07.
Q: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
A: The viscosity and density of propylene glycol is higher than tap water.
07.
Q: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
A: The viscosity and density of propylene glycol is lower than tap water.
07.
Q: Why does a cooling system that uses propylene glycol as coolant demand pumps with oversized motors?
A: Propylene glycol has a lower specific heat capacity and therefor requires a higher flow.
08.
Q: How have temperature control systems traditionally been regulated?
A: Constant speed pumps and throttling valves regulating the amount of water entering the heat exchanger.
08.
Q: How have temperature control systems traditionally been regulated?
A: Constant pressure valves regulating the amount of water entering the heat exchanger.
08.
Q: How have temperature control systems traditionally been regulated?
A: Three way valves controlling the amount of water entering the pump.
