02.
Q: How much of the 30 % of water lost to evaporation can you potentially save by using the right control?
A: None
02.
Q: How much of the 30 % of water lost to evaporation can you potentially save by using the right control?
A: 5%
02.
Q: How much of the 30 % of water lost to evaporation can you potentially save by using the right control?
A: 20%
03.
Q: What does the hysteresis band do?
A: It ensures that the fan starts when you exceed a set temperature
03.
Q: What does the hysteresis band do?
A: It determines how low the temperature can be before the fan stops running
03.
Q: What does the hysteresis band do?
A: Nothing – it’s a made-up phrase
04.
Q: How does Grundfos iSOLUTIONS help the pump control the cooling tower?
A: By keeping the pumps running at constant speed
04.
Q: How does Grundfos iSOLUTIONS help the pump control the cooling tower?
A: Through variable speed and start/stop functions
04.
Q: How does Grundfos iSOLUTIONS help the pump control the cooling tower?
A: By using powerful fans
05.
Q: Does fixed-speed operation give you a greater control of energy use?
A: Yes
05.
Q: Does fixed-speed operation give you a greater control of energy use?
A: No
06.
Q: What is the main purpose of a cooling tower?
A: To transfer heat from the cooling water to the air by evaporation
06.
Q: What is the main purpose of a cooling tower?
A: To boost pressure in the distribution area
06.
Q: What is the main purpose of a cooling tower?
A: To keep a volume of water for emergency use
