From 1.6 MPa to 0.9 MPa: Why Does the Same Valve "Lose Strength" at High Temperatures? — A Guide to Using Pressure-Temperature (PT) Rating Curves
The pressure temperature rated curve (PT curve) - it determines whether the valve can be used under your operating conditions, and how much heat and pressure can be used.
Should It Close or Stay Open During a Power Failure? — Safety Guidelines for Selecting Normally Closed vs. Normally Open Solenoid Valves
When the power is lost, the valve core closes by the spring force, and when powered on, the electromagnetic force overcomes the spring and opens.
What are the common symptoms of HVAC system malfunctions?
When cooling, the air outlet temperature is ≥ 15 ℃, when heating is ≤ 30 ℃, or the temperature difference between different areas in the same room is>3 ℃ - mostly due to filter blockage, dirty coils, refrigerant leakage, or hydraulic/air volume imbalance.
What problems can arise from an unreasonable HVAC system design?
High initial investment and space occupation; Frequent start stop of equipment, shortened lifespan, insufficient dehumidification, and indoor humidity.
