REFRIGERANT CHARGE
The correct system R-22 charge is shown on the unit
rating plate. Optimum unit performance will occur with
a refrigerant charge resulting in a suction line
temperature (6 inches from compressor) as shown in the
Table 7.
rating plate. Optimum unit performance will occur with
a refrigerant charge resulting in a suction line
temperature (6 inches from compressor) as shown in the
Table 7.
The suction line temperatures in Table 7 are based upon
80ºF dry bulb/67 degrees F wet bulb (50 percent R.H.)
temperature and rated airflow across the evaporator
during cooling cycle.
