| 摘要 |
<p>The invention relates to a thermodynamic device (1, 10) for heating and/or air-conditioning a space, comprising a main cooling fluid circuit (2) provided with at least one compressor (3) arranged to increase the pressure and, consequently, the temperature of the cooling fluid in the gaseous state and one condenser (4) arranged to discharge, to an external circuit (5), at least part of the thermal energy absorbed by the cooling fluid which passes from the gaseous state to the liquid state. The invention is characterised in that the thermodynamic device (1, 10) is housed in a closed and sealed casing and in that it comprises an expansion chamber (6) which is disposed between the aforementioned condenser (4) and compressor (3) and which is arranged to expand the cooling fluid instantaneously such that it passes instantaneously from the high-pressure liquid state to a low-pressure gaseous state, said expansion chamber (6) being connected to a suction port (30) of the compressor (3) via a return duct (7) having a decreasing transverse dimension so as to gradually compress the previously expanded cooling fluid by heating same, such that the thermodynamic device (1, 10) operates independently, without an external source for collecting heat.</p> |
