Active heat storing and heat supplying system of green house

Abstract

The invention discloses an active heat storing and heat supplying system of a green house. The system at least comprises an air source heat pump mainframe, a heat storage buffering water tank, a heatcollecting circulation pump, a heat preserving pipeline, a heat storage and heat supplying disc pipe, an electric adjusting valve, a heat preserving and heat insulation layer, a controller, a temperature sensor and a heat supplying electric adjusting valve. By means of the system, functions of active heat storage, passive heat supplying and active heat supplying can be achieved; the active heat collecting, heating storing and heat supplying of green houses particularly connected glass houses and connected plastic green houses are combined, the heat storing and heat preserving performance of the connected glass houses and the connected plastic green houses can be significantly enhanced to improve the regulating capability of inner air sources on indoor heat environments of the connected glass houses and the connected plastic green houses.

Description

technical field [0001] The invention relates to the technical field of agricultural facilities, in particular to an active heat storage and heat supply system for a greenhouse. Background technique [0002] The temperature in most parts of my country is low in winter, especially in most parts of the north, the outdoor temperature is usually lower than 0°C in winter, but the solar energy resources are abundant, and the temperature inside the greenhouse facilities is higher than 10°C. Moreover, multi-span glass greenhouses and multi-span plastic greenhouses in most parts of my country rely on solar radiation to increase the air temperature in the greenhouse during the day in winter, and rely on boilers and other heating equipment to meet the temperature required for crop growth at night. However, this kind of winter production has the following problems: adopting heating measures needs to consume a large amount of conventional energy, causing environmental pollution and high o...

However, this kind of winter production has the following problems: adopting heating measures needs to consume a large amount of conventional energy, causing environmental pollution and high operating costs

In this way, multi-span glass greenhouses and multi-span plastic greenhouses have limited heat storage capacity during the day, and only rely on the topsoil layer to passively supply heat to the room, resulting in a low function of the heat storage soil layer to regulate the thermal environment of the greenhouse.

Heating measures are required at night, consuming a large amount of conventional energy, causing environmental pollution and high operating costs
