Steps to clean the chiller: Shut off the water source of the chiller and clean up the water inside the unit components and pipes to prevent the residual water from corroding the unit components after shutdown, or the copper pipes from freezing due to too low temperature; at the same time, the drain nut under the water pump should be unscrewed to drain the residual water in the water pump to prevent the water system from freezing due to too low ambient temperature.
The evaporator ruptures and causes refrigerant leakage or water pump impeller damage. The cleaning and maintenance of the chiller should not be taken lightly in autumn and winter! Turn off the power and check whether each component is worn (if there is, it needs to be replaced); clean the fan of the air-cooled chiller and keep it in a clean state.
Check the water tank of the water tank coil evaporator for scale and other debris and remove them; the cleaning and maintenance of the chiller should not be taken lightly in autumn and winter! Understand the use of lubricating oil through data records, and replace the lubricating oil regularly according to the application specifications to maintain a good lubrication state.
It is necessary to insulate the chiller water pipes, because pipe insulation can not only prevent the serious loss of cold, but also prevent the formation of condensation on the outer wall of the pipe. For example: the ice water temperature is 10 degrees, the ambient temperature is 30 degrees, and the heat radiation of a 25-meter-long metal pipe with an outer surface area of 25 square meters can be 750kcal/h.
