HVAC 24 RECEIVER DRIER (R.D) ,W¶V D VWRUDJH GHYLFH IRU OLTXLG UHIULJHUDQW and has three main functions. i) It absorbs the moisture in the refrigerant. ii) It allows only liquid ( high pressure liquid) to pass through to the TXV. iii) It keeps a reserve of refrigerant to accommodate fluctuating refrigerant requirements. 10.1.5.6 THERMISTER OR THERMO SENSOR NOTE To remove thermister from the HVAC unit, the HVAC assembly needs to be dismantled. It is a temperature sensing device, which is posi- tioned at the coldest point of the evaporator (as shown in the fig below) . The control unit switches OFF the compressor at a temperature when con- densed water tends to form ice on the fins of evaporator. Thus it maintains the evaporator tem- perature within a specified range. THERMISTER POSITION ON EVAPORATOR The thermister bulb should be fixed such that the sensing bulb is right over the point as shown figure above. ! CAUTION The point indicated above is the location of the sens- ing bulb and not the point where clip has to be inserted. Any minor change in position of the evapo- rator can lead to malfunctioning of the HVAC system. PIN OUT CONNECTION DETAILS PIN NUMBER CONNECTION 1 Sensor +ve 2 Sensor -ve NOTE
