Air conditioner and control method thereof

Abstract

The invention provides an air conditioner and a control method thereof. The air conditioner comprises a control unit, an air return unit capable of collecting the air return temperature of the air conditioner, a human body induction unit capable of positioning the human body position, and a ground induction unit capable of collecting the non-person area temperature. The control unit comprises a processor and a storage device, a computer program is stored in the storage device, and the program can achieve the following steps when being executed by the processor, wherein the steps include that when the temperature difference between the non-person area temperature collected by the ground induction unit and the air return temperature collected by the air return unit is larger than the presetdifference value, the air conditioner is controlled to conduct refrigerating or heating continuously according to the set mode; or otherwise, the air conditioner is controlled to reduce heating or refrigerating. The control method is based on the above air conditioner. The human body induction unit and the ground induction unit are arranged in the air conditioner, temperature compensation is conducted after the human body ambient temperature is collected and the difference value of the human body ambient temperature and the air return temperature is judged, and therefore indoor comfort is improved effectively.

Description

technical field [0001] The invention belongs to the field of air conditioners, in particular to an air conditioner capable of adjusting return air temperature. Background technique [0002] At present, the control of the outlet air temperature of the air conditioner indoor unit is to adjust the temperature of the outlet air temperature by calculating the difference between the return air temperature and the outlet air temperature. Heavy, resulting in a difference between the return air temperature and the temperature around the human body, thereby reducing the comfort of the human body. For example, when people use the heating function, when the return air temperature of the air conditioner is high, the air conditioner will reduce the frequency of the external unit of the compressor, and the heating capacity will be attenuated. Because the quality of cold and hot air is different, then people under the air conditioner The temperature of the air conditioner is lower than the...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing patent obtains indoor thermal comfort by calculating the difference between the upper and lower collected temperatures. In this way, although partial temperature compensation can be achieved, it is not comprehensive, and because the range of collected temperatures is relatively limited, it cannot be very good. adaptation to the ambient temperature of the human body
