<p>The invention concerns a new heater comprising a tank for the refrigerant fluid (B, C), at least one compressor pump (E), at least one heat exchanger (G), at least one pressure reducing valve (H). The refrigerant fluid in the liquid phase is distributed on the bottom of the tank (B), while the refrigerant fluid in the gas phase is distributed in the upper part of the tank (C). The compressor (E) draws the refrigerant fluid in the gas phase from the upper part of the tank (C) and conveys it towards the heat exchanger (G). The compression of the refrigerant fluid in the heat exchanger (G) is obtained by placing a pressure reducing valve (H) in the outlet pipe of said heat exchanger (G). The fluid cooled by the heat exchanger (G), once it has passed beyond the valve (H), is saturated and compressed in a low pressure area and tends to become liquid again. Said refrigerant fluid is conveyed again towards the inside of the tank (B, C), from where it restarts its cycle.</p> |
