How does a central air conditioner compressor works?
The central air conditioner compressor works by using an electricity to energize the motor; which it turns cause compressor crankshaft to rotates. Reciprocating compressors are a piston-cylinder type of pump. The main parts include a cylinder, piston, connecting rod, crankshaft, cylinder head and valves. The operating cycle of a reciprocating compressor is shown below. On the down stroke of the piston, a low pressure area is created between the top of the piston, the cylinder head and the suction line of the air conditioning evaporator. Cold refrigerant vapor rushes through the suction valve inlet and into the low pressure area. On the up stroke, the suction valve closes and the exhaust (discharge) valve is forced open with the increasing pressure. The vapor is compressed and forced into the discharge (high) side of the refrigeration system. When the piston reaches the top of the cylinder, the discharge valve closes, and the suction valve opens as the piston starts down again drawing i
