Mixed-flow air conditioner and mixed-flow control method thereof

Abstract

The invention relates to a mixed-flow air conditioner and a mixed-flow control method of the mixed-flow air conditioner. The mixed-flow control method of the mixed-flow air conditioner includes the special steps that a temperature setting signal is received; a predetermined region in front of air outlets is induced, and a human body induction signal is generated; and whether a human body exists in the predetermined region or not is judged according to the human body induction signal, if not, a controllable damper is closed to interrupt a through path, and if yes, the distance between the human body and the air outlets is induced, the controllable damper is controlled to connect the through path by the preset opening according to the distance, and air passes a heat exchange gap between the through path and a heat exchange device according to the predetermined ratio, then flows in to a flow mixing space to be subjected to flow mixing and then is sent out to an environmental space through the air outlets. The invention further provides the mixed-flow air conditioner. The mixed-flow air conditioner comprises the heat exchange device, the through path, the controllable damper, an induction device, a distance measurement device, a control device and a drive device, and the output air temperature of the mixed-flow air conditioner can be controlled automatically.

Description

technical field [0001] The invention relates to air conditioning technology, in particular to a mixed-flow air conditioner and a mixed-flow control method thereof. Background technique [0002] The air duct structure of a common air conditioner in the existing market is generally composed of an air inlet, a centrifugal fan, an evaporator and an air outlet. Indoor air enters the interior of the air conditioner from the air inlet, and after being centrifugally accelerated by the centrifugal fan, the air passes through the evaporator for heat exchange, and the air after heat exchange is blown into the room through the air outlet. However, the temperature of the cool air blown out from the air outlet is too low and not soft enough, and it will cause discomfort to the user when blown on the body. [0003] In order to solve the above technical problems, a drainage air conditioner has appeared in the prior art, which introduces a little indoor air at the air outlet of the air cond...

AI Technical Summary

Problems solved by technology

However, this drainage air conditioner cannot automatically control the temperature of its output air according to the actual situation (such as whether there is a human body in the room, the distance between the human body and the air outlet of the air conditioner, etc.), which is inconvenient to use; The air duct structure and air outlets were completely remodeled, resulting in an oversized air conditioner and an increase in cost
