CONDENSER The condenser is a heat exchanger used to cool the hot vaporised refrigerant. Also the refrigerant changes its state from vapour to liquid. The condenser is placed behind the radiator. Cooling fan is placed behind the condenser to pull ambient air through radiator and condenser. CONDENSER SEALING DUCTS Sealing’s are used to guide the flow of the air to the condenser and also to avoid the hot air recirculating from the bonnet compartment to the condenser. RECEIVER DRIER (R.D) The receiver drier is integrated into the Condenser and has three main functions. 1. It absorbs the moisture in the refrigerant. 2. It allows only liquid (high pressure liquid) to pass through to the TXV. 3.It keeps a reserve of refrigerant to accommodate fluctuating refrigerant requirements. D. SOLAR LOAD SENSOR Solar load sensor is a photodiode that measures the relative solar load. It provides the output current proportional to solar heating. LOCATION It is fitted on front defrost grill. INSPECTION Fit the solar load sensor into its adaptor. Connect the electrical connection. Measure response at different intensity and plot graph of sensor output and intensity. The plotted graph should approximately match with following graph. FATC 27
