Energy-saving heating system for greenhouse

Abstract

The invention discloses an energy-saving heating system for a greenhouse and relates to the technical field of heating for greenhouses. The system comprises the greenhouse, a solar panel and a fan, and a floor heating pipe is laid at the bottoms of planting areas of the greenhouse; a cooling fin is installed between every two adjacent planting areas; the heating pipe and the cooling fins are communicated with a water collection device and a water division device; the solar panel, the fan and a controller are connected, and a solid heat storage electric boiler, a water heat storage electric boiler and an air source heat pump are connected to an inverter; the solid heat storage electric boiler, the water heat storage electric boiler and the air source heat pump are communicated with the water collection device and the water division device. According to the system, through power supply of the solar panel and the fan and combination of solid heat storage, water heat storage and the air source heat pump, heating is conducted for the greenhouse at low temperature, heat supply is achieved through floor heating and the cooling fins, the temperate of air in soil and the greenhouse is evenly increased, the temperature range of hot water can be adjusted, energy is saved, and low-energy-consumption and low-cost planting is achieved.

Description

technical field [0001] The invention belongs to the technical field of greenhouse heating, in particular to an energy-saving heating system for greenhouses. Background technique [0002] In most parts of our country, the winter is severe and long, especially in the north, where the climate is cold in winter and the sunlight is insufficient, so the growth of crops is greatly restricted. In the winter in the north, there is basically no place to grow vegetables except for greenhouses that can be used for planting off-season vegetables. Planting, the low air temperature in winter affects the growth of vegetable stems and leaves. At the same time, the soil temperature is also very low, which affects the normal growth of crops. At present, in view of the low air temperature, people use stoves for heating in greenhouses, but the smoke is inconvenient. Vegetable roots are located in the soil. Among them, the use of stove heating cannot heat the soil, which affects the growth of veg...

Problems solved by technology

[0004] The purpose of the present invention is to provide an energy-saving greenhouse heating system, which uses valley electricity at night for heat storage and water heat storage, and uses photovoltaic and wind power to provide electric energy. , laying floor heating pipes and heat sinks in the greenhouse, and heating through floor heating, solves the problem of high energy consumption in the existing greenhouse, slow heating of the air in the greenhouse, slow and uneven heating of the soil, which may easily cause frozen soil to affect the growth of crops And the problems of high heating cost and poor environmental performance
