Fresh air ventilator for greenhouse plantation

Abstract

The invention discloses a fresh air ventilator for greenhouse plantation. The fresh air ventilator comprises an outdoor exhaust port, a shell, an air purifier, a centrifugal fan, a power supply switch, an outdoor intake port, an electromagnetic valve, a water container, a nozzle, an atomizer, an indoor exhaust hole, a parameter set host machine, a temperature / humidity inductor, an air quality detector, a heat exchanger, a universal wheel and an indoor intake hole. The fresh air ventilator has the following beneficial effects: when the fresh air ventilator is used, outdoor fresh air and indoor exhausted air can perform heat exchange and recovery through the heat exchanger to protect heat in a greenhouse from losing; the air purifier can purify air; outdoor air of the centrifugal fan is forcedly fed indoors, and meanwhile, indoor gas is forcedly exhausted outdoors; the conditions in the greenhouse can be always monitored through the temperature / humidity inductor and the air quality detector thereof; the set atomizer can increase the air humidity as needed; or nutrient solution is sprayed in the air; and the universal wheel is convenient for moving the equipment.

Description

technical field [0001] The invention relates to a capacitor, in particular to a fresh air ventilator for greenhouse planting, and belongs to the technical field of agricultural equipment application. Background technique [0002] With the rapid development of the national economy, modern agriculture has made great progress. Agricultural production is no longer limited by environmental factors such as fields and locations. Solar greenhouses and plastic greenhouses have been generally built across the country according to needs, creating good growth for crops. Environment, with the wide application of agricultural production technologies such as greenhouse planting, industrial seedling raising and facility cultivation, various equipment for greenhouse planting have also been developed, and fresh air ventilators are one of them. Fresh air ventilators It is designed and developed based on the principle of air supply on one side of the airtight room and induction on the other sid...

[0002] With the rapid development of the national economy, modern agriculture has made great progress. Agricultural production is no longer limited by environmental factors such as fields and locations. Solar greenhouses and plastic greenhouses have been generally built across the country according to needs, creating good growth for crops. Environment, with the wide application of agricultural production technologies such as greenhouse planting, industrial seedling raising and facility cultivation, various equipment for greenhouse planting have also been developed, and fresh air ventilators are one of them. Fresh air ventilators It is designed and developed based on the principle of air supply on one side of the airtight room and induction on the other side, and a "fresh air flow field" will be formed indoors. It relies on mechanical air supply and induction to force the formation of a fresh air flow field in the system. , is a new type of environmentally friendly electrical appliance that keeps the indoor air clean and fresh at all times. It is widely used in industrial and agricultural production. However, the traditional fresh air ventilator still has deficiencies in intelligent control, and there are still deficiencies in application and agricultural production. There are still deficiencies in the monitoring of temperature, humidity and air quality, and there is still insufficient heat exchange in the application and greenhouse planting, which may easily cause heat loss in the greenhouse, and air humidification still needs to be improved
