Patent ID: 7062938

Claim:
A condensing system in a cooling system comprising: an air cooling condenser including a folded serpentine heat transfer pipe for enabling cooling of high temperature and pressure from a compressor to flow therethrough, a number of fins mounted on the heat transfer pipe and a condenser fan installed in the front of the air cooling condenser so that the ambient air forcibly introduced by the condenser fan is guided by the fins to have heat exchange with coolant flowing through the heat transfer pipe; and a water cooling condenser disposed between the air cooling condenser and the compressor in the cooling system, wherein the water cooling condenser includes: a coolant pipe disposed between the compressor and the air cooling condenser, a water passage for enabling water to flow therethrough to have heat exchange with coolant in the coolant pipe, an inlet pipe and an outlet pipe connected with the water passage of the water cooling condenser for automatically feeding and discharging water in a direction reverse to a flowing direction of coolant, and a control valve installed at the inlet side of the inlet pipe for automatically controlling water feed to the water passage according to ambient air temperature, coolant pressure and condensing load.
