The RTU manufacturer assisted with this project by providing
their test data for this unit, and that data served as a basis for the
RTU setup and operation during this study. Since the original air-torefrigerant
condensers were replaced with water-cooled, brazedplate
heat exchangers, the unit was charged with refrigerant such
that the liquid line temperature and pressure matched the manufacturer's
test data, which allowed the RTU's evaporator portion to
operate as it would in a typical installation
