First of all, due to the installation or piping of the air heater properly, the air heater is lower at the lower point of water, and as time is extended during the winter operation, the air heater will easily freeze in the tray of the air heater, therebyCauses the frozen cracks of the air heater damage.
The second is that when the air -conditioning system is designed, the heat exchange area for the air heater used for fresh air preheating has a large amount of balance. During the winter operation, due to the large amount of heat exchange area, the operator is adjusting the thermal media to adjust the heat media.During the flow, control the heat media flow rate is too small, so that the content of the new wind side pipe of the air heater is easy to freeze and frozen cracks damage the air heater.
Finally, the air -conditioning system that is only delivered in the winter in winter. Due to the high temperature requirements of the indoor, in order to save energy, the operator controls the air heater heat media flow rate in the process of regulating the heat exchange of air heater.Make the air heater frozen and freeze the heat exchanger.
Through the introduction of the above three points, everyone knows how to protect the air heater in winter?Welcome new and old customers to visit and guide ——
