Q: Why does a cooling system using propylene glycol require pumps with oversized motors?
A: Because the viscosity and density of propylene glycol is higher than tap water.
Q: Why does a cooling system using propylene glycol require pumps with oversized motors?
A: Because the viscosity and density of propylene glycol is lower than tap water.
Q: Why does a cooling system using propylene glycol require pumps with oversized motors?
A: Because propylene glycol has a lower specific heat capacity and therefore requires a higher flow.
Q: What method does Grundfos recommend to control the transference of energy in a heating, cooling, or refrigeration system?
A: Using constant-speed pumps with throttling valves to regulate the amount of water entering the heat exchanger.ng the heat exchanger.
Q: What method does Grundfos recommend to control the transference of energy in a heating, cooling, or refrigeration system?
A: Installing intelligent pumps equipped with temperature sensors that measure the outlet temperature so the pump can adjust its flow accordingly.r.
