The compressor is still cooling, but not to its rated capacity, which can cause refrigerated products to spoil faster and frozen products to begin to thaw. There are three main reasons why a compressor will simultaneously have a low head pressure and a high suction pressure: 1. Bad (leaky) compressor valves; 2. Worn compressor rings; and.180 suction line pressure 320 discharge 10 degree temp split. No temp difference across the filter drier. I cleaned coils and checked airflow just to eliminate the variables. I recovered the refrigerant, changed the filter drier, charged about 2lbs before starting the compressor and the low side shot right up to 170. System holds about 8 lbs total.Fig. 3.55 illustrates this by plotting the pump discharge head vs. flow for high- and low-suction tank conditions. The control valve, however, tries to maintain a steady pressure. As a result, the flow rate varies as the suction pressure varies. In some cases, the flow rate may drop to below the recommended minimum at very low head conditions.When a refrigeration system that produces low or no cooling has high suction pressure and high head pressure , it probably A. has an inefficient compressor B. has a low-side restriction C. is overcharged D. is undercharged. Refrigeration and Air Conditioning Technology (MindTap Course List) 8th Edition. ISBN: 9781305578296.Low Load. While we often think of the combo of low suction, superheat, and head pressure as being caused by low airflow, it actually falls under a larger heading of low evaporator load. That simply means that the quantity of heat being picked up in the evaporator is lower than the refrigerant mass flow rate requires for the desired operation.In search of more space and pressured by low inventory, home shoppers are flocking to new construction.
