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.

problems. Fluid flows from areas of high pressure to areas of low pressure. Pumps operate by creating low pressure at the inlet which allows the liquid to be pushed into the pump by atmospheric or head pressure (pressure due to the liquid’s surface being above the centerline of the pump). Consider placing a pump at the top of the mercury Suction Head. Based on the Energy Equation - the suction head in the fluid close to the impeller *) can be expressed as the sum of the static and velocity head: h s = p s / γ liquid + v s 2 / 2 g (1) where. h s = suction head close to the impeller (m, in) p s = static pressure in the fluid close to the impeller (Pa (N/m 2), psi (lb/in 2)) These questions and answers about causes of and cures for high head pressure in an air conditioner or heat pump compressor motor were posted originally at …However, systems that pump low-pressure, high-temperature liquids are most likely to experience problems.

High suction pressure in a 404A system can be attributed to several factors. Overfeeding the evaporator, a dirty or blocked condenser, or an overcharged system can all lead to increased suction pressure. Additionally, if the walk-in cooler or freezer is frequently opened or has a high product load, it can ...To troubleshoot non-condensable issues, it is important to observe key performance indicators. If the system exhibits high head pressure, low suction pressure, poor cooling, increased sub-cooling, and high compression ratios, it may indicate the presence of non-condensables. Shutting off the system and equalizing pressures can provide valuable ...Figure 5 The effect of low level on the pump suction. The pump will still produce the same total head but the discharge head will go down. This means you may not have enough pressure to run your devices and you may need to consider getting a pump with a higher total head. ... After all if you have a high head, which means a high pressure ...we note (and you probably know better than I) that making sense of any refrigerant pressure reading requires also a note of the ambient temperature.
