Temperature regulation system and regulation method for greenhouse

Abstract

The invention discloses a temperature regulation system and regulation method for a greenhouse. The temperature regulation system comprises a temperature control unit, a water circulation device, a heat exchanger, a storage device, an evaporator, a condenser and a compressor, wherein the water circulation device is respectively connected with the evaporator and the compressor; the condenser is connected with the compressor; the water circulation device comprises a water storage tank, a water pump and a water circulation pipeline; the water pump is connected with the condenser and the evaporator through the water circulation pipeline; and the water circulation pipeline is provided with a reversing valve. The regulation method is characterized in that a phase-change material or water in a liquid storage bottle is subjected to heating vaporization by means of the evaporator and stored in a gas storage bottle; and the phase-change material in the gas storage bottle is compressed to the condenser by means of the compressor, subjected to heat radiation cooling and stored in the liquid storage bottle. The temperature regulation system disclosed by the invention can realize automated control of refrigeration and heating cycles and realize automatic storage and circulation of energy, is efficient and environmentally friendly, and greatly lowers the temperature regulation cost of the greenhouse.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a temperature control system for a greenhouse and a control method thereof. Background technique [0002] Greenhouse refers to the control of temperature, humidity, light, soil moisture, nutrients and CO in a designated area through manual intervention. 2 Concentration and many other environmental factors are comprehensively regulated to make it suitable for the growth needs of the cultivated crops. Because it gets rid of the influence and limitation of location, season and external climate, it can effectively improve agricultural ecology and production conditions, and promote the scientific research of agricultural resources. Development and rational use to improve land productivity, labor productivity and social and economic benefits. Therefore, it has been widely used in the world. [0003] At present, the most popular greenhouses in China are passive greenhouses...

Problems solved by technology

Traditional temperature control methods such as: air conditioners, kangs, coal-fired boilers, electric heating wires, etc., mostly have disadvantages such as high cost and potential danger, and cannot be heated or cooled in advance to meet the temperature control requirements of the greenhouse, and energy consumption cannot be reduced. Low and cheap energy Heating or cooling in advance for use when energy consumption peaks
