The present invention relates to an electric circulating water heating system for use in domestic heating.

Various types of conventional circulating water heating systems are known for use in domestic heating. 7 shows an example 1 of a conventional system and FIG. 8 shows an example 2 of a conventional system.

Example 1 of a conventional system (FIG. 7) is a typical water heating system disclosed in Non-Patent Document 1, where FIG. 7 (A) is a schematic diagram of a heating system, FIG. 7 (B) is a front view of a radiator, and FIG. 7 (C) - side view of the radiator.

More specifically, in the case of Example 1 of the conventional system (FIG. 7), a water boiler 100 comprising a pressure gauge 103, a safety outlet valve 106, a water inlet 101, and a drain outlet 102 is heated by electricity, kerosene, gas, etc. , and hot water heated in the boiler is transferred to the HR radiator located in individual living rooms through the piping system P and the outlet side collector 107 for heating the interior, while hot water from individual radiators HR returns expands into the water boiler 100 through a conduit P and a return side collector 108 for reheating. Circulation pump 104, closed expansion tank 105, ventilation valve 106, manifolds 108, etc. are located in one functional block of hot water circulation, while the ventilation valve Va, thermostatic valve Vt, and the hot water inlet / outlet valve V are located in individual HR radiators.

In addition, to perform water filling and air removal in example 1 of a conventional system (Fig. 7), a heat pipe is additionally provided by means of a pipe extending upward with a slope of 1/100 from the boiler 100, and air is removed at the end of the pipe, where the valve V hot water supply / discharge directed to the water heating boiler 100 is opened to actuate the circulation pump 104, so that water is filled and air is removed for each group of pipelines branching to lecturers, 107, 108, and each radiator. For each radiator, the outlet side of the water supply pump having a water tank is connected to one shut-off valve located under each radiator, while the hose on the return side is connected to another shut-off valve, then the water supply pump is activated, thereby forcing water circulate inside each radiator several times, and leave the air through the ventilation means that the radiator is equipped with, thereby filling it with water.

Further, example 2 of a conventional system (Fig. 8) relates to an electric water heating unit EHR described in Patent Document 1 and shown in Fig. 8. An EHR electric water heating unit is a heating unit in which a plurality of radiating fins 202 are located on an outer peripheral surface of a straight heat copper pipe 201, a jacketed heating device 204 is located in a heating chamber 203 inside the heat copper pipe so that it essentially goes along the entire length of the heat copper pipe 201, while the heating chamber 203 is filled with an aqueous solution 205, the heat pipe 206 of the expansion chamber moves away from the heating th chamber 203 through a curved tubular section 207, thereby providing an expansion chamber 208 having a pressure relief valve 209 located at its end, with inert gas being introduced into the expansion chamber 208, thereby reducing the size of the heating unit as a whole, and the expected initial increase in radiation by heating the radiating ribs 202 will occur in a short time.

Patent Document 1: JP 6 - 18813 Y

Non-Patent Document 1: Precautions for design, installation, and operation ", and" Operational Instructions for Thermo-Panel "," Morinaga Hot-water Panel Heating Technical Literature ", Prospectus (No. 0402 - 5C - dB) of Morinaga Engineering Co. , Ltd.

The water heating circulation system described in Example 1 of the conventional system (FIG. 7A) comprises a water boiler 100 having a safety outlet valve, a pressure gauge, a drain valve and a water shut-off valve, a closed expansion tank 105 having a safety outlet valve, headers 107 , 108 exit and return sides, a hot water circulation pump 104, an air separation device 110 located between the boiler and a hot water circulation pump, a group of HR radiators, each the radiator has a shut-off valve for water supply, pipes P of the piping system for connection between the respective blocks, and corresponding valves. Since the boiler room, equipped in the building, is connected to radiators in the respective rooms using a piping system installed under the floor, in the wall and in the ceiling, respectively, this circulation water heating system has the following problems.

(A) When the water heating circulation system ages and wears out, enough rust accumulates on the metal panels (radiator) and in the piping system to stop the circulation of hot water and an emergency situation, such as water leakage, thereby polluting the floor, wall, ceiling buildings, however, during restoration or repair, restoration will be time consuming and expensive due to the use of an integrated piping system.

(B) If the circulation pump in the system, etc. breaks down, this will stop the heating for the system as a whole, and during the repair of equipment, its replacement, etc. there is a need for reworking the piping system, which includes a change in the design of the boiler body.

(B) As the piping system moves away from the boiler to the respective radiators, there will be more heat loss due to heat generation inside the hot water transmission paths.

(D) Since the radiator is equipped with an internal ventilation valve, shut-off valves for water supply / drain used during maintenance, etc., containing a thermostat protruding from them, the appearance of the radiator deteriorates.

In addition, the floor height in the building has recently become less, due to the cost of construction, the ceiling height of the room can be different for different rooms, and it becomes difficult to provide a piping system for heating with the required slope due to intersection with water supply / drain pipes or ventilation pipes, resulting in a reverse slope, or step, so it becomes important to place the ventilation valves in suitable places, and therefore the installation of the piping system is interrupted due to the presence of ventilation valves, thereby creating problems related to manufacturability and cost.

In addition, filling the system with water and removing air from it is carried out for radiators, as well as pipes of the corresponding subsystems branched out with the help of corresponding collectors, in such a way that water and air move even further from the boiler after opening the water valve of the water valve, however there are sections of the piping system where air cannot be removed due to the presence of a step, and air removal becomes difficult, and it is necessary to carry out the removal ozduha / water filling for all radiators, and for each separately. Until the air in the system with water is replaced correctly, the circulation of water in the system stops due to the air present in the piping system, and there is a need to carry out the air removal / filling work again, so there is a problem that the removal air should be produced every 3-5 years, depending on the method of constructing the piping system of heat pipes.

In the case of the electric water heating unit described in Example 2 of the conventional system (Fig. 8), the relative size of the radiating unit in comparison with the total volume of the heating unit is small, the aqueous solution in the enclosed heating device 204 simply heats up, and hot water does not circulate so that local temperature spots appear and the amount of heat generated will be small.

In addition, since heat generation for the heating device occurs in this case due to natural convection, the electric water heating unit is prone to the appearance of temperature spots in the form of a heat generation area.

In addition, the on / off control by the thermostat becomes abrupt, so that the heat generation is small compared to the amount of electric heating.

The technical task of the present invention is to solve the problems inherent in examples 1 and 2 of conventional systems, respectively, in whole or in part. For this, a new electric water circulation heating system is proposed, in which the radiating unit and the heating and hot water circulation unit, inside the same radiator, are separated from each other and used as a pair, and the electric water heating circulation system according to the invention can provide ease of maintenance and can conveniently adapt even when repairing a building.

The present invention relates to an electric water heating circulating system, which is an electrically heated water heating circulating system, comprising one unit from a radiator 8, said radiator being a radiator with hot water circulation and having an inlet 8S for supplying water and an outlet 8R for outputting water , one block of a monoblock heating device 1 in the form of a square cylinder, placed in such a way as to ensure the operation of one block of the radiator 8, in which a pressurized air separation tank 2, a circulation pump 3, and tubular heaters 4 are connected to each other by a piping system, a T-shaped connection 7A having a check valve 6C, and a T-shaped connection 7 having a check valves 6B, 6A sequentially inside the path of the piping system, the outlet pipe P _{6 '} departs from the T-shaped connection 7A, and the auxiliary tank 2' is located on the end of the outlet pipe P _{6 '} extending from the piping system P ₆ , thereby providing a hot circulation function water in the monoblock heating device 1, and the monoblock heating device 1 is connected to the radiator 8 using the pipe S of the outlet side and pipe R of the return side.

In this case, a new pressurized air separation tank 2 functions as an expansion tank 105 and an air separation device 110 in Example 1 of a conventional system (FIG. 7), and the volume of the pressurized air separation tank 2 can be determined based on the amount of water, which will flow in the heating system at room temperature, the amount of water when it is heated, and the volume of air that is separated.

In addition, the auxiliary pressurized tank 2 ′ enhances the function of the pressurized air separation tank 2 as the pressurized tank, and it may be a pressurized tank configured to be housed in a compact one-piece heating device 1. If the auxiliary works under pressure tank 2 'is a component that is identical in quality and shape to the pressurized air separation tank 2, this will be an advantage from the point of view of truing and the cost of a monoblock heating device.

In addition, through the use of an auxiliary pressure tank 2 ′, the internal pressure of the system can be absorbed even with an increase in thermal power (for example, from 1 kW to 3 kW), thereby providing a safe system.

In addition, the circulation pump 3, the tubular heater 4, check valves 6A, 6B, 6C and T-joints 7, 7A, which are part of the monoblock heating device 1, can be formed by conventional components, and the circulation pump 3 can be a conventional electromagnetic a pump made of synthetic rubber, or a conventional metal circulation pump, a tubular heater 4 can be formed by several SC-heaters (trade name) to generate a thermal power of 1 kW, having mi excellent energy-saving characteristics, manufactured by Netsusho Kabushiki Kaisha, and a pipe for piping system can be a tube made from conventional ethylene-propylene rubber which has excellent characteristics in durability, heat resistance, solvent resistance.

In addition, the monoblock heating device 1 combines the hot water circulation function in the system of example 1 of the conventional system (Fig. 7) in one unit, and the monoblock heating device 1 can be located longitudinally on the side surface of the radiator 8 or horizontally below the radiator 8, that is, it can be made with the possibility of its use in both vertical and horizontal position. In a heating system with a heat output range from 1 kW to 3 kW, the monoblock heating device 1 has the shape of a square cylinder and a small box, typically width L1 180 mm, depth W1 160 mm and height h1 590 mm. In addition, the radiator 8 may be any type of hot water circulation radiator, for example, it may be a metal panel (product name thermal panel) manufactured by Morinaga Engineering Co., Ltd. or a plastic radiator described in JP 2001 -116475A.

Further, in the heating system according to the present invention, one block of the monoblock heating device 1 is positioned so as to ensure the operation of one block of the radiator 8, so that even if one block of the monoblock heating device 1 fails, the other monoblock heating devices 1 and the corresponding radiators 8 will be in working condition, and therefore it is possible to avoid the case of a malfunction of the heating system in all rooms of the building, thereby preventing the occurrence of a situation in which captive in a residential part of the building to a complete stop.

In addition, the pressure of the pressurized tank 2 of the air separation can be supplemented by an auxiliary pressurized tank 2 ', and even if the internal pressure of the system increases, it is possible to provide a safe heating system without an emergency by working together under the pressure of the tank 2 of the air separation and auxiliary pressure tank 2 '.

In addition, in the heating system according to the present invention, since the monoblock heating device 1 including the heater can be located next to the radiator 8, there is no heat loss caused by heat from the piping system in the flow path from the heating device (boiler) to the radiator, as in example 1 of a conventional system (Fig. 7), and accordingly, for example, if heat is generated in pipelines inside and outside the monoblock heating device 1, this will be heat generation in the room y, with the result that there is no heat loss, in fact it is heating the heat.

In addition, since the radiator 8 is a radiator with hot water circulation, heating can be carried out without the occurrence of temperature spots to generate heat, and the respective radiators themselves can produce heat through heating by separate and independent work performed in the respective monoblock heating devices 1, so that it is possible to carry out the heating process as required without causing heat loss.

In addition, since the radiator 8 does not have protrusions, such as a thermostatic valve Vt, a ventilation valve Va, a shutter valve V, as in example 1 of a conventional system (Fig. 7), it is possible to provide an indoor heating system that is safe and has good appearance.

Additionally, since there is no piping system under the floor, in the wall, on the ceiling, etc., the heating system can be placed in a simple and flexible way in the necessary places, so that even if there is a leak of water from the radiator 8 or one-piece heating device 1 , this will be visible to the naked eye, as a result, an emergency situation of large pollution will not occur.

In addition, when upgrading a conventional heating system during a building repair, an existing circulation heating system can be easily upgraded to a heating system according to the present invention simply by placing a monolithic heating device 1 according to the invention next to an existing circulation type radiator, while leaving the old piping system located under the floor, in the wall, etc., unchanged.

In addition, in the system according to the present invention, which is the main requirement, as, for example, shown in FIG. 3, a T-connection 7A having a check valve 6C and a T-connection 7 having a check valve 6B and a check valve 6A are arranged sequentially one after another inside the pipe of the monolithic heating device 1, wherein the outlet pipe P _{6 '} departs from the T-shaped connection 7A, and the auxiliary pressure tank 2' is connected to the end part of the outlet pipe P _{6 '} .

In this case, the outlet pipe P _{6 '} may be a rubber pipe 5A, like a pipe pipe whose distal end is bent upward, the end of the base of the outlet pipe P _{6' is} connected to a T-shaped connection, and its end part is connected to the connecting pipe J1 of the lower surface auxiliary pressure tank 2 'in such a way that both the end of the base and the end of the outlet pipe P _{6' are} clamped using a hose clamp 5B.

Accordingly, while the system is filling with water, the outlet side pipe S and the return side pipe R of the monoblock heating device 1 are connected to the radiator 8, then, as shown in FIG. 3 (D), the T-check valve 6A 7 is connected to the tap (a) of tap water via a pressure hose (c), and the end of the transparent hose (d) connected to the check valve 6C of the T-shaped connection 7A is inserted into the bucket (b), while the transparent hose (d) rises to the height (e) of lifting at an intermediate point between at reflux valve 6C and a bucket (b) so that the check valve 6B is closed, while the check valves 6A to 6C are opened, thereby infusing flow w water by tap water pressure from the tap (a) in the path of system flow.

In this case, the check valve 6A and the tap (a) are closed at the stage when the air foam is discharged into the bucket (b), while the flow of water inside the transparent hose (d) is observed with the naked eye, and the pressure of the water poured into the system can be established by opening the non-return valve 6B and closing the non-return valve 6C, while the internal pressure of the system will only be the pressure of the lift height at the lift height (e) (e) (standard 1 m) in a state in which the internal pressure of the system is independent of the pressure of the water supply water.

It should be noted that although water rising from the branch pipe P _{6 '} enters the auxiliary pressure tank 2' due to the pressure of the tap water when the water is introduced into the system, most of the water flowing into the auxiliary pressure tank 2 ' , is forced out at the stage when the check valve 6A is closed so that the internal pressure of the system is the pressure created by the lift height (e).

Accordingly, water filling and air removal can be simultaneously and normally carried out in such a way that the water poured into the system can be poured at a pressure of the lifting height (standard 0.01 MPa), and the air zone Za for absorbing the pressure of a given surface wL _{1 of} the water level can be provided inside the pressure separating tank 2 of the air separation chamber, as shown in FIG. 6, while there is an air region Za for absorbing the pressure of a predetermined water level surface wL, as shown in FIG. 3 (B).

According to the present invention, for example, as shown in FIG. 4, FIG. 5, a long square cylinder 1K comprising a long left sheet 1L connected to a long right sheet 1R, in cross section similar to the letter L, upper cover 1U and lower cover 1D, respectively, removably attached to both ends of the square cylinder 1K, the left sheet 1L, similar to the letter L in cross section, has a plurality of cable insertion holes H1 arranged vertically at equal intervals on one side of the LS1, and a plurality of ventilation openings H3 holes on the other side of LS2 located in the positions corresponding to the H1 cable entry holes.

In this case, the left sheet 1L serves to fasten the support element, such as functional modules, etc., to its inner surface, and the right sheet 1R functions as a cover for the square cylinder 1K.

In addition, there is a hole H1 for cable insertion to enable wire connection between the electrical junction box 9A embedded in the wall surface WL or floor surface FL and the temperature control unit to be placed in a monoblock heating device (heater box) in a suitable position ), the hole H1 for inserting the cable is sized to allow a human hand to be inserted into it, and the holes H1 for inserting the cable are typically an extension vatye opening 60 mm wide and 40 mm high, arranged at five locations at equal intervals of 100 mm.

H3 air vents are provided to allow heat to dissipate outward in the monoblock heating device 1, thereby forming an air flow path into the monoblock heating device 1, and they typically are elongated holes with a width of 20 mm and a height of 40 mm.

In this case, when the monoblock heating device 1 is used in a vertical position, the control panel 9B can be placed on the top cover 1U, and when the monoblock heating device 1 is used in a horizontal position, the control panel 9B can be placed on the right sheet 1R, performing the function of a square cover cylinder 1K.

Accordingly, the square cylinder 1K can be disassembled on the left sheet 1L, in cross section similar to the letter L, and the right sheet 1R, by removing the upper cover 1U and the lower cover 1D, and the functional modules that are placed in the monoblock heating device can only be fixed on the left sheet 1L, so that maintenance of the monoblock heating device can be easily accomplished by removing the right sheet 1R serving as the cover of the square cylinder 1K.

In addition, when placing the monoblock heating device 1 in the respective rooms, since the cable insertion holes H1 are arranged in series at different levels, positions for connecting to the electrical junction box 9A located outside can be selected so that the monoblock heating device 1 can be placed in appropriate rooms without compromising appearance.

Additionally, since the air in the room outside the monoblock heating device 1 can flow through the monoblock heating device 1 both through the holes H1 for inserting cables and through the ventilation holes H3, the heat dissipated after heating in the monoblock heating device 1 can participate in the heating of the room , thereby providing the possibility of obtaining a circulating water heating system with heat losses practically equal to zero.

In addition, in the monoblock heating device 1, both edges of the left sheet 1L, in a cross section similar to the letter L, are bent and extended to form the angular side 1A, respectively, as shown in FIG. 4, and the fixing part 1C is molded at the end of the angular side 1A, in cross section similar to the letter L, while the fastener 1F for the butt joint, which will abut against the fastening part 1C of the left sheet 1L, is placed on both edges of the right sheet 1R, in a cross section similar to the letter L, and threaded holes H2 are preferably located on the upper end and lower end of the left sheet 1L and the right sheet 1R, in a cross section similar to the letter L, respectively, are the threaded holes H2 made in the upper cover 1U and the lower cover 1D, respectively, preferably fastened with screws with threaded holes H2 of the left sheet 1L and right-hand sheet 1R, respectively.

In this case, the left sheet 1L and the right sheet 1R each are typically 1.2 mm thick steel sheet, and for mounting if appropriate functional modules are required, such as check valves, T-joints, pressurized air separation tank, etc. e., to the inner surface of the left sheet 1L using a conventional support element, reinforcing ribs 1G in the form of external protrusions are preferably located on the respective lateral sides Ls1, Ls2 and the angular sides 1A of the left sheet, as shown in Fig. 4 (A).

Therefore, the monoblock heating device 1 can be easily assembled and disassembled by inserting the upper cover 1U and the lower cover 1D into the left sheet 1L and the right sheet 1R, respectively, and then fastened with screws, and since the functional modules are placed in the monoblock heating device 1, etc. attached only to the left sheet 1L, maintenance during inspection, repair, relocation, etc. can be easily implemented. In addition, the manufacturability of the fastening operation of the right sheet 1R, which is removed during maintenance, again to the left sheet 1L is not only improved due to the presence of the fastener 1F for the butt joint, as well as the fastening part 1C, but also the fastening part 1C and the fastening element 1F for butt joints perform the function of reinforcing ribs of a monoblock heating device 1.

In addition, as shown in FIG. 6, the pressurized air separation tank 2 and the auxiliary tank 2 ′, located in the monoblock heating device 1, are identical in design and made in the form of a box containing the lower side 2D, front side 2F, rear side 2B, the upper side 2T and the sides 2L, 2R, with the upper side 2T passing to the front side 2F through the front inclined side Sf, the upper side passing to the rear side 2B through the rear inclined side Sb, the connecting pipe J1 is made in the center the middle side 2F, in its vertical direction, the connecting pipe J2 is made in the center of the rear side 2B, in its vertical direction, the connecting pipe J3 is made in the rear region of the upper side T, with two sheets of blades, namely the front blade 2A and the rear blade 2A ', going upward with an inclination towards the rear side, are placed inside the tank 2 between the left side 2L of the tank 2 and the right side 2R of the tank 2 so that the front blade 2A is located in the lower position corresponding to the rear side Tel'nykh J1 pipe on the front side of 2F, and the rear blade 2A 'located in the upper position corresponding to the hose nipple J3 on the upper side of 2T.

In this case, the required volume of the pressure separation tank 2 under pressure can be selected based on the amount of water enclosed in the circulating heating system during room temperature (standard 15 ° C), the amount of hot water (standard 80 ° C) enclosed in circulating heating system during expansion, and air pressure in the tank 2, supplementing the amount of hot water during expansion, given that the corresponding positions of the connecting pipes J1, J2 are preferably below the surface of the water level even at room temperature, when the monoblock heating device is used in the transverse position, and the connecting pipes J3, J2 will preferably be below the surface of the water level when the monoblock heating device 1 is used in the longitudinal position.

In addition, both vanes, vanes 2A in the lower position and vanes 2A 'in the upper position tend to create controlled turbulent flows that are used to facilitate air separation, and if the vanes are each located at an angle of 30 °, they will perform the function of suppressing spontaneous eddy flows regardless of whether the tank is used in a longitudinal or transverse position, so as to obtain divided flows, thereby creating controlled turbulent flows used to facilitate air separation Ha.

The pressurized air separation tank 2 is a small tank made of plastic, assuming that there is no need for a vent valve and a safety outlet valve, and is typically a 0.6 mm thick plastic molded product having a strength (safety margin) ) is approximately three times greater than the strength providing resistance to rupture at high pressure in the circulation system. For a 1 kW radiator, a pressurized air separation tank 2, when used in a longitudinal position, will have a water volume of 0.19 liters at room temperature and a water volume of 0.26 liters at an internal system pressure of 0.01 MPa and at a temperature of 80 ° C, after which the internal pressure of the system becomes 0.04 MPa, and when used in the transverse position, the tank will have a water volume of 0.28 liters at room temperature, and a water volume of 0.34 liters at an internal pressure of the system of 0.01 MPa, and at a temperature of 80 ° C, after which the internal pressure of the system will be 0.04 MPa.

At the same time, if the pressure separation tank 2 of the air compartment is made of translucent plastic, this will make it possible to observe its internal space from the outside, so that it will be possible to visually monitor the state of water entering the tank when the circulating heating system is filled with water, which is convenient when preparatory work and maintenance of the circulating heating system.

Accordingly, in the case of a pressurized air separation tank 2 according to the present invention, regardless of whether it is used in a longitudinal or transverse position, the hot water stream entering the tank 2 is converted into controlled turbulent flows that facilitate air separation using two sheet blades 2A and 2A ', and this process, together with a rapid decrease in the flow rate of hot water entering the tank, will cause the air foam in the water to suitably rise up to separate it, so that spirit caught in the circulation system, is securely held within the pressure tank 2 is air separation. For this purpose, a pressurized air separation tank is arranged in a circulation system without the need for a safety relief valve and a ventilation valve required in the case of example 1 of a conventional system (FIG. 7), so that the entire circulation system relating to example 1 of a conventional system (Fig. 7), excluding the radiator, can be placed in one block of the monoblock heating device 1, thereby allowing universal use of the monoblock heating device 1 as in the longitudinal and in transverse positions and achieve a reduction in its size.

In addition, since the pressurized air separation tank 2 can be manufactured with small dimensions and low cost, it can be used as an auxiliary tank 2 ', with the size of the monoblock heating device 1 being reduced.

In addition, as shown in FIG. 2, when the monoblock square cylinder-shaped heating device 1 of the present invention is used in a longitudinal position, the pressurized air separation tank 2 is preferably positioned such that its front side 2F is on the upper side and its rear side 2B is located on the lower side of the monoblock heating device 1, the connecting pipe J3 of the upper side 2T is connected to the tubular heater 4 through a pipe system gadgets, and the pipe S of the outlet side is connected to the connecting pipe J2 of the rear side 2B through a piping system, while the connecting pipe J1 of the front side 2F is closed by a cap 2C.

In this case, the connection between the connecting pipe J3 and the tubular heater 4 and the connection between the connecting pipe J2 and the pipe S of the outlet side is preferably carried out using an ethylene-propylene rubber pipe.

Accordingly, in the pressurized air separation tank 2, as shown in FIG. 6 (D), the circulating water will have a water level surface wL ₁ at room temperature and a surface wL ₂ at 80 ° C, the inflowing water Fin coming from the connecting pipe J3 changes to the effluent water Fout exiting the connection pipe J2, and inside the tank 2 there will be a sharp decrease in the flow rate of the inflowing water Fin, which will be divided into the upper stream F1 and the lower stream F2, guided by the blade 2A 'in the lower position inside the tank 2, the upper flow F3 and the lower flow F4, guided by the blade 2A in the upper position inside the tank 2, after which the air foam in the water is separated to rise up in the direction of the air region Za, which is in the upper part of the tank 2, closed by the lid 2C, and hot air-free water can circulate in the radiator 8.

Accordingly, if the pressurized air separation tank 2 according to the present invention is used in the longitudinal position, as shown in FIG. 6 (D), it performs the corresponding functions of the closed expansion tank and the air separation device provided in Example 1 of the conventional system (FIG. 7 ), so that it becomes possible to reduce the size of the monoblock heating device 1.

In addition, when the square cylinder monoblock heating device 1 is used in the transverse position, the pressurized air separation tank 2 is preferably arranged such that its upper side 2T is located on the upper side and its lower side 2D is located on the lower side of the monoblock heating device 1, wherein the connecting pipe J1 of the front side 2F is connected to the tubular heater 4, the connecting pipe J2 of the rear side 2B is connected to the pipe S side yield us, while the connecting pipe J3 upper side is closed 2T 2C.

In this case, the connection between the connecting pipe J1 and the tubular heater 4 and the connection between the pipe S of the outlet side and the connecting pipe J2 is preferably carried out using a pipe of ethylene-propylene rubber.

Since the connecting pipe J3 of the upper side 2T is airtight closed by the cap 2C, the area inside the tank 2 under the connecting pipe J3 is the air area Za.

Accordingly, in the pressurized air separation tank 2, as shown in FIG. 6 (C), the circulating water will have a water level surface wL ₁ at normal temperature (15 ° C) and a surface wL ₂ at 80 ° C, so that flowing Fin water circulating from the tubular heater 4 flows into the tank through the connecting pipe J1, the flow of inflowing water, the flow rate of which drops, is divided into the upper flow F1 and the lower flow F2 by the front blade 2A, after which the air foam in the inflowing water is separated, to rise up and flow in the supply water is also separated into the upper stream F3 and the lower stream F4 by means of the rear vanes 2A 'to become the effluent water Fout, which is supplied to the outlet side pipe S through the connecting pipe J2 of the rear side 2B, thereby forcing air foam incorporated into the inflowing water , separate to rise up into the airspace Za, available at the top of tank 2.

Since the connecting pipe J3 of the upper side 2T is closed by a cover 2C, and the maximum pressure of the circulating water after heating and expansion in the air region Za in the upper part of the tank 2 is not higher than the critical value for the burst (standardly one third of the burst pressure), even if the pressurized air separation tank 2 is used in the transverse position, as shown in FIG. 6 (D), the pressurized air separation tank 2 will perform the corresponding functions of the closed expansion tank and stroystva air separation present in conventional system of Example 1 (7), so that it becomes possible to reduce the size of the monobloc heating apparatus 1.

In addition, according to the present invention, for example, as shown in FIG. 2, when the square cylinder monoblock heating device 1 is used in a longitudinal position, the auxiliary tank 2 ′ is arranged such that its front side 2F is located on the lower side and its rear side 2B is located on the upper side, the connecting pipe J3 of the upper side 2T and the connecting pipe J2 of the rear side 2B are closed by a cover 2C, while the connecting pipe J1 of the front side 2F preferably connected to the upper end of the outlet pipe P _{6 ′} extending from the cross T-shaped connection 7A for use in filling with water and venting through the check valve 6C.

In this case, the outlet pipe P _{6 ′} connected to the check valve 6C can move away from any position if it is located in the piping system P ₆ between the pressurized air separation tank 2 and the check valve 6C, while the auxiliary tank 2 ′ can unload water flowing into it and located above the water level surface wL, when water is supplied to the system having said auxiliary tank 2 'located above the outlet pipe P _6' . As shown in FIG. 3, the auxiliary tank 2 ′ typically extends horizontally from the T-shaped cross connection 7A in the flow path of the piping systems P ₆ , P ₇ coming from the pressurized air separation tank 2 to the radiator 8 through a check valve 6C, so that the auxiliary tank 2 'is located on the bent upper end of the branch pipe P _6' .

Moreover, the air inside the system is removed when the water is discharged, due to the force created by the water during filling with water, and this requires a flow velocity of at least 1.2 m / s. If the air has been completely removed, the flow rate should be increased, and at this time the water above the surface wL ₁ , wL of the water level flows into the pressurized air separation tank 2 and the auxiliary tank 2 '. In the case when water flows into the system using tap water, the pressure of the flowing water becomes 0.5 MPa and changes to a value of 0.4 MPa due to the resistance of the piping system, while the flow velocity changes to a value of 9.1 m / s ( water consumption is 15.1 l / min when the water tap is fully open).

Then, there is the internal pressure of the system, created by the movement of water molecules, which is applied evenly to the functional modules, the piping system in which water is present, in addition to the spontaneous expansion pressure of the water, which is regulated inside the pressure separation tank 2, created by the increase in temperature water, air compression caused by spontaneous expansion pressure, and in a system with a thermal power of 3 kW there is a large amount of water (14 liters), and in the case of At a water temperature of 80 ° C, a pressure of 0.16 MPa is created, which cannot be absorbed by one pressure separating tank 2, but the internal pressure of the system decreases to 0.04 MPa (the internal pressure of the system is structurally laid in its volume and configuration by setting the initial pressure of 0.01 MPa and a pressure of 0.04 MPa at a temperature of 80 ° C).

Accordingly, the auxiliary tank 2 'can be placed in any area where there is water, and since the auxiliary tank 2' is located above the check valve 6C, from which water is discharged, it can discharge water above the water level surface wL.

It should be borne in mind that if water inside the auxiliary tank 2 'is not unloaded, the air region Za described above cannot be fixed and the internal pressure of the system cannot be absorbed, so that the weakest sections of the functional modules and piping system will be destroyed.

When the square cylinder monoblock heating device 1 is used in the transverse position, the auxiliary tank 2 'is positioned so that its lower side 2D is located on the upper side, and the connecting pipe J1 of the front side 2F and the connecting pipe J2 of the rear side 2B are closed by a lid 2C. while the connecting pipe J3 on the lower side is preferably connected to the upper end of the branch pipe P _{6 '} extending from the T-shaped connection 7A, for use when filling with water and venting through check valve 6C.

Accordingly, a one-piece heating device 1, in which an auxiliary tank 2 'is connected to a check valve 6C, can not only provide a hot water circulation system that is completely free from any risk of tearing inside the system, but also can cope with an increase in the amount of water filling the system, for example, a change in thermal power from 1 kW to 3 kW, without any changes in the monoblock heating device 1, and also performs filling the system with water and removing air from the system.

In the heating system according to the present invention, one block of the monoblock heating device 1 is arranged in such a way as to ensure the operation of one block of the radiator 8, so that even if one block of the monoblock heating device 1 fails, the other monoblock heating devices 1 and the corresponding radiators 8 will working condition, and therefore it is possible to avoid the case of a malfunction of the heating system in all rooms of the building, thereby preventing a situation in which heating is any part of the building will stop completely.

In addition, since the monoblock heating device 1, including the heating device (tubular heaters), can be located in a place near the radiator 8, there is no heat loss in the circulation of hot water from the heating device to the radiator, and even if heat is generated inside monoblock heating device 1, it will perform the function of heating the room, so here it provides a heating system for the interior, in which there is no heat loss, in fact it will be itelnoe heat.

In addition, since the radiator 8 is a radiator with hot water circulation, heating by means of heat generation can be carried out without the occurrence of temperature spots, and the corresponding radiators themselves can generate heat by heating by separate and independent work performed in the respective monoblock heating devices 1, so that it is possible to freely regulate the heating process as required.

In addition, when upgrading an existing heating circulation system during a building repair, an existing heating circulation system can be easily upgraded to a heating system according to the present invention simply by placing a monolithic heating device 1 according to the invention next to an existing radiator with hot water circulation, ensuring its operation when this leaving the old piping system located under the floor, in the wall, etc., unchanged.

In addition, since a new pressurized air separation tank 2 was developed and used here, capable of performing the corresponding functions of an expansion tank, an air separation device, a safety exhaust valve, and a shut-off valve available in a conventional water heating circulation system (Fig. 7) , the monoblock heating device 1 can be miniaturized and reduced in weight. In addition, the monoblock heating device 1 can operate with a conventional metal radiator and even with a plastic radiator, light in weight, without the risk of corrosion and fire, as a radiator 8, provided that they are radiators with hot water circulation, so that the monoblock the heating device 1 can be used not only in the heating system of a new building, but also in the repair of the heating system of an existing building.

In the heating system according to the present invention, the processes of filling with water and removing air, respectively, are carried out more easily compared to example 1 of a conventional system (Fig. 7), the removal of air from the system can be carried out simultaneously with filling the system with water, and even if water flows into the running under pressure, the tank 2 air separation and auxiliary tank 2 'during filling with water in such an amount that it exceeds the surface of the water level at the beginning of the process, excess water will be discharged in parallel with leniem air so that the air removing device in the radiator is not required, and the internal pressure of the system is absorbed by the Pressure air separation tank 2 and the auxiliary tank 2 ', thereby making it possible to specifically maintenance worker trained not even maintain the system with ease.

In addition, to enable the indicated one lateral side Ls1, having openings H1 for cable insertion, to act as a support and a housing, the reinforcing rib 1G in the form of a small (standardly 6 mm) semicircular protrusion in the cross section is formed so that it goes in the vertical direction in two places on the indicated one lateral side of Ls1, each of these places being in a suitable position (typically at a distance of L11 (40 mm) from the corresponding angles of the indicated one lateral side of Ls1).

The right-hand sheet 1R is attached to the left-hand sheet 1L to combine with it, thereby forming a body, and the right-hand sheet 1R serves as a cover that will be removed during maintenance of various functional modules placed on the inner surface of the left-hand sheet 1L, and, as shown in FIG. 4 (B), a chamfered side 1R ′ having a width L10 (standard 86 mm) is formed on a bent corner portion between one side Rs1 and the other side Rs2 of the right sheet 1R, in cross section similar to the letter L, thereby waving a smooth surface, and the end of said one side of Rs1 and the end of said other side of Rs2 are each bent inward, as shown in FIG. 4 (B), FIG. 5 (D), forming a fastener 1F for a butt joint protruding on a small distance d12 (standard 7 mm). A screw hole H2 is drilled at the upper and lower ends of said one side of Rs1 and the upper and lower ends of said other side of Rs2, respectively.

The top cover 1U is a component located opposite the bottom cover 1D and identical in shape to it that will be mounted and secured to the upper end of the square cylinder 1K of the housing 1 formed by the left sheet 1L and the right sheet 1R, and as shown in FIG. 4 ( C), the top plate 1T is a molded pentagonal sheet with a depth of W1 160 mm and a width of L1 180 mm, in which one side of the rectangle, opposite the right sheet 1R, has a beveled side TS with a length of L10 (standard 86 mm) in position at a distance of W10 (standard 85 mm) from the plot and EP 1T bend the upper plate, wherein the beveled side TS is located opposite the tapered side 1R 'right sheet 1R. The corresponding sides of the upper plate 1T are made in one piece with the vertical part 1P, bent at a right angle down from the upper plate 1T, the vertical part having a height h10 (20 mm).

[Working under pressure tank 2 air separation (6)]

6 (A) is a perspective view of a pressure separating air tank as a whole, FIG. 6 (B) is a front view when viewed in the direction of arrow B in FIG. 6 (A), FIG. 6 (C) - a view in longitudinal section along the line of the OS in Fig.6 (A), Fig.6 (D) is a schematic representation of a pressurized air separation tank used in a longitudinal position.

The pressurized air separation tank 2 is a newly designed tank located in the hot water circulation path of the monoblock heating device 1, which eliminates the need for an expansion tank, an air separation device, a drain shutter valve and a safety drain valve required in case 1 of a conventional system (Fig.7).

The pressurized air separation tank 2 is a molded article made of translucent plastic, having a wall thickness of 0.6 mm as a whole, including a lower part in the form of a box with a length (L2) of 140 mm, a height (h3) of 55 mm and a width of (w2 ) 50 mm and the upper part in the form of a pyramid with a trimmed top having the upper side 2T width (w3) 38 mm, length (L3) 70 mm and height (h4) 30 mm, and the front side 2F of the box and its rear side 2B, opposite the latter, which have connecting pipes J1, J2 with an outer diameter of 13 mm and a thickness of 0.5 mm ki located in a position at a distance of (d5) 30 mm above their lower end, and a connecting pipe J3, identical in size to J1, J2, is located on the upper side of 2T, in a position corresponding to the center of its width w3 and at a distance (L5) 55 mm from the rear side of 2B.

In addition, to secure the rubber pipe 5A or rubber cover 2C for use in piping systems P ₁ -P ₇ to the connecting pipes J1, J2, J3, respectively, the protrusion 2G 1 mm wide, protruding by 0.5 mm, is performed in two places located at a distance of 6 mm from each other on the periphery of each of the connecting pipes J1, J2, J3.

In addition, as shown in FIG. 6 (C), the front blade 2A and the rear blade 2A ′ are located between the side 2L of the tank 2, on the left, and the side 2R of the tank 2, on the right, inside the tank 2, so as to overlap the inner space of the tank 2.

The front blade 2A with a width of W5 35 mm and a thickness of 6 mm is positioned so that it goes upward with a slope of 30 ° towards the rear side, and its front end is located at a distance (L6) 25 mm from the front side 2F and a height (h5) of 20 mm from the bottom of the 2D tank, while the rear blade 2A 'with a width of W6 30 mm and a thickness of 6 mm is positioned so that it goes upward with a slope of 30 ° towards the rear side, and its front end is located at a distance of (L5) 55 mm from the rear side 2B and at a height (h6) of 35 mm from the lower side of 2D, thereby setting the inside s tank 2 volume at 0.5 liters.

Accordingly, when the pressurized air separation tank 2 is used in the transverse position, as shown in FIG. 6 (C), and the surface of the water level at room temperature (15 ° C) is kept at wL ₁ , the water volume is 0.28 liters and the air volume (free space) is 0.22 liters, the inflowing water Fin enters from the connecting pipe J1 of the front side 2F at a flow velocity of 0.885 m / s and is converted into a slow flow F2 with a flow velocity of 0.118 under the front blade 2A, while flow F1 over the front 2A spatula converted to a stream with a flow rate lower than the flow F2, thereby separating water from the air, whereupon the separated air will rise into the air area Za in the upper part of the tank 2.

In addition, the part of the air that was not separated by the front blade 2A, due to the fact that the flow F4 under the rear blade 2A 'has a low flow velocity of 0.06 m / s, and the circulating water is divided into slow flows F1, F2, F3, F4 with the front blade 2A and the rear blade 2A ', respectively, so that it mixes, the air remaining in the circulating water is completely separated.

In addition, the water level surface of the circulating water, which expands at high temperature (80 ° C), reaches the level wL ₂ , and the process occurs when the connecting pipe J3 of the upper side 2T is closed with a rubber cap 2C, so that the air region Za will contain compressed air with permissible pressure.

Furthermore, when the tank 2 is used in a longitudinal position, it is positioned such that the front side 2F is located on its upper side, as shown in FIG. 6 (D), the inflowing water Fin enters the tank through the connecting pipe J3 of the upper side 2T and passes into the effluent water Fout, discharged through the connecting pipe J2 of the rear side 2B, the surface of the water level is wL ₁ at room temperature, so that at the beginning of operation, tank 2 with an internal volume of 0.5 liter has a water volume of 0.19 liters and free volume space va (air volume) of 0.31 liter, and the surface of the water level reaches wL ₂ when heating temperature for heating to reach 80 ° C.

Further, the flow velocity of the inflowing water Fin of 0.885 m / s decreases sharply inside the tank 2 when the flow collides with the rear blade 2A ', after which the flow F1, directed upward by the rear blade 2A', is converted into the front stream F3 and the back stream F4 the front blade 2A, the front stream F3 and the rear stream F4, together with the lower stream F2, are converted into separate streams with corresponding low flow rates so that they mix, thereby separating air from water, after which the separated air becomes compressed air (standardly not more than 0.04 MPa) in the airspace Za.

[Tubular heater 4 (figure 2)]

As the tubular heater 4, an energy-efficient SC heater (product name) is preferably used, having a high specific power of 30 W / cm ² and a thermal efficiency of 95%, manufactured by Netsusho Kabushiki Kaisha by spray-molding an insulating layer, an electrically conductive layer and a heat insulating layer on the pipe from of stainless steel.

The tubular heater 4 has the form of a pipe with an outer diameter of 15.88 mm, a length of 280 mm and a wall thickness of 2 mm, with one pipe having a power of 1 kW, and the outer periphery of both ends of the pipe are sandblasted to form rough surfaces. If thermal power of 3 kW is needed, three tubular heaters 4 can be used.

In addition, if the periphery of the pipe is covered with heat insulating material, this leads to an increase in the efficiency of heat generation.

[Pipes 5A for use in a piping system (FIG. 2)]

Pipes 5A for use in a piping system are used to form water transfer paths within a monoblock heating device 1 and for pipes used in piping systems P ₁ -P ₇ , and are a conventional rubber pipe made of ethylene-propylene rubber, wall thickness 3 mm and inner diameter 14 mm, and a conventional rubber pipe has excellent characteristics in terms of service life, heat resistance, resistance to low temperatures and resistance to solvents, while being light in weight and flexible.

[Check valves 6A, 6B, 6C (figure 2)]

Non-return valves 6A, 6B, 6C, each of which is a shut-off valve of the corresponding water transmission path, are located in the monoblock heating device 1, and a non-return valve manufactured by Barophic Cop is used as a non-return valve.

Installation of functional modules, etc. in a monoblock heating device 1 is carried out in the assembly shop, and, for example, in the case of a monoblock heating device 1 placed in a longitudinal position, as shown in figure 2, the bottom cover 1D is rigidly attached to the left sheet 1L, while the lower end of the left sheet 1L vertically adjoins the vertical part 1P of the bottom cover 1D so as to be flush with it, and the fastener 1V for butt jointing is attached to the lower end of the left sheet 1L with screws through screw holes H2, then the base 11 is placed and mounted on the lower plate 1B made of flat sheet steel with a thickness of 3 mm and a width of 50 mm, the lower cover 1D, and the legs 3S of the circulation pump 3 are attached to the base 11 with bolts so as to install the circulation pump 3.

Then, a conventional hat-shaped steel element (not shown) obtained by folding a 1.6 mm thick steel sheet can be attached to the inner surface of the left sheet 1L having reinforcing ribs 1G of arbitrary length and height, then an air separation tank 2 operating under pressure, auxiliary the tank 2 'and tubular heaters 4 arranged in three rows are mounted and mounted on a steel support element (not shown) extending from a conventional hat-shaped steel element, after which the rotary connector 3F is circulated of the pump and tubular heaters 4 are connected to each other using a piping system using rubber pipes 5A and hose clamps 5B, and tubular heaters are also connected to each other using a piping system so that a water inflow path is formed in the monoblock heating device 1, starting from the return side pipe R, then the circulation pump 3, then the tubular heaters 4, then the pressurized air separation tank 2, then the outlet side pipe S, as shown in FIG. 2 (A).

In this case, the pressurized tank 2 of the air separation (main tank) and the auxiliary tank 2 'are identical in design, and, as shown in FIG. 2 (C) and FIG. 2 (D), they are mounted in a longitudinal position in which the upper side 2T becomes a side surface, the connecting pipe J3 of the upper side 2T located on the side surface of the main tank 2 is connected to the tubular heater 4, while the connecting pipe J2 of the rear side 2B is connected to the radiator 8, and the connecting pipe J1 of the front side is closed by a cap oh 2C.

In this case, as shown in FIG. 3, the T-connection 7A having a check valve 6C is connected to the pipe (piping system) P ₆ in the lower position of the pressurized air separation tank 2, while the check valve 6B is located in the lower the position of the T-shaped connection 7A, and the T-shaped connection having a check valve 6A, is located in the lower position of the check valve 6B, thereby forming a piping system P ₇ .

In addition, the outlet pipe P _{6 ′} extends horizontally from the T-joint 7A, and the connecting pipe J1 located on the lower surface of the auxiliary tank 2 ′ is connected to the bent upper end of the outlet pipe P _{6 ′} .

More specifically, in the auxiliary tank 2 ′, the front side connection sleeve J1 on the lower side 2F is connected to the check valve 6C through the exhaust pipe P _{6 ′} , and the rear side connection pipe J2 on the upper side and the connecting pipe J3 of the upper side 2T on the side are closed lid 2C, while the piping system of the circulating system from the pressurized air separation tank 2 to the radiator 8 is connected to the piping system P ₆ , P ₇ using an outlet pipe P _{6 '} , thereby absorbing internally e the pressure of the system, which increases due to the movement of water molecules when the temperature of the water increases.

Further, the tubular heater 4, the circulation pump 3, the thermostat (not shown) and the temperature sensor (not shown) are connected to each other by electrical wiring, using the gaps provided between the functional modules, and they are connected to a printed circuit board (not shown) and a control panel 9B mounted on the top cover 1U.

[Mounting monoblock heating device 1 (figure 1, figure 2, figure 3)]

The radiator 8 is attached to the wall surface WS using a mounting bracket, and the right sheet 1R of the monoblock heating device 1 in the longitudinal position is removed by removing the screws, while the outlet side pipe S (supply pipe) and the return side pipe R are connected to the inlet 8S for supplying hot water and an outlet 8R for draining hot water, located under the radiator 8, and electric wires for a power source in a monoblock heating device 1 and a wire output from an electrical distribution box 9A ki embedded in the wall surface WS, are connected to each other through an arbitrary aperture of the holes H1 for inserting cables executed by reaming left sheet 1L in five places.

The monoblock heating device 1 is attached to the wall surface WS, with the left sheet 1L having reinforcing ribs 1G located on the side of the wall surface WS.

[Filling with water, air removal (figure 3)]

As shown in FIGS. 3 (A), 3 (D), when the check valve 6B is closed and the valves 6A, 6C are open, the tap (a) of the tap water is connected to the check valve 6A by means of a pressure hose (c), then short the transparent hose (d) is attached to the check valve 6C, then the lifting height (e) is maintained, while the transparent hose (d) rises 1 m, after which the end of the transparent hose (d) is inserted into the bucket (b).

Further, the tap water tap opens and tap water flows through the check valve 6A at the pressure of tap water, which is denoted as water flow w, and when water flows into the bucket (b) through the check valve 6C, and the check valve 6A and tap (a) tap the water is closed so that the water pressure in the system returns to the set pressure specified by the elevation (e) of the lift of the outlet side, after which the check valve 6C closes and the check valve 6B opens.

At the same time, air is in functional modules, etc. in the path of the water flow inside the radiator 8 and the monoblock heating device 1 is removed during the influx of water due to the pressure of tap water, so that the required amount of water can be introduced into the water heating circulation system with a predetermined pressure (0.01 MPa) set by the height (e ) lifting.

After that, power is supplied to start the water circulation, and if extraneous noise is not created by the circulation pump 3 and the tubular heater 4, we can conclude that the air from the system is removed correctly.

More specifically, as shown in FIG. 3 (D), an initial pressure of 0.01 MPa in the system is introduced by filling the system with water and removing air from the system so that the check valve 6B closes so that the water flow w is limited to one direction from the bottom side, after which the check valve 6A and the check valve 6C open, as a result, the check valve 6A serves as an inlet for water, and the check valve 6C serves as an outlet for draining, then the check valve 6A and the tap (a) of tap water are connected to each other with others using a pressure hose (c), then a check valve 6C and a bucket (b) into which a small amount of water is introduced, are connected to each other through a transparent hose (d), while maintaining the lifting height (e), and a transparent hose ( d) on the side of the bucket (b) is maintained at a height of 1 m above the check valve 6C.

In this case, if a transparent hose (d) is used, the air foam will be visible to the naked eye, and if water is introduced into the bucket (b) and the end of the transparent hose (d) is guaranteed to be inserted into the water, it is possible to see with the naked eye the air foam floating on water surface.

Then, if the transparent hose (d) is maintained at a lift height (e) of 1 m above the check valve 6C, the internal pressure of the system changes to zero by stopping the water supply, and the internal pressure of the system changes to 0.01 MPa due to the height pressure lifting the transparent hose (d) so that the initial pressure set by the lifting height (e) can be introduced into the flooded water inside the system.

More specifically, if the tap water tap (a) is open, the water flow w flows into the system and the water flows into the pressurized air separation tank 2 and the auxiliary tank 2 ′ above the predetermined initial water level surfaces wL ₁ , wL due to the force provided the flow of water w, together with the pressure of tap water. However, if air removal along with extraneous noise is detected inside the bucket (b), and the tap (a) and the check valve 6A are closed to stop the water supply, the internal pressure of the system stabilizes at a given initial pressure of 0.01 MPa, specified by the height (e) of the lift transparent hose (d), so that in the pressurized tank 2 air separation surface wL ₁ the water level becomes constant and in the auxiliary tank 2 'the surface wL water level becomes constant (from 10 mm to 20 mm above the front side 2F), while finding water above the surface of the water level, it is discharged into a bucket (b) together with air through a non-return valve 6C and a transparent hose (d), so that the system can be filled with an amount of water of 14 liters in the case of a thermal power of 3 kW and an amount of water of 4.4 liters per case of thermal power 1 kW.

Next, the check valve 6C closes and the check valve 6B opens to fix the flow path of the circulating water during operation.

At the same time, although the internal pressure of the system as a whole is adjustable, as shown in Fig. 7 (A), by placing a pressure reducing valve in the water inflow section, in order to fix the set pressure, while measuring the maximum pressure using a pressure gauge installed on the boiler, in which the pressure is high and the high pressure is vented through the pressure relief valve. However, there is no valve to reduce the pressure of tap water to the initial pressure (0.01 MPa), since the pressure is too low, and the pressure gauge and safety drain valve are difficult to place in the monoblock heating device 1, so that the tank is applied in the present invention using lifting height pressure while holding the regular transparent hose (d) at high altitude.

At the same time, in a demonstration experiment, it was confirmed that water flows into a pressurized tank 2 of the air separation and auxiliary tank 2 'when filling with water, and the initial pressure is introduced into the pressurized tank 2 of the air separation and auxiliary tank 2' while holding a transparent hose (d) at high altitude, and also the water inside the auxiliary tank 2 ′ is stabilized on the surface wL _{1 of} the water level and the surface wL of the water level, and also the internal pressure of the system changes to 0.04 MPa at a temperature of 80 ° C.

Then, when filling with water, the water flowing into the pressurized water separation tank 2 and the auxiliary tank 2 ′, which are airtight, flows due to the amount of air compression, since in the pressurized water separation tank 2 and the auxiliary tank 2 ′ there is air (in any case, water is located above the water surface of each tank), but the water inside the transparent hose (d) on the side of the bucket (b), maintained at high altitude, when the water supply stops, is discharged into the bucket (b), where itozvraschaetsya to the initial state in which there is air, and the water, located above the water discharged by stabilizing the internal pressure of the system.

In the case when the monoblock heating device 1 is located horizontally below the lower surface of the radiator 8, etc., the monoblock heating device 1 contains functional modules identical to those used in the preferred embodiment of the invention (Fig. 1 and Fig. 2), however, since the monoblock the heating device 1 is placed in the transverse position, the pressurized air separation tank 2 can be located horizontally, that is, it can be located so that its lower side 2 D is located on the lower side of the monoblock heating device 1, and its upper side 2T is located on the upper side of the monoblock heating device 1, and the auxiliary tank 2 'is located so that its lower side 2D is located on the upper side of the monoblock heating device 1, and its upper side 2T is located on the lower side of the monoblock heating device 1, that is, the auxiliary tank 2 'is located in an inverted position relative to working under pressure of the air separation tank 2, and the outlet pipe P _{6 ′} extends upward from the intermediate point between the piping system P ₆ and the piping system P ₇ inside the system through a check valve 6C, the connecting pipe J3 on the lower side of the auxiliary tank 2 'is connected to the upper end of the discharge pipe P _{6 '} , after which the auxiliary tank 2' will be able to discharge the inflowing water and function as a pressure tank 2 ', thereby fixing the air region Za.

In addition, the monoblock heating device 1 is preferably positioned such that the beveled side 1R ′ of the structure similar to a square cylinder, that is, the beveled side of the right sheet 1R, is located on the front surface of the structure, and if the control panel 9B is located on the surface along the beveled side 1R ′ , this will be preferable in terms of appearance and control.

More specifically, the pressurized air separation tank 2 is in the position shown in FIG. 6 (C), heated water flows into the connecting pipe J1 of the front side 2F through the tubular heaters 4 and is discharged through the connecting pipe J2 of the rear side 2B, and the connecting pipe J3 of the upper side 2T is covered by a lid 2C, so that the pressurized air separation tank 2 can function as a pressurized tank 2 'to fix the air area Za as required.

Then, the auxiliary tank 2 'is in the reverse position shown in Fig.6 (D), the connecting pipe J1 of the front side 2F and the connecting pipe J2 of the rear side 2B are closed by a lid 2C, and the connecting pipe J3 of the upper side 2T located on the lower side of the auxiliary of the tank 2 ′ is connected to the upper end of the outlet pipe P _{6 ′} through a check valve 6C, so that most of the upper part of the auxiliary tank 2 ′ will become the air region Za for absorbing the internal pressure of the system.

Accordingly, even if the monoblock heating device 1 in the form of a square cylinder is placed horizontally, controlled turbulent flows are created by separated flows of circulating hot water using the front blade 2A and the rear blade 2A 'in the pressurized air separation tank 2, and the controlled turbulent flows cause a separation process air and the process by which the separated air foam is combined with air in the Za region in the upper part of the tank 2, after which the monoblock heater The device 1 will show the same effect as in the case when it is located longitudinally, so that the original objective of the invention is achieved, and the auxiliary tank 2 'together with the pressurized tank 2 of the air separation works as a pressurized tank, thereby absorbing system internal pressure.

In the present invention, in addition to the pressurized air separation tank 2, an auxiliary tank 2 ′ is installed, identical in design to the pressurized air separation tank 2, however, since the auxiliary tank is installed only to add the air region Za to the air region Za to absorb pressure in the pressurized tank 2 of the air separation, in order to improve the absorption efficiency of the internal pressure of the system, the auxiliary tank 2 'may be absent in the case of a heating system with a large volume of water having a capacity of not more than 1 kW.
