13 Jan 2020 How to Read a Navigational Chart: The Basics. a black and white shot from behind a sailor mapping out a route with a compass  Learn how to read saturated and superheated steam tables. a large number of superheated steam tables use representative pressure-temperature values to 

With the blend you read the saturated temperature next to the pressure in the liquid (bubble point) column of the chart. For a single-component or azeotropic refrigerant, the operating pressure for the low side of a system can be found by cross referencing the desired coil temperature on the PT chart. PT charts show the relationship between pressure and temperature of given refrigerants. By changing the pressure of the refrigerant, the technician can set its temperature to a given level. Put the pressure temperature chart in front of you. Determine whether temperature or pressure is provided in the left column. PT Chart 101 johnnyhvac. Loading Unsubscribe from johnnyhvac? How to Read the HVAC P/T Chart for the Refrigerant Pressure Temperature Relationship! - Duration: 11:00. This video will show you the basics on reading a refrigerant pressure temperature chart. Follow these tips and you cant fail. PT Chart Index. Charts use °F and psig. SI Charts are available for SI Boards. Colours show AHRI GUIDELINE N-1995 refrigerant container colour assignment. AHRI is now specifing that all refrigerant containers should have one uniform paint color, grey RAL 7044 and that the previously assigned colors should be transitioned Review Questions

Before you have surgery your doctor may order blood tests to determine how quickly your blood clots. This group of tests is known as a coagulation study. Individually these tests are commonly referred to as a prothrombin time (PT), partial thromboplastin time (PTT), and international normalized ratio (INR).

Using the P-T Chart to Diagnose Refrigeration, A/C System Problems Fig. 1 shows a normal operating system where the highside contains refrigerant in three conditions. Fig. 2 shows a system running on HFC-134a and conditions of the refrigerant at the various points. Using a PT chart or pressure temperature chart one can determine the pressure or the temperature of the refrigerant. To properly charge an HVAC air conditioning or heat pump system one needs to use the PT chart or pressure temperature chart, a set of manifold gauges, Take a reading of your refrigerant system pressure (PSIG). Find the corresponding saturated pressure for your refrigerant. Superheat (for units with fixed metering device): Compute the superheat by determining saturated suction temperature from Temperature Pressure Chart. Subtract from actual suction line temperature before compressor. Refrigerant Pressure Temperature Chart | HVAC Refrigeration - This page offers a temperature pressure relationship chart for use in working with HVAC Systems that use R-410A, R-22, and R-134A.
