Problems solved by technology

[0003] For example, in dry climate areas, the humidity of the air is low, which sometimes causes discomfort to the human body. Therefore, it is desirable to develop an air-conditioning system with a humidification function
[0004] However, the existing air-conditioning systems usually need to be switched between the mode of cooling the air-conditioned space and the mode of heating the air-conditioned space. If a humidification unit with a humidification heat exchanger is connected to the pipe, the humidification unit will not be able to perform the humidification function in either the cooling mode or the heating mode.

Embodiment approach 1

[0112] First, refer to figure 1 , the circuit configuration of the air conditioning system 1 according to Embodiment 1 of the present invention will be described in detail.

[0113] Such as figure 1 As shown, the air conditioning system 1 of this embodiment includes an outdoor unit 100, a three-pipe indoor unit 200, a humidification unit 300, and at least one (here two, but not limited to) two-pipe indoor units 400A, 400B , the outdoor unit 100, the three-pipe indoor unit 200, the humidifying unit 300, and the two-pipe indoor units 400A, 400B by including the first connecting pipe P1, the second connecting pipe P2, the third connecting pipe P3 and the fourth connecting pipe P4 Multiple connecting pipes are connected to each other.

[0114] Here, stop valves VC1 to VC4 are provided in the middle of the first connection piping P1, the second connection piping P2, the third connection piping P3, and the fourth connection piping P4 (hereinafter, the stop valves VC1 to VC4 are also...

Embodiment approach 2

[0215] Below, refer to Figure 14 The air conditioning system according to Embodiment 2 of the present invention will be described, in which, in Figure 14 In , the same reference numerals are given to the same components as those in Embodiment 1 described above.

[0216] In addition, since the air-conditioning system of this embodiment is basically the same in structure as the air-conditioning system 1 of said Embodiment 1, it demonstrates centering on the difference from said Embodiment 1 below.

[0217] In this embodiment, if Figure 14 As shown, the air conditioning system includes an outdoor unit 100B having the same structure as the outdoor unit 100A in addition to an outdoor unit 100A corresponding to the outdoor unit 100 in Embodiment 1, and these outdoor units 100A, 100B utilize the first connection piping P1, the second connection piping P2, the third connection piping P3, and the third connection piping P4 are mutually connected in parallel.

Abstract

The invention discloses an air-conditioning system and a control method thereof. The humidifying function of each humidifying unit can be achieved in various modes including the refrigeration mode, the heating mode and the like. The air-conditioning system is provided with an outdoor unit, three-tube-type indoor units and the humidifying units which are connected with one another through a first connecting matched pipe, a second connecting matched pipe, a third connecting matched pipe and a fourth connecting matched pipe. The humidifying units are internally provided with humidifying unit siderefrigerating fluid adjusting devices, humidifying unit side heat exchangers, humidifying assemblies and humidifying unit side air supply devices, wherein the humidifying unit side refrigerating fluid adjusting devices and the humidifying unit side heat exchangers are arranged in the midway of a humidifying unit side refrigerating fluid matched pipe. One end of the side, close to the humidifyingunit side refrigerating fluid adjusting devices, of the humidifying unit side refrigerating fluid matched pipe is connected to the portion, located outside the outdoor unit, of the first connecting matched pipe. The other end of the side, close to the humidifying unit side heat exchangers, of the humidifying unit side refrigerating fluid matched pipe is connected to the portion, located outside the outdoor unit, of the fourth connecting matched pipe. The humidifying unit side heat exchangers and the humidifying assemblies are arranged on an airflow circulating path formed by the humidifying unit side air supply devices.

Description

technical field [0001] The invention relates to an air-conditioning system and its control method, in particular to an air-conditioning system including an outdoor unit and a three-pipeline indoor unit and its control method. Background technique [0002] With the improvement of people's living standards, people's demand for living environment control has become increasingly prominent. Therefore, the function of the air conditioning system has gradually developed from a single temperature adjustment to a diversified development. [0003] For example, in dry climate areas, the humidity of the air is low, which sometimes causes discomfort to the human body. Therefore, it is desirable to develop an air-conditioning system with a humidification function. [0004] However, the existing air-conditioning systems usually need to be switched between the mode of cooling the air-conditioned space and the mode of heating the air-conditioned space. If a humidification unit with a humidi...
