Determining device and method for air conditioner operation frequency and air conditioner

Abstract

The invention provides a determining device and method for air conditioner operation frequency and an air conditioner. The determining device comprises a triggering unit, a temperature change speed determining unit and a frequency determining unit, wherein the triggering unit is used for triggering the temperature change speed determining unit when the indoor temperature is adjusted to the set temperature and is close to the preset value range of the set temperature; the temperature change speed determining unit is used for determining the temperature change speed of the indoor temperature under a preset frequency; and the frequency determining unit is used for determining the target frequency of the air conditioner according to the temperature change speed determined by the temperature change speed determining unit. According to the scheme, by determining the operation frequency of the air conditioner, the frequency change can better satisfy the load of a room, excessive dehumidification caused by constant high-frequency operation of the air conditioner is reduced, and energy consumption caused by machine halt when the room temperature is decreased to the temperature point can be also reduced. Energy is saved, and a user feels more comfortable.

Description

technical field [0001] The invention relates to the field of electric appliance control, in particular to an air conditioner operating frequency determination device and method and an air conditioner. Background technique [0002] In order to achieve the effect of rapid cooling, inverter air conditioners generally increase the cooling capacity by continuously increasing the operating frequency of the air conditioner, which inevitably reduces the evaporation temperature of the air conditioner, resulting in a large amount of dehumidification of the room air by the indoor unit when processing the room air , increasing the latent heat energy consumption of the air conditioner. And after the room drops to the set temperature, due to the slow frequency adjustment, the room temperature often overshoots, that is, the air conditioner stops at the temperature point, which not only affects the comfort of the human body, but also increases energy consumption. [0003] In the prior art,...
