Winter solar greenhouse dehumidification device and method for dehumidifying greenhouse by using same

Abstract

The invention discloses a winter solar greenhouse dehumidification device and a method for dehumidifying a greenhouse by using the same, and belongs to the technical field of agricultural engineeringequipment. The device of the invention mainly monitors the temperature and humidity changes in the greenhouse in real time through a humiture sensor, adopts a corresponding dehumidification managementmode, and uses a total-heat recovery heat exchanger to increase the fresh air temperature of introduced outdoor air and reduce the relative humidity in the greenhouse so as to reduce the air humidityin the greenhouse in winter without reducing the air temperature. The method of the invention ensures that the temperature in the greenhouse is not reduced while reducing the humidity of the air to meet the demand for normal growth of crops. The device of the invention is simple, low in cost and good in running effect, energy consumption mainly comes from electric energy consumption when a fan and an electric heater work, and the device has the characteristics of energy saving and practicality. According to the method of the invention, the temperature and humidity are monitored in the greenhouse in real time, and the monitoring and adjustment process is in all automatic control and does not have cumbersome manual operation, thereby greatly saving labor.

Description

technical field [0001] The invention belongs to the technical field of agricultural engineering equipment, and in particular relates to a winter solar greenhouse dehumidification device and a greenhouse dehumidification method thereof. Background technique [0002] When the solar greenhouse is in production in winter, the indoor low temperature and high humidity environment makes the crops prone to diseases and affects the yield and quality of products. Therefore, it is imperative to improve the air humidity environment in the greenhouse. [0003] At present, in the actual production of solar greenhouses in my country, the commonly used dehumidification methods are mainly to open the top window or side window for natural ventilation, or assist a simple exhaust fan to force the indoor air out of the room to reduce the humidity in the greenhouse. However, when opening windows or forced ventilation, it will inevitably bring about the problem of lowering the temperature in the g...
