Description

Technical Field

[0001] The invention relates to the technical field of air treatment equipment, in particular to an indoor unit and an air conditioner with high heat exchange effect. Background Art

[0002] Existing indoor units (especially American household indoor units) have two installation methods: vertical installation and horizontal installation, but there is only one internal diverter. When the horizontal diverter is separating the liquid, the liquid refrigerant inside it will be affected by gravity and be located below the diverter, while the gaseous refrigerant will be suspended above the diverter, causing the refrigerant discharged from the diverter outlet to be in different states, which will affect the heat exchange effect of the heat exchanger, making it impossible to take into account both installation methods at the same time, resulting in low heat exchange efficiency. Summary of the invention

[0003] In order to solve the technical problem in the prior art that the indoor unit has low heat exchange effect due to the diverter, an indoor unit and an air conditioner with high heat exchange effect are provided, in which the diverter state is adjusted according to the installation method.

[0004] An indoor unit has a refrigerant inlet, and further includes a heat exchanger, a first diverter and a second diverter. The first diverter and the second diverter are arranged in parallel between the refrigerant inlet and the heat exchanger, and an angle is formed between the first diverter and the second diverter.

[0005] The first diverter is arranged horizontally, and the second diverter is arranged vertically.

[0006] A first valve is provided between the first diverter and the refrigerant inlet, and a second valve is provided between the second diverter and the refrigerant inlet. The working state of the first valve is opposite to the working state of the second valve body.

[0007] The indoor unit has a vertical installation mode and a horizontal installation mode:

[0008] In the vertical installation mode, the second valve is in a connected state, and the first valve is in a disconnected state;

[0009] In the horizontal installation mode, the first valve is in a connected state, and the second valve is in a disconnected state.

[0010] The heat exchanger is provided with a plurality of liquid inlets, the outlet of the first flow divider is connected to all the liquid inlets in a one-to-one correspondence, and the outlet of the second flow divider is connected to all the liquid inlets in a one-to-one correspondence.

[0011] An air conditioner comprises the indoor unit mentioned above.

[0012] A control method for the indoor unit as described above includes:

[0013] S1. Obtain the installation method of the indoor unit;

[0014] S2. Control the working state of the first splitter and the working state of the second splitter according to the installation mode obtained in step S1.

[0015] The indoor unit and air conditioner with high heat exchange effect provided by the present invention select a diverter for diversion according to the installation method, thereby ensuring that the refrigerant entering the diverter pipe can be evenly distributed and the refrigerant enters the heat exchanger, so that the heat exchanger can ensure the heat exchange efficiency and effectively avoid the problem of condensation blowing in the indoor unit caused by uneven heat exchange.

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] like Figure 1 and Figure 2 The indoor unit shown in the figure has a refrigerant inlet, and also includes a heat exchanger 1, a first diverter 2 and a second diverter 3. The first diverter 2 and the second diverter 3 are arranged in parallel between the refrigerant inlet and the heat exchanger 1, and an angle is formed between the first diverter 2 and the second diverter 3, so that the indoor unit can perform a normal diversion process in a vertical installation or a horizontal installation, thereby ensuring that the heat exchanger 1 of the indoor unit can perform normal heat exchange, thereby ensuring the heat exchange efficiency of the indoor unit, and avoiding the condensation blowing problem caused by uneven refrigerant distribution.

[0022] The first diverter 2 is arranged horizontally, and the second diverter 3 is arranged vertically, that is, a right angle is formed between the first diverter 2 and the second diverter 3 .

[0023] A first valve 4 is arranged between the first diverter 2 and the refrigerant inlet, and a second valve 5 is arranged between the second diverter 3 and the refrigerant inlet. The working state of the first valve 4 is opposite to the working state of the second valve 5, that is, when the first valve 4 is in an open state, the second valve 5 is in a disconnected state, so that the refrigerant can flow from the refrigerant inlet into the first diverter 2 for diversion without flowing through the second diverter 3. Conversely, when the second valve 5 is in an open state, the first valve 4 is in an open state, and the refrigerant can flow from the refrigerant inlet into the second diverter 3 for diversion without flowing through the first diverter 2.

[0024] The indoor unit has a vertical installation mode and a horizontal installation mode:

[0025] In order to always ensure that the diverter for diversion is in a vertical state so that the gaseous refrigerant and liquid refrigerant inside it are evenly distributed, in the vertical installation mode, the second valve 5 is in a connected state and the first valve 4 is in a disconnected state; at this time, the second valve 5 is in a vertically placed state, and in the horizontal installation mode, the first valve 4 is in a connected state and the second valve 5 is in a disconnected state, and at this time, the first valve 4 is in a vertically placed state.

[0026] The heat exchanger 1 is provided with multiple liquid inlets, the outlet of the first diverter 2 is connected to all the liquid inlets in a one-to-one correspondence, and the outlet of the second diverter 3 is connected to all the liquid inlets in a one-to-one correspondence, that is, the first diverter 2 and the second diverter 3 can both meet the liquid supply demand of the heat exchanger 1.

[0027] An air conditioner comprises the indoor unit mentioned above.

[0028] A control method for the indoor unit as described above includes:

[0029] S1. Obtaining the installation method of the indoor unit, wherein the obtaining method may be a manual input installation method, or may be a method such as setting a gravity sensor on the indoor unit, by obtaining the gravity parameters or state parameters of the indoor unit after installation;

[0030] S2. Control the working state of the first diverter 2 and the working state of the second diverter 3 according to the installation mode obtained in step S1, that is, control whether the first diverter 2 and the second diverter 3 perform diversion, so as to achieve the purpose of controlling the diversion effect.

[0031] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
