Problems solved by technology

[0002] The air outlets of existing air conditioners are all on the upper side of the fuselage. When the air conditioner is cooling and heating, the air can only be blown out from the upper side of the fuselage. When it is hot, after the wind blows out from the upper side of the fuselage, because the hot air is lighter than the cold air, it will cause the hot air to run upwards and the cold air to sink, resulting in a large temperature difference between the upper and lower sides of the room during heating, giving users a sense of Feeling of hot head and cold feet, poor user experience

Embodiment 1

[0044] Please also refer to Figure 1 to Figure 4 and Figure 8, the air conditioner indoor unit 1 provided by Embodiment 1 of the present invention will now be described. This air-conditioning indoor unit 1 includes a housing 11, an indoor main radiator and a main cross-flow fan 131, wherein at least one main cross-flow fan 131 can be provided, and two or more can also be provided according to actual needs. The illustration in this embodiment Among them, two main cross-flow fans 131 are provided; more importantly, this kind of air-conditioning indoor unit 1 is provided with indoor auxiliary radiators and auxiliary cross-flow fans 132; The cavity 111 and the lower cavity 112 located at its lower part, the upper part of the casing 11 is provided with the same number as the number of the main cross-flow fans 131, and the upper side air outlets 1110 communicated with the upper cavity 111, this embodiment In the illustration, corresponding to the number of main cross-flow fans 1...

Embodiment 2

[0048] See Figure 1 to Figure 4 , Figure 9 and Figure 10 The difference between the present embodiment and the first embodiment is that the air-conditioning indoor unit 1 further includes a bypass valve tube assembly for bypassing the indoor auxiliary heat exchanger 122 from the refrigerant circulation loop of the air-conditioning system. Specifically, in this embodiment, the valve pipe assembly includes a first sub-pipe for refrigerant 101, a second sub-pipe for refrigerant 102, a first electric control valve 31 provided on the first sub-pipe for refrigerant 101, and a first electric control valve 31 provided on the second sub-pipe for refrigerant. The second electric control valve 32 on the road 102, wherein, in order to facilitate the automatic control of the controller, the first electric control valve 31 and the second electric control valve 32 are preferably solenoid valves, of course, they can also be other valves with refrigerant on and off. Electric control valve...

Embodiment 3

[0054] Please send Figure 11 and Figure 9 or Figure 10 For comparison, the difference between the present embodiment and the second embodiment is that the other end of the first refrigerant sub-pipeline 101 and the other end of the second refrigerant sub-pipeline 102 are merged to be connected to the liquid side interface of the outdoor unit instead of the gas side. The interface connection, other structures and principles are the same as those in Embodiment 2, and will not be repeated here.

Abstract

The invention provides an air conditioner, an indoor unit thereof and a method for controlling the air conditioner. The indoor unit of the air conditioner at least comprises two indoor heat exchangers; one of the indoor heat exchangers is a main indoor heat exchanger and is arranged on the upper side of a body of the air conditioner; the other indoor heat exchangers are auxiliary indoor heat exchangers and are arranged on the lower side of the body of the air conditioner. The air conditioner, the indoor unit thereof and the method have the advantages that the air conditioner is reasonable in structural arrangement, the main indoor heat exchanger, main cross-flow fans, the auxiliary indoor heat exchangers and auxiliary cross-flow fans run simultaneously in a heating procedure, the heating comfortableness of the room air conditioner is enhanced by means of reasonably utilizing an air circulating system, accordingly, a heating effect can be effectively improved, the temperature difference between upper air and lower air in a room is reduced, and the problem of poor comfortableness of an existing room air conditioner is effectively solved; the air conditioner and the indoor unit thereof are simple in structure and principle, can be controlled conveniently and practically and are easy to implement.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and more specifically relates to an air conditioning indoor unit capable of effectively reducing the temperature difference between upper and lower air in an air conditioning room, an air conditioner using the air conditioning indoor unit, and a control method for the air conditioner. Background technique [0002] The air outlets of existing air conditioners are all on the upper side of the fuselage. When the air conditioner is cooling and heating, the air can only be blown out from the upper side of the fuselage. When it is hot, after the wind blows out from the upper side of the fuselage, because the hot air is lighter than the cold air, it will cause the hot air to run upwards and the cold air to sink, resulting in a large temperature difference between the upper and lower sides of the room during heating, giving users a sense of The feeling of hot head and cold feet, the user experie...
