Embodiment Construction
[0079]In the following, preferred embodiments of the present invention will be described in detail with reference to the drawings.
[0080]FIG. 1 is a refrigerant circuit diagram of a refrigeration apparatus (1) according to an embodiment of the present invention. The refrigeration apparatus (1) is installed, for example, in a convenience store and provides cooling of a showcase used for cold storage, cooling of a showcase used for freeze storage, and cooling / heating of the store space.
[0081]The refrigeration apparatus (1) includes these units: an outdoor unit (heat source-side unit) (10), an indoor unit (second utilization-side unit) (20), a cold storage unit (first utilization-side unit) (30), and a freeze storage unit (first utilization-side unit) (40). These units (10, 20, 30, 40) are connected by a gas-side interunit piping line (51, 52) and a liquid-side interunit piping line (53, 54, 55) to constitute a refrigerant circuit (50) in which a vapor compression refrigeration cycle is...
