Sensor mounting box, air conditioner leak detecting device and sensor

Abstract

The invention discloses a sensor mounting box, an air conditioner leak detecting device and a sensor. The sensor mounting box comprises a box body. A sensor mounting base is arranged in the box body. A signal wire, a power supply wire and a ground wire or a null line are connected to the box body. The sensor arranged in the sensor mounting base is connected to the signal wire, the power supply wire and the ground wire or the null line correspondingly. According to the sensor mounting box, for an air conditioner with the leak detecting sensor which needs to be replaced at regular intervals, only the leak detecting sensor needs to be detached from the sensor mounting box, other parts do not need to be detached, the detaching steps of the leak detecting sensor can be reduced, a detaching process is simplified, and manpower cost is lowered.

Description

technical field [0001] The invention relates to an air conditioner detection device, in particular to a sensor installation box for flammable refrigerant of the air conditioner, an air conditioner leak detection device and the air conditioner. Background technique [0002] In order to protect the human living environment and reduce the damage to the ozone layer of the atmosphere and the greenhouse effect, in recent years, people have begun to replace hydrocarbons and HFC refrigerants with new refrigerants. However, most of these refrigerants are easy to burn and explode. Leakage means that there is a danger of explosion. Therefore, it is particularly important to use flammable refrigerants safely and reliably in air-conditioning systems. Certain safety and explosion-proof measures must be taken, such as installing a leak detection device for flammable refrigerants in air conditioners. [0003] However, the service time of the leak detection sensor has certain requirements, a...

[0002] In order to protect the human living environment and reduce the damage to the ozone layer of the atmosphere and the greenhouse effect, in recent years, people have begun to replace hydrocarbons and HFC refrigerants with new refrigerants. However, most of these refrigerants are easy to burn and explode. Therefore, it is particularly important to use flammable refrigerants safely and reliably in air-conditioning systems, and certain safety and explosion-proof measures must be taken, such as installing a leak detection device for flammable refrigerants in air conditioners

[0003] However, the service time of the leak detection sensor has certain requirements, and there is a possibility of failure. Therefore, the leak detection sensor needs to be replaced regularly or irregularly.

It is more complicated to replace the leak detection sensor in the existing air conditioner. Usually, the connecting wires on the main board in the electrical box, including power wires, signal wires, ground wires or neutral wires, and the entire leak detection sensor must be disassembled first, and then reinstalled. , the process is cumbersome, and it may even cause leakage in other places such as the small elbow of the evaporator during the disassembly process
