Freon ™ 22 Refrigerant (R-22) Thermodynamic Properties (SI Units) Technical Information Tables of the thermodynamic properties of Freon™ 22 (R-22) have been developed and are presented here. Outdoor Temperature, If the superheat at the compressor (measured at the suction line close to its point of entry into the compressor) is more than 5°F above the chart reading you need to add refrigerant gas by low-side charging. The chart is available in PDF and JPEG formats. Share: Found a lower price? Let us know. eduardo zamora escondido *Red Italics Indicate Inches of Mercury Below Atmospheric Pressure Saturation Pressure-Temperature Data for R507 (psig)* Target Superheat Chart + Calculator, Formula, R22, 410A Examples; Understanding Superheat And Subcooling In HVAC: 101 Explanation; 6 Low Superheat Causes: Low CFMs, Overcharged Or Oversized AC; What Causes High Or Low Subcooling? 4 Culprits + Fixes; Low Superheat High Subcooling: It’s Overcharged AC, Here’s Why That’s not a term we use often, but enthalpy is just a measure of how much heat energy is in the refrigerant. ….
Superheated Refrigerant 134a Table We measure the actual superheat with the low side red gauge and clamp-on thermometer (on suction line). The bubble to the left is the portion of the diagram where the refrigerant is in the saturated condition. Checking with reputable linen and bedding companies through their online portals is an easy way to find size charts for each company’s pillows.
