A water pump in water cooled chiller system work the same as a human heart

When a water cooled chiller heat exchange system efficiency drop, the water pump has to work harder and will consume more electricity. Likewise, in a case when a human body blood circulation system efficiency drop, the human heart has to work harder and use up more oxygen.

A water cooled chiller heat exchange system need water with chemicals treatment, similarly a human body system need water and food rich in Vitamin E, calcium, magnesium, potassium etc... to improve blood circulation and to prevent blood clots.

Vitamin E is to reduce the need for oxygen in human body therefore Vitamin E is an antioxidant.
