The application relates to the technical field of air conditioning, and specifically to an air conditioning system and control method thereof.
In the field of air conditioning, a cabinet unit is a commonly used indoor air conditioning internal unit, which comprises a casing, a heat exchanger and a fan mounted inside the casing. The indoor unit and the outdoor unit form an air conditioning system, and the indoor unit is used to supply cooling and heating to the room.
However, the existing indoor units blow cold or hot air into the room through a fan. When the indoor temperature reaches the user's desired temperature, if the fan continues to blow air, it is easy to cause the indoor temperature to be too low or too high. If cold or hot air blows towards the user's body, the user will feel too cold or too hot, resulting in a poor user experience. In the prior art, one way is to use inverter air conditioner to achieve automatic control, however, it completely relies on the fan to achieve. When the temperature reaches the user's preset temperature, the fan is switched off or slowed down, and when the temperature exceeds the preset range, the fan is turned on or accelerated again, and such operation will still cause the indoor temperature to change too quickly, and there is a cold or hot air constantly blowing, affecting the user's experience. In addition, noise will also be produced during the switching on and off process of the fan, affecting the user's sleep.
The application aims to overcome the defects in the prior art, and provide a new air conditioning system and the control method thereof, wherein the casing of the indoor unit is a radiant heat sink, the radiant heat sink may cooperate with a built-in heat exchanger to exchange the heat together in order to adjust the indoor temperature quickly. After the indoor temperature reaches a preset temperature, the built-in heat exchanger is switched off and only the radiant heat dissipation casing is used to dissipate heat, in order to slowly dissipate the heat to the room, to keep the indoor temperature within a certain range, there will be no cold or hot air continuously blowing to the user, and there will be no noise, which enhances the user's experience.

The air conditioning system provides by an embodiment of the application comprises the indoor unit 100, the outdoor unit 200, the medium circulation pipe 300 and the control unit 400.
The indoor unit 100 can be a wall-mounted air conditioner indoor unit or a standing air conditioner indoor unit (cabinet unit). Preferably, the indoor unit 100 is a standing air conditioner indoor unit (cabinet unit), which has a radiant heat dissipation casing 1 with a large area, strong radiation heat exchange capability, and a large space for effective heat exchange.
The outdoor unit 200 is a traditional air conditioner outdoor unit, which has components such as a compressor inside.
The medium circulation pipe 300 is used to circulate heat exchange medium, also called air conditioning medium, for example, Freon.
The control unit 400 is a control module such as a controller or a chip used to control the switching operation of each component. It can be mounted on a panel of the indoor unit 100 or a remote controller may be adopted to achieve control.
Wherein, the indoor unit 100 comprises the radiant heat dissipation casing 1, the built-in heat exchanger 2, the fan 3, etc. The built-in heat exchanger 2 and the fan 3 are mounted in the radiant heat dissipation casing 1. When the built-in heat exchanger 2 is switched on, the fan 3 is switched on synchronously. The built-in heat exchanger 2 is a convection heat exchanger using a conventional fan 3.
The radiant heat dissipation casing 1 is used as a protective casing on the one hand, and as a radiant heat sink or radiant heat exchanger on the other hand. Radiant heat sink or radiant heat exchanger refers to a heat exchanger or heat sink that does not require blowing equipment such as fans and relies solely on its own radiation ability to exchange heat with or dissipate heat to the surrounding air. The heat exchange and heat dissipation referred to in the present application include not only heat energy exchange and heat energy release, but also cold energy exchange and cold energy release, which can realize the functions of indoor cooling and heating.
The radiant heat dissipation casing I comprises the air inlet 11 and the air outlet 12, generally, the air inlet 11 is provided on a back side, a lower side or a side of the radiant heat dissipation casing 1, and the air outlet 12 is provided on a front side or around the radiant heat dissipation casing 1. The air inlet 11 is used for ambient air to enter the radiant heat dissipation casing 1 to exchange heat with the built-in heat exchanger 2 and the entered air is then blown out by the fan 3. The air outlet 12 is used for blowing out the air after heat exchange with the built-in heat exchanger 2. The blowing direction of the fan 3 is directed towards the air outlet 12. The air after heat exchange with the built-in heat exchanger 2 is blown out from the radiant heat dissipation casing 1 under the action of the fan 3, and then directed towards the room.
The air outlet 12 may be configured with a swinging blade, a cover plate, a motor and the like, which may employ the mounting structure of the existing air outlet of the indoor unit in order to realize swinging left and right, up and down to adjust the air direction. The cover plate covers the air outlet 12 after the indoor unit 100 is turned off.
The fan 3 and the built-in heat exchanger 2 are mounted in the radiant heat dissipation casing 1 through a bracket 5, respectively. The fan 3 is optionally mounted between the built-in heat exchanger 2 and the air outlet 12.
The fan 3 is connected with the control unit 400 through a wire for signaling, whereby the control unit 400 controls the switching of the fan 3.
As needed, the fan 3 may be mounted at an angle, such that it is located diagonally above or below the built-in heat exchanger 2 to avoid blocking the built-in heat exchanger 2.
As needed, the fan 3 may employ a roller air wheel, which is arranged and extends along the length direction of the built-in heat exchanger 2 to obtain sufficient air power, so as to blow both cold and hot air from the surface of the built-in heat exchanger 2 towards the air outlet 12.
As needed, an air duct may be connected between the built-in heat exchanger 2 and the air outlet 12, and the fan 3 is mounted in the air duct to reduce the loss of air flow.
As needed, an air duct may also be connected between the built-in heat exchanger 2 and the air inlet 11, which facilitates directing the air into the space where the built-in heat exchanger 2 is located to fully exchange heat.
In this application, the radiant heat dissipation casing 1 has the medium flow channel 13, and the medium flow channel 13 is connected with the medium circulation pipe 300 for circulation of the heat exchange medium for heat exchange with the indoor air or the ambient air, so as to enable the radiant heat dissipation casing 1 to have the function of a radiant heat exchanger or a radiant heat sink. The number or shape of the medium flow channels 13 can be set as needed.
In this application, the radiant heat dissipation casing 1 and the built-in heat exchanger 2 are connected with the medium circulation pipe 300 respectively, and the radiant heat dissipation casing 1 is arranged in parallel with the built-in heat exchanger 2. The indoor unit 100 and the outdoor unit 200 are connected with the control unit 400 through a wire for signaling, whereby the control unit 400 controls the switching of the indoor unit 100 and the outdoor unit 200.
The built-in heat exchanger 2 is connected with the medium circulation pipe 300, so that when the outdoor unit 200 is switched on, the heat exchange medium may enter into the heat exchanger flow path of the built-in heat exchanger 2 in order to exchange heat with the air that enters into the radiant heat dissipation casing 1 or the air that enters into the space in which the built-in heat exchanger 2 is located, and after heat exchange, the air is blown out of the air outlet 12 by the fan 3.
In this application, the air that enters the radiant heat dissipation casing 1 or the air that enters the space where the built-in heat exchanger 2 is located is referred to as fresh air or return air.
The medium flow channel 13 is connected with the medium circulation pipe 300, so that when the outdoor unit 200 is switched on, the heat exchange medium may enter into the medium flow channel 13 of the radiant heat dissipation casing 1 in order to exchange heat with the indoor air or ambient air, and utilize its own radiation ability to cool down or warm up the ambient air around it, so that there will not be a cold air or a hot air blowing to the user, and there will be no noise from the switching on of the fan, blower, and other devices.
As needed, corresponding control valves can be configured in the medium circulation pipe 300, the built-in heat exchanger 2, and the radiant heat dissipation casing 1 to control the circulation of the heat exchange medium, thereby controlling the operation state of the radiant heat dissipation casing 4 and the built-in heat exchanger 2.
When the built-in heat exchanger 2 and the radiant heat dissipation casing 1 supply cooling to the room, the built-in heat exchanger 2 and the radiant heat dissipation casing 1 are used as an evaporator.
When the built-in heat exchanger 2 and the radiant heat dissipation casing 1 supply heat to the room, the built-in heat exchanger 2 and the radiant heat dissipation casing 1 are used as a condenser.
The above switching method can be realized by configuring a four-way reversing valve in the outdoor unit 200, and the four-way reversing valve is in the prior art and will not be repeated herein.
Hereby, an air conditioning system provided by the application can realize the mode of simultaneously turning on the radiant heat dissipation casing 1 and the built-in heat exchanger 2, the mode of solely turning on the built-in heat exchanger 2 and the mode of solely turning on the radiant heat dissipation casing 1.
For case of description, in this application, the mode of turning on the radiant heat dissipation casing 1 and the built-in heat exchanger 2 is called a first operation mode of the indoor unit 100, the mode of solely turning on the built-in heat exchanger 2 is called a second operation mode of the indoor unit 100, and the mode of solely turning on the radiant heat dissipation casing 1 is called a third operation mode of the indoor unit 100, so that the user can choose from a number of modes, which meets the needs of different operation conditions.
When users need to quickly adjust the indoor temperature, they can optionally switch on the radiant heat dissipation casing 1 and the built-in heat exchanger 2 at the same time, and the radiant heat dissipation casing 1 and the built-in heat exchanger 2 will exchange heat or dissipate heat together to quickly adjust the indoor temperature. If the indoor temperature is within a certain range, and the user feels that current demand for heat exchange can be satisfied solely by the built-in heat exchanger 2, users can choose to separately use the built-in heat exchanger 2 to adjust the indoor temperature to meet the needs of different users and operation conditions. After the indoor temperature reaches the preset temperature, users can choose to switch off the built-in heat exchanger 2 and keep the radiant heat dissipation casing 1 on, dissipating heat only through the radiant heat dissipation casing 1, in order to slowly dissipate the heat to the room, to keep the indoor temperature within a certain range, there will be no cold or hot air continuously blowing to the user, and there will be no noise, which enhances the user's experience.
Take cooling and decreasing the temperature as an example:
If the indoor temperature exceeds 30° C. (the temperature threshold, which can be chosen by the users themselves), then the first operation mode can be selectively employed, although the radiation heat dissipation casing 1 exchanges heat relatively slowly compared with the built-in heat exchanger 2, it plays a role in assisting the heat exchange and cooling, and also enhancing the efficiency or effect of indoor cooling.
If the indoor temperature is between 26° C. to 28° C. (the temperature threshold, which can be chosen by the users themselves), some users may feel hot, and some users may feel only slightly hot, so the user can choose to solely turn on the built-in heat exchanger 2 to slightly faster the cooling, or solely turn on the radiant heat dissipation casing 1 for slowly cooling, it can meet the different needs for different users, the workload of the outdoor unit 200 will not be in a fully loaded state and there is also a power saving effect.
If the indoor temperature is already between 22° C. to 26° C. (the temperature threshold, which can be chosen by the users themselves), most of the users feel that the body temperature under this temperature is more appropriate. In order to avoid the cold air blowing to the user, especially blowing to the infants and young children, the third operation mode may be chosen, dissipating heat only through the radiant heat dissipation casing 1, in order to slowly dissipate the heat to the room, to keep the indoor temperature within a certain range. There will be no cold air continuously blowing to the user, and there will be no noise, which enhances the user's experience.
Take heating and increasing the temperature as an example:
If the indoor temperature is below 16° C. (the temperature threshold, which can be chosen by the users themselves), then the first operation mode can be selectively employed, although the radiation heat dissipation casing 1 exchanges heat relatively slowly compared with the built-in heat exchanger 2, it plays a role in assisting the heat exchange and heating, and also enhancing the efficiency or effect of indoor heating.
If the indoor temperature is between 19° C. to 22° C. (the temperature threshold, which can be chosen by the users themselves), some users may feel slightly cold, and some users may feel it is warm enough, so the user can choose to solely turn on the built-in heat exchanger 2 to slightly faster the heating, or solely turn on the radiant heat dissipation casing 1 for slowly heating, it can meet the different needs for different users, the workload of the outdoor unit 200 will not be in a fully loaded state and there is also a power saving effect.
If the indoor temperature is already between 22° C. to 25° C. (the temperature threshold, which can be chosen by the users themselves), most of the users feel that the body temperature under this temperature is more appropriate. In order to avoid the warm air blowing to the user directly, especially blowing to the infants and young children, the third operation mode may be chosen, dissipating heat only through the radiant heat dissipation casing 1, in order to slowly dissipate the heat to the room, to keep the indoor temperature within a certain range. There will be no warm air continuously blowing to the user, and there will be no noise, which enhances the user's experience.
