1. JoyeJode 3 45 Principal of Cascade Refrigeration System The cascade refrigeration system is designed to use different refrigerants which have different boiling points in one system in order to reach ultra low temperatures 60 down to 150 range Therefore a cascade cooling system needs two sepeate cooling systems compressors Each cooling system compressor works simultaneously The first stage Compressor exists to condense the high pressure line of the second stage compressor The second stage comprressor is the main system which maintains the ultra low temperature of the freezer The refrigerant of the first stage compressor is compressed This compressed refrigerant is cooled by the air cooled condenser The condensed refrigerant is dried by a drier The dried refrigerant evaporates in the evaporator by a capillary tube low pressure low temperature The heat exchanger is cooled down to less than 40 C This heat exchanger is now used to condensate the compressed refrigerant coming from the second stage compressor The strainer removes dirt from the evaporated refrigerant Because we use a liquid separator liquid refrigerant is prevented from sucking into the compressor The second stage refrigerant is compressed in the second stage compressor The compressed refrigerant is pre cooled by passing through a pre cooler After passing the oil separator and drier it is condensed in the heat exchanger cooled to 40 C by2. Volt free contacts The main power switch is located at the back of the freezer After power supply is checked and the unit is earthed open de condenser door By switching the main power switch in ON position the Freezer will use the power and on this time is ready for operation If the freezer is not in use please put the main switch in OFF position 44 Door Alarm The door alarm can be used in combination with the CO2 backup system It is a safety feature to make sure the operator does not get into contact with liquid CO2 LN2 in case of opening the door of the freezer Always connect the LN2 backup system to the door alarm connection at the back of the freezer For safety measure resistance on the contacts with Ohm metre 1 Do contact 1 amp 2 show resistance Connection should be a closed loop normal conditions closed loop door open conditions open loop 2 Open door lid 3 Do contact 1 amp 2 show unlimited resistance Connection should be a open loop 4 5 Remote Alarm The remote alarm is a volt free dry contact which will alarm in case of 1 High temperature alarm 2 Low temperature alarm 3 Power failure Male and female 4 Clean filter alarm alarm plug 1019 COM NO COM NO NC NC Alarm Conditions Normal Conditions In normal conditions relay is always closed which means connection between COM and NC normally closed In case of alarm relay is open and means connection between COM and NO
