How to install the air-cooled condensing unit: Simple instructions -F.Sanzo-
The installation of air-cooled condensing unit , although simple, requires some precautions. The condensing unit requires correct positioning for a good ventilation which avoids the recirculation of air which can cause condensation problems. Furthermore, the correct sizing of the liquid and suction pipes is important for the proper functioning of the system. It is important to avoid the backflow of lubricant and liquid refrigerant to the compressor when the condensing unit stops. It is necessary to provide suitable siphons at the base of each vertical section with an upward direction of the flow; if the discharge line is of high vertical development which connects the compressor to the remote condenser, that is installed at a higher altitude, it must be equipped with an adequate number of siphons. Even the suction line, the pipe that connects the evaporator to the compressor suction, must meet certain requirements such as: • favor the return of oil to th...
