Heat pump drying room dehumidification control system based on time and target, and dehumidification method

Abstract

The invention discloses a heat pump drying room dehumidification control system based on time and a target. The system comprises a drying room, a human-computer interaction module used for human-computer interaction, a control module, an execution module, a heat pump unit, a temperature and humidity acquisition module and a dehumidification air valve. The control module is provided with a parameter storage inside. The invention further discloses a dehumidification method. The dehumidification method comprises the steps of firstly, carrying out drying operation according to an existing technology; secondly, carrying out air valve opening and closing cycle operation based on time on the dehumidification air valve; and thirdly, carrying out air valve opening and closing cycle operation basedon the humidity target and time on the dehumidification air valve till drying operation is finished. With the heat pump drying room dehumidification control system based on time and the target, and the dehumidification method, it can be guaranteed that effective dehumidification operation is carried out on the drying room, energy loss caused by the situation that the dehumidification air valve isopened for too long is avoided as well, it is avoided that a drying technology cannot be normally carried out because the temperature in the drying room cannot rise effectively, the purposes of energysaving and benefit increase are achieved, and the purpose of guaranteeing effective operation of the drying technology is achieved.

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
