  • Heating control method and device for air conditioner
    Patent number: 10830471
    Abstract: An air conditioner heating mode control method includes: obtaining an indoor temperature and comparing the indoor temperature with a first indoor temperature threshold as an air conditioner running at the heating mode; performing a dual PID control process if the indoor temperature is less than or equal to the first indoor temperature threshold. The dual PID control process obtains an indoor temperature difference; performs a PID calculation according to the indoor temperature difference to obtain a first target frequency; obtains a coil temperature difference; performs a PID calculation according to the coil temperature difference to obtain a second target frequency; compares the first and second target frequencies; and performs a frequency control on the compressor in which the greater one between the first target frequency and the second target frequency is used as the target frequency. The present invention includes an air conditioner heating mode control device.
