Achieved badges:
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: 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: Why is ammonia an efficient coolant?
A: Ammonia is able to absorb large amount of heat when it evaporates.
Q: Why is ammonia an efficient coolant?
A: Ammonia is easy to pump.
Q: Why is ammonia an efficient coolant?

Q: What is the most efficient and simple way of controlling heating, cooling and refrigeration systems?
A: Intelligent three way valves controlling the amount of water to the pump and heat exchanger accordingly.
Q: What is the most efficient and simple way of controlling heating, cooling and refrigeration systems?
A: Intelligent pumps equipped with temperature sensors that measure the outlet temperature and signal the pump to regulate its flow accordingly – without the use of valves.

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
