- 4 water quality 12
- 5 maintenance of plate type heat exchanger 12
- After cleaning has been completed make sure that the unit can be operated in a normal fashion 12
- Because the plate type heat exchanger has a structure which does not permit disassembling and cleaning follow the following proce dures for cleaning 12
- Before entering the season for use carry out the following inspections 12
- Circulate this solution for 15 20 minutes for neutral ization purpose 5 after the process of neutralization has been completed rinse the inner part of the plate type heat exchanger with care using fresh and clean water 6 when using any cleaning agent sold in the market check in advance that such agent has no corrosive features against stain less steel and copper 7 for details of cleaning method ask the manufacturer of related cleaning agent 12
- Conduct a water quality test and make sure that it is within the standard 2 clean the strainer 3 make sure that the flow rate is correct 4 make sure that the operational conditions pressure flow rate outlet temperature etc are normal 12
- English 12
- For maintenance purposes it is required to provide for a connec tion port on the water inlet and on the water outlet you must con nect a circulation pump inbetween these 2 connection ports when cleaning the plate heat exchanger with chemicals for cleaning the scale in the plate heat exchanger it is recom mended to use a solution with 5 diluted formic citric oxalic ace tic or phosphoric acid never use hydrochloric sulfuric or nitric acid because such solu tions have a strong corrosive feature 2 make sure to provide for a stopvalve in front of that inlet water pipe connection port and for a stopvalve after the outlet water pipe connection port 3 connect the piping for circulation of cleaning chemicals to the inlet and outlet piping of plate type heat exchanger fill the clean ing solution of 122 144 f for a while in the plate type heat exchanger then circulate the cleaning solution by a pump for 2 5 hours the time for cleaning depends on the temperature of cleaning solution or the degree 12
- Management of chilled water flow rate if the chilled water flow rate is not enough it will result in the freezing damage to the plate type heat exchanger check for any clogging of the strainer any air being caught any reduction in the flow rate due to failure of circulation pump by measuring the temperature and pressure differences at the inlet and outlet ports of the plate type heat exchanger if the aged difference in the temperature or pressure has increased beyond the proper range the flow rate should have decreased stop the operation and remove the cause before restart ing the operation 12
- Management of water quality the plate type heat exchanger has a structure that does not permit dismantling and cleaning or replacing any parts please pay attention carefully to the quality of water to be used for the plate type heat exchanger in order to prevent corrosion and sticking of scale the water to be used for the plate type heat exchanger should have at least the quality as specified in the table below when using any corrosion prevention agent scale depressant agent etc such agent should have no corrosive features against stainless steel and copper 12
- Notes 1 the circle marks in the columns for corrosion or scale to develop 2 corrosion has a tendency to occur when water temperature is high 104 f or more and if metals with no protective coating whatever are directly exposed to water it would be a good idea to take effec tive measures against corrosion such as adding a corrosion inhibitor or deaeration treatment 3 in a condenser water circuit that uses a closed cooling tower the closed circuit circulating water and make up water must satisfy its water quality standards for the hot water system and passing water and make up water must satisfy those for the circulation type cooling water system 4 the supply water must be clean tap water industrial water or clean underground water do not use purified or softened water 5 the fifteen items in the table above represent typical causes of cor rosion and scale 6 once through water may cause corrosion do not use once through water 12
- Steps to be taken when a freezing protection device was activated when the freezing protection device should be activated during operation remove the cause without fail before restarting the opera tion if the freezing protection device has been once activated a par tial freezing has occurred if you restart the operation without removing the cause the plate type heat exchanger will be closed and the ice cannot be melted and in addition the freezing process will be repeated resulting in any damage to the plate type heat exchanger leading to any such accidents that the refrigerant starts leaking or water starts entering the refrigerant circuit 12
- The performance of a plate type heat exchanger may decline due to scale accumulation it may be damaged by freezing due to the drop of flow rate for this reason it is necessary to carry out programmed main tenances at a regular interval in order to prevent the scale from being generated 12
