Indoor unit air gear adjusting method and device and air conditioner indoor unit

Abstract

The invention discloses an indoor unit air gear adjusting method. The method includes the steps that the values of a first operation parameter and a second operation parameter of an indoor unit are obtained regularly with a first preset period as the interval and stored; the difference values of the first operation parameter and the second operation parameter in the corresponding period are regularly calculated with a second preset period as the interval; and when the difference values are larger than a first preset threshold value, the value of a first variable is used as an air gear level difference value to increase the air gear, or when the difference values are smaller than a second preset threshold value, the value of the first variable is used as an air gear level difference value to decrease the air gear. The invention further discloses an indoor unit air gear adjusting device and an air conditioner indoor unit. By the adoption of the indoor unit air gear adjusting method and device and the air conditioner indoor unit, the air gear of the indoor unit is automatically adjusted to be increased or decreased correspondingly according to the different conditions of the relationship between the difference values of the two preset operation parameters of the indoor unit and the preset threshold values, the situation that the output of an indoor fan is excessive when the values of the two operation parameters are greatly different due to the fact that the air gear is fixed is avoided, and the energy saving purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an indoor unit windshield adjustment method and device, and an air conditioner indoor unit. Background technique [0002] In the 21st century where energy is increasingly scarce and resources are increasingly depleted, energy conservation is not only a beneficial solution to the energy crisis, but also a challenge to human beings to maintain sustainable development. In the environment of global warming and frequent extreme climates, heat pump air-conditioning systems, which are large energy consumers, urgently need to make a difference in energy saving. It is undeniable that since outdoor units consume most of the electric energy, there are currently many solutions for energy saving of outdoor units. However, indoor units with relatively low energy consumption are often ignored in terms of energy saving. In order to ensure the continuous cooling or heating of the indoor...
