Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a room air conditioner of the present application, the room air conditioner comprising: the heat exchange unit comprises a first indoor unit heat exchange unit 1, a second indoor unit heat exchange unit 2 and an air outlet unit 3.
The first indoor unit heat exchange unit 1 is arranged in a first area, the first indoor unit heat exchange unit 1 can change air in the first area into first area heat exchange air through an entering first refrigerant, and the temperature and the humidity of the first area heat exchange air are both smaller than those of the first area air; the second indoor unit heat exchange unit 2 is arranged in a second area, the second indoor unit heat exchange unit 2 can change air in the second area into second area heat exchange air through an entering second refrigerant, and the temperature and the humidity of the second area heat exchange air are greater than or equal to those of the second area air; the air outlet unit 3 can mix the first area heat exchange air and the second area heat exchange air, and guide the mixed air out of an air outlet.
In this embodiment, the first indoor unit heat exchange unit 1 and the second indoor unit heat exchange unit 2 are two different heat exchange units, and are respectively disposed in two different areas: a first region and a second region. The first indoor unit heat exchange unit 1 mainly has a cooling and dehumidifying function, i.e., can absorb heat of the air in the first area, separate water from the air in the first area, and provide low-temperature and low-humidity first area heat exchange air (the temperature and humidity of which are both lower than those of the air in the first area). The second indoor heat exchange unit 2 mainly has a heating function, that is, it releases heat to the air in the second area, and provides heat exchange air (the temperature and humidity of which are greater than or equal to those of the air in the second area) in the second area, which has a higher or equal temperature and a higher or equal humidity than the original air (i.e., the air in the second area); it should be noted that if the temperature and humidity of the air in the second area are proper, the heat-exchange air in the second area coming out of the second indoor unit heat exchange unit 2 may be the air in the second area, that is, the heat release from the second indoor unit heat exchange unit 2 to the air in the second area is very small or basically not, and can be ignored. The temperature and humidity of the air in the first zone and the air in the second zone are substantially the same or even before heat exchange, and the temperature and humidity of the heat-exchanged air in the first zone are lower than those of the heat-exchanged air in the second zone.
The first area and the second area can be arranged side by side or arranged up and down; the first area and the second area may be two areas of one indoor unit, or two areas of different indoor units. The specific arrangement of the first and second regions may be determined according to the specific actual application.
The first refrigerant entering the first indoor heat exchange unit 1 and the second refrigerant entering the second indoor heat exchange unit 2 can be independent of each other. The connection relationship may be: the first indoor unit heat exchange unit 1 and the second indoor unit heat exchange unit 2 are respectively connected with the outdoor unit through respective pipelines, and at the moment, the first indoor unit heat exchange unit 1 and the second indoor unit heat exchange unit 2 can work independently.
Alternatively, the first refrigerant entering the first indoor unit heat exchange unit 1 may completely come from the refrigerant coming out of the second indoor unit heat exchange unit 2, and the second refrigerant entering the second indoor unit heat exchange unit 2 comes from the outdoor unit. The connection relationship may be: the second indoor unit heat exchange unit 2 is connected with the outdoor unit through a pipeline, and the first indoor unit heat exchange unit 1 is connected with the second indoor unit heat exchange unit 2 through a pipeline.
The air outlet unit 3 mixes the low-temperature and low-humidity first area heat exchange air with the high-temperature or even second area heat exchange air with high or even moisture content, and the mixed air has moderate temperature and humidity, namely, compared with the low-temperature and low-humidity first area heat exchange air, the mixed air has higher temperature and higher humidity, and compared with the high-temperature or even second area heat exchange air with high or even moisture content and lower temperature and lower humidity, the air outlet comfort can be increased. In practical application, the mixing ratio of the air after cold dehumidification and the hot air can be adjusted, and a multi-dimensional and multi-temperature-field comfortable air supply mode can be obtained.
The air outlet unit 3 may be implemented by mixing the first area heat exchange air and the second area heat exchange air in a special indoor unit air duct system, and then sending the mixed air into a room at an air outlet; or the first area heat exchange air and the second area heat exchange air are independently controlled by air supply in different areas, and are mixed at the air outlet and sent to the room.
An embodiment of the present application provides a room air conditioner, which includes: the first indoor unit heat exchange unit 1 is arranged in a first area, the first indoor unit heat exchange unit 1 can change air in the first area into first area heat exchange air through an entering first refrigerant, and the temperature and the humidity of the first area heat exchange air are both smaller than those of the first area air; the second indoor unit heat exchange unit 2 is arranged in a second area, the second indoor unit heat exchange unit 2 can change air in the second area into second area heat exchange air through an entering second refrigerant, and the temperature and the humidity of the second area heat exchange air are greater than or equal to those of the second area air; and the air outlet unit 3 is used for mixing the first area heat exchange air and the second area heat exchange air and guiding the mixed air out of the air outlet, and the air outlet is formed in the air outlet unit 3. Because the temperature and the humidity of the heat exchange air of the first area are both less than the temperature and the humidity of the air of the first area, the air is the air after the refrigeration and dehumidification of the heat exchange unit 1 of the first indoor unit, the temperature and the humidity of the heat exchange air of the second area are more than or equal to the temperature and the humidity of the air of the second area, the air is the hot air after the heat release of the heat exchange unit 2 of the second indoor unit, the temperature and the humidity of the air of the first area and the air of the second area are basically the same or equal before the heat exchange, and the air of the air outlet is the air after the refrigeration and dehumidification and the air after the hot air are mixed, compared with the existing single-mode refrigeration and dehumidification air supply, the air temperature and the humidity of the air outlet can be improved, the air sent out from the air outlet can not be overcooled and dried, the comfort of the air outlet is increased, if, the comfortable air supply mode with multiple dimensions and multiple temperature fields can be obtained.
In one embodiment, the second refrigerant includes a refrigerant flowing out of the outdoor unit and entering the outdoor unit, and the first refrigerant includes a refrigerant flowing out of the second indoor unit and entering the indoor unit.

In this case, the temperature and pressure reduction unit 4 may adopt a valve 41 with throttling function.

I.e. in different operating modes, different functions of the valve 41 with throttling action can be utilized. In this way, the structure can be simplified, and the cost is saved.

In an embodiment, the room air conditioner further has a heating mode commonly used in cold seasons, that is, in the heating mode, when the high-temperature refrigerant flowing out of the outdoor unit enters from the second indoor unit heat exchange unit 2, the valve 41 having the throttling function does not have the throttling function.
