Air-conditioning refrigerant leakage detection method, device, storage device, terminal, and air-conditioning

Abstract

The invention discloses a refrigerant leakage detection method and device for an air conditioner, a storage device, a terminal and the air conditioner. The method comprises the steps of acquiring the current operation state parameter of the air conditioner; determining the reference temperature difference of the air conditioner according to the current operation state parameter and determining the heat exchange temperature difference between a compressor and a heat exchanger of the air conditioner; and determining the refrigerant leakage ratio of the air conditioner according to the difference value between the heat exchange temperature difference and the reference temperature difference as well as a set calculation coefficient. According to the scheme of the refrigerant leakage detection method and device for the air conditioner, the storage device, the terminal and the air conditioner, the defects of high detection difficulty, poor protection timeliness, short service life and the like in the prior art can be overcome, and the beneficial effects of low detection difficulty, good protection timeliness and long service life can be achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically relates to a refrigerant leakage detection method, device, storage device, terminal and air conditioner for an air conditioner, and in particular to a method for detecting fluorine leakage of a constant speed air conditioner, a device corresponding to the method, and a device storing the A storage device for the method, a terminal capable of executing the method, and an air conditioner having the device or the storage device. Background technique [0002] A fixed-frequency air conditioner is a unit used to provide a space area (generally a closed space) to deal with changes in air temperature. The fixed-frequency air conditioner has fewer operating parameters and fewer protection functions. When the air conditioner leaks less than 50% of the refrigerant, the existing fluorine-deficiency logic cannot provide protection in time. Experiments have shown that when the leakag...
