Problems solved by technology

However, when an on-off auxiliary heat source is used, the ambient heat load will show a jumping change, and the input or withdrawal of the auxiliary heat source will correspondingly cause the heat of the unit to be greater than or less than the actual adjustment demand, breaking the original equilibrium state, resulting in Ambient temperature and humidity fluctuations
In order to achieve the new control point of temperature and humidity accuracy, a certain adjustment cycle is required for new frequency modulation control, so it cannot meet the requirements of long-term constant temperature and humidity or the effect of high temperature and humidity control accuracy

Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0019] Such as figure 1 As shown, this embodiment provides a constant temperature dehumidification control method for an inverter air conditioner. The inverter air conditioner suitable for this method includes an auxiliary heating device with adjustable heat supply. The above method specifically includes the following steps: In the dehumidification mode, the When the heat supply of the auxiliary heating device is adjusted, the operating frequency of the compressor is correspondingly increased or decreased synchronously.

[0020] The corresponding synchronous increase or decrease of the operating frequency of the compressor mentioned above means that when the heat supply of the auxiliary heating device is increased, the operating frequency of the compressor is correspondingly increased, and when the ...

Abstract

The invention relates to the technical field of air-conditioner equipment, in particular to a constant temperature and dehumidification control method for a variable frequency air conditioner. The variable frequency air conditioner applicable to the method comprises an auxiliary heating device with the adjustable heat supply capacity. The constant temperature and dehumidification control method for the variable frequency air conditioner comprises the step that the working frequency of a compressor is synchronously increased or decreased correspondingly when the heat supply capacity of the auxiliary heating device is adjusted in the dehumidification mode. When the heat supply capacity of the auxiliary heating device of the air conditioner changes, the running frequency of the compressor is decreased or increased synchronously so as to offset load fluctuations caused by changes of the heat supply capacity of the auxiliary heating device, large temperature fluctuations caused by the changes of the heat supply capacity of the auxiliary heating device are prevented, and the purposes of constant temperature and dehumidification are achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for controlling constant temperature and dehumidification of frequency conversion air conditioners. Background technique [0002] The operating environment of variable frequency precision air conditioners has high requirements for temperature and humidity accuracy. When it is in an environment with low heat load and high humidity load, due to the low heat load, in order to ensure the temperature accuracy requirements, the output capacity of the unit is required to be low, so the compressor is required to be in a low-frequency operation state. But at the same time, due to the high humidity load, in order to meet the humidity accuracy requirements, the unit is required to output a large capacity to meet the dehumidification requirements. Due to the large difference between heat load and humidity load on unit capacity requirements, in order to solve this problem, p...
