In-shed dehumidification device and method based on liquid internal circulation and indoor temperature difference

Abstract

The invention relates to the technical field of indoor dehumidification, and discloses an in-shed dehumidification device and method based on liquid internal circulation and indoor temperature difference, the in-shed dehumidification device comprises an indoor dehumidification host and an outdoor unit, the indoor dehumidification host is internally provided with a gas heat exchange pipe used for cold liquefaction of indoor air and an exhaust fan communicated with the gas heat exchange pipe; a thin-wall metal pipe communicated with the output end of the cooling liquid circulating pump is installed in the gas heat exchange pipe, a plurality of sets of basin-shaped airflow guide covers and basin-shaped backflow guide covers which are used for changing airflow circulation paths are further arranged in the gas heat exchange pipe, and a vibration assembly capable of driving the thin-wall metal pipe to vibrate is further arranged in the gas heat exchange pipe. The surrounding type detention liquefaction dehumidification effect on indoor air is achieved, meanwhile, the influence of liquefied water drops on air liquefaction is reduced, the heat conversion rate of the gas heat exchange pipe is increased, and the adverse effect on animals and plants caused by too high humidity in the greenhouse is avoided.

Description

technical field [0001] The invention relates to the technical field of indoor dehumidification, in particular to a dehumidification device and method in a shed based on liquid internal circulation and indoor temperature difference. Background technique [0002] The greenhouse is a high-humidity environment. The relative humidity of the air in the greenhouse can generally reach 50% to 60% during the day, and it is often around 90% or even 100% at night. In the horizontal distribution of relative humidity, the peripheral part is 10% higher than the central part. Ventilation and irrigation have a great influence on the relative humidity of the air in the shed, the former dehumidifies and the latter humidifies. Especially in winter, when the humidity in the shed is too high, it will induce and aggravate the occurrence of diseases and insect pests, and it is easy to cause diseases such as plant flower drop and fruit drop, seedling rot, etc. It will also increase the probability ...
