Refrigerant R22 has approximately 55% higher refrigerating capacity and pressure levels than R12**. The significantly higher discharge gas temperature is also a critical factor compared to R12 ( R12/R22 - comparison of discharge gas temperatures) and R502**. Similar relationships in terms of thermal load are found in the comparison with HFC.

The PT Chart typically lists the pressure on the left, and the corresponding refrigerant boiling point on the right. Refrigerant at these conditions is referred to as saturated. Saturated refrigerant can be 100% vapor, or a mixture of liquid and vapor, or 100% liquid. At temperatures above saturation, the refrigerant becomes super-heated vapor.

In summary, R410A and R32 have better system performance and require a smaller refrigerant charge. But an important problem is that the exhaust temperature of R32 is higher. The direct consequence is that oil degradation can cause various compressor failures, such as bearing seizure, low system performance, and low compressor performance.

The net refrigeration effect, or evaporator cooling, is the difference in specific enthalpy of the evaporator, or, 175.41- 109.3 = 66.11 Btu per pound of refrigerant. Three tons of cooling is 600 Btu/minute. Divide 600 by 66.11 and you get the refrigerant flow of 600 / 66.11 = 9 pounds per minute of refrigerant flow required to meet the capacity. This is determined by a refrigerant slider. To determine the evaporation temperature, set the slide on 'dew'. To determine the condensation temperature, set the slide on 'bubble'. 4. Use a digital thermometer to measure the temperature on the installation. Measure the superheating temperature on the suction pipe.

The pressure-enthalpy chart, as shown in Fig. 2, displays all the pertinent properties for a given refrigerant (in this example R22). The bubble to the left is the portion of the diagram where the refrigerant is in the saturated condition. The blue line on the left of the bubble represents the 100% saturated liquid line,.

Refrigerant R-410A Pressure Temperature Chart. - This R410A PT Chart will help you when charging a system that utilizes R-410A. Furthermore, R410A is an HFC and is commonly used in residential and light commercial HVAC equipment for air conditioners and heat pump systems. Additionally, it widely replaces HCFC R-22 which was mandated by the.

Refrigerant Oil Basics. First, here's a quick summary of the role of oil in the refrigerant circuit: The compressor requires oil for the lubrication of the moving parts in the compressor. We would keep 100% of the oil in the compressor if we could. However, that is generally unrealistic. So, we need to utilize oils and oil strategies that will. The only way to ensure you got the right charge in the system is by weight. By reclaiming the charge and weighing the correct charge in. Further more, R410a is a blend of two refrigerants and if you had a significant leak then it is likely that the mixture of the remaining gas is no longer R410a, therefore if you had a leak the best practise is to recharge with virgin.

145 °F. 571.7 psig. 150 °F. 607.6 psig. 155 °F. 645.2 psig. You can see that this R410A pressure chart includes high and low side pressures at temperatures ranging from -60 °F to 155 °F. Here are 4 examples of how you can use this chart:.

Note on the chart: You will see that the pressure of R134A drops from 18.4 psig at -49°F to 0 psig at about -14.9°F. This is the boiling point of R134A; it’s when liquid 134A is turned into gas. From that temperature onwards, the pressure of R134A is increasing with the temperature reaching 262.9 psig at 150°F..

. Inside the condenser, after all of the refrigerant vapor has condensed into liquid, the refrigerant is subcooled to further lower its temperature. This subcooled liquid refrigerant leaves the condenser (A) and experiences a pressure drop as it flows through the liqui d line and accessories , such as a filter Thermostatic Expansion Valve (TXV). The pressure-temperature (PT) chart is a valuable tool that service technicians use to check proper system operation. PT charts are most often used for three purposes: to set a coil pressure so that the refrigerant produces the desired temperature; to check the amount of superheat above the saturated vapor condition at the outlet of the evaporator and to check the amount of.

Answer (1 of 3): Pressure of refrigerant in a split phase AC is not determined by the tonnage of an AC, but the particular refrigerant you are using in that 1.5 ton system. Meaning a 1.5 tone AC may require 60psi of R22 but the same system would require 40psi of R407c. R22, R410a, R407c, etc may.
