  • Patent number: 11397010
    Abstract: The present disclosure discloses a heating adjustment method and device, which belongs to the field of thermal system management technologies. The method includes: calculating an average indoor temperature of a cell, wherein the average indoor temperature of the cell is an average value of a real-time indoor temperature of each dwelling unit in the cell; judging whether the average indoor temperature is within a standard temperature range; and adjusting at least one of a water pump flow and a water temperature supplied to the cell when the average indoor temperature is not within the standard temperature range. When the average indoor temperature of the current cell is abnormal, the temperature of the cell is restored to a standard value by adjusting the water pump flow and the water temperature for heating, thus the response speed is fast, the reliability is high, the user experience is improved and energy is saved.

  • Patent number: 11391477
    Abstract: A method and a device for controlling self-cleaning of an air conditioner are provided. The method comprises: acquiring operation duration, operation status parameters and air quality parameters of an air conditioner; determining an equivalent operation duration for the air conditioner according to the operation duration, operation status parameters and air quality parameters of the air conditioner; and controlling the air conditioner to perform self-cleaning when the equivalent operation duration for the air conditioner is greater than a cleaning duration threshold value. The method may prevent a problem of delayed cleaning or premature cleaning of the air conditioner which is caused by pre-estimating a self-cleaning frequency merely according to one variable which is a booting duration.

  • Patent number: 10890347
    Abstract: Provided are a method and device for controlling an air conditioner. The method comprises: acquiring a current indoor temperature in an air conditioner control region and an initial user-set temperature of the air conditioner; and adjusting the initial user-set temperature when an indoor temperature is detected to meet a preset condition, energy consumption corresponding to the adjusted set temperature being lower than energy consumption corresponding to the initial user-set temperature. The method reduces power consumption of the air conditioner while ensuring that the temperature of the air conditioner is basically in line with expectations.
