Problems solved by technology

But this prior art multi-channel air-conditioning system has the following problems: when the user sets different cooling or heating modes on each indoor unit C, in order to switch the cooling or heating mode, the outdoor unit A and the distributor B need to operate the high pressure valve and low pressure valve of the exhaust valve at the same time
Since the high-pressure refrigerant and the low-pressure refrigerant flow at the same time, the pressure difference of the refrigerant will undoubtedly cause vibration and noise of the refrigerant pipe, and will also reduce the life of the devices in the system and their ancillary equipment.
In addition, although this multi-channel air-conditioning system in the prior art can set different cooling or heating modes on each indoor unit, for the same indoor unit, if the operating mode does not need to be changed within a certain period of time, the user You still need to set this mode every time you operate, which will not only bring a lot of inconvenience to the user, but also cause frequent switching of cooling / heating modes due to unfamiliar operation of the user, which will affect the stability of the system

Embodiment Construction

[0023] As shown in FIG. 2 , the multi-channel air conditioning system provided by the present invention mainly includes an indoor unit 70 arranged in each room and an outdoor unit 60 connected to multiple indoor units 70 . The system uses refrigerant pipes to connect compressors, outdoor heat exchangers, and indoor heat exchangers to each other, and absorbs or releases heat through the state changes that occur when the refrigerant passes through the above devices, thereby cooling or heating the indoor space. The outdoor unit 60 and the plurality of indoor units 70 are connected to each other through refrigerant pipes for circulating refrigerant and communication lines for receiving and sending signals. The multi-channel air-conditioning system provided by the present invention also includes an operating mode converter 50 for determining the operating mode. Once the operating mode is selected on the converter, even if another operating command is input on multiple indoor units 7...

Abstract

An air conditioner with multi-path consists of multiple set of indoor unit, outdoor unit connected to those indoor units, operation mode converter connected to outdoor unit and used for setting operation mode by utilizing conversion key to switch refrigerating or heating mode and used for controlling outdoor unit to circulate refrigerant as per set operation mode.

Description

technical field [0001] The present invention relates to a multi-channel air conditioning system, in particular to a multi-channel air conditioning system provided with an operating mode converter for mode switching. Background technique [0002] In general, an air conditioner is a device that cools or heats an indoor space. Recently, a multi-channel air-conditioning system has been widely used. In order to effectively cool or heat multiple indoor spaces divided according to the room, the air-conditioning system is equipped with indoor units in each room, and multiple units are installed at the same time. The indoor unit is connected to an outdoor unit, and distributes and circulates the refrigerant in either cooling or heating operation mode according to the control commands input by each indoor unit, so as to adjust the temperature of the indoor space. Fig. 1 is a schematic diagram of the structure of a multi-channel air conditioning system in the prior art. As shown in F...
