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.

Abstract

The invention relates to an air conditioner refrigerating capacity detection method, a system and an air conditioner, which relate to the technical field of air conditioning. The method comprises the steps of detecting the air dry bulb temperature and relative humidity of an air return inlet of an indoor unit or an outdoor unit of the air conditioner when the air conditioner is operated in a refrigeration mode, and calculating to obtain the air enthalpy of the air return inlet; detecting the air dry bulb temperature and relative humidity of an air outlet of the indoor unit or the outdoor unit of the air conditioner, and calculating to obtain the air enthalpy and wet air density of the air outlet; detecting the air supply speed of the air outlet of the indoor unit or the outdoor unit of the air conditioner; and calculating to obtain the refrigerating capacity of the air conditioner according to the air supply speed, air enthalpy and wet air density of the air outlet, the air enthalpy of the air return inlet and the area, which is measured in advance, of the air outlet. According to the air conditioner refrigerating capacity detection method, the system and the air conditioner, relevant parameters such as temperature, humidity, air speed and the like of the air conditioner are detected, and the refrigerating capacity of the air conditioner is calculated in real time according to the parameters.

Description

technical field [0001] The invention relates to the technical field of air conditioning regulation. Background technique [0002] The cooling capacity stated on the nameplate of the room air conditioner is tested under the conditions specified in the national standard and the specified test method. The capacity is different from that on the nameplate, and its output capacity varies with indoor (outdoor) air temperature, indoor (outside) air humidity, difference between indoor set temperature and actual temperature, power supply (such as power supply voltage), compressor operating frequency, indoor The gear of the external fan, the heat transfer of the heat exchanger and many other factors change, but the specific amount of change and the output capacity are not quantified, and the user does not know at all. In the air conditioner manufacturer, the output capacity cooling capacity (refrigeration capacity) can be quantitatively tested by simulating various use conditions in t...
