Components of the air-conditioning system, their organization and check

• Oil coolants
• Compressor
• Condenser
• Receiver-dehydrator
• Expansion valve
• Evaporator
• Accumulator
• Expansion tube

Organization and principle of action

The accumulator is installed between a line of release of the evaporator and the compressor. Receiving from the evaporator in a liquid and gaseous condition and oil, a gaseous refrigerant sends the mixed refrigerant of low pressure to the compressor directly, and a liquid refrigerant to the compressor after evaporation from heating by environmental heat. And oil comes back to the compressor through pouring hole of oil. In the bottom part of the accumulator there are sealed drier which performs work on removal of a moisture and various impurity in system.

1 – Inlet 2 – Outlet 3 – Service valve (from the low pressure side)

1 – Outlet 2 – Refrigerant Vapor 3 – Inlet 4 – Baffle 5 – Internl Tube 6 – Desiccai Bag 7 – Filter 8 – Оil Bleed Hole

Checking

There are cases of occurrence of malfunctions of the accumulator because of internal corking. They check pressure through installing a manometer in the service auxiliary valve of low pressure located on the top part of the accumulator.

As the drier of the accumulator has good absorbing abilities, it is necessary to pay attention to the following safety measures.

For protection from contact to an atmosphere it is good to close target and entrance apertures.

At installation of the conditioner after connection of other pipelines, to attach up to air exhaust and to put after a detachment, to close immediately.

Not to mix entrance and an exhaust outlet.

Replacement needs to be made necessarily in gathering.
