Circulating air temperature control greenhouse system and temperature control method thereof

Abstract

The invention discloses a circulating air temperature control greenhouse system which comprises a main greenhouse, a temperature adjusting chamber, an air return chamber, a wet curtain, an air conditioner coil pipe and a circulating pipeline, a support for placing potted plants is arranged in the main greenhouse, the temperature adjusting chamber is arranged below the outer side of a long side wall body of the main greenhouse, and the air return chamber is arranged in the temperature adjusting chamber; the circulating pipeline comprises a plurality of groups of circulating units arranged in parallel, each circulating unit comprises an air outlet pipe, a return air inlet pipe and a return air pipe, each air outlet pipe is arranged at the top of the main greenhouse, an air inducing fan and a plurality of air distribution holes for exhausting air re arranged in each air outlet pipe, and the root of each air outlet pipe communicates to the temperature adjusting chamber through a vertical air inducing pipe; and each air return inlet pipe is arranged in the main greenhouse and away from one end of the temperature adjusting chamber, the root of each air return inlet pipe communicates to the air return chamber through the air return pipe laid underground, and the wet curtain and the air conditioner coil pipe are arranged on an air outlet of the air return chamber. According to the circulating air temperature control greenhouse system and the temperature control method thereof, through the arrangement of the circulating pipeline, uniform flowing circulation of air in the greenhouse can be improved, and the controllability of the temperature in the greenhouse is good.

Description

technical field [0001] The invention relates to the technical field of flower greenhouse temperature control, in particular to a circulating air temperature control greenhouse system and a temperature control method thereof. Background technique [0002] Now in horticultural production, the greenhouse has become a necessary basic facility for flower cultivation. The production process of greenhouse flower cultivation is basically carried out in an artificially controlled environment, and is less affected by changes in natural conditions, especially external meteorological conditions. That is, it can maintain a good microclimate inside the greenhouse and create the most suitable environmental conditions for flower growth. [0003] In the existing orchid cultivation greenhouses, the temperature control management is relatively extensive. When the temperature is low, multiple built-in radiators are often used to heat and increase the temperature. When the temperature is high, ...

AI Technical Summary

Problems solved by technology

[0003] In the existing orchid cultivation greenhouses, the temperature control management is relatively extensive. When the temperature is low, multiple built-in radiators are often used to heat and increase the temperature. When the temperature is high, most of them are cooled by fans and wet curtains.

This temperature adjustment method often has hysteresis, the air flow rate in the greenhouse is slow, and the temperature distribution is uneven, which affects the normal growth of orchid seedling cultivation.
