In the cold winter, heating in the north is very important. At this time, the plate heat exchanger plays a great role, but in the long-term use process, the plate heat exchanger will have insufficient heating temperature.
The reason for the insufficient heating temperature of the plate heat exchanger:
(1)The flow of the primary side medium is insufficient, resulting in a large temperature difference on the hot side and a small pressure drop.
(2)The scale inside the plate heat exchanger is serious.
(3) The flow distribution of multiple plate heat exchangers operating in parallel is uneven.
(4)The cold side temperature is low, and the cold and hot end temperatures are low.
