Local constant temperature system for air energy agricultural greenhouse

Abstract

The invention discloses a local constant temperature system for an air energy agricultural greenhouse. The local constant temperature system comprises an air energy host, a constant temperature watertank, a heating water pump, a main heating pipe, a main water return pipe, a microcomputer and a seed bed, wherein the main heating pipe and the main water return pipe are positioned at one end of theconstant temperature water tank; the main heating pipe, the main water return pipe and the constant temperature water tank form a plant heating circuit; two groups of water ducts are connected between the air energy host and the constant temperature water tank; and the air energy host, the constant temperature water tank and the water pipe form a water heating circuit. According to the local constant temperature system for the air energy agricultural greenhouse disclosed by the invention, by virtue of local heating, only plants are heated, and the whole greenhouse does not need to be heated,so that the purposes of saving energy and protecting environment are achieved; and the air energy is controlled by the microcomputer, and any manual operation is avoided, so that the manual cost is greatly saved, and zero pollution is realized. Finally, the pipeline can be removed for next planting after planting of annual plants is ended, so that the cost is reduced, and excellent application prospects are brought.

Description

technical field [0001] The invention relates to the field of agricultural greenhouses, in particular to an air energy local constant temperature system for agricultural greenhouses. Background technique [0002] The temperature distribution in nature changes with time and space. In time, the temperature changes periodically with the four seasons and the alternation of day and night. In space, the temperature decreases with the increase of latitude and altitude. These changes in temperature have different effects on various aspects of plant growth and development. [0003] According to the principles of botany, all biochemical actions of plants in the whole life cycle must be carried out under certain ambient temperature conditions. When other factors required by plant life are basically satisfied, within a certain temperature range, the ambient temperature is positively correlated with plant growth and development. Generally, each plant corresponds to a minimum growth tempe...
