- 5 maintenance of plate type heat exchanger 10
- After the test run has been completed inspect the strainer at the inlet piping of the outside unit clean it if it is dirty 10
- After water has been completely filled in first run the pump only and then make sure that no air has been caught in the water cir culation system and the water flow rate is correct if any air has been caught or the flow rate is not enough the plate type heat exchanger may freeze measure any water pressure loss before and after the outside unit and make sure that the flow rate is as designed in case of any abnormal stop the test run immediately and carry out trouble shooting to resolve the trouble 10
- Before entering the season for use carry out the following inspections 10
- Before starting a test run please make sure that the piping work has been carried out in a proper manner especially make sure that the strainer air discharge valve automatic water supply valve expansion tank and cistern are positioned at their places correctly 10
- Carry out complete cooling thermal insulation of water piping and outdoor dehumidification if complete cooling or thermal insula tion has not been carried out any damage may be caused during severe winter due to freezing in addition to thermal loss 10
- 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 10
- English 10
- Following the installation manual carry out a test run of the out side unit 10
- Management of chilled water flow rate if the chilled water flow rate is not enough it will result in the freez ing damage to the plate type heat exchanger check for any clog ging of the strainer any air being caught any reduction in the flow rate due to failure of circulation pump by measuring the tempera ture and pressure differences at the inlet and outlet ports of the plate type heat exchanger if the aged difference in the tempera ture or pressure has increased beyond the proper range the flow rate should have decreased stop the operation and remove the cause before restarting the operation 10
- 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 atten tion 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 10
- 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 40 c or higher and if metals with no protective coating whatever are directly exposed to water it would be a good idea to take effective measures against corrosion such as adding a cor rosion 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 corrosion and scale 6 once through water may cause corrosion do not use once through water 10
- 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 operation if the freezing protection device has been once acti vated a partial 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 10
- 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 maintenances at a regular interval in order to prevent the scale from being generated 10
- Water quality standards for chilled water hot water and make up water 4 6 10
- When you stop operation during night or winter it is necessary to take measures to prevent water related circuits from natural freez ing in the area the ambient temperature drops below 0 c by water drain off keeping the circulation pump running warming up by a heater etc freezing of water related circuits may result in any damage to the plate type heat exchanger therefore please take appropriate measures depending on the circumstances of use refer to figure 7 1 example of piping 2 water inlet piping 3 strainer sold separately as an accessory 4 air discharge plug for joint use with cleaning port 5 cleaning device 6 strainer for pump 7 automatic air discharge valve 8 water outlet piping 9 joint use with water draining plug 10 plate type heat exchanger 11 outside unit 10
