8. Set the distillate pump control switch to the AUTO mode. 9. Check the plant operation parameters maintaining their values within the rated value range.

Provisions Cooling Procedure for Starting the Plant in Manual Mode 1. Turn on the sea water pump. Monitor its operation by the pressure gauge. 2. Set the compressor operating mode switch to MANUAL position. 3. Open the shut-off valves on the liquid refrigerant circulation lines. 4. If the refrigeration plant is expected to operate for its own group of storerooms only, shut-off valves on the connecting steam and liquid pipelines are closed. If one of the refrigeration plants operates for both groups of consumers (the second plant is not turned on), the shut-off valves should be closed. 5. Adjust the low pressure switch. On “OFF” scale, set the pressure value whereby the compressor is turned off. By the moment of the compressor stop, the temperature in all the cooled storerooms should achieve the set value. On “ON” scale, set the pressure value whereby the compressor is turned on. By this moment, temperature in at least one room has grown to more than the set value. 6. Adjust thermoswitches for each storeroom. 7. For “Butter” and “Dry. Prov.” storerooms. Adjust the evaporation pressure control.

8. Open the master solenoid valve. 9. Start the compressor. 10. Set the operating mode switch of the equipment defrosting system to AUTO position. 11. Set the time interval (in hours) at which the defrosting of refrigeration equipment will be performed in each cooling space. 12. Set the defrosting system control switch to AUTO position. 13. Monitor the plant operation parameters maintaining their values within the standard range. You will be advised about all the faults by the alarm system. As a monitored parameter reaches the maximum permissible value, the safety system is actuated: an appropriate alarm is turned on in the bottom part of the screen. 14. Load (unload) as necessary the set mass of goods (products) into/from the storerooms. Defrosting of Refrigeration Equipment in Manual Mode This is used in case of excessive growth of hoar frost on the surface of refrigerating units: 1. If the thickness of the hoar frost layer is 5 mm or more, and the equipment defrosting process has not been started automatically, then it is necessary to: Set the defrosting system control switch to MANUAL position. 2. Press “ON” button under the switch.


Replenishment of Liquid Refrigerant This is performed if the refrigerating plant operating mode indicates the insufficiency of liquid refrigerant in the system (low level of liquid refrigerant in the condenser receiver part, gas bubbles in the sight glass, low suction pressure, extensive overheating on the suction line and high charging temperature): 1. Set the compressor operating mode switch to MANUAL position. 2. Close the shut-off valve on the liquid line after the condenser. 3. Open the make-up valve. 4.

After the suction pressure (in the sump) has dropped to a value below the atmospheric pressure (Ε -0.5 bars), stop the compressor. 4. Open the oil make-up valve. 5. After the end of the process (oil level is not higher than 2/3 of the sight glass), close the valve. 6. Turn the compressor on. 7. Set the operating mode switch to AUTO position. 8. Monitor the refrigerating plant operating parameters. Where the compressor cannot be stopped (e.g. loading of a considerable amount of goods with rather high temperature) at the moment of oil replenishment, it is necessary: 9. To re-adjust the low pressure switch – on “OFF” scale make Η -0.5 – -0.3 setting. 10. After the pressure has dropped below the atmospheric pressure, open the oil make-up valve. 11. After the end of the process, close the valve. 12. Re-adjust the low pressure switch to the operating mode. 13. Monitor the refrigerating plant operating parameters. If oil is added to the operating compressor, the replenishment will be either excessive or incomplete.

Set the compressor operating mode switch to MANUAL position. 2. Turn the compressor off. 3. Turn the compressor off (on the right in Fig). 4. After the water temperature drops at the condenser outlet (OUTLET temperature gauge) down to the sea water temperature (INLET temperature gauge), open the valve for the discharge of air from the system. 5. As the charging pressure drops to the value corresponding to the optimum condensation temperature, i.e. as the temperature readings in DISCHARGE pressure gauge and DISCHARGE temperature gauge are equalised, close the air discharge valve. 6. Monitor the level of liquid refrigerant by using the sight glass on the condenser (there should be no lowering of the level). 7. Adjust the condensation pressure control for the maintaining of the set pressure value (0.6 – 0.7 MPa). 8. Turn the compressor on. 9. Set the operating mode switch to AUTO position. Replacement of Filter Drain This is done when the colour of the sight glass indicator changes. The indicator

colour changes from green to yellow as the moisture penetrates in the liquid refrigerant system: 1. Close the shut-off valves of the filter drain. 2. Open the bypass valve of the filter drain. As this is done, the indicator colour will change from the yellow colour to green, i.e. there will be an imitation of the filter drain replacement. 3. Open the shut-off valves of the filter drain. 4. Close the bypass valves of the filter drain. Compressor Breakdown In case of failure of one of the compressors, the other compressor will maintain the required temperature in all the six provision storerooms: 1.

Open the shut-off valves on the liquid refrigerant circulation lines. 5. Adjust temperature switches. 6. Set the compressors operating mode switch to MANUAL position. Simulator Module Systems 7. Adjust the low pressure switch. On “OFF” scale, set the suction pressure value whereupon, with some delay, the compressor cylinders will start to turn off. On “ON” scale, set the pressure value whereupon the compressor cylinders will start to turn on, by the timer, too. 8. Open the master solenoid valve. 9. Check if the compressor suction valve is closed. 10. Run the compressor.

As this is done, the electromagnetic actuators which raise the suction valve plates are ON, taking the cylinders out of operation and thus creating the compressor’s idle running. After the compressor has been run, the pushing devices are turned off in several seconds, and its cylinders start operating: 1. Partly open (to 5-10%) the compressor suction valve. 2. Check pressure in the compressor lubricating system. 3. With normal oil pressure value, continue opening the suction valve observing safety precautions. 4. Set the compressor operating mode switch to AUTO position. Simulator Module Systems 5. Use manual switches to set the desired air temperature in the cabins. 6. Use manual switches to set the desired air temperature in the cabins. Values of temperature and humidity in the cabin are shown on indicators. 7. Monitor the plant operating parameters maintaining their values within a standard range. The alarm system will signal about all the possible faults. As a monitored parameters reaches its limit value, and appropriate alarm lights up in the bottom part of the screen. Where no steps are made to normalise the compressor operation, SHUT DOWN protection is actuated, and the compressor is stopped, where after it can be brought back into operation in MANUAL mode only. Procedure to Bring the Air Conditioning System into Operation in Transient Mode The air conditioning system is switched to the transient mode at the ambient temperature of +15°С to +25°С.


Set the conditioner operating mode switch to WINTER position, turn off the heaters and humidifier: the fan only will remain operating. Procedure to Bring the Air Conditioning System into Operation in Winter Mode The air conditioning system is switched to the winter operating mode when the ambient temperature drops to +15°С: 1. Set the conditioner operating mode switch to WINTER position. 2. Depending on the ambient temperature (tн), tune on the first and second stage heaters. Ambient temperature after the first and second stage heaters, as well as relative humidity of the treated air is maintained automatically by using the direct-acting temperature controls (steam control valves). In this case, the first stage control maintains constant temperature at the first duct outlet, whereas the second stage control maintains temperature at the second duct outlet in accordance with its setting changed automatically with the ambient temperature. Simulator Module Systems 3. To control the air humidity, it is first necessary to turn on “H2O” valve manually monitoring the air humidity values in the first and second ducts. After it has been set, humidity is controlled automatically in accordance with the ambient temperature by the first duct temperature control. 4. Use manual switches in the cabin to set the desired temperature in the cabin. 5. Monitor the air conditioned operation parameters maintaining their values within the standard range.

Refrigerant Replenishment The operation is performed if the refrigeration plant operating mode indicates insufficient refrigerant in the system (low refrigerant level in the receiver, gas bubbles in the sight glass, low suction pressure, excessive heating in the suction line and high temperature on the charging line): 1.

Adjust the condensation pressure control for the maintaining of the set pressure value (9-10 bars). 9. Turn the compressor on. 10. Open the compressor suction valve. 11. Set the operating mode switch to AUTO position. Simulator Module Systems Replacement if Moisture Eliminator This is done when the colour of the sight glass indicator changes. The indicator colour changes from green to yellow as the moisture penetrates in the refrigerant system: 1. Close the moisture eliminator shut-off valves. 2. Open the moisture eliminator bypass valve. 3. Open the valve for drawing off refrigerant from the moisture eliminator for several minutes (1-2 minutes). 4. Close the valve for drawing off refrigerant from the moisture eliminator. 5. Open the moisture eliminator shut-off valves. 6. Close the moisture eliminator bypass valve. As this is done, the indicator colour will change from the yellow colour to green, i.e. there will be an imitation of the moisture eliminator replacement.


Elimination of Compressor Damp Operation This is performed if there is a sharp drop of temperature on the charging line (down to +10-0°С), overheating decreases, the compressor noise changes to dull, the cylinder walls and sump are covered with ice (if there is considerable flooding with liquid refrigerant), rattling noise appears, and the amperemeter needle goes beyond the red line: 1. Close the compressor suction valve leaving it 5-10% open. 2. After the indications of damp operation disappear, open the compressor suction valve slowly. 3. Check oil level in the sump replenish the compressor with oil as required. Breakage of Conditioner Fan If a fan is broken, air is supplied to this conditioner by the fan of the conditioner on the other board through the air flap. To do this, press the air flap control button. You can act in much the same way in case of the fan air filter fouling until it is “replaced” (the fault is eliminated from the instructor workplace). Breakage of Automatic Steam Control Valve If the automatic steam control valve is broken: 1. Close the shut-off valves “Bypass 1” and “Bypass 2” of the steam control (for the time of the repairs). 2. Open the manual control valve on the bypass line, adjusting its flow by the

readings of temperature gauges at the outlets of the first and second ducts.
