Greenhouse regulation and control device based on karst cave air and regulation and control method of greenhouse regulation and control device

Abstract

The invention discloses a greenhouse regulation and control device based on karst cave air and a regulation and control method of the greenhouse regulation and control device. The greenhouse regulation and control device comprises a sealed greenhouse body and an air static pressure chamber, wherein the air static pressure chamber communicates with interiors of a karst cave and the greenhouse body respectively; an air supply suction fan, a resistance wire and a dehumidification paper curtain are sequentially arranged at the communicating part of the air static pressure chamber and the greenhouse body; an exhaust fan is arranged on the other side of the greenhouse body. By adopting the greenhouse regulation and control device, exchange of air inside a greenhouse is achieved, and the greenhouse can be proper in temperature and humidity, convenient to control, easy in air exchange, good in ventilation effect, free of boiler, relatively low in energy consumption and free of pollution; moreover, as the air inside the cave is purified by the cave, the air is relatively appropriate to growth of plants inside the greenhouse, injurious insects can be greatly reduced, rice seedlings can grow relatively well, the production efficiency of the greenhouse can be greatly improved, green pollution-free temperature decrease and dehumidification can be achieved, the energy can be effectively saved, an excellent environment protection effect can be achieved, and moreover, the greenhouse regulation and control device has the characteristics of being simple in structure, low in cost and convenient and rapid to maintain.

Description

technical field [0001] The invention belongs to the technical field of greenhouses, and relates to a control device and a control method for a greenhouse based on karst cave air. Background technique [0002] Greenhouse is an essential basic facility for planting and breeding. The current status of regulating the temperature in the greenhouse: 1. To maintain a certain temperature in the greenhouse in winter, a boiler must be used. This method is not suitable for controlling the temperature in the greenhouse. In summer, the temperature can only be lowered by ventilation. The ventilation effect of the greenhouse is poor, the ventilation is inconvenient, and the temperature in the greenhouse is difficult to control. 2. Boilers are mostly used for heating in existing greenhouses. Coal-fired boilers will cause environmental pollution, and the cost of oil-fired boilers is too high. 3. There are also some greenhouses that use heat-absorbing pipes installed underground to form a w...

Problems solved by technology

The current status of regulating the temperature in the greenhouse: 1. To maintain a certain temperature in the greenhouse in winter, a boiler must be used. This method is not suitable for controlling the temperature in the greenhouse

In summer, the temperature can only be lowered by ventilation. The ventilation effect of the greenhouse is poor, the ventilation is inconvenient, and the temperature in the greenhouse is difficult to control.

2. Boilers are mostly used for heating in existing greenhouses. Coal-fired boilers will cause environmental pollution, and the cost of oil-fired boilers is too high

3. There are also some greenhouses that use heat-absorbing pipes installed underground to form a water cycle to obtain energy. This method obtains less heat, and the supply of temperature in the greenhouse is insufficient, and it is difficult to maintain a certain constant temperature.

[0003] In addition, the greenhouse has certain requirements on humidity. If the humidity is too high, it will cause condensation on the leaves of the crops;
