Special attention should be paid to equipment selection in locations with high ambient conditions—outside air temperatures above 95°F. For example, in Las Vegas, with ambient temperatures at 115°F and above, the equipment de-rating can be as high as 30%. WebWhat causes high head pressure in refrigeration? Once the air gets to the condenser, it will remain at its top and not condense. The subcooled liquid seal at the condenser's bottom will prevent the air from passing out of the condenser. This air and water vapor will take up valuable condenser surface area and cause high-head pressures.
