Regular cleaning of the air heat exchanger: one is to circulate and clean, that is, to circulate the cleaning liquid (the cleaning liquid can be heated very well) through the circulating pump, which is better for cleaning after scaling.
If the plate changing channel is blocked by impurities, it can only be cleaned by disassembly. Before the loose nut, measure the clamping scale and record it. Then loosen the nut diagonally and push the clamping plate back to the rear support plate. It can be cleaned and cleaned up after the cleaning is finished (if the sealing gasket is damaged, it needs to be replaced with a new one), and the diagonal angle can be clamped to the recorded scale.
The advantage of the first cleaning method is that the cleaning is convenient and the disadvantage is that the cleaning is not clean. The advantage of the second cleaning method is that the sheet can be cleaned very cleanly.
The disadvantage is that it is difficult to disassemble and replace the sealing gasket.
