What to consider when choosing a chiller. Determination of basic parameters.

1. Is the condenser cooled by air or water?

  • Where will the condenser be located, indoors or outdoors?
  • It is necessary to consider convenience of service, height of a ceiling, obstacles, walls, the maximum and minimum ambient temperature.
  • If water cooling — what is the source of coolant?

  • Highest and lowest condenser coolant temperatures?

  • Is filtration required before the coolant enters the chiller condenser?

2. Monoblock chiller or with a remote condenser?

  • Location of the cooling system — indoors or outdoors?

  • Placing a chiller or condenser needs consideration.

3. How accurate temperature control is needed for your processes?

  • If strict temperature control is required, you will need a dual-circuit technological chiller to maintain a certain temperature in the onboard or separate tank.

4. What voltage is available for the future chiller?

  • What are the existing electricity network capacities at the facility where the chiller will be installed?

5. What liquid do you plan to cool?

  • Is filtering needed before entering?

  • Does the fluid contain corrosive or chemical substances that can damage heat exchange surfaces?

6.What are the estimated temperatures at the inlet/outlet of the chiller?

  • If the temperature is very high, a buffer tank or other measures will be needed to reduce the temperature difference at the inlet/outlet of the evaporator.

7. Direct cooling or through an intermediate refrigerant?

  • Determine: what type of cooling is needed?

  • What is the estimated freezing point of the refrigerant for the case of intermediate cooling (double-circuit system)?

8. What is the ambient temperature?

  • What is the lowest temperature of the liquid at the outlet of the chiller during operation?
  • What is the lowest ambient temperature (winter)?

  • What is the highest ambient temperature (summer)?

9. What volume of liquid needs to be cooled for a certain time?

  • It is necessary to indicate the estimated volume of liquid cooled over time (consumption of the consumer pump, cubic meters per hour).

10. Is a system pump required for the chiller?

  • Is there already a technological pump in the circuit?

  • If there is no pump, what are the flow and pressure requirements in the technological process?
