REFRIGERATING AIR-CONDITIONING DEVICE

摘要

Disclosed is a refrigerating air-conditioning device that can simultaneously process air-conditioning loads, such as cooling loads and heating loads, and other refrigeration and freezing loads, and that enables provision of a stable heat source supply throughout the year. The refrigerating air-conditioning device (100) enables the use of cold energy stored in a primary side refrigerant as a refrigeration/freezing load by transferring same to a secondary-side refrigerant circulating in a freezing cycle (2) for refrigeration/freezing, via a first refrigerant-refrigerant heat exchanger (131), whilst continuing to enable the use of heat energy or cold energy stored in the primary-side refrigerant as an air-conditioning load via an indoor heat exchanger (118).
