Dehumidification control method of air conditioner and air conditioner

Abstract

The invention discloses a dehumidification control method of an air conditioner. The method comprises the following steps of controlling the air conditioner to enter a dehumidification mode, and detecting the indoor environment temperature; determining a current relative humidity parameter; searching for a dew point temperature corresponding to the current relative humidity at the indoor environment temperature according to the relationship among a preset relative humidity parameter, the indoor environment temperature and dew point temperature, and determining a dew point temperature range corresponding to the current dehumidification mode according to the dew point temperature; and controlling the temperature of an indoor coil pipe within the dew point temperature range according to the adjusted operating parameters until the operating mode of the air conditioner is switched or the air conditioner is switched off. The embodiment of the invention further discloses the air conditioner.The purpose of dehumidification without cooling is realized by increasing no hardware. Meanwhile, due to the fact that a plurality of different dehumidification modes are set, dehumidification comfortrequirements of different environments are met.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner dehumidification control method and the air conditioner. Background technique [0002] With the maturity of consumption concepts of domestic consumers, comfort is a development direction of air conditioners in the future. When the room temperature is 16-25 degrees Celsius, the room is relatively humid, and the indoor temperature does not need to be refrigerated, but it is required to reduce the humidity. [0003] At present, the dehumidification mode adopted by most air conditioners is the freezing dehumidification mode with outdoor throttling. This dehumidification mode has the disadvantage that the indoor temperature drops during dehumidification, which affects the comfort of customers. [0004] Some manufacturers have used humidity sensors and indoor throttling refrigeration dehumidification technology on inverter air conditioners to reduce the ind...

Problems solved by technology

However, this method needs to increase the humidity sensor, which will increase the cost

At the same time, both have a single dehumidification mode, which cannot meet the comfort requirements of dehumidification in a variety of different use environments.
