Method for controlling temperature and humidity in edible mushroom greenhouse

Abstract

Disclosed is a method for controlling the temperature and humidity in an edible mushroom greenhouse. A data detecting end and a data processing end work together to complete gradient control on a first-level control system and a second-level control system, so as to control the temperature and humidity in a greenhouse. The data detecting end is provided with a humidity sensor arranged in the greenhouse, a first temperature sensor arranged in the greenhouse, and a second temperature sensor arranged outside the greenhouse. The data processing end is provided with a temperature calculation modeland a humidity calculation model. The first-level control system is provided with a main control system which is composed of a first heat exchanger, a humidifier, a second heat exchanger, a gas-liquidseparator and a compressor, and an auxiliary control system which is composed of a turbulent heat recovery device. The second-level control system is provided with a heat exchange system which is composed of a water surface air cooler. According to the method for controlling the temperature and humidity in an edible mushroom greenhouse of the invention, different control modes are set to adapt tothe environments required in different growing periods, and efficient energy saving and maximum utilization of resources are achieved for the setting of corresponding control mechanisms.

Description

technical field [0001] The invention belongs to the field of crop growth environment regulation, and in particular relates to a temperature and humidity control method for edible mushroom greenhouses. Background technique [0002] Greenhouse cultivation of edible fungi is a traditional planting project in my country. Now the domestic and foreign markets are in great demand, and it has become the main project for my country's agricultural export to earn foreign exchange. The current method of processing the environmental space of the greenhouse is mainly to cool down with water curtains in summer. However, when the ambient temperature is high, this method cannot reach the ambient temperature range required for the growth of edible fungi. Therefore, in the hot summer, many edible fungus growers choose to stop planting, resulting in a shortage of edible fungi in the market. In winter, coal stoves are used for heating, which is contrary to the country's major environmental prot...
