The circulating heat transfer medium is<br \/>\ndifferent. Generally, the high and low temperature cooling system industry<br \/>\nmostly uses direct cooling, while the high and low temperature recirculation<br \/>\nchiller system mostly uses indirect cooling with internal installation. There<br \/>\nare devices such as plate heat exchangers or oil coolers. The heat medium and<br \/>\ncooling water source in the system exchange heat in the heat exchanger to<br \/>\nreduce the temperature of the medium.<\/span>\n<\/p>\n<p class=\"MsoNormal\">\n\t<span><\/span>\n<\/p>\n<p class=\"MsoNormal\">\n\t<span>Generally, we conduct investigation and<br \/>\nmaintenance from the following aspects:<\/span>\n<\/p>\n<p class=\"MsoNormal\">\n\t<span>1. The cooling solenoid valve is damaged:<br \/>\nit is necessary to check whether the solenoid valve coil can work normally, if<br \/>\nit is damaged, it needs to be replaced; the panel does not output a cooling<br \/>\nsignal, carefully check the circuit or use the component replacement method to<br \/>\ncheck.<\/span>\n<\/p>\n<p class=\"MsoNormal\">\n\t<span><\/span>\n<\/p>\n<p class=\"MsoNormal\">\n\t<span>2. Circuit failure: Check the circuit part<br \/>\nof the system, the cooling water inlet or outlet pipeline is blocked: check<br \/>\nwhether the valve in the cooling water pipeline is fully opened, and ensure<br \/>\nthat the flow and pressure of the cooling water are sufficient, and the heating<br \/>\ncontactor is stuck, Always heating: observe the pull-in state of the contactor,<br \/>\nand worsen damaged electrical parts.<\/span>\n<\/p>\n<p class=\"MsoNormal\">\n\t<span><\/span>\n<\/p>\n<p class=\"MsoNormal\">\n\t<span>In addition to troubleshooting the above<br \/>\nseveral possible causes of failure, we also need to check whether the cooling<br \/>\nplate is replaced or the cooling exchanger is blocked. The advantage of using<br \/>\nindirect cooling is that it has high temperature control accuracy and strong<br \/>\nadaptability. It can be applied to the temperature control of high and low<br \/>\ntemperature recirculation chiller systems, and because the heat transfer medium<br \/>\nis cooled first, the cooling impact on the temperature control equipment is<br \/>\nrelatively relatively large. Of course, the disadvantage is that the cooling<br \/>\nspeed is relatively slow, and the price is more expensive than the direct<br \/>\ncooling method.<\/span>\n<\/p>\n<p class=\"MsoNormal\">\n\t<span><\/span>\n<\/p>\n<p class=\"MsoNormal\">\n\t<span>If you can&#8217;t solve it by yourself, you need<br \/>\nto contact the manufacturer of the high and low temperature recirculation<br \/>\nchiller system to solve it in time to avoid delays and increase costs.<\/span><\/p>","protected":false},"excerpt":{"rendered":"<p>When the high and low temperature recirculation chiller system is in use, what is the general cause if the high temperature cannot be reduced?
