Air conditioning system and dehumidification control method and device thereof

Abstract

The invention discloses an air conditioning system and a dehumidification control method and device thereof. The air conditioning system comprises an indoor unit and an outdoor unit. The indoor unit comprises an electric auxiliary heater and an indoor fan. The method comprises the following steps that whether the air conditioning system meets the dehumidification condition or not is judged; if the air conditioning system meets the dehumidification condition, the air conditioning system is controlled to be in refrigeration operation, the current indoor environment temperature is acquired, and whether the current indoor environment temperature is smaller than first preset temperature or not is judged; and if the current indoor environment temperature is smaller than the first preset temperature, the electric auxiliary heater is controlled to be in a starting state so as to balance temperature reducing during refrigeration operation of the air conditioning system. Therefore, it is guaranteed that in the dehumidification process, the room temperature is reduced slowly or the temperature is not reduced, the requirements of a user for the temperature and humidity are met, and meanwhile the aim of energy saving is achieved; and the structure is simple, and cost is low.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a dehumidification control method for an air conditioning system, a dehumidification control device for the air conditioning system, and an air conditioning system with the dehumidification control device. Background technique [0002] With the improvement of people's living standards, the quality requirements for the living environment are also getting higher and higher. Not only the indoor temperature is required to meet the user's comfort needs, but also the indoor humidity is required to meet the user's comfort needs. [0003] In order to meet the user's requirements for temperature and humidity at the same time, the current constant temperature dehumidification air conditioner divides the indoor heat exchanger into two parts, one part of the indoor heat exchanger is used for cooling and dehumidification, and the other part of the indoor heat exchanger acts as a conde...

[0003] In order to meet the user's requirements for temperature and humidity at the same time, the current constant temperature dehumidification air conditioner divides the indoor heat exchanger into two parts, one part of the indoor heat exchanger is used for cooling and dehumidification, and the other part of the indoor heat exchanger acts as a condenser for heating. Although it has a certain effect, the system is complicated and the cost is high
