Embodiment 1
[0061] Such as figure 1 As shown, this embodiment proposes a method for detecting the cooling capacity of the air conditioner. Before the detection, it is firstly detected whether the air conditioner is running in the cooling mode. When the air conditioner is in the cooling mode, the cooling capacity detection is performed; capacity detection; the specific cooling capacity detection process is:
[0062] S1. Detect the dry-bulb temperature and relative humidity of the air at the return air outlet of the indoor unit or outdoor unit of the air conditioner, and calculate the air enthalpy at the return air outlet;
[0063] S2. When the air conditioner is running in the cooling mode, detect the dry bulb temperature and relative humidity of the air at the air supply outlet of the air conditioner indoor unit or outdoor unit, and calculate the air enthalpy and wet air density at the air supply outlet;
[0064] S3, detecting the air supply speed of the air supply outlet of the air cond...
Embodiment 2
[0080] Such as figure 2 As shown, this embodiment proposes an air-conditioning cooling capacity detection system, the system includes:
[0081] The mode detection module is used to detect whether the air conditioner is running in the cooling mode, if yes, the cooling capacity detection is performed, and if not, the cooling capacity detection is performed until it is detected that the air conditioner is running in the cooling mode;
[0082] The return air outlet detection and calculation module is used to detect the dry bulb temperature and relative humidity of the air at the air return outlet of the indoor unit or outdoor unit of the air conditioner, and calculate the air enthalpy at the return air outlet;
[0083] The air supply outlet detection and calculation module is used to detect the air dry bulb temperature and relative humidity of the air supply outlet of the air conditioner indoor unit or outdoor unit when the air conditioner is running in cooling mode, and calculat...
Embodiment 3
[0100] This embodiment proposes an air conditioner, the air conditioner includes the above-mentioned system for detecting cooling capacity of the air conditioner. Both the air return port and the air supply port of the air conditioner are equipped with temperature and humidity sensors, which are used to detect the dry bulb temperature and relative humidity of the air at the return air port and the air supply port respectively. The air supply speed, and the average value of the air supply speed detected by each speed sensor.
[0101] The calculation process of the cooling capacity of the air conditioner can be performed in the controller inside the air conditioner, and the controller samples and calculates the cooling capacity of the air conditioner every 60s to 120s.
