Water Cooled Package Air Conditioner, also called Water Source heat pump, is a self-contained packaged air conditioners with Water Cooled Condenser. In these packaged air conditions the condenser is cooled by the water. The condenser is shell and tube type or coaxial type, with refrigerant flowing along the tube side and the cooling water flowing along the shell side. The water has to be supplied continuously in these systems to maintain functioning of the air conditioning system.
STRUCTURE OF WATER COOLED PACKAGE UNIT
All the components of this package AC are assembled at the factory site. The gas charging is also done at the factory thus one does not have to perform the complicated operations of the laying the piping, evacuation, gas charging, and leak testing at the site. The unit can be transported very easily to the site and is installed easily on the plane surface. Since all the components are assembled at the factory, the high quality of the packaged unit is ensured.
INSTALLATION OF WATER COOLED PACKAGE
Since water cooled package unit uses water to cool the condenser, so there are two typical installation methods of water cooled package units. One is called water source which is connected to a cooling tower, another is called ground source which is connected to ground water.
When the water cooled package units are used for air conditioning of big building, the installation can be easily divided partially to several phases, reference below picture for an example. First to install cooling tower and main water pipes, and then connect all water cooled package units to its main water pipes phase by phase. So as to save the initial investments.
