Temperature and humidity regulation system for vegetable greenhouse

Abstract

The invention discloses a temperature and humidity regulation system for a vegetable greenhouse. The temperature and humidity regulation system comprises a plurality of temperature and humidity regulating machines which are scattered and arranged or slidably mounted on a greenhouse frame, and each humidity regulating machine comprises a liquid pump for sucking a methanol water material, a reformerfor heating, gasifying and separating the methanol water material, a fuel cell for receiving and separating hydrogen gas, outputting battery residual gas and generating electric power, a gas mixing blower for receiving separated residual gas and the battery residual gas, a fan for injecting external gas to the gas mixing blower, a controller separately and electrically connected with the air mixing blower, the fan and an atomizer, and a temperature and humidity sensor connected with the controller. Each temperature and humidity regulating machine is individual and can be freely scattered andarranged according to the requirements, so that the environmental temperature and humidity of the greenhouse can be regulated safely in an energy saving mode; stepless speed regulation can be realizedin a regulation process, and the temperature and humidity regulating machines can slide on the rails back and forth, so that the heating of the space of the greenhouse area is more uniform, and the reciprocating sliding does not need external power supply.

Description

technical field [0001] The invention relates to a vegetable greenhouse, in particular to a temperature and humidity regulating system for a vegetable greenhouse. Background technique [0002] At present, greenhouses are often built in agricultural production, and crops are grown in the greenhouses, including the cultivation of fungus crops. Generally, the roof of the greenhouse uses a transparent film to block the cold current from the outside and absorb the sunlight, thereby forming a greenhouse effect in the greenhouse. However, when there is no sunlight or the sunlight is weak, even if the roof is thickened, it still cannot guarantee The temperature inside is suitable for the growth needs of vegetables. It will cause winter crops to freeze to death, making it impossible to continue agricultural production. For this reason, wires can be arranged in the greenhouse to generate heat energy by means of electric heating for the needs of crops. However, there are defects such...

AI Technical Summary

Problems solved by technology

However, there are defects such as heavy workload, high energy consumption, inability to arrange and adjust at will, and safety risks in wiring.

In addition, the dry environment is not suitable for the growth of vegetables and other crops, especially mushroom crops need a humid environment to grow

In the fungus crop greenhouse, since it is necessary to create a humid environment in the greenhouse for the growth of the fungus crops, the crops are usually sprayed with water directly by manual work, which is labor-intensive, and the water is unevenly received, and the water falls on the roots to soak. The increase in air humidity is not obvious, which is not conducive to crop growth

The use of artificial atomization to spray water vapor is extremely intensive, difficult to achieve industrialization, low operating efficiency, high crop costs and high prices
