Description

The present invention relates to a heat exchanger and a heat exchange heating system for uniformly heating a room by radiant heat.

Thermal energy flows from high temperature to low temperature. This phenomenon is called heat transfer, and when the heat transfer is viewed microscopically, there are two modes in which the mechanism is clearly distinguished. One is heat conduction diffused by the propagation of heat energy, and the other is radiation (radiation) in which heat energy is transferred by electromagnetic waves.

Conventionally, a stove or a hot air heater has been used as a means of heating the room.
These heating means utilize heat conduction and convection heat to heat the interior space. However, in this method, the air around the heating device, which is a heat source, is warmed, and the air convection in the room to warm the indoor space. Therefore, the temperature difference between the vicinity of the heat source and the distance becomes large.

In addition, there is a method using radiant heat as another means for heating the room, and a typical heating means is floor heating. In the floor heating apparatus described in the prior art document 1, a base plate is arranged on a substrate forming a foundation via a heat insulating material, and a heat pipe is incorporated between the base plate and the floor material. Panels are arranged. The heat pipes are uniformly incorporated in the floor heating panel with a regular meandering pattern, and the hot water supplied from the hot water supply installed outdoors circulates in the heat pipes. ..

In this heating system, a space is provided in the heat pipe and the floor material, air convection is generated by warming the air joined to the heat pipe in the provided space, and heat is conducted to the floor material by convection heat transfer. Warm flooring produces radiant heat. In Prior Document 1, heat is radiated from the floor material warmed by convection heat transfer to the indoor space as described above, and heat conduction is also performed from the warmed floor material to the indoor air.

However, in the indoor heating system described above, since convection heat transfer is used, the temperature of the floor becomes uneven and it is difficult to use it as a heating means for uniformly heating the room. The room is warmed by heat conduction and heat radiation, but it is not enough to heat the room uniformly due to the temperature spots on the floor surface and the heat spots in the room due to heat transfer.

By the way, it is said that 75% of the heat transfer passing through the building is due to heat radiation. The heat transfer due to heat radiation to the floor, ceiling, and wall surfaces is 93%, 50 to 70%, and 65 to 80%, respectively, and the heat transfer due to heat conduction is 5 to 7 in any direction. It is said to be about%. Therefore, most of the heat transfer is due to heat radiation. Based on this, it is difficult to efficiently and uniformly heat the room only with a heating system using a heat exchanger, and it is necessary to equip the room space with a heat insulating mechanism for maintaining a warmed room temperature. be.

Further, FIG. 4 is a diagram schematically showing a cooling / heating system 300 in which a cooling function is added to the heating system 100 of the present embodiment. Further, FIG. 5 is a diagram showing a heat insulating mechanism of the heat radiating unit 50 of the present embodiment, and FIG. 6 is a diagram showing another heat insulating mechanism of the heat radiating unit 50 of the present embodiment.
As shown in FIG. 1, the heating system 100 according to the embodiment of the present invention is configured as follows.
That is, in the heating system 100 of the present invention, the heat exchange unit 10 for exchanging heat with the heat energy from the heating mechanism 20 by the circulation of the heat medium 14 and the heat energy from the heat exchange unit 10 are radiated at a predetermined place. The heat radiating unit 50 is connected to the heat radiating unit 50 via the circulation unit 60.
The heat exchange unit 10 is configured by accommodating the heat medium 14 in which the ceramic powder 13 is mixed with the ethylene glycol liquid 12 in the heat medium storage case 11 configured by laminating in multiple layers, and moreover, the heat medium of the heat exchange unit 10. 14 is configured to reciprocate with the heat radiation pipe 52 of the heat radiation unit 50 via the circulation unit 60.
Further, the heat medium storage case 11 is a flat case or a cylindrical case made of stainless steel or aluminum, and the heat medium is circulated inside.
Further, in the middle of the outward path of the circulation pipe, an expansion space tank 30 for releasing the thermal expansion of the heat medium is branched and connected.
Further, as shown in FIG. 4, in the heating / cooling system 300 of the present invention, the water-cooled heat exchange unit 80 for heat exchange by the cooling mechanism when the heat medium 14 is circulated, and the heat energy released by the water-cooled heat exchange unit 80. Is connected to a heat radiating unit 50 for absorbing heat at a predetermined place via a circulation unit 60.
The water-cooled heat exchange unit 80 includes a first open / close valve 83, a second open / close valve 88, a third open / close valve 89, and the first open / close valve 89, which are provided in the middle of the return path of the second circulation pipe 53 arranged in the circulation portion 60. A water temperature sensor 84 for opening the on-off valve 83 and the second on-off valve 88 to cool the heat medium 14 when the third on-off valve 89 is closed, and cooling water 85 according to the water temperature of the water temperature sensor 84. It is composed of a water temperature control board 86 for determining whether or not to spray on the ground surface, and a discharge pump 87 capable of spraying cooling water 85 on the ground surface according to the judgment of the water temperature control board 86.
Further, as shown in FIG. 5, the ceiling surface, the wall surface, and the floor surface of the heat radiating unit 50 are provided with a heat insulating material in which aluminum foil is laid on styrofoam .
Hereinafter, each component of the present invention will be described.

Since the heat medium storage case 11 is warmed by heat conduction from the outside, the contact area with the outside is expanded so that the heat from the outside can be absorbed as much as possible, and the temperature of the heat medium 14 inside is efficiently raised. It is preferable to have a shape suitable for forming, for example, a flat shape as shown in FIGS. 2 (a) and 2 (b), or a donut shape having a cylindrical shape and a hollowed-out center. Is preferable. Further, the heat medium storage case 11 is preferably made of a material that reflects far infrared rays generated from the heat medium 14 warmed in the heat medium storage case 11, and is made of, for example, stainless steel or aluminum. It is preferable to have.

Further, the ethylene glycol liquid 12 mixed with the ceramic powder 13 is enclosed in the heat medium storage case 11. The ethylene glycol liquid 12 has a characteristic that the specific heat is small and the temperature easily rises. Therefore, the fluidity of the ethylene glycol liquid 12 increases immediately after being warmed, convection occurs in the heat medium storage case 11, and the temperature of the heat medium 14 can be efficiently raised. Further, since the ethylene glycol liquid 12 has a low thermal conductivity, the heat loss due to the heat conduction is small. That is, it is shown that the temperature drop of the heat medium 14 when passing through the circulation unit 60 and the heat radiation unit 50 is not caused by heat conduction but by the action of heat radiation. From this, it is possible to heat the indoor space by heat radiation and uniformly warm the indoor space.

Since the ceramic powder 13 has a large specific heat, it has a large amount of heat and the temperature does not easily drop to a place where heat is radiated. Further, since the ceramic powder 13 has a high thermal conductivity, the amount of heat corresponding to the increased temperature can be propagated to the surrounding ethylene glycol liquid 12. Further, the ceramic powder 13 has a radiation wavelength ratio similar to that of the ethylene glycol liquid 12, and the heat loss released to the outside by repeatedly absorbing and radiating between the ethylene glycol liquid 12 and the ceramic powder 13. Is reduced as much as possible.
Further, the ceramic powder 13 is circulated by the circulation pump 40 to come into contact with the scale in the circulation path, and has an effect of preventing scale inside the pipe and the inside of the boiler.
Further, since the ceramic powder 13 has an emissivity close to that of a blackbody, the amount of far infrared rays emitted by heating and raising the temperature is larger than that of other substances, and has the effect of increasing the amount of far infrared rays in the room. .. The ceramic powder 13 is preferably a material having the above-mentioned characteristics, and is preferably composed of, for example, silicon carbide or zirconia.
Further, a part of the ethylene glycol liquid 12 is thermally decomposed as the temperature rises in the heat exchange section to generate water. Therefore, the moisture generated during heating gradually evaporates and diverges from the seam inside the pipe, and the moisture decreases from the heat medium 14. As a result, when the temperature of the ethylene glycol liquid 12 drops to room temperature, it loses its fluidity and becomes a gel state, and the circulation function deteriorates. However, by mixing the ceramic powder 13 with the ethylene glycol liquid 12, the thermal decomposition of the ethylene glycol liquid 12 is inhibited and the gelation of the ethylene glycol liquid 12 is reduced as much as possible.
Further, the ethylene glycol liquid 12 as the undiluted solution can suppress the thermal decomposition action by mixing the ceramic powder 13 and can suppress the change in the loss of the liquid. This makes it possible to realize a maintenance-free heat exchange heating system that does not require maintenance other than compensating for the loss due to gasification of about 3% every year.

The heating mechanism 20 is a mechanism for heating the heat medium storage case 11 by heat conduction, and is a heating mechanism using the combustion heat of city gas in the present embodiment. Any other heat source is acceptable.

The circulation unit 60 includes an expansion space tank 30, a circulation pump 40, a first circulation pipe 51, a second circulation pipe 53, a supply header 61, and a return header 62.

The expansion space tank 30 is a mechanism for relaxing and absorbing the thermal expansion of the heat medium 14 heated by the heating mechanism 20 in the heat exchange unit 10. By having the expansion space tank 30, damage to the circulation pump 40 and the first circulation pipe 51 due to the pressure increase due to the thermal expansion of the heat medium 14 is prevented, and the heating system fails at the start of use with the highest load. It is configured to prevent. Further, the gas generated by the thermal decomposition of the ethylene glycol liquid 12 is prevented from staying in the circulation round-trip path, and air biting does not occur.

Further, the circulation pump 40 is a pump used for the heat medium 14 to circulate in the reciprocating path between the heat exchange unit 10 and the heat radiation unit 50. By having the circulation pump 40, the flow velocity of the heat medium 14 circulating in the heating system 100 can be kept constant. By keeping the flow velocity of the heat medium 14 constant, the amount of heat applied from the heating mechanism 20 of the heat exchange unit 10 to the heat medium 14 can be kept constant. Therefore, the temperature of the heat medium 14 when discharged from the heat medium storage case 11 has a temperature suitable for heat radiation, and the amount of radiant heat transfer emitted when passing through the heat radiation pipe 52 can be kept constant. .. That is, the temperature distribution in the indoor space can be kept uniform.

The supply header 61 has a distribution mechanism for distributing the heat medium 14 heated by the heating mechanism 20 to a plurality of heat radiation pipes 52 arranged in the heat radiation unit 50. Therefore, the supply header 61 has the selectivity that the heat medium 14 can be circulated to the required portion, and the temperature drop due to heat radiation at the unnecessary portion can be prevented.

Further, the return header 62 has an aggregation mechanism for consolidating the heat medium 14 distributed to the plurality of heat dissipation pipes 52 by the heat dissipation unit 50 into one pipe. By consolidating the heat medium 14 in the return header 62, it is possible to prevent a temperature drop in a place where heat transfer is unnecessary, and it is possible to minimize overheating in the heat exchange unit 10.

The first circulation pipe 51 is a circulation path from the heat exchange unit 10 to the supply header 61 via the circulation pump 40. The first circulation pipe 51 preferably has a material and a flow path diameter that do not easily lower the temperature until it reaches the heat radiating portion 50. For example, the first circulation pipe 51 has a low thermal conductivity like a polybuden pipe and has a pipe inner diameter of 21.2 mm or more. Is preferable.

Further, the second circulation pipe 53 is a circulation path from the return header 62 to the heat exchange unit 10. Like the first circulation pipe 51, the second circulation pipe 53 is preferably made of a material that does not easily lower the temperature and has a flow path diameter. Is preferable.

The heat radiating unit 50 is composed of a plurality of heat radiating pipes 52. As the heat radiating pipe 52, it is preferable to use a thin tube for uniformly heating the entire room, and in this embodiment, for example, a thin tube having an inner diameter of 9.8 mm is adopted. Therefore, the bending radius at the time of arranging the floor surface can be reduced, and the heat radiating pipe 52 can be spread over the entire floor surface without any gap. Further, by laying the entire floor surface without gaps, it is possible to provide a sufficient radiation area for warming the indoor space.

With such a configuration, the loss of the amount of heat acquired in the heat exchange section is reduced as much as possible so that the heat is radiated to the heat dissipation part and sufficient heat radiation is possible to warm the room at the predetermined place. It is possible to provide a heat exchanger having high heat exchange efficiency and to provide a heating system that uniformly heats an indoor space by heat radiation by far infrared radiation.
The heat exchange unit 10 converts the electromagnetic waves in the near-infrared region radiated from the warmed ethylene glycol liquid 12 and the ceramic powder 13 into far-infrared rays by reflecting and refracting them in the heat medium storage case 11. It is possible to radiate a large amount of far infrared rays as compared with conventional heat exchangers.

As shown in FIG. 4, the configuration of the heating system 100 is such that the water-cooled heat exchange unit 80 is attached to the second circulation pipe 53 in the circulation unit 60 between the heat radiation unit 50 and the heat exchange unit 10 constituting the heating system 100. By providing it, the air-conditioning route can be selected by the on-off valve, and the air-conditioning system 300 can be used.

It is composed of a valve 89.

In the branch supply header 81 and the branch return header 82, when the heat medium 14 is cooled, the fluidity decreases and plays a role of alleviating the pressure rise at a specific location, and the damage to the piping and the failure of the circulation pump are possible. Can be reduced.

The first on-off valve 83, the second on-off valve 88, and the third on-off valve 89 can be selected from two states, an open state and a closed state, and depending on the open state of each valve, the valve goes through underground or via. You can choose not to. In the summer, the first on-off valve 83 and the second on-off valve 88 are opened, and the third on-off valve 89 is closed to cool the heat medium 14 with groundwater, absorb room temperature as a refrigerant body, and lower the room temperature. Further, by closing the first on-off valve 83 and the second on-off valve 88 and opening the third on-off valve 89, the heat medium 14 can be heated via the heat exchanger without going underground, and the heating can be performed. It can be used as a system 100.

The cold heat exchange tank 85 is a tank for storing cooling water provided with cooling water for cooling the third circulation pipe 54 for circulating the heat medium 14, the fourth circulation pipe 55, and the circulating heat medium 14. be.

The discharge pump 87 operates in conjunction with the water temperature sensor 84 installed in the cold heat exchange tank 85. The judgment of whether or not the discharge pump 87 can be operated is controlled by the water temperature control panel 86, and when the water temperature sensor 84 determines that the water temperature exceeds the reference water temperature, the discharge pump 87 operates and sprays the water whose temperature has risen on the ground surface. do.

The wall joist plate 231 is arranged between the wall concrete 221 and the wall heat insulating material 72, and has a certain height to form an air layer 233 between the two. By providing the air layer 233, the amount of heat contained in the wall concrete 221 is prevented from being transferred to the wall heat insulating material 72.

The wall heat insulating material 72 is configured by pasting aluminum foil on styrofoam, and the aluminum foil is arranged on the indoor space R side and styrofoam is arranged on the outdoor side. As a result, the radiant heat from the indoor space R is retained without being released to the outside, and the heat conduction with the outside is blocked by the air contained in the styrofoam, so that the heat transfer between the room and the outside can be reduced. A wall plate 211 is arranged inside the wall heat insulating material 72.

The ceiling surface C is sequentially arranged from the outside in the order of the ceiling concrete 222, the air layer 230, the ceiling joist plate 232, the ceiling heat insulating material 71, and the ceiling plate 212.
