2: What is the benefit of aligning primary side flow with secondary side flow?
To avoid or minimise the ‘low’ Delta T syndrome
3: How do variable-speed pumps affect the manual balancing process in HVAC systems?
Variable-speed pumps make the manual balancing process obsolete by automatically balancing the system according to actual demands.
3: How do variable-speed pumps affect the manual balancing process in HVAC systems?
Variable-speed pumps require manual balancing to be performed more frequently to maintain system efficiency.
