Air conditioner and method for controlling same

Abstract

The invention discloses a method for controlling an air conditioner, which comprises the following steps that: A, when a master control circuit of the air conditioner receives a starting instruction, the air conditioner is started to run; B, a stored or received human body area signal and an air guide plate angle signal are called, and also a corresponding temperature coefficient K is called according to the human body area signal and the air guide plate angle signal by the master control circuit of the air conditioner; and C, a temperature T1 of the return air inlet or a temperature T2 of the air outlet of the air conditioner is multiplied by the temperature coefficient K to obtain a supposed temperature T of the area where a human body locates, the supposed temperature T is compared with a set temperature of the air conditioner; in a refrigerating work condition, if the T is greater than T0, operation power or air speed of the air conditioner is increased; and if the T is less than the T0, operation power or air speed of the air conditioner is decreased. The method for controlling the air conditioner disclosed by the invention can control the air conditioner according to the location area of a human body in a room, thus increasing comfort of the human body without adding production cost and processing cost of the air conditioner.

Description

technical field [0001] The invention belongs to the field of air conditioners, and in particular relates to an air conditioner and a control method thereof. Background technique [0002] The existing air conditioner is equipped with a temperature sensor at the return air outlet. During the working process, the main control circuit of the air conditioner needs to compare the air-conditioning temperature set by the user with the temperature at the return air outlet, and then control the temperature of the air conditioner. However, there is a deviation between the temperature of the return air outlet of the air conditioner and the room temperature, especially for the area facing the air outlet of the air conditioner; When the air conditioner is working for a period of time, the body will feel an obvious cold feeling. If the human body is far away from the air outlet of the air conditioner, the human body will still feel relatively hot after reaching the set temperature, which w...

[0002] The existing air conditioner is equipped with a temperature sensor at the return air outlet. During the working process, the main control circuit of the air conditioner needs to compare the air-conditioning temperature set by the user with the temperature at the return air outlet, and then control the temperature of the air conditioner. However, there is a deviation between the temperature of the return air outlet of the air conditioner and the room temperature, especially for the area facing the air outlet of the air conditioner; When the air conditioner works for a period of time, the body will feel the obvious cold feeling. If the human body is far away from the air outlet of the air conditioner, the human body will still feel relatively hot after reaching the set temperature, which will affect the comfort of the human body

Later, some new methods and patents appeared to solve this problem. For example, in Chinese patent 200510103637.4, multiple temperature sensors are set in the room, and each sensor returns the measured temperature to the air conditioner for comparison with the target temperature. Control the operation of the compressor to improve the comfort of the air conditioner, but this method needs to arrange multiple temperature sensors in the room, the price is high, and the operability is not strong for home users
