Embodiment Construction
[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.
[0040] An air-conditioning refrigerant leakage alarm device of the present invention alarms the leakage of air-conditioning refrigerant by detecting the change of pressure in the interlayer cavity of the air-conditioning pipeline, including: an air-conditioning pipeline 100 , a pressure detector 300 , and an alarm 500 .
[0041] figure 1 It is a schematic diagram of an air-conditioning pipeline in the prior art, Figure 4 The schematic diagram of the air-conditioning pipeline provided by the present invention, through figure 1 and Figure 4 It can be seen that the air-conditioning duct 100 of the present invention is a double-layer structure including an inner tube 101 and an outer tube 102 . In other embodiments, the outer tube 102 may be sheathed...

The invention discloses a leak alarm device of a refrigerator of an air conditioner, and relates to an anti-leak technology of the refrigerator of the air conditioner. The leak alarm device of the refrigerator of the air conditioner comprises an air conditioner pipeline, a pressure detector and an alarm, wherein the air conditioner pipeline comprises an inner layer of a pipe and an outer layer of a pipeline, an interlayer cavity is formed between the two layers of the pipes, and the pressure in the interlayer cavity is greater than that of outside of the outer layer of the pipe and is smaller than the pressure in the inner layer of the pipe; the pressure detector is connected to the interlayer cavity and is used for detecting the pressure change of the interlayer cavity; when the pressure of the interlayer cavity is increased to an upper limit of a predetermined pressure interval, an alarm signal 1 that represents large pressure is output, when the pressure of the interlayer cavity is reduced to a lower limit of the predetermined pressure interval, an alarm signal 2 that represents small pressure is output. The refrigerator is circulated in the inner layer of the pipe and the inner layer of the pipe is covered with the outer layer of the pipe so as to prevent leakage of the refrigerator of the air conditioner due to rupture of the inner layer of the pipe; the pressure between the outer layer of the pipe and the inner layer of the pipe is detected to judge whether the refrigerator of the air conditioner has leak, and the corresponding alarm is output.
Description
technical field [0001] The invention relates to air-conditioning refrigerant leakage prevention technology, in particular to an air-conditioning refrigerant leakage alarm device. Background technique [0002] Freon is the main refrigerant for air conditioners. Leakage of air conditioner refrigerants will affect the cooling effect of the vehicle, and Freon is poisonous to the human body and will damage the atmosphere. Therefore, the tightness of the air conditioner pipeline is directly related to the working efficiency and protection of the environment. [0003] In order to solve the problem of air-conditioning refrigerant leakage, Chinese patent CN2573919Y discloses a patent titled "Air Conditioning Refrigerant Leakage Prevention Device". The cone nut is screwed on the valve body, and it also includes spacers, reinforcement rings, flat washers and cone washers. There are spacers, reinforcement rings and flat washers between the inner cavity of the nut cover and the end face...
