Abstract: A distributed composite refrigeration system includes a multichannel heat exchanger and at least two refrigeration units. The at least two refrigeration units are connected to at least two indoor areas in one-to-one correspondences. Each refrigeration unit includes a refrigeration part, a heat exchange part, and a heat dissipation part. A refrigerant flows between the refrigeration part and the heat exchange part, an intermediate medium flows in the heat exchange part, and the refrigerant and the intermediate medium implement heat exchange at the heat exchange part. The heat exchange part delivers the intermediate medium obtained after heat exchange to the heat dissipation part and/or the multichannel heat exchanger for heat dissipation. The multichannel heat exchanger is thermally connected to an external pipe network, and the intermediate medium performs heat exchange with a heat carrying body in the external pipe network.

Abstract: A composite refrigeration system includes a refrigeration part, a heat dissipation part, a first pipeline, a second pipeline, and a refrigerant. The refrigeration part uses the refrigerant to cool air sent into indoor space, and the heat dissipation part is configured to perform heat dissipation on the refrigerant. In addition, in two heat dissipation modes, the heat exchanger may exchange heat between the refrigerant and a heat carrier in an external pipeline network to implement heat dissipation. The composite refrigeration system implements, by using the heat exchanger, a function of exchanging heat with the external pipeline network, so that heat generated during operation of the composite refrigeration system can be at least partially transferred to the heat carrier in the external pipeline network, to implement the energy recycle and reuse.
