METER-SERVICE 7S9906 - Caterpillar

- The accumulator is a component in the air conditioning system that separates liquid refrigerants from the circuit. The accumulator is used to store a small amount of liquid refrigerant. The accumulator may also contain a desiccant which will remove moisture from the system.Ambient air - Outside airCharge - The charge is a predetermined amount of refrigerant that is put into the air conditioning system. The charge is measured in units of weight.Compressor - The compressor is a component in the system that increases the pressure of the refrigerant. The compressor increases the pressure of the refrigerant in the system by pumping.Condenser - The condenser is a component in the system where the refrigerant changes from a vapor to a liquid.Contaminants - Dirt, water, and airDesiccant - The desiccant is used in the receiver-dryer and in the accumulator. The desiccant removes moisture from the air conditioning system.Detecting - Detecting is finding the source of the problem in the system.Diaphragm - The diaphragm is a rubber-like material. The diaphragm divides the upper chamber and the lower chamber in the thermostatic expansion valve.Discharge - Discharge is the removal of some of the refrigerant or the removal of all the refrigerant from the air conditioning system.Discharge side - The discharge side is the outlet from the compressor to the condenser coil. Evacuating - Evacuating is the removal of air and moisture from the air conditioning system.Evaporation - Evaporation is the process of changing a liquid to a vapor.Evaporator - The evaporator is the component in the air conditioning system that changes the refrigerant from a liquid to a vapor. The evaporator transfers heat to the liquid refrigerant in order to convert the refrigerant into a vapor.Expansion Valve - The expansion valve is a component in the air conditioning system that regulates the flow of liquid refrigerants into the evaporator.Fluid - Fluid is a liquid or a gas.Flush - Flushing is the removal of foreign material and oil from the air conditioning system. Flush the system with a fluid that is approved. The fluid must be approved by SAE and ISO standards.Freeze - Freezing causes a liquid to become a solid.Gas - A gas is a substance that contains small particles which float in the air. A gas does not contain liquid or solid particles.Graduated Container - A graduated container is a glass container with markings on the side of the container. The markings are used in order to measure the amount of fluid in the container. The markings normally have units of ounces or units of milliliters.Heat - Thermal energyIdentifier - The identifier is an instrument that is used for testing the system. The identifier is used for determining the type of refrigerant that is in the system. The identifier is also used for determining the percentage of air that is in the system.In-line Dryer - The in-line dryer is a component in the air conditioning system that removes moisture from the system. The in-line dryer may have an air conditioner
