Abstract

PROBLEM TO BE SOLVED: To contrive no noise generation and simplification of a piping structure, by providing a condensation device wherein supplied vapor is liquefied and a working liquid reciprocally moves and a plurality of heat radiating parts liquidly communicating with the working liquid for storing the working liquid without using a pump and a compressor. SOLUTION: When an evaporator 22 is heated by a burner 25, a working liquid 12 is heated, evaporated and introduced into a condenser 1 via a pipe 7 to push the working liquid 12 within a cylinder 2 downward. Volume of a heating space 6 increases to exceed a heat insulation part 24, and, when introduced to a condensation space 5, the working liquid in gas phase is condensed. By this liquefaction, high temperature of the working liquid 12 in gas phase raises temperature of the liquid 12 in a liquid tank 4 and a condensation space 15. And, the working liquid 12 in the cylinder 2 and a coil device 4 is heated. That is, high temperature of the liquid 12 is dissipated to the working liquid 12 and temperature of the working liquid 12 is raised and the working liquid 12 flows into the coil device 4. Thus, temperature around each heat radiating part 18 heated by the working liquid 12 is diffused into a room by rotation of a motor driven fan 21 for heating.

[0003]

However, when a pump or a compressor is used, noise during operation becomes unavoidable, and there is a case where the use of a heating device at midnight must be neglected. Further, two pipes have to be provided between the indoor unit and the outdoor unit for the circulation of the working medium described above, so that the structure is inevitably complicated.

[0004] Therefore, an object of the present invention is to provide a heating device in which such a problem is eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings.

(First Embodiment) In FIG. 1, the heating device includes an evaporator 22. The evaporator 22 is the working fluid 1
The working fluid 12 is changed to a gas phase by heating the bottom of the cylindrical body 10 storing 2 with the burner 25, that is, the steam of the working fluid 12 is generated. And evaporator 2
The steam generated in 2 is supplied to the upper side of the cylinder 2 of the condenser 1 via a conduit 7 formed adiabatically.

The lower side of the cylinder 2 of the condenser 1 is in fluid communication with the working fluid 12 stored in the plurality of heat radiating portions 18 of the coil device 4. Thus, the working fluid 12 in the heat radiating section 18 is in fluid communication with the tank 20 that is opened to the atmosphere via the pipe 19. Due to this opening to the atmosphere, reciprocation of the working fluid 12 described later is realized.

A heating section 3 and a condensing section 5 are formed on the upper and lower sides of the cylinder 2, respectively. Then, the heating unit 3
A heat insulating section 24 is located between the heat exchanger and the condenser section 5 to prevent heat transfer between them.

When the evaporator 22 is heated by the burner 25, the working fluid 12 is heated and evaporated. However, when the volume of the working fluid 12 in the gas phase increases, the condensing device 1 passes through the conduit 7.
, The hydraulic fluid 12 inside the cylinder 2 is pushed down to bring the state shown in the figure. Under this state, the upper side and the lower side of the liquid surface 13 of the working fluid 12 become the heating space 6 and the condensing space 5, respectively. The volume of the heating space 6 increases and the heat insulating portion 24
, The temperature of the condensing space 5 is lower than the temperature of the heating unit 3, so that the gas-phase working fluid 12 is condensed and liquefied.

With the liquefaction, the high temperature of the gaseous working liquid 12 is increased by the liquid 12 in the condensing space 15 and the liquid tank 4.
Increase the temperature of At the same time, heating space 6 accompanying liquefaction
Decreases the volume of the condensing space 15, that is, raises the liquid level 13 of the working fluid 12. Since the working fluid 12 in the high-temperature and gaseous phase is continuously supplied into the cylinder 2 through the conduit 7, the rising and falling of the liquid level 13 is repeated. In the process of reciprocating up and down, heat is applied to the working fluid 12 in the cylinder 2 and the coil 4. That is, the high temperature of the condensed liquid 12 is reliably radiated to the working fluid 12 in the liquid tank 4, and as a result, the temperature of the working fluid 12 rises.

When the hydraulic fluid 12 descends, the left one-way valve 16 opens while the right one-way valve 17 is closed. On the other hand, when the hydraulic fluid 12 rises, the left one-way valve 1
Under the state where 6 is closed, the right one-way valve 17 is opened.
Thus, the working fluid 12 flows in the coiling device 4 in the direction of the arrow. Then, the temperature around each heat radiating section 18 heated by the flowing working fluid 12 is diffused into the room by the rotation of the electric fan 21 to perform heating.

An auxiliary tank 33 for appropriately replenishing the working fluid into the cylinder 10 of the evaporator 22 is provided. The space above the liquid level in the auxiliary tank 33 is
Is connected to the evaporating space 14 in the cylindrical body 10 of the evaporator 22. The bottom of the auxiliary tank 33 communicates with the bottom of the cylinder 10 via the conduit 9. By employing such communication, when the liquid level in the cylinder 10 of the evaporator 22 decreases, the hydraulic fluid in the auxiliary tank 33 is refilled into the cylinder 10 (the principle of the communication pipe).

Further, the electric fan 21 can be removed and used as a panel heater for heating by natural convection. Furthermore, if the electric fan 21 is eliminated and a piping network is used instead of the coil device 4, it can be similarly used as a floor heating device that performs heating by natural convection.

When the supply of heat from the burner 25 is stopped, the temperature of the steam generator 22, the conduit 7, and the cylinder 2 drops, and
All of the gas-phase working fluid 12 existing inside is liquefied and returns to the initial state.

Only one pipe 7 is required between the steam generator 22 and the condenser 1, and the structure is simplified. Not only that, since the steam has an ascending characteristic, the heating device can be easily installed on the floor by installing the steam generator 22 and the condenser 1 on the lower floor and the upper floor, respectively.

(Second Embodiment) In FIG. 2, the heating device has an evaporator 22. The evaporator 22 is the working fluid 1
By heating the periphery of the cylindrical body 10 storing 2 with the heater 55, the working fluid 12 is changed to the gas phase, that is, the vapor of the working fluid 12 is generated. And evaporator 2
The steam generated in 2 is supplied to the upper side of the cylinder 2 of the condenser 1 via a conduit 7 formed adiabatically.

The lower side of the cylinder 2 of the condenser 1 extends into the internal space of the main body 54 formed of a heat insulating material, and is in fluid communication with the working fluid 12 stored in the plurality of heat radiating portions 18. . Thus, the upper side of each heat radiating portion 18 is open to the atmosphere, and the cylindrical body 2 and the heat radiating portion 18 are arranged in a matrix as a whole in plan view. The opening to the atmosphere enables the reciprocating movement of the working fluid 12 described later.

On the bottom side of the main body 54, a discharge space 55 located below the cylindrical body 2 and each heat radiating portion 18 is formed.
The hydraulic fluid 12 overflowing from each heat radiating section 18 is stored in an external tank (not shown) via a discharge space 55 and a discharge port 56.

The upper part of the cylindrical body 2, that is, the part where the main body 54 protrudes (the lower part, that is, the part immersed in the main body 54).
Is formed with a heating section 3 (condensing section 5). Thus, a heat insulating section (not shown) is located between the heating section 3 and the condenser section 5 to prevent heat transfer between the two.

When the cylinder 12 of the evaporator 22 is heated by the heater 55, the working fluid 12 is heated and evaporated. However, when the volume of the working fluid 12 in the gas phase increases, the working fluid 12 is condensed via the conduit 7. 1 and depresses the hydraulic fluid 12 inside the cylinder 2,
The condition shown is brought. Under this state, the upper side and the lower side of the liquid level 13 of the working fluid 12 are respectively in the heating space 6.
And the condensing space 15. When the volume of the heating space 6 increases and reaches the condensing section 5 beyond the heat insulating section, the temperature of the condensing section 5 is lower than the temperature of the heating section 3, so that the gas-phase working fluid 12 is condensed and liquefied.

With the liquefaction, the high temperature of the gaseous working fluid 12 causes the temperature of the working fluid 12 in the condensing space 15 and the heat radiating section 18 to rise. At the same time, a decrease in the volume of the heating space 6 due to liquefaction causes an increase in the volume of the condensation space 15, that is, an increase in the liquid level 13 of the working fluid 12. Thus, in the cylinder 2 via the conduit 7, the land-connected and high-temperature gas-phase hydraulic fluid 1 is placed.
2 is continuously supplied, the liquid level 13 is repeatedly raised and lowered, and in the process of the reciprocating up and down movement of the liquid level 13, heat is applied to the working fluid 12 in the cylinder 2 and the heat radiating portion 18. Will be added. That is, the condensed liquid 12
Is reliably radiated to the working fluid 12 in the heat radiating section 18, and as a result, the temperature of the working fluid 12 rises.

Since the temperature of the working fluid 12 in the heat radiating section 18 rises in this way, the temperature around the heat radiating section 18 also rises. The electric fan 21 is disposed at an exhaust port 58 formed on the upper left side of the main body 54, and when the electric fan 21 rotates, air flows from an intake port 59 formed at a right intermediate portion of the main body 54. , And this air is exhausted out of the main body 54 through the exhaust port 58. This air is heated by the heat radiating portions 18 heated by the reciprocating hydraulic fluid 12 while passing through the main body 54, diffused into the room, and heats the room.

An auxiliary tank 33 for appropriately replenishing the working fluid into the cylinder 10 of the evaporator 22 is provided. The space above the liquid level in the auxiliary tank 33 is
Is connected to the evaporating space 14 in the cylindrical body 10 of the evaporator 22. The bottom of the auxiliary tank 33 communicates with the bottom of the cylinder 10 via the conduit 9. By employing such communication, when the liquid level in the cylinder 10 of the evaporator 22 decreases, the hydraulic fluid in the auxiliary tank 33 is refilled into the cylinder 10 (the principle of the communication pipe).

The cylinder 10 constituting the evaporator 22 is
The heater 55, the conduit 9, and the auxiliary tank 33 are buried in a housing 52 made of a heat insulating material to form an electric boiler.

When the supply of heat from the heater 52 to the cylinder 10 is stopped, the temperature of the steam generator 22, the conduit 7, and the cylinder 2 is reduced, and the gas-phase working fluid 12 existing inside these is liquefied, and the initial state is reduced. Returns to the state.

Only one pipe 7 is required between the steam generator 22 and the condenser 1, and the structure is simplified. Not only that, since the steam has an ascending characteristic, the heating device can be easily installed on the floor by installing the steam generator 22 and the condenser 1 on the lower floor and the upper floor, respectively.
