A vehicle-mounted air-conditioning refrigeration fault monitoring device based on internal and external temperature difference detection

Abstract

The invention discloses vehicle-mounted air conditioner refrigeration fault monitoring equipment based on internal and external temperature difference detection. The vehicle-mounted air conditioner refrigeration fault monitoring equipment based on internal and external temperature difference detection structurally comprises an outer steam cover, a temperature raising control device and a warning lamp device. The outer steam cover is provided with a water pipe, a glass cover and a liquid interlayer. The temperature raising control device is provided with a heating box and a water tank. The warning lamp device is provided with a control power supply box, a first sponge rod, a second sponge rod and a warning lamp. The vehicle-mounted air conditioner refrigeration fault monitoring equipment based on internal and external temperature difference detection has the beneficial effects that the internal temperature and external temperature of the glass cover can be adjusted so as to control theamount of water drops formed by water vapor and to further control the connection of a warning lamp circuit. By means of the method, fog on the glass cover can be seen by naked eyes, and whether the warning lamp is turned on or not can also be observed, so that whether the vehicle-mounted air conditioner refrigeration fault monitoring equipment runs normally or not can be judged.

Description

technical field [0001] The invention relates to the field of monitoring equipment, in particular to a vehicle-mounted air-conditioning refrigeration failure monitoring equipment based on detection of internal and external temperature differences. Background technique [0002] Cars can be seen everywhere in daily life, and have even become the main means of transportation for people's daily travel. The massive development of the market has made the needs of the automotive industry widely needed. Therefore, the internal configuration of cars is also increasing. In addition to the basic configuration, the car Air-conditioning and refrigeration equipment is particularly important, especially the heat and gas generated during driving will cause the temperature inside the car to rise and the harmful substances in the air to increase. Therefore, refrigeration devices are required to ventilate and cool down. a very important proportion. [0003] Aiming at the current vehicle-mounte...

AI Technical Summary

Problems solved by technology

[0004] Generally speaking, if any part or configuration on the car is broken, it usually only needs to be sent for repair, but when the car air-conditioning and refrigeration equipment breaks down, it is difficult for us to detect whether it is really broken. Whether it is lowered or not, it is difficult to judge accurately by the human body alone, so a device that can detect whether the vehicle-mounted air-conditioning and refrigeration equipment is out of order is needed
