Problems solved by technology

[0007] A. Hot air stove: Although the cost is the cheapest, it has high energy consumption, high pollution, and requires people to add coal regularly. At the same time, because of the structure that the hot air dissipates heat through the hot air pipe, the heat near the coal stove is high, and the heat at the end is low. There is a problem of uneven heating and increasing
[0008] B. Coal-fired heating boiler: the advantage is that the heating is uniform, but the cost is expensive, the energy consumption is medium, the pollution is large, and people need to add coal regularly, it is difficult to popularize and apply in a large area
[0009] C. Electric heating boiler: the advantages are no pollution and uniform heating, but the cost is the highest and the energy consumption is high. It is only used for demonstration in agricultural demonstration gardens, and it is difficult to popularize and apply it on a large scale.
[0010]Moreover, the above three existing greenhouse warming methods and systems do not have the function of heat preservation. After the heating is started every night and the system is closed in the morning, the water used as the heating transmission medium The temperature gradually dissipates, and when the heat preservation curtain is closed at night and the system is started again for heating, the water temperature has been greatly reduced compared with the end of heating in the morning, and the initial temperature of the transmission medium is lower for reheating, resulting in greater energy loss

Embodiment 1

[0071] Embodiment 1: The full-automatic low-energy-consumption warming method for greenhouses provided in Embodiment 1 includes the following steps:

[0072] Installation steps: install the heating system, such as figure 1 As shown, the warming system is a fully automatic low-energy-consumption warming system for greenhouses, which includes a warmer, an electric temperature-controlled circulating water pump 2, a water pipe 3, and a heat sink 4. The warmer is an automatic warmer 1, and includes a stainless steel shell and a stainless steel inner shell. The stainless steel inner shell is a liquid volume cavity. The stainless steel shell and the stainless steel inner shell are filled with an insulation layer processed by foaming technology. The automatic warmer 1 is provided with a water outlet and a water inlet communicating with the liquid volume cavity; the water outlet of the automatic warmer 1, an electric temperature-controlled circulating water pump 2, a number of cooling fins...

Embodiment 2

[0088] Embodiment 2: The steps are basically the same as those in embodiment 1, and the similarities will not be repeated, the difference is:

[0089] In the installation step: the warming system is a fully automatic low-energy warming system for greenhouses, and its structure is basically the same as the warming system in Example 1, and the similarities are not repeated here. The difference is: The first temperature sensor includes a room temperature sensor (not shown in the figure) arranged outside the stainless steel housing of the automatic warmer 1 for collecting room temperature in the shed, and a room temperature sensor (not shown) arranged in the liquid volume cavity of the automatic warmer 1 A water temperature sensor (not shown in the figure) that collects the water temperature in the volume cavity; the second temperature sensor includes a room temperature sensor (not shown in the figure) that is arranged outside the electric temperature-controlled circulating water pump...

Embodiment 3

[0101] Embodiment 3: The steps are basically the same as those in embodiment 1, and the similarities will not be repeated, the difference is:

[0102] In the installation step: the warming system is a greenhouse full-automatic low-energy warming system, and its structure is basically the same as that of the warming system in Example 1. The similarities are not repeated here, the difference is: this implementation In Example 3, there are 12 aluminum alloy fins connected in sequence, and the volume of the liquid volume cavity is 150L. The first temperature sensor only includes a room temperature sensor arranged outside the stainless steel housing of the automatic warmer 1 and used to collect the room temperature in the shed; the second temperature sensor only includes a room temperature sensor arranged outside the electric temperature-controlled circulating water pump 2 A room temperature sensor for the room temperature in the collection shed. Of course, the first temperature sens...

Abstract

The invention discloses a full-automatic low-energy-consumption warming method of a greenhouse. The full-automatic low-energy-consumption warming method comprises the following steps: mounting a warming system, setting, keeping heat, heating by solar energy, electrically heating, and carrying out heat-transfer cycle. The warming system comprises a warming device with heating and heat preservation functions, an electric temperature control circulating water pump and a plurality of heat radiation sheets coated with heat absorption coatings, wherein the warming device, the electric temperature control circulating water pump and the heat radiation sheets are connected in sequence to form a heat-transfer cycle loop. The starting temperature of repeatedly heating a heat transfer medium is very high through the heat preservation function of the warming device and the heat absorption function of the heat radiation sheets coated with heat absorption materials, so that the energy consumption is extremely saved, the energy efficiency is high and the warming cost is saved. Overall, the full-automatic low-energy-consumption warming method has the advantages of energy conservation, environment friendliness and no pollution, uniformity in warming, low cost and high energy efficiency, full-automatic warming, water conservation, and flexibility and convenience for setting, and can be widely popularized and applied.

Description

Technical field [0001] The invention relates to a method and device for increasing temperature, in particular to a method and device for increasing the temperature of a greenhouse. Background technique [0002] The existing greenhouse heating technologies mainly include the following categories: [0003] A. Hot blast stove: It is widely used as a greenhouse to increase temperature, and its structure is coal stove and iron sheet ventilation pipe. The principle is that hot air is produced by burning coal in a coal furnace, and the hot air transports heat through iron pipes to achieve the effect of heating. [0004] B. Coal-fired heating boilers: generally used by agricultural cooperatives with certain economic conditions. The structure includes a coal-fired high-pressure boiler, a hot water circulating pump, a hot water pipe and a heat sink. The principle is that the boiler burns coal to heat water, and uses water as the heat transfer medium to circulate to the radiator through a ci...
