Heat-storage, heat-release, dehumidification, ventilation and sterilization type solar greenhouse regulating and controlling system

Abstract

The invention discloses a heat storage, heat-release, dehumidification, ventilation and sterilization type solar greenhouse regulating and controlling system, and belongs to the technical field of agricultural facilities. The system has four functions of heat storage and release, dehumidification, ventilation and sterilization. After a water pump is used for making water in a water tank to absorb heat reflected from a light condensation plate to a heat collecting pipe, the heat is transferred to water in the water tank and a coil pipe, and heat storage is achieved; when the temperature in a greenhouse is low, the water pump is used for making heat of the water in the water tank released to the greenhouse through a water pipe and a radiator to improve the temperature in the greenhouse, and heat release is achieved; a compressor is used for refrigeration, and wet air in the greenhouse is dehumidified through a fan and an evaporator, heated in a condenser, then heated to the required temperature through an electrical heater and finally sent into the greenhouse through an air pipe, and therefore dehumidification is achieved; ventilation is achieved though vent holes inside and outside the greenhouse under the action of a fan and an adjusting air valve; sterilization is achieved through ultraviolet sterilizing lamps during dehumidification or ventilation. The system can improve the utilization rate of solar energy and enhance the regulating and controlling ability of the thermal and humidity environment of the greenhouse.

Description

technical field [0001] The invention belongs to the technical field of agricultural facilities and relates to a heat storage and release, dehumidification, ventilation and sterilization type solar greenhouse control system. The system has simple structure, multiple functions and low energy consumption, and can improve the utilization rate of solar energy and improve the thermal environment of the greenhouse control ability. Background technique [0002] The solar greenhouse is a unique anti-season vegetable gardening building in my country. For a long time, the solar greenhouse has basically adopted a passive heat storage structure, mainly relying on the north wall to absorb solar radiation energy for passive heat storage during the day, and the wall at night. The accumulated heat energy is released indoors. Research shows that the solar energy transmitted through the front roof of the greenhouse during the day only affects the heat storage layer of the north wall at a depth...

Problems solved by technology

For example, Chinese patent ZL201410266040.0 proposes a dehumidification method that uses outdoor low-temperature air at night to reduce indoor air humidity and recovers part of the heat; The dehumidification function and ventilation function still need to be completed manually
