Abstract

The invention discloses a variable frequency air conditioner and a control method and a control device thereof. The control method is applied to an outdoor unit of the variable frequency air conditioner; no communication exists between the outdoor unit and an indoor unit; and the control method comprises the following steps: a variable frequency compressor is controlled to operate according to aninitial operation frequency; the continuous operation time and the stop working frequency of the variable frequency compressor are monitored; and the operation frequency of the variable frequency compressor is controlled according to the continuous operation time and the stop working frequency. The operation frequency of the variable frequency compressor can be adjusted according to the continuousoperation time and the stop working frequency of the compressor, so that the output capacity of the compressor is changed, no communication between the indoor and outdoor units is guaranteed when theadvantages of higher comfort of the variable frequency air conditioner, higher user experience and the like are considered, the mated use is not needed, and the user selection diversity is improved.

Description

technical field [0001] The present invention relates to the field of unit technology, in particular to an inverter air conditioner and its control method and control device. Background technique [0002] At present, 24V weak current is generally used to control air conditioners exported to North America, Latin America and other regions. Most of the internal and external units of this type of air conditioner are fixed-frequency units, and there is no need for communication between the internal and external units. Therefore, the indoor and outdoor units of different manufacturers can be mixed and matched, thereby increasing the diversity of user choices and reducing the cost of installation and maintenance. However, the indoor unit, outdoor unit and thermostat of fixed-frequency air conditioners are mostly controlled by 24V weak current. The inner unit has no main board and cannot detect the return air temperature and pipe temperature. The external unit cannot detect the indo...
