PURPOSE: A noiseless air compressor is provided to eliminate noise by resolving frictional heat. CONSTITUTION: A compressor(11) comprises a case(1) having a low pressure port(1A) formed on one side thereof to introduce refrigerant and a high pressure port(1B) formed on the other side thereof to discharge compressed refrigerant; lubricant(2) placed in a lower part in the case for cooling; an electromotor(3) installed on the lower part in the case, and rotating at low speed; a crankshaft(4) having one side fixed on a rotary axis of the electromotor and the other side installed on a connecting rod(7) to rotate, and receiving driving force of the electromotor to linearly reciprocate a piston(6) in a cylindrical body(5A); a cylinder(5) joined to an upper part of the case; the piston inserted into the cylinder to reciprocate left and right; the connecting rod having one side installed to the piston through a fixing pin to rotate and the other side installed to the crankshaft; a connecting pipe(8) transporting air introduced through the low pressure port, and compressed in the cylinder to the high pressure port; and an exhaust fan installed on an upper end of a cover installed on an outer upper part of the case to discharge heat generated in the compressor.
