A method for heating or cooling an environment, with low energy consumption, for domestic, commercial, or industrial use, wherein the method comprises the following steps:
- a) insert a thermal working fluid into a closed chamber connected to a force unit (10), wherein the closed chamber comprises at least one tube (12) joined with at least one radiator (8a, 8b);
- b) regulate an operation of the directional control valve (29) according to the temperature and pressure obtained from the closed chamber, through a control unit (11);
- c) compress the thermal working fluid according to the phase diagram of the thermal working fluid, to increase the temperature of that thermal working fluid within a side of the closed chamber to transfer heat to a second heat transfer circuit (93) through some valves (37as, 37ai, 37bs, 37bi) and decompress the thermal working fluid within an opposite side of the closed chamber to cool the thermal working fluid, according to the phase diagram of the thermal working fluid to decrease the temperature of the thermal working fluid within that closed chamber, to absorb heat from the first heat transfer circuit (92) through some valves (37as, 37ai, 37bs, 37bi) through at least one force unit (10);
- d) produce 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, due to the increase in pressure, according to the phase diagram of the thermal working fluid;
- and
- e) balance the temperatures of the two closed chambers (34a, 34b) through the recirculation of a heat transfer fluid which is guided by some valves (81ai, 81bs, 81bi;
- 81as) operated by a control unit (11), while the thermal working fluid is kept compressed within that closed chamber;
- f) decrease the temperature of the compressed side of the closed chamber (34) until said temperature is lower than the temperature of the opposite side of the closed chamber (34) that was not compressed in the prior step, wherein some valves (37as, 37ai, 37bs, 37bi) allow the heat transfer fluid of the first heat transfer circuit (92) to pass through a first heat exchanger (41), and the valves (37as, 37ai, 37bs, 37bi) allow for the temperature increase of the decompressed side of the closed chamber (34) until said temperature is higher than the temperature of the opposite side of the closed chamber (34) which was compressed in the prior step, through a fluid of the second heat transfer circuit (93) which passes through a second heat exchanger (42), wherein the valves (37as, 37ai, 37bs, 37bi) are operated by a control unit (11);
- g) decompress the thermal working fluid within that closed chamber, from the side that was initially compressed, and compress the thermal working fluid from the other closed chamber through the activation of a directional control valve (29), without activating the valves (37as, 37ai, 37bs, 37bi), to once again provoke the change of state due to the low pressure and temperature, according to the phase diagram of the thermal working fluid;
- h) repeat through g) until the desired stages e) temperature is reached in the first (41) and second (42) heat exchangers.
