Abstract
Disclosed are a method for controlling a variable refrigerant flow (VRF) air conditioner, a VRF air conditioner, and a computer-readable storage medium. The method includes: obtaining a target indoor unit in a warming stage among started indoor units; determining a target superheat degree according to a working condition parameter of the target indoor unit; and adjusting an operating parameter of an electronic expansion valve of the target indoor unit according to the target superheat degree.
Claims14
A method for controlling a variable refrigerant flow (VRF) air conditioner, comprising:
- obtaining set temperatures and indoor ambient temperatures of respective environments where a plurality of indoor units of the VRF air conditioner that have started are located;
- identifying a target indoor unit of the plurality of indoor units that is in a warming stage based on the indoor ambient temperature of the environment of the target indoor unit being less than or equal to a preset temperature, wherein the preset temperature is greater than the set temperature for the environment of the target indoor unit;
- determining a target superheat degree according to a working condition parameter of the target indoor unit;
- and
- adjusting an operating parameter of an electronic expansion valve of the target indoor unit according to the target superheat degree.
A controller for a variable refrigerant flow (VRF) air conditioner comprising:
- one or more processors;
- and
- a memory storing a program for controlling the VRF air conditioner, wherein the program is executable by the one or more processors to implement a method comprising:
- obtaining set temperatures and indoor ambient temperatures of respective environments where a plurality of indoor units of the VRF air conditioner that have started are located;
- identifying a target indoor unit of the plurality of indoor units that is in a warming stage based on the indoor ambient temperature of the environment of the target indoor unit being less than or equal to a preset temperature, wherein the preset temperature is greater than the set temperature for the environment of the target indoor unit;
- determining a target superheat degree according to a working condition parameter of the target indoor unit;
- and
- adjusting an operating parameter of an electronic expansion valve of the target indoor unit according to the target superheat degree.
A variable refrigerant flow (VRF) air conditioner system comprising:
- at least one outdoor unit;
- a plurality of indoor units;
- and
- a controller comprising:
- one or more processors;
- and
- a memory comprising instructions that, when executed by the one or more processors causes the one or more processors to, when the plurality of indoor units have been started and are operating in a cooling mode:
- obtain set temperatures and indoor ambient temperatures of respective environments where the plurality of indoor units are located;
- identifying a target indoor unit of the plurality of indoor units that is in a warming stage based on the indoor ambient temperature of the environment of the target indoor unit being less than or equal to a preset temperature, wherein the preset temperature is greater than the set temperature for the environment of the target indoor unit;
- determining a target superheat degree according to a working condition parameter of the target indoor unit;
- and
- adjusting an operating parameter of an electronic expansion valve of the target indoor unit according to the target superheat degree.
