Problems solved by technology

[0002] In the related art, the vapor compression refrigeration air conditioner is designed to match the area of ​​the room when the air conditioner is started, so that the air conditioner can make the whole room enter the temperature equilibrium state (reach the set temperature) as soon as possible, resulting in a The outlet air temperature cannot meet the user's requirements
[0003] The traditional improvement schemes for cooling and heating speeds that cannot meet the requirements generally use a single compressor with a large displacement or a single compressor with two cylinders. Although this type of air conditioner can meet the temperature rise and fall speed when the air conditioner is started , but due to the increase of its own power, it cannot guarantee energy-saving operation for a period of time after startup

Embodiment 1

[0089] Such as figure 1 , image 3 As shown, in this embodiment, the air conditioning system 100 according to Embodiment 1 of the present invention may include: a first compressor 110, an outdoor unit 120, a throttling device 130, an indoor unit 140, a second compressor 150, and a four-way valve 170 and the first on-off valve 180.

[0090]Wherein, the first compressor 110 has a first inlet 111 and a first outlet 112 , the outdoor unit 120 has a first outdoor unit opening 121 and a second outdoor unit opening 122 , the first outdoor unit opening 121 and the first outdoor unit opening 121 of the first compressor 110 An outlet 112 communicates. Optionally, the outdoor unit 120 may be an outdoor heat exchanger. The throttling device 130 has a first opening 131 and a second opening 132 , and the first opening 131 of the throttling device 130 communicates with the second outdoor unit opening 122 . The indoor unit 140 has a first indoor unit opening 141 and a second indoor unit o...

Embodiment 2

[0123] Such as figure 2 As shown, the difference from Embodiment 1 is that in this embodiment, the air conditioning system 100 may also include a second on-off valve 190 for connecting or blocking the pipeline where it is located, and the second on-off valve 190 has a third port 191 and the fourth port 192, the third port 191 of the second on-off valve 190 is connected between the first port 181 of the first on-off valve 180 and the second outlet 152 of the second compressor 150, the second on-off valve The fourth port 192 of 190 is connected between the fourth valve port and the opening 142 of the second indoor unit. Optionally, the second on-off valve 190 is a solenoid valve, thereby facilitating automatic control of the time air conditioning system 100 .

[0124] Such as Figure 2-Figure 3 As shown, the air-conditioning system 100 is in cooling mode, and the second on-off valve 190 is always in the cut-off state. When the first on-off valve 180 is in the cut-off state, t...

Abstract

The invention discloses an air-conditioning system and a control method of the air-conditioning system. Wherein, the air conditioning system includes: a first compressor, an outdoor unit, a throttling device, an indoor unit and a second compressor with a second inlet and a second outlet. The second inlet of the second compressor is connected between the second opening of the throttling device and the opening of the first indoor unit; it is used to connect or cut off the first on-off valve of the pipeline where it is located, and the first on-off valve has a first port and the second port, the first port of the first on-off valve communicates with the second outlet of the second compressor, the second port of the first on-off valve is connected to the first outlet of the first compressor and the first outdoor unit between openings. According to the air-conditioning system of the present invention, by arranging the first compressor and the second compressor in the air-conditioning system, the pressure of the air-conditioning system can be quickly built up, so that the indoor temperature can reach the expected temperature faster, and the first compressor can be reduced at the same time. Compressor noise.

Description

technical field [0001] The invention relates to the field of household electrical appliances, in particular to an air-conditioning system and a control method for the air-conditioning system. Background technique [0002] In the related art, the vapor compression refrigeration air conditioner is designed to match the area of ​​the room when it is started, so that the air conditioner can make the whole room enter the temperature equilibrium state (reach the set temperature) as soon as possible, resulting in a The outlet air temperature at this time cannot meet the user's requirements. [0003] The traditional improvement schemes for cooling and heating speeds that cannot meet the requirements generally use a single compressor with a large displacement or a single compressor with two cylinders. Although this type of air conditioner can meet the temperature rise and temperature drop speed when the air conditioner is started , but due to the increase in its own power, it cannot...
