- The accumulator is a component of an air conditioning system with an orifice tube. The accumulator is located between the evaporator coil and the compressor. The accumulator's function is to separate liquid refrigerant and oil from the refrigerant that is mostly vaporized. Removing the liquid refrigerant and removing the oil protects the compressor from liquid slugging. Some air conditioning systems have an accumulator that contains a desiccant. The desiccant 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 will cause the refrigerant to flow through the system.Condenser - The condenser is a component in the system that changes the refrigerant from a high pressure, high temperature vapor to a high pressure, high temperature liquid.Contaminants - Dirt, water, and airDesiccant - The desiccant is used in the receiver-dryer or 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 Side - The discharge side of an air conditioning system is the outlet from the compressor to the outlet of the condenser coil. The discharge side is also referred to as the high side of an air conditioning system.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. You must flush the system with fluid that is approved. The fluid must be approved by SAE. The fluid must be approved by ISO.Foaming - Foam that can be seen in the sight glass is an indication of low refrigerant level in the system.Freeze - Freezing causes a liquid to become a solid.Frost - Frost may be caused by a blockage somewhere in the system.Gas - A gas is a substance that contains very 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
