Problems solved by technology

[0021] Therefore, in the existing refrigerant leakage detection device of the air conditioner, only the temperature change corresponding to the amount of refrigerant at the output end of the indoor heat exchanger piping is detected, and the leakage of the refrigerant is judged to immediately stop the load (compressor, outdoor fan) drive, and the unbalanced refrigerant cycle will lead to compressor damage

Abstract

The invention relates to a detector and a method for detecting the air condition cooling medium leakage. The detector comprises the following parts: a key input part used to input the user order, an indoor pipe temperature detecting part used to quote the insufficient condition of the cooling medium value by the temperature change and the frequency of the indoor heat transformer and controls the compressor and the driver outside the fan, a display part used to control the controlling signal and display weather the cooling medium value leakage is measured.

Description

technical field [0001] The invention relates to a refrigerant leakage detection device of an air conditioner and a method thereof. Background technique [0002] In general, an air conditioner is a home appliance that keeps the air in the room in the most suitable state according to its use and purpose. For example, in summer, the cooling operation is used to keep the indoor cool, and in winter, the heating operation is used to keep the indoor warm. Moreover, the air conditioner regulates the indoor humidity, thereby regulating the indoor air to maintain a fresh state. [0003] As a result, air conditioners and other products that facilitate family life have been gradually popularized, and users demand products with higher efficiency, better performance, and ease of use. [0004] The above-mentioned air conditioners include: split-type air conditioners in which the indoor unit and outdoor unit are separated; integrated air conditioners in which the indoor unit and outdoor u...
