Abstract:
The present invention provides a refrigeration electrical appliance, comprising a food preservation working fluid loop. The food preservation working fluid loop connects a hot-end heat exchanger, a cold-end food preservation heat exchanger, and a food preservation regenerator. A first pair of diverter valves and a hot-end storage device are connected to the food preservation working fluid loop. The hot-end storage device is located below one or both of the first pair of diverter valves. A freezing working fluid loop connects a cold-end freezing heat exchanger and a freezing regenerator. A second pair of diverter valves and a cold-end food preservation storage device are connected to the freezing working fluid loop. The cold-end food preservation storage device is located below one or both of the second pair of diverter valves. A liquid-liquid heat exchanger is also connected to the food preservation working fluid loop.
