Dehumidifying control method, device and equipment with dehumidifying function

Abstract

The invention provides a dehumidifying control method, device and equipment with a dehumidifying function. The dehumidifying control method comprises the steps of the detecting step, the calculating step and the control step. The detecting step is used for detecting the indoor relative humidity and the indoor environment temperature. The calculating step is used for calculating the humidity difference and the temperature difference. The humidity difference is the difference value of the detected indoor relative humidity with the optimal comfort humidity, and the temperature difference is the difference value of the detected indoor environment temperature and the set comfort temperature value. The control step is used for controlling gears of an inner fan and the pipe temperature in an evaporator of the dehumidifying equipment according to the calculating result of the humidity difference and the temperature difference. According to the technical scheme, precision controlling over the comfort environment and the dehumidifying amount is achieved; the dehumidifying speed is high; the situations that indoor humidity decreasing is too large or too small and energy saving is not achieved at the time of dehumidifying are improved; practicability is strong; and good user experience is achieved.

Description

technical field [0001] The invention relates to the technical field of dehumidification, in particular to a dehumidification control method, device and equipment with dehumidification function. Background technique [0002] With the development of society, people's living standards have been generally improved, and equipment with dehumidification function has become a must-have in people's daily life. However, most of the current dehumidification models of ordinary air conditioners do not have a humidity sensor, and the internal fan has a fixed and low speed. The frequency of the compressor is controlled according to the temperature difference between the indoor temperature and the set value and the room temperature change rate. The control principle is that when the ambient temperature is detected to be higher than the set temperature value, the internal fan speed is fixed, and the compressor frequency will increase to a certain value to lower the internal tube temperature ...

Problems solved by technology

This kind of control logic indirectly feeds back the humidity level through the change speed of the dry bulb temperature. It can only make a rough judgment, and cannot accurately quantify the relative humidity to ensure a comfortable environment, and there will be phenomena such as too low dehumidification and too large a temperature drop. wasted cooling

The dehumidification scheme of the existing technology is difficult to meet the needs of users in terms of dehumidification accuracy and comfort
