Device for stabilizing the thermal conditions in the greenhouse

 

(57) Abstract:

Use: in the plant, and construction of protective soil to create in the greenhouse required for plant microclimate. The device consists of two radiators (1, 2), communicated among themselves and filled with water. Upper radiator (1) is located in the greenhouse above the soil level and the bottom of the radiator (2) - in the soil at a depth of 30 - 100 see the Device has a hole to fill water and is installed in a greenhouse, Conservatory or greenhouse. The upper heat sink (1) towards the bottom (2) is tilted at an angle of 10 - 30o. In the daytime, more warmer, heated water in the upper heat sink (1) and flows by gravity into the lower radiator (2). Due to heat transfer from the latter heats up the soil of the greenhouse, accumulating heat input. At night, cooler period, is the reverse process. Heated soil due to heat transfer gives up heat to water stored in the bottom of the radiator (2). Then the warm water enters the top of the radiator (1) and heats the air in the greenhouse. Thus, the device allows you to mitigate the negative impact on the greenhouse climate of night frosts and high temperature on a hot Sunny day. 2 Il.

The invention of what used to regulate the temperature setting of the climate of the mentioned structures. It is known that for growing vegetables and flowers are widely used hotbeds, greenhouses various designs. And in the process of cultivation often have difficulty in maintaining the desired temperature in the building. This problem occurs also in private households in the absence of staff within a few days. In this case, it is possible not only freezing plants at night frosts, and wilt them in the event of overheating due to high levels of solar radiation in the greenhouse or cold frame in the daytime. To solve this problem were created automatic device for regulating the temperature in the greenhouse (SU, ed.St., 1671194, class A 01 G 9/00, 1989, SU, ed.St., 539557, class A 01 G 9/00, 1975, SU, ed.St., 718053, class A 01 G 9/14, 1978, SU, ed.St., 943449, class A 01 G 9/14, 1980, SU, ed.St., 1702939, class A 01 G 9/14, 1989, SU, ed.St., 1340659, class A 01 G 9/14, 1986).

However, these devices are very energy-intensive and complex.

The closest in technical essence to the invention is a device solar heating system (PR, Sabadi, solar house, - M; stroiizdat, 1981, S. 50 - 51), containing communicated between the upper and lower radiators, placed, respectively, in the room above Patalavaca mode in the room.

To eliminate these disadvantages and have created this invention.

In Fig. 1 shows the device for stabilizing thermal conditions in the greenhouse of Fig. 2 - the device for stabilizing thermal conditions in the greenhouse, with the battery capacity.

Device for stabilizing thermal conditions in the greenhouse contains the upper 1 and lower 2 radiators, communicated to each other via a hollow tube 3. The radiator is filled with coolant, which often use water. The upper heat sink 1 is tilted at an angle of 10 - 30orelative to the bottom of the radiator 2.

On the surface of the heat sink 1, 2 made of heat-exchange fins 4, positioned to maximize the value of the coefficient of heat transfer with the environment. The distance between ribs 4 depends on the size of the radiators and are in the range of 2 to 15 see the Device are made of metal or alloy and set in the hotbed or greenhouse, as shown in Fig. 1 and 2. The upper heat sink 1 is placed above the soil, and the lower radiator 2 is located in the soil at a depth of 30 - 100 see the lower part of the tube 3 can be expanded with the formation of the accumulator tank 5, as shown in Fig. 1 and 2, h is e 6 for the Gulf of liquid coolant, in particular water. One or more devices are placed in the greenhouse during the growing plants.

The device operates as follows.

At night, when frosts, hot day, the ground gives off heat to the lower radiator 2 and heats the upper radiator 1. The heat transfer is carried out both by heat transfer from the metal, and by heat transfer with water, which filled radiators 1, 2, which, when the temperature difference in 5 - 10omoving through the pipe 3 connecting the radiators 1, 2. Heavy cold water goes down and the warmer rises, heating the upper radiator. Due to this and heat transfer from the soil to the air temperature in the greenhouse or greenhouse increases, which contributes to reduce the impact of frost on plants are grown. Conversely, when strong solar radiation during the daytime under film or glass, the temperature can reach 30 - 35oC and more.

The soil temperature at a depth of 50 - 100 cm, no more than 15 - 20oC. during this period, the heated water flows under gravity from the upper 1 lower radiator 2, from which the heated soil in the greenhouse. At the same time more cold water is pushed to the top of the radiator 1 to the device and the number of simultaneously established in the greenhouse of the device may vary within wide limits. To reduce the occupied space in the greenhouse, the device may be used as elements of load-bearing structures of the greenhouse.

The use of this device allows to stabilize thermal regime in the greenhouse, providing mitigation of negative impacts on cultivated plants as night frosts and high solar radiation during daylight hours.

Device for stabilizing thermal conditions in the greenhouse, containing communicated between an upper radiator placed over the soil in the greenhouse, and the lower radiator installed in the ground, characterized in that the lower radiator placed in the soil at a depth of 30 - 100 cm, and the upper heat sink is positioned at an angle of 10 - 30orelative to the bottom.
