What is the purpose of control valves in a three-pipe air conditioning system?

In a three-pipe air conditioning system, control valves are primarily used to regulate water flow effectively. They manage how much water flows through the system's various components, ensuring that each part receives the appropriate amount of water to maintain optimal performance and efficiency. This regulation directly impacts the system’s ability to heat or cool spaces efficiently.

Balancing pressure throughout the system helps to maintain consistent airflow and temperature control, but it is not the primary function of the control valves themselves. Similarly, while temperature monitoring is vital for controlling the air conditioning system, this is typically managed by thermostats or other sensors rather than control valves. The selection of heat exchanger pipes is not a function of control valves; instead, it refers to the design and layout of the system itself.

Therefore, understanding the critical role of control valves in regulating water flow clarifies their essential function within the overall operation of a three-pipe air conditioning system.
