Plant factory based on fan frequency conversion adjustment

Abstract

The invention discloses a plant factory based on fan frequency conversion adjustment. An air mixing air chamber is arranged between crop cultivation chambers and refrigerating and heating equipment, an air outlet of the refrigerating and heating device is in through connection with the air mixing air chamber, the air mixing air chamber is in through connection with crop cultivation chambers on each layer through variable frequency fans, and a plant light supplement lamp, a mist outlet of a humidifier, an illumination sensor, a wind speed sensor and the variable frequency fan which are arranged in the crop cultivation chamber are all in signal connection with a control module in a control chamber, so that the temperature balance in the crop cultivation chamber is realized. According to the plant factory based on fan frequency conversion adjustment, an air mixing channel is additionally arranged between air inlets of the fans and the refrigerating and heating equipment, the variable frequency fans are turned on after the channel is filled with cold air, and therefore it is guaranteed that the fan on the upper layer can further suck enough cold air; and in addition, frequency conversion adjustment is carried out on the fan on each layer in the plant factory through a control system, so that the environment temperature on each layer in the interior of the plant factory can be synchronously regulated and controlled, the temperature difference between the cultivation layers is reduced, the stability of crop quality is kept, and an environment suitable for growth is provided for crops.

Description

Technical field[0001]The present invention relates to a plant factory, and more particularly to a plant-based plant based on a fan-converted regulation.Background technique[0002]Climate abnormalities, water shortages, and growing reductions in land resources are an important factor in the world's food crisis. According to United Nations data, the global population will increase to 9.8 billion in 2050, of which 66% will account for 66%. In order to solve the problem of global food shortage, a new way - "Plant Factory" came into being. Plant Factory consists of a cultivation facility that is thermally and almost sealed similar warehouse structures, including artificial light sources, air conditioning, air circulating fans, carbon dioxide, nutrient supply devices, and environmental regulatory devices. Micro plant plants are widely used in educational institutions, restaurants, office spaces and hospitals, etc., in addition, due to the structural dimensional limitations of micro plant p...
