Here are 4 examples of how you can use this chart:In this video we go through the basics of checking a heat pump charge in heating. It can be tricky but its pretty simple if you do this..Title music:Music: B...When you have an R-410a heat pump, I understand that in A/C mode the indoor coil is the evaporator and that the smaller copper line is liquid/high pressure and the larger line is vapor. So, when it is in heat mode, that is reversed -- but are the pressures also reversed?

In heat mode, a dirty air filter causes low airflow across the condenser. This 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.

present at the heat pump/defrost control The heat pump/defrost control will attempt to start unit after the anti-short cycle time expires, when a high or low pressure control automatically resets, or when the heat pump/defrost control exits the lockout mode as the temperature rises above 5°F The calculation for charging refrigerant is critical in heating mode. The overcharging of the refrigerant leads to many unwanted problems in the system. One of the primary cause of head pressure to be high is the overcharging of the refrigerant. High head pressure on heat pump. The high head pressure in any device deteriorates the performance. Reply: The requirement to re-charge an air conditioner or heat pump system might be suggested by cooling coil icing or by complete loss of cooling, or by very low suction pressures, or very low head pressures, but short of those extremes, pressure readings won't tell you if the quantity of refrigerant that's in the system.The unit was charged in heating mode and 11lbs 1 oz of refrigerant was used. When the heat pump is running it blows semi-warm air like it is operating correctly but when I put my gauges on the system the high side pressure was 425 and low side was 395-400.VARIABLE SPEED R-410A HEAT PUMP OUTDOOR UNITS INSTALLATION INSTRUCTIONS 92-105074-09-00 (3/16) Printed in USA [ ] indicates metric conversions.

Typical High Side Pressure Range for R410A in the field: 410-420 psi. By 2025, high Global Warming Potential (GWP) refrigerants with a GWP of over 750, will be banned together with the systems using that gas. R410A has a GWP > 2,000.In the cooling mode, running in outdoor temperatures below 55 degree without a "low ambient control' will cause symptoms very similar to low refrigerant. The cold outside air will cause the head pressure to drop which, in-turn, causes the suction pressure to drop. Try blocking part of the outdoor fan discharge to increase head pressure.

Step #2 - Check all the obvious things first, filter, coils, blower wheel etc… If the unit isn't clean, it will be really hard to check. When charging in heat mode, read manufacturer specifications first.However, the maximum high side pressure could go up to about 450 psi, especially in hot and humid countries. Even in cold and dry countries, inefficient heat transfer due to dirty filters and coils will increase the high side pressure. In heat mode, the highest pressure an R410A mini split can even reach to around 500 psi. The high side pressure, in contrast, refers to the refrigerant pressure in the discharge line. This is basically the pressure after the compressor. Even though the ideal pressure range for an R-401A air conditioner falls in the range of 110-140, its low side pressure should not be less than 100 psi, nor should it be more than 160 psi. Why this ... 20-May-2012 ... At 60°C the refrigerant R134a will be at an overpressure of around 16 bar, R407C (dew point) at 24 bar and R410A at 37.5 bar.
