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

[0131] First, refer to figure 1 , the circuit structure of the air-conditioning system 1 according to Embodiment 1 of the present invention will be described in detail.

[0132] like figure 1 As shown, the air conditioning system 1 of the present embodiment includes an outdoor unit 100, a three-pipe indoor unit 200, a humidification unit 300, and at least one (two here, but not limited to) two-pipe indoor units 400A, 400B , the outdoor unit 100, the three-pipe type indoor unit 200, the humidifying unit 300, and the two-pipe type indoor units 400A, 400B are connected by a plurality of connections including the first connection pipe P1, the second connection pipe P2, and the third connection pipe P3 The pipes are connected to each other.

[0133] Here, cutoff valves VC1 to VC3 (hereinafter, cutoff valves VC1 to VC3 are also used as boundaries to define the range of the outdoor unit are provided in the middle of the first connection pipe P1, the second connection pipe P2, and t...

Embodiment approach 2

[0210] Below, refer to Figure 9 The air conditioning system according to Embodiment 2 of the present invention will be described, in which, in Figure 9 In , the same reference numerals are given to the same components as those in Embodiment 1 described above.

[0211] 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.

[0212] In this embodiment, if Figure 9 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, and the third connection piping P3 are connected in parallel with each other.

[0213] Specifically, the outdoor unit connectin...

Abstract

An air-conditioning system and a control method thereof can perform the humidification function of the humidification unit in various modes such as cooling mode and heating mode. The air conditioning system of the present invention has an outdoor unit, a two-pipe type indoor unit, and a humidifying unit connected to each other via a first connecting pipe, a second connecting pipe, and a third connecting pipe, and the humidifying unit is provided with: Humidification unit side refrigerant adjustment device and humidification unit side heat exchanger in the middle of refrigerant piping; humidification unit; and humidification unit side air supply device, the end of the humidification unit side refrigerant piping near the humidification unit side refrigerant adjustment device side is connected The part outside the outdoor unit of the first connecting pipe, the other end of the refrigerant pipe on the humidifying unit side near the heat exchanger on the humidifying unit side is connected to the part outside the outdoor unit of the third connecting pipe, and the heat exchange on the humidifying unit side The humidifier and the humidifying component are arranged in the air flow path formed by the side air blower of the humidifying unit.

Description

technical field [0001] The present invention relates to an air conditioning system and a control method thereof, in particular to an air conditioning system including a humidifying unit and a control method thereof. 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 humidification h...
