Hello Guys,
Recharging Tools
Recharging the air-conditioning in a vehicle correctly requires care and special tools. The main tool in this process is a recharging station, a large machine that connects to the vehicle's air-conditioning service ports and delivers the refrigerant. It also heats the refrigerant to turn it into vapor and measures the amount of refrigerant, in ounces, as it goes into the system. This machine also has gauges to monitor the system pressure. Another tool that greatly aids the recharging is an oil injector, which adds lubricating oil to the refrigerant as it is put into the air-conditioning system.
Evacuation Tool
There is only one proper way to evacuate any automotive refrigerant, and that is by using an EPA-certified evacuation or recovery machine. This machine, sometimes part of a charging station, creates a small vacuum inside the air-conditioning system and pulls all of the old refrigerant into a tank for reuse or disposal. Every type of refrigerant serviced in a shop must have its own recovery machine to prevent cross-contamination, per federal law.
Monitoring Tool
The main monitoring tools for automotive air-conditioning systems are called manifold hoses. This is a set of two hoses, one for the high-side and one for the low-side of the air-conditioning, that connect to the air-conditioning service ports of the vehicle. Each hose is attached to a pressure gauge and is used to measure the pressures in the high- and low-sides of the system. These hoses help a technician know if there is a system clog and whether the compressor is properly cycling.
Leak Detection Tools
R12 and R134a refrigerants are harmful to the atmosphere, so when a leak occurs, it is imperative to locate and properly repair it. There are two tools used to locate leaks, one being more precise than the other. A sniffer is the most basic leak detection tool. It tests the air for refrigerant and emits an audible beep that increases in pitch as the amount of refrigerant in the air becomes greater, assisting the technician in finding the source of the leak. The more precise tool is a U.V. detection kit. Refrigerant with a U.V. tinted dye is injected into the air-conditioning system, then a black light and U.V. glasses are used to locate the dye spraying from the system.
Thanks and Regards
