Congratulations. You have passed the test and completed the 29 - Introduction to temperature control
Achieved badges:
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.
