Hvac head pressure

WebWe know that the total pressure in a closed loop chilled water system is static pressure plus dynamic pressure, the higher the water velocity, the greater the dynamic pressure. Thus, total pressure does increases with the pump head. Let’s say we double the water velocity. So, the new dynamic pressure is: Pd = 0.5ρv2. WebVarious experts and professionals claim that head pressure for a 410A system should be 400 to 418 PSIG on the high side while 120 to 130 PSI on the lower side. Anything more than this range is considered high head pressure. This value may vary a little bit depending on the weather and other external conditions. What causes high head pressure HVAC
