A typical Carrier HVACR unit incorporates a high-pressure safety switch that operates at 610 psi and a low pressure (loss of refrigerant detection safety device) that operates at about 20 psi. See moreOct 31, 2023 · The maximum recommended temperature is often around 150 to 160 degrees Fahrenheit (65.6 to 71.1°C) for the condenser coil. What is normal subcooling for 410A? Normal subcooling for R-410A systems can range from 10 to 20 degrees Fahrenheit (5.6 to 11.1°C) depending on the specific system design and conditions. One for heating and one for cooling. At a given outdoor ambient, indoor wetbulb and dry bulb, the suction and discharge pressures should intersect on a graph at specific temp readings along a curve on the graph. Also, as Houston said, there should be a desired subcooling reading at the outdoor unit.An air conditioner or heat pump using R-410A refrigerant may operate at pressures exceeding 600 psi. A typical Carrier HVACR unit incorporates a high-pressure safety switch that operates at 610 psi and a low pressure (loss of refrigerant detection safety device) that operates at about 20 psi.How to Read an R-410A PT Chart. 1. Identify Desired Temperature. Determine Temperature: Choose the required temperature for your system based on its application or specific needs. 2. Find Corresponding Pressure. Locate on Chart: Find the selected temperature on the P-T chart and note the corresponding pressure in psig (pounds per square inch ....
