Dehumidification control system and dehumidification method based on dehumidification temperature

Abstract

The invention discloses a humidity elimination control system based on an elimination starting temperature. The humidity elimination control system comprises a drying chamber, a man-machine interactive module for man-machine interaction, a control module, an execution module, a heat pump unit, a temperature and humidity acquisition module and a humidity elimination air valve. The invention furtherdiscloses a humidity elimination method using the control system. The humidity elimination method comprises the following steps that step 1, drying operation is carried out according to an existing drying process; step 2, the humidity elimination air valve is subjected to air valve starting and stopping cycle operation based on the elimination starting temperature; and step 3, the humidity elimination air valve is subjected to air valve starting and stopping cycle operation based on a humidity target and the elimination starting temperature until the drying operation is completed. According to the humidity elimination control system based on the elimination starting temperature and the humidity elimination method using the control system, it is ensured that humidity elimination operationis effectively carried out on the drying chamber, energy loss caused by too long starting time of the humidity elimination air valve is prevented, the phenomenon that the drying room temperature cannot effectively rise so that the drying process cannot be carried out normally is avoided, the drying temperature can further be basically stabilized, the drying efficiency is improved, and the energy-saving effect is remarkable.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a method for dehumidifying a barbecue system using a heat pump as a heat source. Background technique [0002] Under the general situation of the national environmental protection policy, the baking equipment using the heat pump as the heat source has gradually become the trend of socialized heat source supply. Once the heat pump drying system is installed, the maximum amount of heat it can generate is fixed. [0003] Under harsh working conditions, such as continuous rainy weather and low ambient temperature, it is easy to dehumidify for a long time (before the humidity requirement is not met), thus accelerating the heat loss, but not dehumidifying will affect the material's performance drying quality. [0004] The existing heat pump drying system includes a drying room, a human-computer interaction module for human-computer interaction, a control module, an execution module, a...

AI Technical Summary

Problems solved by technology

Due to the limited air temperature rise, the relative humidity drop is limited, which will cause the relative humidity in the drying room to be unable to drop effectively, so that the dehumidification process cannot be terminated, resulting in a vicious cycle and a great waste of energy, which leads to the failure of the drying process. not working

[0012] At present, there is no dehumidification method that can guarantee the drying process of materials without affecting the drying quality of materials based on time and dehumidification goals
