Abstract:
A freezer that has use side heat exchangers of plural systems and where liquid side connection piping is integrated into one. In operation of 100% heat recovery not using an outdoor heat exchanger, a reverse flow prevention mechanism (37) for preventing a liquid refrigerant, flows out from an indoor heat exchanger (41), from flowing to a direction other than those to heat exchangers (45, 51) for refrigeration and freezing. This stabilizes the flow of refrigerant in a circuit even in a low outside temperature condition to prevent lowering of freezing capability.
