Description

Technical Field

[0001] The utility model relates to an independent zoned air conditioning system which uses a refrigerant as floor heating. Background Art

[0002] Floor heating mostly uses floor radiation heating, which can use refrigerant radiation or water circulation radiation.

[0003] The current air conditioners that use refrigerant radiant floor heating cannot independently control the temperature of different rooms, resulting in the inability to shut off the refrigerant flow in some rooms even when the temperature reaches a certain level. This will lead to an increase in additional energy consumption and poor human comfort. Utility Model Content

[0004] In view of the above problems, the utility model provides an independent zoned air-conditioning system using refrigerant as floor heating, which effectively solves the problems pointed out in the background technology.

[0005] The technical solution adopted by the utility model is:

[0006] An independent zoned air conditioning system using refrigerant as floor heating includes an outdoor unit and at least two indoor radiant floor heating terminals. The air pipe port of the outdoor unit is provided with an electric switching valve, the inlet of the electric switching valve is connected to the outdoor unit, the number of outlets of the electric switching valve is the same as the number of indoor radiant floor heating terminals, and the outlets of the electric switching valve are connected to the air pipe ports of the indoor radiant floor heating terminals in a one-to-one correspondence.

[0007] Preferably, each of the indoor radiant floor heating terminals is provided with a wire controller.

[0008] Preferably, the wire controllers are all provided with independent switches.

[0009] The wire controller is used to set the indoor temperature and detect the current indoor temperature. The unit controls the electric switching valve according to the current indoor temperature detected by the wire controller and the set indoor temperature, thereby realizing separate control of each indoor radiant floor heating terminal.

[0010] Preferably, the refrigerant outlet at the end of the indoor radiant floor heating is connected to the liquid pipe stop valve of the outdoor unit through a main liquid pipe.

[0011] Preferably, the indoor radiant floor heating terminal is a floor heating system using refrigerant.

[0012] Preferably, the multiple outlets of the electric switching valve can be cut off and opened separately.

[0013] When the room temperature in the current room reaches the user-set value, the circulation of the refrigerant in the room is cut off. When the room temperature in the current room drops to the start-up set value, the circulation of the refrigerant in the room is opened to heat the room, thus achieving separate temperature control for each room.

[0014] The utility model realizes the separate control of the refrigerant in each indoor radiant floor heating terminal through the electric switching valve, thereby realizing independent temperature control of each room, which not only improves the comfort but also reduces the energy consumption.

[0019] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more, unless otherwise clearly defined.

[0020] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0022] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, an independent zoned air-conditioning system using refrigerant as floor heating includes an outdoor unit 1 and at least two indoor radiant floor heating terminals 2. The air pipe port of the outdoor unit 1 is provided with an electric switching valve 3, the inlet of the electric switching valve 3 is connected to the outdoor unit 1, the number of outlets of the electric switching valve 3 is the same as the number of indoor radiant floor heating terminals 2, and the outlets of the electric switching valve 3 are connected to the air pipe ports of the indoor radiant floor heating terminals 2 in a one-to-one correspondence.

[0024] Each of the indoor radiant floor heating terminals 2 is provided with a wire controller, and each of the wire controllers is provided with an independent switch.

[0025] The refrigerant outlet of the indoor radiant floor heating terminal 2 is connected to the liquid pipe stop valve 5 of the outdoor unit 1 through the main liquid pipe 4.

[0026] The indoor radiant floor heating terminal 2 is a floor heating system using refrigerant.

[0027] The multiple outlets of the electric switching valve 3 can be cut off and opened respectively.

[0028] The utility model collects the current ambient temperature of each room in the room through a wire controller. If the temperature of room A rises to be equal to the actual temperature currently detected by the wire controller, the A port of the electric switching valve 3 is closed. If room B also reaches the temperature, the B port is closed. That is, each room corresponds to an outlet of the electric switching valve 3. If all the rooms reach the temperature, the outdoor host stops running.

[0029] The working principle of the electric switching valve 3 is as follows:

[0030] When the outlet of the electric switching valve 3 is opened, the valve core port is completely connected with the indoor radiant floor heating terminal 2, so that the high-temperature gas compressed by the outdoor unit 1 enters the indoor radiant floor heating terminal 2 to provide heating for the room floor. When the indoor temperature rises to the temperature set by the wire controller, the valve core port of the electric switching valve 3 rotates 90 degrees to avoid the interface with the valve core port 1, thereby preventing the circulation of the refrigerant and achieving the purpose of cutting off.

[0031] Finally, it should be noted that the above examples are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. All variations that can be directly derived or associated with the content disclosed by a person skilled in the art from the present invention should be considered as the protection scope of the present invention.
