Experiment and simulation analysis of air-cooled condenser and water-cooled condenser series systems

Dry blub temperature has a great impact on heat removal effect of air-cooled condenser. High dry blub temperature leads to high condensing temperature, and compressor capacity needs to be expanded to achieve the same cooling capacity, which will decrease performance of the refrigerating system. For the air-cooled air conditioning system in a communication room, proposes the scheme of adding a water-cooled condenser to the system to work together with the air-cooled condenser. Simulates, tests and compares the air-cooled first pattern with the water-cooled first pattern, and analyses the determination of suitable heat exchange area of water-cooled condenser for the given heat exchange area of the air-cooled condenser. The result shows that the air-cooled first pattern is superior to the water-cooled first pattern.
