III-321OUTDOOR UNITS2-10. Cycle function parts1) RVXMHF040/050/060✴✴2) Description of cycle function partsNo Cycle parts Functions1 Digital scroll compressor Digital scroll compressor controls the capacities 10 to 100% of its capacity.2 PWM solenoid valve It is used for variation of Digital compressor's capacity. When the valve is opened, Digital scrollcompressor keeps the unloading state, otherwise loading state.3 Hot gas bypass solenoid valve When the suction pressure becomes abnormally low in pressure, it opens.4 Liquid bypass solenoid valve When the compressor is overheated, it opens to make the discharge temperature low.5 Reversing solenoid valve (4 way valve) It enables to change operating model, cooling and heating mode.6 Check valve It enables to bypass the refrigerant when cooling operation.7 EEV It controls the amount of refrigerant entering outdoor's heat exchanger in heating operation.8 Discharge temperature sensor It measures the temperature of compressor outlet. The main function of it is to protectcompressor from overheating.9 Cond_out temperature sensor It measures the temperature of condenser outlet.10 Ambient air temperature sensor It measures the temperature of ambient.11 Sump temperature sensor With checking sump temperature of compressor, it prevents the compressor from liquid backand overheating.12 Receiver tank It accumulates the liquidized refrigerant and also separates liquid and gas.13 Accumulator It prevents the compressor from liquid back.14 Muffler It reduces the noise and vibration of discharged gas from the compressor.15 Condenser It enables to exchange the heat.16 High pressure switch It protects the system from unusually high in pressure.17 Low pressure switch It protects the system from unusually low in pressure.Ambient air temp. sensor3-2.mini_Outdoor unit(294~321) 3/15/08 4:06 Page 321
