ABSTRACT:
The liquid level in at least one flash economizer associated with a refrigeration process is maintained at a desired level by controlling the flow of the liquid leaving the flash economizer in response to a control signal which is responsive to the difference between the actual liquid level in the flash economizer in the desired liquid level. The liquid level in the chiller associated with a refrigeration process is maintained by controlling the flow of fluid to the flash economizer in response to a control signal which is responsive to the difference between the actual liquid level in the chiller and the desired liquid level.
