Problems solved by technology

[0004] Because the indoor fan of the air conditioner unit stops running during the defrosting process, it stops heating the room, causing the room temperature to drop and affecting the comfort of the room
The air conditioning unit cannot heat the room during the process of preventing cold wind, which will further reduce the room temperature, further affect the comfort of the room, and affect the user experience
[0005] Under the cooling condition, the return air with high indoor temperature enters the shell of the indoor unit of the air conditioner from the return air outlet, and exchanges heat with the refrigerant in the indoor heat exchanger as an evaporator to cool down, and then blows out through the air outlet. The temperature of the cold air blown out is relatively low, which is likely to cause discomfort to the user, and long-term direct blowing may even cause the user to catch a cold and have a headache
[0006] In addition, although the air-conditioning unit in the prior art can dehumidify by working under refrigeration conditions, because its evaporation temperature is higher than that of a dedicated dehumidifier, the dehumidification capacity of the air-conditioning unit is weak, and it needs to consume more energy to remove the same water. High power consumption; if the evaporating temperature is forcibly lowered, the outlet air temperature will be very low. During the dehumidification process, the air outlet will blow cold air, causing discomfort to the user. Therefore, it is difficult to dehumidify under cooling conditions when the ambient temperature is low

no. 1 example

[0049] Figure 1 to Figure 3 The principle and structure of the air-conditioning unit and its air-conditioning indoor unit according to the first embodiment of the present invention are shown.

[0050] like figure 1 As shown, in this embodiment, the air conditioner indoor unit 1 mainly includes a casing 11 , an indoor heat exchanger 12 , an indoor fan 13 and a heat storage structure 14 . The indoor heat exchanger 12 , the indoor fan 13 and the heat storage structure 14 are arranged in the casing 11 .

[0051] The casing 11 is provided with a first air return port 111 , a second air return port 112 and an air outlet 113 . Both the first air return port 111 and the second air return port 112 can be opened and closed. In this embodiment, the first air return port 111 is located at the front upper part of the casing 11 . The second air return port 112 is located at the rear upper part of the casing 11 . The air outlet 113 is located at the lower front side of the casing 11 . ...

no. 2 example

[0074] Figure 4 and Figure 5 The structure and principle of the air conditioner unit and its air conditioner indoor unit according to the second embodiment of the present invention are shown.

[0075] The difference between the second embodiment and the first embodiment is that the air conditioner indoor unit 1 also includes an auxiliary heat structure, which is used to heat the air entering the casing 11 from the second air return port 112 at least when the indoor heat exchanger 12 is used as an evaporator. return wind.

[0076] During the defrosting process and / or the anti-cold wind process of the air conditioner, if the heat storage structure 14 alone cannot maintain the continuous heating of the room, or the heating cannot reach the required level, the auxiliary heat structure can be used to pass through the second air return port 112 The return air entering the casing 11 is heated, which is more conducive to the continuous heat supply of the air conditioner to the roo...

no. 3 example

[0095] Image 6 The principle of the air conditioning unit of the third embodiment of the present invention is shown.

[0096] like Image 6 As shown, the difference between the third embodiment and the second embodiment is that the air-conditioning indoor unit and the air-conditioning unit of the third embodiment are not provided with an auxiliary throttling device, but the auxiliary heat exchanger 17 and the outdoor heat exchanger 4 are connected in parallel, and the auxiliary heat exchanger 17 and the main circuit of the refrigerant circuit have an access state and a disconnection state.

[0097] like Image 6 As shown, the air conditioner unit in this embodiment includes a compressor 2, a four-way valve 3, an outdoor heat exchanger 4, a main throttling device 5 and an air conditioner indoor unit. The compressor 2, the four-way valve 3, the outdoor heat exchanger 4, the main throttling device 5, the indoor heat exchanger 12 and the auxiliary heat exchanger 17 are connect...

Abstract

The invention discloses an indoor air-conditioner, an air conditioning unit and a control method of the air conditioning unit. The indoor air-conditioner comprises a casing, an indoor draught fan, an indoor heat exchanger and a heat storing structure, wherein a first air returning opening, a second air returning opening and an air outlet are formed in the casing; the first air returning opening and the second air returning opening can be separately arranged in an opening and closing manner; the indoor draught fan is arranged in the casing, and used for blowing out returned air from the air outlet, wherein the returned air enters the casing from the first air returning opening and the second air returning opening; the indoor heat exchanger is arranged in the casing, and positioned in an air channel from the first air returning opening to the air outlet; the heat storing structure is arranged in the casing and positioned in an air channel from the indoor heat exchanger and the second air returning opening to the air outlet. According to the indoor air-conditioner, the air conditioning unit and the control method of the air conditioning unit disclosed by the invention, in the defrosting process and/or cold air preventing process of the air conditioning unit, the comfortableness of a room can be improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning indoor unit, an air conditioning unit and a control method for the air conditioning unit. Background technique [0002] In the prior art, when the heat pump air-conditioning unit is defrosting, the four-way valve is switched during the heating operation of the air-conditioning unit to switch the air-conditioning unit to the cooling operation. During defrosting, the outdoor heat exchanger acts as a condenser, and the indoor heat exchanger acts as an evaporator. The high-temperature and high-pressure refrigerant discharged from the compressor enters the outdoor heat exchanger through the four-way valve to defrost the outdoor heat exchanger. Since the indoor heat exchanger acts as an evaporator during defrosting, the temperature is relatively low, so the indoor fan stops running during defrosting to prevent cold air from being blown into the room. In ad...
