in one specific implementation, the operating conditions of the air conditioner may be monitored by providing various sensors. And acquiring the current ambient temperature, the current coil temperature of the heat exchanger, the current temperature of a target pipeline corresponding to the heat exchanger and the current pressure of the target pipeline. The target pipeline is a pipeline for connecting the heat exchanger and the compressor.
Specifically, an intake pressure sensor, an exhaust pressure sensor, an indoor temperature sensor, an outdoor temperature sensor, an indoor coil sensor, an outdoor coil sensor, an intake temperature sensor, an exhaust temperature sensor, and the like may be provided. The system comprises a suction pressure sensor, a discharge pressure sensor, an indoor temperature sensor, an outdoor temperature sensor, an indoor coil sensor, an outdoor temperature sensor, a discharge temperature sensor and a suction temperature sensor, wherein the suction pressure sensor and the discharge pressure sensor are used for detecting system pressure (pressure on a pipeline of a heat exchanger connected with a compressor), and the indoor temperature sensor, the outdoor temperature sensor, the indoor coil sensor, the outdoor temperature sensor, the discharge temperature sensor and the suction temperature sensor are used for various temperatures.
When the heat exchanger is an outdoor heat exchanger, the target pipeline is in management of connection with the exhaust port of the compressor, namely, the heat exchanger is connected with the exhaust port of the compressor through the target pipeline. At this time, the current coil temperature includes a current outer coil temperature, the current temperature of the target line includes a discharge temperature of the compressor, and the current pressure of the target line includes a discharge pressure of the compressor.
When the heat exchanger is an indoor heat exchanger, the target pipeline is managed to be connected with the air suction port of the compressor, namely the heat exchanger is connected with the air inlet of the compressor through the target pipeline; at this time, the current coil temperature includes a current inner coil temperature, the current temperature of the target line includes a suction temperature of the compressor, and the current pressure of the target line includes a suction pressure of the compressor.
Step 102, calculating a first temperature difference between the current coil temperature and the current temperature of the target pipeline, a second temperature difference between the first temperature difference and a pre-stored standard temperature difference at the current environment temperature, a third temperature difference between the current coil temperature and the pre-stored standard coil temperature at the current environment temperature, and a pressure difference between the current pressure of the target pipeline and the pre-stored standard pressure at the current environment temperature;

In general, the first temperature threshold corresponding to the outdoor heat exchanger may be greater than the first temperature threshold corresponding to the indoor heat exchanger, e.g., the first temperature threshold corresponding to the outdoor heat exchanger may be 5, and the first temperature threshold corresponding to the indoor heat exchanger may be 2. The second temperature threshold corresponding to the outdoor heat exchanger may be equal to the second temperature threshold corresponding to the indoor heat exchanger, e.g., the second temperature threshold corresponding to the outdoor heat exchanger and the second temperature threshold corresponding to the indoor heat exchanger may both be 2. The pressure threshold corresponding to the outdoor heat exchanger may be greater than the pressure threshold corresponding to the indoor heat exchanger, e.g., the pressure threshold corresponding to the outdoor heat exchanger may be 0.8 and the pressure threshold corresponding to the indoor heat exchanger may be 0.2.
Step 104, if the pressure difference is greater than or equal to a pressure threshold corresponding to the heat exchanger, determining that the heat exchanger is blocked.
In a specific implementation process, if the pressure difference is greater than or equal to a pressure threshold value corresponding to the heat exchanger, it can be determined that the heat exchanger is dirty and blocked, so that dirty and blocked prompt information can be output, and/or a self-cleaning mode is entered, and the phenomenon of cleaning lag or excessive cleaning of the heat exchanger is reduced.
In a specific implementation process, if the pressure difference is smaller than a pressure threshold corresponding to the heat exchanger, it may be determined that no filth blockage exists in the heat exchanger.
In a specific implementation process, if the second temperature difference is smaller than the first temperature threshold corresponding to the heat exchanger, and/or the third temperature difference is smaller than the second temperature threshold corresponding to the heat exchanger, it may also be determined that there is no filth blockage in the heat exchanger, and at this time, a process of detecting whether the pressure difference is smaller than the pressure threshold corresponding to the heat exchanger is not performed.
According to the heat exchanger filth blocking monitoring method, a current environment temperature, a current coil temperature of a heat exchanger, a current temperature of a target pipeline corresponding to the heat exchanger and a current pressure of the target pipeline are obtained, a first temperature difference between the current coil temperature and the current temperature of the target pipeline, a second temperature difference between the first temperature difference and a pre-stored standard temperature difference under the current environment temperature, a third temperature difference between the current coil temperature and the pre-stored standard coil temperature under the current environment temperature, and a pressure difference between the current pressure of the target pipeline and the pre-stored standard pressure under the current environment temperature are calculated; if the second temperature difference is greater than or equal to the first temperature threshold corresponding to the heat exchanger, the third temperature difference is greater than or equal to the second temperature threshold corresponding to the heat exchanger, and the pressure difference is greater than or equal to the pressure threshold corresponding to the heat exchanger, the fact that the heat exchanger is dirty and blocked is determined, the dirty and blocked state of the heat exchanger is automatically detected, and accordingly the heat exchanger is automatically cleaned or a user is reminded to clean the heat exchanger in a follow-up mode, cleaning lag or excessive cleaning phenomenon of the heat exchanger is reduced, energy waste is reduced, air conditioner energy consumption is reduced, and air conditioner operation effects are improved.
