Air-conditioning system, air-conditioner and control method thereof

Abstract

The invention discloses an air-conditioning system. The air-conditioning system comprises an outdoor side and an indoor side, wherein two or more indoor units are arranged in the indoor side; radiation heat exchangers are arranged on at least one indoor unit; the invention further discloses an air-conditioner including the above air-conditioning system, and a control method for the air-conditioner; the above air-conditioning system is arranged in the air-conditioner; in the air-conditioning system, the radiation heat exchanger is arranged on one indoor unit or an ordinary heat exchanger is arranged on the other indoor unit; the radiation heat exchangers can be arranged on one or more indoor units; compared with the prior art that an radiation plate and the heat exchanger are arranged on the same air-conditioner, the separately controlled radiation heat exchangers and ordinary heat exchanger are diversified in control manners; according to the condition of indoor environment temperatures, the combined control of the radiation heat exchangers and the ordinary heat exchanger under different work conditions is realized and energy conservation effect is improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to an air conditioning system, an air conditioner and a control method thereof. Background technique [0002] Traditional air conditioners, when heating, use ordinary indoor heat exchangers for heating. The temperature of the air outlet is too high, and it is easy to feel hot when the hot air blows to the human body; there are also existing radiant panels and ordinary heat exchangers. Combined indoor units, but these are all installed on the same air conditioner, although to a certain extent, the heat generated by the hot air blowing to the human body can be alleviated through the heating of the radiant panel, but this kind of control has great limitations, and there is no It is very good to control the working conditions of the radiant plate and the ordinary heat exchanger according to the room temperature, but the energy-saving effect is poor; in addition, the rad...

[0002] Traditional air conditioners, when heating, use ordinary indoor heat exchangers for heating. The temperature of the air outlet is too high, and it is easy to feel hot when the hot air blows to the human body; there are also existing radiant panels and ordinary heat exchangers. Combined indoor units, but these are all installed on the same air conditioner, although to a certain extent, the heat generated by the hot air blowing to the human body can be alleviated through the heating of the radiant panel, but this kind of control has great limitations, and there is no It is very good to control the working conditions of the radiant plate and the ordinary heat exchanger according to the room temperature, but the energy-saving effect is poor; in addition, the radiant plate and the ordinary heat The air density is small, causing the heat to be concentrated on the upper part, and the temperature of the human foot is low, which will lead to poor comfort and cannot meet people's requirements for comfort
