Analysis of the considerations for the installation of industrial chillers

The vapor compression chiller includes four main components of the vapor compression refrigeration cycle (compressor, evaporator, condenser, part of the form of metering device), these machines can realize different refrigerants. The following items should be noted during installation:
  一. Please check whether the machine is damaged during installation? Choose a suitable place for installation and future maintenance.
  二. The place where the unit is installed must be the floor, installation mat or foundation, whose levelness is within 6.4mm? It must be able to bear the operating weight of the unit.
  3. The unit should be placed in a computer room with a room temperature of 4.4-43.3℃? There should be enough space around and above the unit to facilitate routine maintenance.
  4. At one end of the unit, there should be a space for cleaning the condenser tube bundle? You can also use door openings or other suitable openings.
   5. Choose the appropriate pipe diameter? Cooling system and cold water system when the unit is running at maximum power? And connect it correctly.
  6. For ordinary applications? The water flow speed through the evaporator and condenser is allowed to be between 1.0-3.6m/s.
  七. Under any load conditions? Water flow should remain stable.
   8. The design and installation of all chilled water and cooling water pipelines should be carried out according to conventional methods? The chilled water pump should be located on the inlet pipe of the unit? To ensure the positive pressure and flow in the unit. When piping should be provided with a damping pipe to ensure proper elasticity? It should also prevent the water from the evaporator from being drained when the pump is stopped. The pipeline should have a firm support independent of the chiller to avoid stress on the components of the chiller. The hanger should be set up to facilitate pipe alignment.
  九. In order to reduce noise and vibration, it is best to install vibration isolators on the pipeline.
  10. In order to use the chiller unit economically and effectively, it is recommended to ask a water treatment expert to analyze the water quality of the evaporator and condenser? Poor water quality will cause fouling and affect heat transfer? Or cause corrosion precipitation and growth of organic matter? Affect the unit's performance Performance? Increase operation and maintenance costs. Bus processing machine
  11. Generally speaking, correct water treatment and regular cleaning of the tube bundle can maintain its good performance? If the existing water quality conditions cannot be improved by appropriate methods, then it is necessary to consider allowing the tube bundle to have larger dirt Coefficients or designate specialized structural materials.
  12. Please install a filter at the entrance of the water pipe? And clean it regularly.
  13. After the leak test is completed, all the nozzles must be rust-proofed.
   In order to facilitate daily maintenance work during installation? Users can adopt some (or all) of the following measures: A. Pressure gauges and shut-off valves with plugs can be installed on the inlet and outlet pipes of cooling water and chilled water? Try to be as close as possible to the cold water Unit; Hanging rails and beams can be erected above equipment B to facilitate maintenance.
