2. Record the suction temperature, suction pressure,
suction pressure converted to temperature, and
superheat of each system below:
SYS 1 SYS 2 SYS 3 SYS 4
Suction Temp = ____ ____ ____ ____ kPa (PSIG)
Suction Press = ____ ____ ____ ____ °C
(°F)
Temp = ____ ____ ____ ____ °C
(°F)
Superheat = ____ ____ ____ ____ °C
(°F)
Proper subcooling and superheat will assure optimum
performance and reliability of the system. Checks should
always be made when commissioning a chiller, and on a
yearly basis.
LEAK CHECKING
q
1. Leak check compressors, fittings, and piping to
assure no leaks.
If the unit is functioning satisfactorily during the initial
operating period, no safeties trip and the compressors
load and unload to control water temperature, the chiller
is ready to be placed into operation.
