Maintenance of air-cooled heat pump of PACKAGE BOCK CONDENSING UNIT
In order to ensure the effective work of PACKAGE BOCK CONDENSING UNIT, its outer layer must be free from any fallen leaves, lint, insects, slag shells and other pollutants. If the condenser needs to be cleaned, the compressed air should be blown parallel to the aluminum from the inside to the outside to dissipate heat. sheet, the direction is just opposite to the normal air circulation direction. When doing external cleaning, you can use a vacuum cleaner, do not damage the aluminum fins.
PACKAGE BOCK CONDENSING UNIT's Plate Heat Exchanger
If you want to determine whether the shell and tube heat exchanger is clean, please check the water temperature at the water inlet and outlet of the heat exchanger and compare it with the saturated evaporation temperature. For an effective heat exchanger, the water temperature at the water outlet is 5-7 degrees higher than the saturated evaporation temperature of the refrigerant. If the temperature difference exceeds this value range, it indicates that the working efficiency of the heat exchanger is reduced. Since certain chemical treatments are required in the cleaning process, cleaning must be done by professionals.
Freeze Protection of PACKAGE BOCK CONDENSING UNIT
The drain valve on the shell and tube heat exchanger of PACKAGE BOCK CONDENSING UNIT has been installed with a drain valve. When the unit is not used for a long time when the ambient temperature is lower than 0 degrees, the water in the shell exchange must be drained through this valve, otherwise the unit will be drained. The water system will be damaged by freezing; if the unit needs to run when the ambient temperature is lower than 0 degrees, please power on the unit so that the unit can automatically enter antifreeze operation when needed.
