47、verse cycle and nonreverse cycle units, the conditions on the water(brine) side are given by the inlet and outlet water(brine) temperatures, possibly leading to different water(brine) flow rates in heating and cooling modes.The rating tests in heating mode also apply for units having evaporatively c
