✦ Synopsis
The depletion of ozone and the greenhouse e!ect a!ect strongly the way we design and optimize inverse cycles machines. This paper gives a history of these two new emerging constraints. Various ways to reduce ozone and greenhouse e!ects are reported (recycling, destruction, new #uids), but the most promising one seems to be redesigning the machines. Two main ways are possible: (i) new design alternatives (such as permanent gas machines, or absorption, adsorption con"gurations), or (ii) improving classical vapour compression con"gurations. We focus here on this last aspect, and propose two ways to optimize it: (a) by improving the HEX design from an ecological and energetic point of view (a criterion similar to the thermoeconomic one is proposed), and (b) to integrate the preceding optimization, to optimize the complete machine; this second step is complementary to the "rst one. Some examples are given to illustrate the proposal.
