Air conditioning device

Abstract

The application provides an air conditioning device, comprising a sensor assembly and a processing unit, wherein the sensor assembly comprises a plurality of ground temperature sensors and an air temperature sensor; the processing unit comprises an estimation unit and a control unit, the estimation unit is configured to estimate an optimal ground temperature estimation value by using a Kalman filter based on the ground temperature detected by each ground temperature sensor, the ground temperature change rate and the air temperature detected by the air temperature sensor; and the control unit is configured to control the operation of the air conditioning device according to input parameters, wherein the input parameters comprise the optimal ground temperature estimation value. The application remotely detects the ground temperature and the air temperature of an air conditioning room by using a plurality of sensors, estimates the optimal ground temperature estimation value by using a Kalman filter, thereby realizing accurate control of the air conditioning device, improving the air conditioning effect, avoiding ground temperature detection failure and reducing energy consumption.
