Abstract
In an air conditioner which is a refrigeration apparatus, a heat source unit has a heat-source-side heat exchanger in which a refrigerant exchanges heat with heat source water. The heat-source-side heat exchanger includes a plurality of heat exchange sections, and has a heat exchange region whose size can be adjusted through changing the number of heat exchange sections into which the refrigerant flows. The heat source unit has a controller which can adjust the size of the heat exchange region of the heat-source-side heat exchanger based on a differential pressure index value. This can broaden the temperature range of the heat source water within which the heat source unit of the refrigeration apparatus is operable.
