WebFeb 8, 2010 · Model is WSC 087. The suction superheat can not be controlled properly. When the chiller run at higher capacity (for example,70%), suction superheat is about 1 ℃, subcooling is about 4.5 ℃ When chiller run at lower capacity (<50%), suction superheat increases to 6 ℃, subcooling is 2.5 ℃. According to manufacture data, the rated suction ... WebMay 11, 2000 ·  Adjust the superheat of the valve to a slightly higher value. Attempting to control an evaporator near to or lower than 5°F operating superheat can exceed the sensing capability of most expansion valves and result in hunting and subsequent intermittent flooding.  If practical, move the bulb farther downstream on the suction line.
Web2. as the suction superheat rises, the discharge superheat rises 3. as a multi-stage compressor (not multi-circuit or multi-compressor system) unloads, the discharge superheat rises 4. as a compressor pumps less (due to leaking valves or higher than normal head pressure, etc) the discharge superheat rises 5. single stage scrolls tend to … WebSep 18, 2024 · You may also have a higher suction pressure due to a leaky discharge valve. This allows the discharge gas to sneak up into the compressor’s cylinder during the downstroke. Your suction pressure increases because the suction valve is being open during the part of the downstroke of the compressor. ... The settings for superheat ; …
