| 摘要 |
<p>The invention concerns a heat energy recovery system consisting of an external reversible exchanger (EA), a single compressor or at least two compressors one of which is a main compressor (CP) and at least a secondary compressor (CS) used as spare forming part of a refrigerating circuit comprising as loads several staged exchangers (ES1, ES2, ES3) and one of which is a main exchanger (EP) for domestic water and at least a reversible secondary exchanger (ES), and between the exchangers (ES1, ES2, ES3) and the external reversible exchanger (EA) an expansion and separation unit (BDS) with controlled thermostatic expansion devices and phase separator (S). Various sensors, remote-controlled valves and circuits optimise the operation and regulation.</p> |
