Test results
Congratulations. You have passed the test and completed the 29 - Introduction to temperature control
Achieved badges:
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.
Q: How have temperature control systems traditionally been regulated?
A: Constant pressure valves regulating the amount of water entering the heat exchanger.
Q: How have temperature control systems traditionally been regulated?
A: Three way valves controlling the amount of water entering the pump.
Q: What is the expected payback time of an investment in system optimisation?
A: 1-12 months
Q: What is the expected payback time of an investment in system optimisation?
A: 1-5 years
Q: What is the expected payback time of an investment in system optimisation?
A: System optimization is rarely economical valuable but should be done due to environmental concerns
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.
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.
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.
Q: Which load profile will benefit the most from a demand driven control system?
A: Low flow rate with relatively few peak periods during the day.
Q: Which load profile will benefit the most from a demand driven control system?
A: High flow rate with relatively few low flow periods during the day.
Q: Which load profile will benefit the most from a demand driven control system?
A: Varying flow rate with relatively often periods with full flow and no flow.
Q: What is the ratio between the capital investment and running costs of a temperature control system?
A: 20:1
Q: What is the ratio between the capital investment and running costs of a temperature control system?
A: 1:1
Q: What is the ratio between the capital investment and running costs of a temperature control system?
A: 1:20
Q: Which temperature control systems hold the greatest potential for optimisation?
A: Temperature controlled pump in single circulation systems.
Q: Which temperature control systems hold the greatest potential for optimisation?
A: Unregulated temperature control systems that do not adapt operation according to the load.
Q: Which temperature control systems hold the greatest potential for optimisation?
A: Three way valve Regulated temperature control systems that adapts operation according to the load.
