High head pressure

Low suction pressure and high head pressure is a condition where there is a decreased refrigerant pressure in the AC system and at the same time a high output pressure in a compressor. This condition is mainly caused by a defective or malfunctioning TXV valve. An expansion valve is a device that regulates the flow of the liquid refrigerant into ...

When you have a high efficient heat pump it requires a matched indoor coil. An example would be indoor coil is to small and the outdoor coil is very large causing an imbalance. If the system was charged in the cooling mode it could be overcharged when the unit goes into heating mode. Reply. 02-02-2009, 08:43 PM #4.A typical pressure control setup is shown in Table 1. Excluding a cold, windy day, where the wind is able to blow through the tube bundle on the condenser, the head pressure would never fall below 160 psig with this control strategy. While this is a simple method of control, it does have a few disadvantages.If your blood pressure readings are suddenly higher than 180/120, wait five minutes and test again.
