Radiant air conditioner indoor unit, air conditioning system and control method

Abstract

The invention provides a radiant air conditioner indoor unit, an air conditioning system and a control method. The radiant air conditioner indoor unit comprises a radiant panel and a microchannel heatexchanger. The radiant panel is attached to the side face, facing indoors, of the microchannel heat exchanger. According to the radiant air conditioner indoor unit, the air conditioning system and the control method provided by the invention, by arranging the microchannel heat exchanger and the radiant panel, radiant heat exchange and natural convection heat exchange can be achieved, the user comfort is improved, in addition, by arranging the radiant panel, the radiation efficiency and comfort can be improved, the appearance of the microchannel heat exchanger is beautified, the mounting and later maintaining difficulty is lowered, due to the fact that a coolant is directly introduced into a room, the temperature range for heat exchange is enlarged, by arranging a thermal infrared imager and an image collecting device, the frequency of a compressor and/or the opening degree of an adjusting valve can be intelligently adjusted according to the detected indoor temperature, body temperature of a user and physical state of the user, the purpose of intelligent control is achieved, and by arranging a second heat exchanger, the radiant heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to a radiant air-conditioning indoor unit, an air-conditioning system and a control method. Background technique [0002] Traditional air-conditioning systems use convection to exchange heat. The typical problem is strong blowing sensation and uneven air distribution in the room. In order to solve the problem of strong blowing sensation, radiation heat exchange can be used, but in the prior art , the commonly used radiation medium is hot and cold water, and the heat exchange method is secondary heat exchange, which not only increases the energy consumption of the system, but also increases the installation cost, and the heat exchange efficiency of the room is low. Contents of the invention [0003] In order to solve the above technical problems, a radiant air-conditioning indoor unit, an air-conditioning system and a control method are provided that directly use...
