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]In addition, the above three existing greenhouse heating systems do not have the function of heat preservation. The temperature of the water used as the heating transmission medium after starting the heating every night and closing the system in the morning Gradually dissipate, and when the heat preservation curtain is closed at night and the system heating is started again, 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

Abstract

The invention discloses a full-automatic low-energy-consumption warming system of a greenhouse. The full-automatic low-energy-consumption warming system comprises an electric temperature control circulating water pump, a water conveying pipe, heat radiation sheets and an automatic warming device with a heat preservation function, wherein the automatic warming device is provided with a liquid capacity cavity, a water outlet and a water inlet; the water outlet of the automatic warming device, the electric temperature control circulating water pump, the plurality of heat radiation sheets and the water inlet are connected in sequence by the water conveying pipe to form a heat-transfer cycle loop; heat absorption coatings coat the outer parts of the heat radiation sheets. The starting temperature of repeatedly heating a heat transfer medium is very high through the heat preservation function of the automatic 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 system 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 temperature increasing device, in particular to a device for increasing the temperature of a greenhouse. Background technique [0002] The existing warming technologies for greenhouses mainly fall into the following categories: [0003] A. Hot air stove: It is widely used as a greenhouse to increase the temperature. The structure is a coal stove and an iron ventilation pipe. The principle is that the coal furnace burns coal to generate hot air, and the hot air transports heat through the iron pipe to achieve the effect of warming. [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 circulation pump, hot water pipes and cooling fins. The principle is that the boiler burns coal to heat water, uses water as the heat transfer medium, and circulates to the radiator through the circulating pump ...
