Vegetable planting greenhouse with controllable temperature adjustment function

Abstract

The invention discloses a vegetable planting greenhouse with a controllable temperature adjustment function. The vegetable planting greenhouse comprises a greenhouse body placed on the ground, whereinthe greenhouse body comprises a top and side walls; a cooling and heat storage water flow loop and a heat preservation and heat dissipation water flow loop are arranged in the top and the side wallsof the greenhouse body; the cooling and heat storage water flow loop and the heat preservation and heat dissipation water flow loop are connected with the same water storage tank; a plurality of connecting plates are arranged on the bottom of the greenhouse body; the connecting plates are connected with the ground through expansion screws; and a temperature adjustment system is arranged on the side walls of the greenhouse body. According to the vegetable planting greenhouse, the meshing condition of a first rack and a second rack with a rotating gear is controlled by adopting different boilingpoints of methyl formate and acetaldehyde in a methyl formate storage tank and an acetaldehyde storage tank, so that a communication effect of a water flow reversing device with a first water inlet and a first water outlet and a communication effect of the water flow reversing device with a second water inlet and a second water outlet can be controlled, and switching between the cooling and heatstorage water flow loop and the heat preservation and heat dissipation water flow loop is completed.

Description

technical field [0001] The invention relates to the technical field of temperature control and temperature regulation, in particular to a vegetable planting greenhouse with controllable temperature regulation. Background technique [0002] At present, in the heat preservation and cooling adjustment device of the vegetable greenhouse, a large number of energy-consuming equipment are often used to adjust the temperature in the vegetable greenhouse. These equipment often occupy a large amount of space inside the vegetable greenhouse, which reduces the available space in the vegetable greenhouse. At the same time, in the process of temperature control, it is necessary to use temperature sensors with high sensitivity to monitor and adjust the temperature in the vegetable planting greenhouse, which often requires regular inspection and maintenance of these instruments and equipment, which often increases the workload. . [0003] For this reason, we have designed a vegetable growi...
