Abstract

The present disclosure provides an inverter air conditioner control device based on a thermolator, which includes: a first controller, and an input interface, an outdoor unit communicating interface and a detecting interface all connected with the first controller, and an indoor unit controlled by a second controller, wherein, the input interface is connected with the thermolator, receives a control signal sent by the thermolator; the detecting interface is connected with a temperature detector, receives an indoor temperature signal; the first controller connects with a inverter air conditioner outdoor unit, controls an operation of the inverter air conditioner outdoor unit; the first controller sets a target reference temperature which is used for adjusting an operation frequency of a compressor of the inverter air conditioner outdoor unit. The present disclosure also provides a terminal, an inverter air conditioner control system and control method based on the thermolator.

Dependent claims

An inverter air conditioner control device comprising:

an outdoor unit communicating interface;
and
a controller, the controller being coupled to an outdoor unit through the outdoor unit communicating interface, being coupled to a thermolator, being coupled to a temperature sensor, and being configured to:
in response to receiving a shutdown control signal sent by the thermolator:
control a compressor of the outdoor unit to shut down;
record an indoor temperature signal sent from the temperature sensor;
and
set an indoor temperature corresponding to the recorded indoor temperature signal as a target reference temperature;
and
in response to the compressor of the outdoor unit being booted up again after being shut down to start a cooling operation and before receiving a signal to turn off the compressor of the outdoor unit:
obtain an initial indoor temperature at the time of booting up again;
set an initial operation frequency of the compressor of the outdoor unit based on the initial indoor temperature and the target reference temperature that was set to be the indoor temperature acquired when the outdoor unit was shut down last time, the initial operation frequency being positively correlated to a difference between the initial indoor temperature and the target reference temperature;
continue to monitor an indoor temperature;
and
in response to a difference between the monitored indoor temperature and the target reference temperature being smaller than a threshold, reduce an operation frequency of the compressor.
