ATEQ is Available to Provide Consulting and Leak Testers For Automotive Air Conditioning Leak Testing Applications.

There are many components in an automotive air conditioning system such as the compressor, condenser, evaporator, accumulator and expansion valve. The refrigerant freon gas that fills the air conditioning system needs to be controlled throughout the system making sure it flows properly and does not leak out where it is not supposed to.

The A/C compressor pumps the liquid from the evaporator into a condenser and expansion valve, and then back to the evaporator. A piston compresses the air by moving up and down inside of a cylinder creating a vacuum effect that sucks in the refrigerant. These cylinders should be leak tested to make sure they do not have any manufacturing defects that could cause the refrigerant to escape.

The air conditioning condenser cools the refrigerant by passing air from the outside over a section of coils that remove the heat from the compressed gas which cools and compresses it into a liquid state. This cool liquid refrigerant flows to the evaporator in the dashboard then cools the cabin. This is where a flow quality test is important to make sure the specified range of fluid flows through the condenser.

The AC accumulator is a metal canister filled with a moisture absorbing material that filters out any debris and eliminates any moisture that may be flowing in the system. This canister should not leak out any of the moisture it is collecting. This is why the accumulator also needs to be leak tested-to keep the humidity of the air contained.

The expansion valve is located below the receiver drier with the purpose of receiving the liquid refrigerant fluid and reducing the pressure of the refrigerant fluid above the evaporator. Valves must be flow tested to make sure that the specified amount of fluid is allowed to flow through at a given time.

There are also several hoses within an air conditioning system that require leak testing. The AC hose in the evaporator transports the refrigerant through the evaporator where the freezing liquid refrigerant takes on any heat from the air blown through it and changes into a gas before returning it to the air-conditioning condenser to shed the heat.

ATEQ has developed solutions for hundreds of different automotive leak testing applications for well known OEM manufacturers over the last 40 years.  Whether you are leak testing an AC system, catheters, pacemakers, or a smartphone, ATEQ can work with you to provide efficient leak testers and develop integrated air conditioning production testing solutions.
