Johnson Controls Ducted Systems Technical Guide: R-410A Outdoor Split-System Heat Pump - RHP143 York International Corporation, 5005 York Drive, Norman, OK 73069 What are the normal operating pressures for 410a high and low side in a 2 ton heat pump? 125 PSI for low and 365 PSI for high, the high can vary as the outdoor temperature does, basically on an 85 degree day you should see about 365. It can get up to 400 PSI on a 95 degree day.And 500 PSI on a 110 degree day.

The thermometer shows us that the superheated R-410A vapor is at 54°F temperature. Now we can calculate R-410A superheat: Superheat (R-410A) = 54°F – 51°F = 3°F. In this case, we have a dangerously low 3°F superheat. This presents a risk that the suction line will deliver liquid R-410A to a vapor-only compressor and flood it.assembled, piped and wired at the factory to provide a single-piece. unit for shipment and rigging. Each unit is pressurized with a holding. charge of refrigerant R-410A for storage and/or shipping. The compact design, clean styling, small footprint, and quiet operation. make these condensing units and heat pumps suitable for almost any.Let's get started and see what we can do.Most manufacturers recommend charging by super heat and subcoolimg rather than pressures alone,and will vary slightly by manufacturer but as a rule low side of about 110 and high side about 280at 70 degree ambient. This will of course increase as temp warms up.ON an 85 degree day,probably 130 to 135 and ...The maximum recommended temperature is often around 150 to 160 degrees Fahrenheit (65.6 to 71.1°C) for the condenser coil.

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. These units use R-410A refrigerant which operates at 50 to 70% higher pressures than R-22. Use only R-410A approved service equipment. Refrigerant cylinders are painted a “Rose” color to indicate the type of refrigerant and may contain a “dip” tube to allow for charging of liquid refrigerant into the sys-tem. I don't understand how a 410A heat pump can have low subcooling, 2.5 degrees. Have added refrigerant and it got up to 7 than would not go any higher , in fact the head pressure came down some. I would think if it was enough to bring the pressure down it would be stacking the refrigerant and subcooling would get higher.Here are some of the symptoms of this system: • Higher than normal discharge temperatures; • Low condensing (head) pressures and temperatures; • Normal to high condenser subcooling; • Normal to high superheats; • High evaporator (suction) pressures; and. • Low amp draw. Higher than normal discharge temperatures:A …

Panasonic had a competing "Aquarea" air-to-water heat pump system using R410A launching in Europe shortly after the take over to compete directly against …If mini-split Inverter AC (Heat pump) with R-410a refrigerant is over-charged. Does the pressure reading on suction/vapor side increase as well (measured while AC is running)? Read that when its working at full-speed cooling mode (lowest temp, highest airflow) the suction pressure should be 120-130psi. If some tech overfills the unit with ...The low suction pressures may cycle the compressor off prematurely. After a short period of time, the evaporator pressure will slowly rise from the small amounts of refrigerant in it and the heat load on it. This will cycle the compressor back on. This short cycling may keep occurring until the compressor overheats.This rule is totally a fluke and has no scientific basis other than it just generally tends to work out that way. On a properly functioning R-22 system running in heat mode in 40-degree weather, the suction pressure tends to be around 40 PSIG. This guideline obviously doesn't work on an R-410A system or any other refrigerant.pressures and refrigeration capacity than R-22.
