An R-22 evaporator running at 40F saturation temperature will have a corresponding pressure of 68.5 psig. Should the suction pressure drop below 57 psig, the coil temperature will drop below 32F causing moisture in the air to freeze on it (see Figure 4) causing no end of trouble. A R-410A evaporator running below 100 psig will freeze-up just ...Oct 11, 2017 · With this higher pressure from 410A comes a need for new tools. Let’s take a look: Manifold Gauge Set – The high pressures encountered when working R-410A requires a manifold gauge set that has a low-side gauge that can read up to 500 PSIG and a high side gauge that can read up to 800 PSIG. This is significantly higher than a standard ... The low ozone depletion potential (ODP) of R-22 compared to CFC-11 (chlorofluorocarbon 11) and CFC-12, as well as its excellent refrigerant properties have helped facilitate ... Freon™ 410A are shown in Table 3. The pressure-enthalpy diagrams for Freon™ 407C are shown in Figures 1 and 2. Additional physical property data may be found in other …The high side guage was connected to the liquid line. Static, both guages are 160 psig. When the unit ran, BOTH guages dropped to about 130. The high side was perhaps 2-5 higher. The amp draw at the compressor was 8.6 RLA out of a 22.1 suggest maximum on the equipment sticker.In heat mode, a dirty air filter causes low airflow across the condenser. That can cause extremely high head pressure. In heat mode, a dirty outdoor coil can cause a low suction pressure. As an example, Trane includes a pressure curve chart with many heat pump condensing units. Be sure to use the scale all the way to the right that says heat mode.What are 410a pressures on a 95 degree day? The typical 410a pressures on a 95 degree day are as ...

Aug 6, 2018 · This causes high compression ratios and low volumetric efficiencies, which results in low refrigerant flow rates. In summary, there are seven symptoms or telltale signs of a system that has too much refrigerant. High discharge temp. High subcooling in the condenser. High pressures in the condenser. Higher condenser splits. The first thing to realize is that when a system is off and equalized, the system’s pressures on both the high side and the low-pressure side will match. In the example of an R-410A packaged unit with a surrounding air temperature of 70°F, the pressure on both the high and low-pressure side of the system will be 201 PSIG. If a new R-410A ...rmosden, hvacmatt123 liked this post. A cold suction line (low superheat) with low suction pressure is a symptom of low evaporator air. A liquid restriction would result high superheat (warm suction line). The high head probably due to the other guys overcharging, trying to get the suction pressure up.High Suction Pressure R-410a. i went to check an 3.5 ton a/c brand is a ICP (international comfort products) Model WAPL424A1, not cooling my pressures were low side 185 to 190 and high side was around 350 on a 107F hot day. It has a piston as a metering device and compressor was running at 11.50 amps and RLA is 17.25 amps.The low side is running about 165 and the high side is 365. The low side was high like this before I change out the coil. I that case the charge was low, but I would of expected a lower pressure on the low side. IT about 97 out side right now. The unit calls for a sub cool number of 12.
