Energy-saving hot freon drying and dehumidification system and control method thereof

Abstract

The invention provides an energy-saving hot freon drying and dehumidification system and a control method thereof. The drying and dehumidification system comprises a drying and dehumidification chamber, a hot freon drying and dehumidification unit arranged in the drying and dehumidification chamber, a new air ventilation system and a dehumidification system. The hot freon drying and dehumidification unit, the new air ventilation system and the dehumidification system are in control connection with a control device, and the control device is electrically connected with a temperature sensor located in the drying and dehumidification chamber and a humidity sensor located outside the drying and dehumidification chamber. The control method comprises the steps that the control device is turned on, whether a malfunction occurs or not is detected according to the collected data, and an alarm is given if the malfunction occurs; if all the data are normal, new air ventilation is conducted when the exterior is higher than the interior in temperature and lower than the interior in humidity; and when the interior and the exterior tend to be uniform in humiture, the hot freon drying and dehumidification system is started to conduct drying and dehumidification, and when the exterior is lower the interior in humidity, exhausting and dehumidification are conducted. According to the energy-saving hot freon drying and dehumidification system and the control method thereof, the drying efficiency is improved, and energy consumption and pollution are lowered; and by adoption of intelligent control, convenience and high efficiency are achieved, the cost is saved, control is reliable, and operation is stable.

Description

technical field [0001] The invention relates to drying and dehumidification control technology, in particular to an energy-saving hot fluorine drying and dehumidification system and a control method thereof. Background technique [0002] With the continuous improvement of my country's agricultural production level, residents' living standard and industrial production level, due to the great improvement of my country's agricultural production level, there are many agricultural products such as food, vegetables, and fruits that cannot be consumed in the current season, and need to be dried in time to prevent rot and waste. ; With the continuous improvement of material living standards, many residents hope to eat off-season foods, such as edible fungi, raisins, etc.; in industrial production and manufacturing, especially in precision manufacturing, products need to be dried in time after production to ensure Prevent damage to product nutrition, thereby ensuring product quality. ...

AI Technical Summary

Problems solved by technology

[0003] In the traditional drying process, the commonly used methods are natural drying, gas drying, coal-fired drying, electric drying, etc. Among these drying methods, the natural drying time is too long, the efficiency is low, and it cannot be guaranteed The material is absolutely not rotten, and other drying methods consume a lot of energy and waste resources, and some drying methods also have serious pollution, low intelligence, and cause huge waste of labor, which cannot achieve comprehensive energy-saving effects

In order to overcome the unfavorable factors such as the single application function of the existing ordinary drying and dehumidification equipment, the low efficiency of equipment operation, and environmental pollution
