced ventilation or natural ventilation are currently used to exchange gases inside and outside the greenhouse, thereby eliminating excess water vapor and heat in the greenhouse, which has caused water resources. waste; and during the low temperature period at night, heating measures are required to prevent the temperature in the greenhouse from being too low

Embodiment 1

[0044] like figure 1 shown. An integrated control device 25 for light and hot water in a greenhouse includes a sunshade condensate panel 1 arranged on the top of the cavity of the greenhouse 22 .

[0045] like Figure 1 to Figure 4 As shown, specifically, the sunshade condensate panel 1 is disposed obliquely on the top of the cavity of the greenhouse 22 , for example, the top of the greenhouse 22 may be configured with an inclined roof 23 , and the sunshade condensate panel 1 is disposed below the top cover 23 . Wherein, the sunshade condensing plate 1 is made of a highly light-transmitting material and has a cavity 2 opened therein. In order to balance the temperature in the greenhouse 22, the control device 25 also includes an energy supply system 5 and a heat dissipation device 6. The energy supply system 5 can inject a cold source into the cavity 2, so that the temperature of the greenhouse 22 is lowered; the energy supply system 5 The heat source can also be delivered ...

Embodiment 2

[0054] A method for integrated control of light and hot water in a greenhouse, comprising the integrated control device of light and hot water in a greenhouse in Embodiment 1, and further comprising the following steps:

[0055] S1. When the sunlight is too strong during the day to illuminate the greenhouse, control the energy supply system to inject the cold source into the cavity of the sunshade condensate plate to reduce the light intensity entering the greenhouse. During this period, the cavity is The cold source heated by sunlight is returned to the energy supply system for heat storage. At the same time, when the air in the greenhouse contacts the sunshade condensate panel with a lower temperature, moisture will be condensed on the surface of the sunshade condensate panel. Water is collected and reapplied for irrigation;

[0056] S2. When the temperature in the greenhouse is low, the energy supply system is controlled to transmit the stored heat to the heat dissipation d...

Embodiment 3

[0059] A greenhouse, including the greenhouse light and hot water integrated control device in the first embodiment.

[0060] The greenhouse of this embodiment can realize the integrated control of light and hot water through the control device, and can realize the recycling of water in the greenhouse while regulating the temperature in the greenhouse, and the use reliability of the greenhouse is high.

Abstract

The invention discloses a greenhouse light and hot water integrated regulation and control device and method and a greenhouse. The regulation and control device comprises a sunshade water condensation plate arranged at the top of a greenhouse cavity, a cavity is formed in the sunshade water condensation plate, the sunshade water condensation plate is further provided with a water inlet and a water outlet which are both communicated with the cavity, and the greenhouse light and hot water integrated regulation and control device further comprises an energy supply system and a heat dissipation device; the energy supply system can inject a cold source into the cavity through the water inlet, the energy supply system can also convey a heat source to the heat dissipation device, the heat dissipation device can dissipate heat of the heat source into the greenhouse, and when the surface temperature of the sunshade water condensation plate is lower than the dew point temperature of air in the greenhouse, moisture in the air can be condensed on the surface of the sunshade water condensation plate, so that the moisture in the greenhouse can be dissipated. The water can be recycled, such as re-applied to irrigation of greenhouse plants. The regulation and control device can realize cyclic utilization of moisture in the greenhouse while shading and cooling the greenhouse.

Description

technical field [0001] The invention relates to the technical field of greenhouses, and in particular, to a greenhouse light and hot water integrated control device, method and greenhouse. Background technique [0002] Greenhouse is the main part of my country's facility agriculture. It can provide growth period and increase yield in seasons that are not suitable for plant growth. It has played a huge role in ensuring the annual balanced supply of vegetables, increasing employment and increasing income. [0003] In some areas of my country, such as Xinjiang, there is sufficient light during the day, which is very suitable for the growth of fruits and vegetables, and the temperature in the enclosed greenhouse space rises rapidly, so cooling measures are often required, but the temperature drops sharply at night, often requiring additional heating . In addition, the water consumption of crops in the greenhouse is extremely high. For example, the daily water consumption of a s...
