Description

Air conditioner and control method thereof
Technical Field
The invention relates to the technical field of air conditioners, and particularly provides an air conditioner and a control method thereof.
Background
With the continuous improvement of the living standard of people, the air conditioner becomes a necessary living electric appliance in the families of consumers. Generally, in the using process of an air conditioner, after a user inputs a set temperature through a remote controller, the air conditioner determines an operation power according to the set temperature and operates according to the determined operation power, simultaneously detects an indoor temperature in real time and compares the indoor temperature with the set temperature, and controls the air conditioner to operate or temporarily stop operating according to a comparison result.
However, in the using process, after the user turns on the air conditioner and inputs the set temperature, the user does not adjust the set temperature for a long time or even does not adjust the set temperature any more in many cases. For example, in the morning of winter, the outdoor environment temperature is low, the indoor temperature is also low, in order to enable the indoor temperature to rise rapidly, a user inputs a high set temperature after turning on the air conditioner, and when the user arrives at noon, the outdoor environment temperature rises and the speed of the indoor heat loss to the outdoor is reduced. The air conditioner is still operated at the initial set temperature, causing energy waste, and the indoor temperature is not in a temperature range in which the human body is comfortable but in a relatively high temperature range, and the user can recognize to readjust the set temperature only when the user strongly feels discomfort. Similarly, in hot summer, the outdoor ambient temperature is higher in the afternoon, resulting in a relatively high indoor temperature, and in order to rapidly lower the indoor temperature, the user inputs a lower set temperature after turning on the air conditioner, and when it is evening, the outdoor temperature is lowered, and the speed of the outdoor heat entering the room is small. The air conditioner is still operated at the initial set temperature, which causes energy waste, and the indoor temperature is not in a temperature range where the human body is comfortable, but in a relatively low temperature range.
Therefore, there is a need in the art for a new solution to the above problems.
