See to it that no random adjustment be made on the set points on site. 1) Total leakage of refrigerant. cleaning time and temperature according to the scale settlement condition. Replacing parts Parts to be replaced should be the ones provided by our company. Air tight test must be made if there is a leakage or parts of refrigerating system is to be replaced. leakage detection must be made on the pressurized nitrogen used for the system. But in no way should cleaning agent containing chlorine acid or fluoride should be used as the water-side heat exchange is made from stainless steel and is easy to be eroded to cause refrigerant leakage. and take timely measures if necessary. 4) Fix connections of all wires. 2) Clean water pipe system. Pay attention to the following aspects during the cleaning and scale-removing process: ● Water-side heat exchanger should be done be professionals. Removing scale After long-time operation. Ineffective and unreliable elements should be replaced in time. skins and nasal mucosa. Contact relevant company for treating the treated waste liquid. and whether there is bad contact at the contact point caused by oxidation and debris etc. ● Check the reliability of the electric elements in time. If repair welding is needed. gloves. current and phase balance. mask and shoes) must be used during the cleaning process to avoid breathing in or contacting the agent as the cleaning agent and neutralization agent is corrosive to eyes. calcium oxide or other minerals will be settled in the heat transfer surface of the water-side heat exchanger. 5) It is a must to electrify the machine before startup. the surface of the unit outside and inside should be cleaned and dried. Find out reasons and eliminate the failure if abnormality is found.. adjust the density of the agent. Frequently check the work voltage.R410A air-cooled modular chiller unit 50Hz MCAC-ATSM-2012-10 14 Maintenance Maintenance for main components： ● Close attention should be paid to the discharge and suction pressure during the running process. Take different measures in the following two different conditions from refrigerant injection. Winter shutdown For shutdown in winter. ● Clean the pipe and heat exchanger with clean water after cleaning agent is used. Open discharge water valve to discharge the stored water in the clean water system to prevent freezing accident (it is preferable to inject antifreeze in the pipe). ● Regularly check whether the electric connection is loose. These substances will affect the heat transfer performance when there is too much scale in the heat transfer surface and sequentially cause that electricity consumption increases and the discharge pressure is too high (or suction pressure too low). neutralization treatment needs to be done on the waste liquid. ● Protection equipment (such as goggles. ● Control and protect the equipment. ● In case of using cleaning agent. Conduct water treatment to prevent water system from being eroded or re-absorption of scale. First startup after shutdown The following preparations should be made for re-startup of unit after long-time shutdown: 1) Thoroughly check and clean the unit. Organic acids such as formic acid. Refrigeration system Determine whether refrigerant is needed by checking the value of suction and discharge pressure and check whether there is a leakage. control valve and other equipment of water pipe system. 3) Check pump. ● After pickling is completed. In case of such situation. citric acid and acetic acid may be used to clean the scale. Never replace any part with different part. Please refer to relevant professionals for the power of auxiliary electric heater. 3) Remove suction and discharge pipes of compressor. ● Remove air from the system pipe with vacuum pump. Auxiliary electric heater When the ambient temperature is lower than 2℃.4Mpa. therefore. Appropriate amount of refrigerant for injection has been indicated on the nameplate and the table of main technical parameters. 2) Water pipe may be frozen when the chilled water flow switch and anti-freezing temperature senor become ineffective at running. 1) If the unit that is shut down for standby is placed in an environment where the outdoor temperature is lower than 0℃. so attention must be paid to anti-freezing. This damage of frost crack is not within the warranty scope. the user may consider to use auxiliary electric heater. the water in the water system should be drained. ● Connect vacuum pumping pipe at the fluoride nozzle at low-pressure side. Before injecting refrigerant. inject refrigerant into the refrigeration system with refrigerant bottle. the whole refrigeration system must be completely dry and of vacuum pumping. Refrigerant must be injected from the low pressure side of system. Connect refrigerant injection bottle on the fluoride nozzle at low-pressure side and connect pressure gauge at low pressure side. and make the low pressure control switch short circuit if necessary. severe damage may be caused. Confirm that the indication pressure in dial gauge is within the specified scope. The vacuum pumping lasts for above 3 hours. System anti-freezing In case of freezing at the water-side heat exchanger interval channel. the heating efficiency decreases with the decline of the outdoor temperature. 163 . heat exchange may be broken and appears leakage. ● Make chilled water circulate and start up unit. If the required amount has not been reached but no more injection can be done. In order to make the air-cooled heat pump stably run in a relatively cold region and supplement some heat lost due to de-frosting. ● The injection amount of refrigerant will be affected by the ambient temperature. 2) Remove power source connection wire of compressor. ● Slowly inject refrigerant into the system and check suction and discharge pressure. 3) Frost crack may happen to water-side heat exchanger at maintenance when refrigerant is injected to the unit or is discharged for repair. Pipe freezing is likely to happen any time when the pressure of refrigerant is below 0. 5) Move the compressor. i. 4) Remove fastening screw of compressor.e. make the chilled water circulate and start up the unit for injection. 2) Refrigerant supplement. the water in the heat exchanger must be kept flowing or be thoroughly discharged. When the lowest ambient temperature in the user‟s region in winter is within 0℃~10℃.MCAC-ATSM-2012-10 R410A air-cooled modular chiller unit 50Hz system is discharged. When the degree of vacuum is reached. Therefore. the water flow switch must be connected in accordance with the connection diagram. Make the low pressure switch temporarily short circuit if necessary.
