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

[0136] 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.

[0137] 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 are connected through multiple 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.

[0138] Here, stop valves VC1 to VC3 are provided in the middle of the first connection pipe P1, the second connection pipe P2, and the third connection pipe P3 (hereinafter, the range of the outdoor unit is also delimited by the stop valves VC1 to VC3...

Embodiment approach 2

[0215] 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.

[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 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.

[0218] Specifically, the outdoor unit connectin...

Abstract

The invention discloses an air-conditioning system and a control method thereof. The humidification function of a humidification unit can be exerted in various modes like a refrigeration mode and a heating mode. The air-conditioning system is provided with an outdoor unit, a two-pipe type indoor unit and the humidification unit; the outdoor unit and the two-pipe type indoor unit are mutually connected via a first connecting piping, a second connecting piping and a third connecting piping; a humidification unit side refrigerant adjustment device, a humidification unit side heat exchanger, a humidification assembly and a humidification unit side air supply device are arranged in the humidification unit, wherein the humidification unit side refrigerant adjustment device and the humidificationunit side heat exchanger are arranged at the midway of a humidification unit side refrigerant piping; one end, close to the side of the humidification unit side refrigerant adjustment device, of thehumidification unit side refrigerant piping is connected with the part, located outside the outdoor unit, of the first connecting piping; the other end, close to the side of the humidification unit side heat exchanger, of the humidification unit side refrigerant piping is connected with the part, located outside the outdoor unit, of the third connecting piping; and the humidification unit side heat exchanger and the humidification assembly are arranged in an air flow path formed by the humidification unit side air supply device.

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...
