Description

Vegetable greenhouses controlled by solar energy

technical field

The utility model belongs to the field of vegetable cultivation, in particular to a temperature control device in a vegetable greenhouse.

Background technique

In many areas of our country, vegetable greenhouses are used to cultivate various vegetables. This kind of greenhouse is composed of a greenhouse frame, a plastic film covered on the greenhouse frame and a thermal insulation quilt. The plastic film has the characteristics of light transmission and heat preservation. During the day, sunlight shines directly into the greenhouse through the plastic film, and the temperature in the greenhouse is kept relatively high. And sufficient sunlight is conducive to the photosynthesis of vegetables in the greenhouse. Due to the good sealing performance of the plastic film, there is also a certain humidity in the greenhouse, which is beneficial to the growth of vegetable plants. At night, when the outside temperature drops, stretching the thermal insulation quilt on the plastic film can keep the temperature of the greenhouse from being too low at night, and then roll up the thermal insulation quilt during the day. For the heat preservation of the vegetable greenhouse, pile up the soil on one side of the greenhouse. This not only wastes soil, but also takes up a lot of land space. In order to solve this problem, the applicant invented a brand-new vegetable greenhouse, and built a building on one side of the greenhouse for living, so that cultivating vegetables and living are integrated. It not only saves land, but also embodies the innovation of urban agriculture and rich pastoral scenery. It is an excellent place for urban people to relax. However, if the vegetable greenhouse is used as a residence, it is necessary to solve the problem of heating in winter or enjoying the cool in summer. Heating in winter wastes a lot of energy by heating, and vegetable greenhouses are generally located in remote places, so central heating cannot be implemented. If you rely on coal-burning stoves for heating, you will not only waste a lot of coal resources but also pollute the environment. In addition, using air conditioners to enjoy the cool in summer also consumes a lot of electricity.

Utility model content

The technical problem to be solved by the utility model is to provide a vegetable greenhouse that uses solar energy to control the temperature, and does not need to consume extra energy for heating and cooling when living in winter or summer.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: design a vegetable greenhouse utilizing solar energy temperature control, including a greenhouse frame, a living building is built on one side of the greenhouse frame, and a pool is built on the ground, which is characterized in that the roof of the living building is Place the solar heat collector, the hot water pipe and cold water pipe of the solar heat collector are respectively connected to the radiator, the radiator is located in the room of the residential building, the hot water pipe of the solar heat collector is connected to the pump; the water inlet pipe and the return pipe are inserted into the pool The water pipe, the water inlet pipe and the return water pipe are all connected with solenoid valves, the water inlet pipe is connected with the cold water pipe, the return water pipe is connected with the hot water pipe, the cold water pipe between the water inlet pipe and the solar collector is connected with a solenoid valve, and the pump is connected with the solar collector. A solenoid valve is connected on the hot water pipe between the heat collectors.

The radiator of the utility model can be a cooling fin, and the cooling fin is fixed on the wall body in the room. This is conventional heating.

The radiator of the present utility model can also be a radiating pipeline, and the radiating pipeline is laid under the floor of the room. This is the ground heating method.

Because the temperature of the hot water pipe is very high, a certain air pressure is generated in it, and for pressure relief, the hot water pipe of the solar collector is connected with an exhaust valve.

The beneficial effect of the utility model is that a water source and a set of pipeline structure are adopted, and the circulating water is heated by solar energy in winter, thereby saving energy. When used in summer, it can be used as a water air conditioner by taking advantage of the low temperature of the ground.

Detailed ways

Embodiment one

As shown in Figure 1, a solar heat collector 2 is installed on the roof of the residential building. In Fig. 2, the hot water pipe 17 and the cold water pipe 3 of the solar heat collector 2 communicate with the heat dissipation pipes 10 and 12 respectively, and the heat dissipation pipes are laid under the floor of the room in the building, which is the floor heating method. The hot water pipe 17 of the solar heat collector 2 is connected with the water pump 7; the water inlet pipe 5 and the water return pipe 14 are inserted into the pool 13, and the water inlet pipe 5 and the water return pipe 14 are connected with the solenoid valve 6 and the solenoid valve 15 respectively, and the water inlet pipe 5 and the water return pipe 14 are respectively connected with each other. The cold water pipe 3 is connected, and the return pipe 14 is connected with the hot water pipe 17; the cold water pipe 3 between the inlet pipe 5 and the solar collector 2 is connected with a solenoid valve, and the hot water between the water pump 7 and the solar collector 2 The solenoid valve is connected on the pipe 17. The hot water pipe 17 is connected with the exhaust valve 1 .

The working process of utilizing solar energy for heating is set forth below.

Close electromagnetic valve 15, open electromagnetic valve 6,4, open water pump 7, cold water flows into solar collector 2 li through water inlet pipe 5, cold water pipe 3, and cold water is heated to hot water. When the water is full of the solar heat collector, close the solenoid valve 6, open the solenoid valves 16, 8, 9, 11, the hot water flows into the solar heat collector 2 through the cold water pipe 3 after passing through the hot water pipe 17 and the heat dissipation pipes 10 and 12 , to complete a heat exchange process. Such continuous circulation can keep the room warm. Wherein the radiating pipes 10, 12 are laid under the floor of the room, which is the floor heating method. Each radiating pipe can be controlled respectively by electromagnetic valve whether to enter water, and the quantity of radiating pipe is more or less, decides according to specific conditions. When the temperature is comfortable without solar heating, the water in the solar collector 2 is drained, and the solenoid valve 6 and the water pump 7 are closed.

The working process when using the pipeline with the above-mentioned structure to cool down as a water air conditioner is set forth below.

Close the solenoid valves 4 and 16, open the solenoid valves 6 and 15, and turn on the water pump 7. After passing through the water inlet pipe 5, heat dissipation pipes 10 and 12, the cold water flows into the pool 13 after passing through the hot water pipe 17 and the return pipe 14 to complete a water cycle. process. Because the radiating pipes 10, 12 are laid under the floor of the room, the water temperature in the radiating pipes is very low due to the influence of ground air, and it completes a heat exchange process with the water flowing out from the pool. Repeating this cycle can keep the room at a lower temperature.

Pool 13 can be underground well or fish pond etc. If an underground well is used, the cooling effect of the room is better in summer due to the lower temperature of the well water. If a fish pond is adopted, the fish pond can be used for raising fish, and can be used as a water source for heating or enjoying the cool, which can serve multiple purposes.

According to needs, the electromagnetic valve 16 that controls hot water can be connected with light sensor. When night falls, after the light sensor detects the light value, the signal is transmitted to the solenoid valve 16, and the solenoid valve 16 can be opened, and the room heating starts.
