  The technical effect of adopting this method is that the user and the host computer of the air conditioning equipment generally have a certain distance, but the control over the environmental temperature of the air conditioning equipment is controlled based on the environmental temperature detected based on the host computer. . There is a possibility that the environmental temperature of the location where the user is located and the temperature of the location of the host computer may be different. For example, when the air conditioning equipment performs temperature control based on the environment around the host computer, the controlled environmental temperature is Does not meet the requirements of Therefore, since the remote controller is close to the general user, and the temperature around the remote controller and the temperature around the user match or approximate, the remote controller is adopted in the present invention, and the user The ambient temperature can be sensed, and this ambient temperature can be used as the basis for temperature adjustment.

Further, if the angle of the remote controller is not correct, the sensed temperature signal cannot be transmitted to the host computer. Both causes result in technical defects that make it difficult to adjust the ambient conventional temperature to meet the user's requirements.
