The fan coil unit and air-conditioning unit provided by the present invention, by setting the shell between the adjacent first space 101 and the second space 102, the first space 101 and the second space 102 can be connected through the shell and gas exchange can be performed, thereby realizing the adjustment of the gas composition in the first space 101 and the second space 102, avoiding the problem of increased cost in the prior art that fresh air can only be introduced by setting a fresh air structure, and the shell can inhale gas from the first space 101 and the second space 102 through the first air inlet 13 and the second air inlet 15 respectively, and send gas to the first space 101 and the second space 102 through the first air outlet 14 and the second air outlet 16 respectively, and the gas can be sent to the first space 101 and / or the second space 102 as needed after heat exchange in the shell, so that the fan coil unit can perform heat exchange for both spaces, avoiding the problem of needing to set two fan coil units for the two spaces in the prior art, further reducing the use cost, and can also increase the amount of gas entering the shell, further improve the heat exchange efficiency of the fan coil unit, and improve user experience.

[0044] Specifically, when the first space 101 and the second space 102 both need to exchange heat, the first air inlet 13, the first air outlet 14, the second air inlet 15 and the second air outlet 16 can all be opened, and the fan assembly starts to work, so that the gas in the first space 101 is sucked into the shell through the first air inlet 13, and the gas in the second space 102 is sucked into the shell through the second air inlet 15. After the gas exchanges heat in the shell, the gas is respectively sent to the first space 101 and the second space 102 through the first air outlet 14 and the second air outlet 16, thereby achieving the purpose of simultaneously exchanging heat between the first space 101 and the second space 102;

[0045] When only the first space 101 needs heat exchange, the first air inlet 13 and the first air outlet 14 can be opened, the second air outlet 16 can be closed, and the fan assembly starts to work, so that the gas in the first space 101 is sucked into the shell through the first air inlet 13, and then the gas is heat exchanged in the shell, and then the gas is sent to the first space 101 through the first air outlet 14, thereby achieving the purpose of heat exchange for the first space 101; wherein, the second air inlet 15 can be manually adjusted according to user needs or automatically adjusted according to preset conditions such as the gas composition in the first space 101 to control opening or closing, and when the second air inlet 15 When the air inlet 15 is opened, the gas in the second space 102 can also enter the shell to participate in heat exchange, and then be sent into the first space 101 through the first air outlet 14, so as to realize the exchange of gas components in the first space 101 and the second space 102, and the gas temperature in the second space 102 can also have a certain heat exchange effect on the first space 101, thereby improving the heat exchange efficiency in the first space 101; and when the second air inlet 15 is closed, the gas in the second space 102 will not enter the shell, and there is no gas flow in the second space 102, thereby avoiding temperature loss in the second space 102;

[0046] Similarly, when only the second space 102 needs heat exchange, the second air inlet 15 and the second air outlet 16 can be opened, the first air outlet 14 can be closed, and the fan assembly starts working, so that the gas in the second space 102 is sucked into the shell through the second air inlet 15, and then the gas is heat exchanged in the shell, and then the gas is sent to the second space 102 through the second air outlet 16, thereby achieving the purpose of heat exchange for the second space 102; wherein, the first air inlet 13 can be manually adjusted according to user needs or automatically adjusted according to preset conditions such as the gas composition in the second space 102 to control opening or closing, when When the first air inlet 13 is opened, the gas in the first space 101 can also enter the shell to participate in heat exchange, and then be sent into the first space 101 through the second air outlet 16, thereby realizing the exchange of gas components in the first space 101 and the second space 102, and the gas temperature in the first space 101 can also have a certain heat exchange effect on the second space 102, thereby improving the heat exchange efficiency in the second space 102; when the first air inlet 13 is closed, the gas in the first space 101 will not enter the shell, and there is no gas flow in the first space 101, thereby avoiding temperature loss in the first space 101.

[0047] Preferably, the first space 101 is located above the second space 102 , the first air inlet 13 and the first air outlet 14 are located at the bottom of the first space 101 , and the second air inlet 15 and the second air outlet 16 are located at the top of the second space 102 . That is, at this time, the fan coil unit is located between the separation position of the first space 101 and the second space 102, and the fan coil unit can supply air from the bottom of the first space 101 to the first space 101, especially when heating, it can quickly send heat to the bottom of the first space 101, which can improve the comfort of the user; and although the second space 102 is heated from the top to the bottom during heating, the heating effect of the second space 102 can still be guaranteed, especially when the second space 102 is a room with a small space size, the heating at the top can still meet the purpose of heating the second space 102, and when cooling, the principle of cold air sinking can be fully utilized, the cold air in the first space 101 will accumulate at the bottom of the first space 101 to improve the cooling effect, and the cold air in the second space 102 will quickly flow to the bottom of the second space 102 under the action of gravity to improve the cooling effect of the second space 102.

[0048] In order to achieve heat exchange of gas, the fan coil unit includes a first heat exchanger 2, which is arranged in the first shell section 11, and the first heat exchanger 2 divides the shell into a fan blade cavity and a first air supply cavity, the fan blade assembly is arranged in the fan blade cavity, the first air inlet 13 and the second air inlet 15 are both connected to the fan blade cavity, and the first air outlet 14 is connected to the first air supply cavity. The gas sucked into the shell through the fan blade assembly will flow through the first heat exchanger 2 for heat exchange when it is discharged through the first air outlet 14, and after heat exchange, it will be sent to the first space 101 through the first air outlet 14 to achieve heat exchange of the first space 101.

[0049] The fan coil unit also includes an air supply pipe 3, which is arranged on the side wall of the first shell section 11, and one end of the air supply pipe 3 is connected to the fan blade cavity, the first air supply port is arranged on the air supply pipe 3, and the first heat exchanger 2 is arranged in the air supply pipe 3. Since the fan coil unit is located on the bottom surface of the first space 101, the air supply pipe 3 is used to increase the distance between the air supply position of the first air supply port and the air intake position of the first air inlet, so as to avoid the first air inlet directly obtaining gas from the first air supply port and failing to reliably exchange heat with the first space 101. In particular, when the fan coil unit is heating, hot air can be supplied from multiple ground positions of the first space 101, thereby improving the heating efficiency in the first space 101 and thus improving the user experience.

[0050] Specifically, the air supply pipe 3 has a first side surface facing the first space 101, and the first air supply port is arranged on the first side surface. The first side surface of the air supply pipe 3 is prevented from being higher than the top surface of the first shell segment 11, so that the bottom surface of the first space 101 is flat, thereby improving user experience.

[0051] The fan coil unit also includes a second heat exchanger 4, which is disposed in the second shell section 12, and the second heat exchanger 4 divides the shell into a blade chamber and a second air supply chamber, the blade assembly is disposed in the blade chamber, the first air inlet 13 and the second air inlet 15 are both connected to the blade chamber, and the second air outlet 16 is connected to the second air supply chamber. The gas sucked into the shell through the blade assembly will flow through the second heat exchanger 4 for heat exchange when it is discharged through the second air outlet 16, and after heat exchange, it will be sent to the second space 102 through the second air outlet 16 to achieve heat exchange for the second space 102.

[0052] The second air inlet 15 and the second air outlet 16 are both located on the bottom surface of the second shell section 12, and the second air outlet 16 is distributed around the second air inlet 15, and the lower end of the second heat exchanger 4 is sealed with the portion of the shell between the second air inlet 15 and the second air outlet 16. This makes it impossible for the gas in the fan cavity to flow directly through the gap between the second air inlet 15 and the second air outlet 16, and the gas must pass through the heat exchange of the second heat exchanger 4 to ensure the heat exchange efficiency of the second space 102.

[0053] Since the fan coil unit is located on the top surface of the second space 102, the second air inlet 15 obtains gas from the top of the second space 102, and the second air outlet 16 delivers gas to the top of the second space 102. At this time, there is a problem that the second air inlet 15 directly obtains gas from the second air outlet 16. For this reason, the second air outlet 16 is arranged on the side of the second air inlet 15, and the air outlet direction of the second air outlet 16 is offset in the direction away from the second air inlet 15. That is, the air inlet direction of the second air inlet 15 is the vertical direction, and the air outlet direction of the second air outlet 16 is inclined relative to the vertical direction.

[0054] The second air outlet 16 is in an elongated shape, which effectively increases the gas flow rate of the second air outlet 16 , further avoids the problem that the second air inlet 15 directly obtains gas from the second air outlet 16 , and can also improve the heat exchange effect in the second space 102 .

[0055] In order to further ensure the heat exchange reliability of the second heat exchanger 4, the fan coil unit further includes a partition plate 5, which is arranged at the connection between the first shell section 11 and the second shell section 12, and the upper end of the second heat exchanger 4 is sealed with the partition plate 5. The upper end of the second heat exchanger 4 is sealed with the partition plate 5, further forcing the gas in the fan blade cavity to flow to the second air outlet 16 only through the second heat exchanger 4, thereby ensuring the reliability of the fan coil unit.

[0056] The fan blade assembly includes a first fan blade 61 and a second fan blade 62, the first fan blade 61 is arranged in the first shell segment 11, and the second fan blade 62 is arranged in the second shell segment 12, the partition plate 5 is located between the first fan blade 61 and the second fan blade 62, and the partition plate 5 will not protrude into the rotating body formed by the first fan blade 61 and the second fan blade 62, thereby ensuring that the first fan blade 61 and the second fan blade 62 can both drive the gas in the fan blade cavity and ensure the working reliability of the fan coil unit.

[0057] The first fan blade 61 and the second fan blade 62 are coaxially arranged, that is, the first fan blade 61 and the second fan blade 62 work simultaneously. Preferably, the fan coil unit further comprises a motor, the motor is arranged in the fan blade cavity, and the rotating shaft of the motor protrudes from both ends of the motor, and the first fan blade 61 and the second fan blade 62 are distributed on both sides of the motor and are both connected to the rotating shaft of the motor.

[0058] A wind valve structure is provided at the first air inlet 13. By setting the wind valve structure, the opening or closing of the first air inlet 13 can be controlled, thereby controlling the working state of the fan coil unit. When the gas in the first space 101 needs to flow or be replaced and the first space 101 needs heat exchange, the first air inlet 13 can be opened, otherwise the first air inlet 13 is closed, thereby improving the user experience.

[0059] The first air outlet 14 is provided with an air valve structure. By providing the air valve structure, the opening or closing of the first air outlet 14 can be controlled, thereby controlling the working state of the fan coil unit. When there is no need to discharge air to the first space 101, the first air outlet 14 can be closed, otherwise it can be opened, thereby improving the user experience.

[0060] The second air inlet 15 is provided with an air valve structure, and the opening or closing of the second air inlet 15 can be controlled by setting the air valve structure, so as to control the working state of the fan coil unit. When the gas in the second space 102 needs to flow or be replaced and the second space 102 needs heat exchange, the second air inlet 15 can be opened, otherwise the second air inlet 15 is closed, thereby improving the user experience.

[0061] The second air outlet 16 is provided with an air valve structure. By providing the air valve structure, the opening or closing of the second air outlet 16 can be controlled, thereby controlling the working state of the fan coil unit. When there is no need to discharge air to the second space 102, the second air outlet 16 can be closed, otherwise the second air outlet 16 can be opened, thereby improving the user experience.

[0062] The fan coil unit has a first space 101 heat exchange mode, a second space 102 heat exchange mode and a full heat exchange mode:

[0063] When the fan coil unit is in the heat exchange mode of the first space 101, the first air outlet 14 is in an open state, the second air outlet 16 is in a closed state, and the fan blade assembly starts to work, so that the gas in the first space 101 is sucked into the shell through the first air inlet 13, and then the gas is heat exchanged in the shell, and then the gas is sent to the first space 101 through the first air outlet 14, so as to achieve the purpose of heat exchange for the first space 101; wherein, the second air inlet 15 can be manually adjusted according to user needs or automatically adjusted according to preset conditions such as the gas composition in the first space 101 to control opening or closing When the second air inlet 15 is opened, the gas in the second space 102 can also enter the shell to participate in heat exchange, and then be sent into the first space 101 through the first air outlet 14, so as to realize the exchange of gas components in the first space 101 and the second space 102, and the gas temperature in the second space 102 can also have a certain heat exchange effect on the first space 101, thereby improving the heat exchange efficiency in the first space 101; and when the second air inlet 15 is closed, the gas in the second space 102 will not enter the shell, and there is no gas flow in the second space 102, thereby avoiding temperature loss in the second space 102;

[0064] When the fan coil unit is in the heat exchange mode of the second space 102, the second air outlet 16 is in an open state, the first air outlet 14 is in a closed state, and the fan blade assembly starts to work, so that the gas in the second space 102 is sucked into the shell through the second air inlet 15, and then the gas is heat exchanged in the shell, and then the gas is sent to the second space 102 through the second air outlet 16, so as to achieve the purpose of heat exchange for the second space 102; wherein, the first air inlet 13 can be manually adjusted according to user needs or automatically adjusted according to preset conditions such as the gas composition in the second space 102 to control opening or closing When the first air inlet 13 is opened, the gas in the first space 101 can also enter the shell to participate in heat exchange, and then be sent into the first space 101 through the second air outlet 16, so as to realize the exchange of gas components in the first space 101 and the second space 102, and the gas temperature in the first space 101 can also have a certain heat exchange effect on the second space 102, thereby improving the heat exchange efficiency in the second space 102; and when the first air inlet 13 is closed, the gas in the first space 101 will not enter the shell, and there is no gas flow in the first space 101, thereby avoiding temperature loss in the first space 101;
