Method for transferring heat between two or more media and system for carrying out said method

A system for producing heat transfer between two or more media in a closed circuit, with low energy consumption, for household, commercial or industrial use, capable of being used for producing heat transfer, comprising:

• a) a cylinder (1), which comprises in its interior at least one piston (2) which is joined to a plunger (27), the plunger (27) being moved alternatingly under the actuation of a directional control valve (29) which receives a hydraulic fluid from a hydraulic pump (32);
• b) at least one closed chamber (5) connected to the cylinder (1), said closed chamber (5) comprising at least one pipe (8), WHEREIN the thermal working fluid is compressed in said closed chamber (5), producing a change from the liquid to the solid state or vice versa or from a solid state to another solid state or vice versa;
• and
• c) a control system (11), in which the actuation of the directional control valve (29) is regulated according to the temperature and pressure obtained in the closed chamber (5), WHEREIN said heat transfer system further comprises:
• d) at least one heat exchanger (34), which is formed by the pipe (8);
• and
• e) ventilation ducts (31), which are situated at the outlet of the heat exchanger (34) and which achieves control of the cooled or heated fluid in the pipe (8).

A method for producing heat transfer between two or more media in a closed circuit, with low energy consumption, for household, commercial or industrial use, capable of being used for producing heat transfer, comprising:

• a) introducing a thermal working fluid into a closed chamber (5) connected to a cylinder (1), said closed chamber (5) comprising at least one secondary pipe (8);
• b) compressing the thermal working fluid in said closed chamber (5) by means of a cylinder (1), which comprises in its interior at least one piston (2) which is joined to a plunger (27), the plunger (27) being moved alternatingly under the actuation of a directional control valve (29), which receives a hydraulic fluid from a hydraulic pump (32);
• c) regulating the actuation of the directional control valve (29) with respect to the temperature and pressure obtained in the closed chamber (5) via a control unit (11), WHEREIN said method further comprises the steps of:
• d) producing the change of state of the thermal working fluid, from liquid to solid or vice versa or from a solid state to another solid state or vice versa by virtue of the pressure increase and in accordance with the phase diagram of each thermal working fluid, yielding or delivering heat to a heat exchanger (34) formed by the pipe (8) and yielding or delivering heat to ventilation ducts (31) situated at the outlet of the heat exchanger (34), thus achieving control of the cooled or heated fluid in the pipe (8);
• e) decompressing the thermal working fluid in said closed chamber (5) in order to re-induce the change of state by virtue of the pressure drop, in accordance with the phase diagram of each thermal working fluid;
• f) repeating step b) through step e) until the desired temperature is attained in the household, commercial or industrial environment.
