In order to reduce the dimensions and costs of a heat exchanger, while at the same time increasing its heat effectiveness, it is suggested to configure the heat exchanger such that a condenser side and an evaporator side of the heat exchanger are separated from each other by a barrier.

A compact heat exchanger assembly for a refrigeration system includes a heat rejection heat exchanger assembly and a heat absorption heat exchanger assembly. The heat rejection heat exchanger assembly includes a primary heat exchanger and a secondary heat exchanger. The primary heat exchanger has a tube bank extending between a first manifold and a second manifold. The tube bank being provided with at least one bend such that the primary heat exchanger has a generally curvilinear shape. The secondary heat exchanger is disposed between the first manifold and the second manifold.

In various implementations, a heat exchanger system may include one or more flow paths. At least one of the flow paths may be associated with more than one pass and/or fluid flow through the flow path may be restricted. A setting of the heat exchanger system may include associations between flow path(s) and/or pass(es). A setting for the heat exchanger system may be determined, and the heat exchanger system may be allowed to operate in the determined setting, in some implementations.
