DE102004059335A1 - Air cooler/Low temperature-heating body for air circulation motor - Google Patents

Abstract

u The air cooler/low temperature-heating body comprises a number of rigid-walled neighbouring plates (1) that are connected together, via spacer rings, by union connections (11). There is a continuous air-gap (3) of between 3 to 25 millimetres between the plates. The plate section (1.1) has a radial ventilation air wheel (2) with a regulating outer or inner running electric motor (2.1) that is screwed on to the outer plate via rubber insulation (2.2) as well as being screwed to the plate packet rear side of an air-suction ring (4). There is an elevation profile in the plates~ inner hollow chamber which is fixed via point welding, whilst there is an automatic regulation valve for the heating & cooling plant (11.1) built around the connections. The suction ring may have an outer air mixture cylinder (5) with an outer air valve (5.1).

Description

to Time will be next to the casting u. Steel radiators Flat radiators with internal air transfer blades built-in. For the former usual System temperatures of 90/70 ° C u. today's low-temperature heating systems of 70/55 ° C have this with about 1.6 times the transfer surface installed become. However, since in future the environmental, solar u. heat pump u. Condensing technology in passive houses is installed, it is necessary to lower the heating water temperature to 45/35 ° C. Here you have to the radiators about 4.2 times the transfer area compared to the 90/70 ° C system to have. As this is the case with existing systems or even with new buildings Space reasons not possible is currently only floor, wall or ceiling heating systems used. For room cooling are currently used standard radiator not usable, since it is not sufficient from the cooling surface u. the cold air sinks down u. a reasonable total room air cooling not given is.

at the passive houses an airtight outer shell is prescribed the with appropriate building vacuum measurements checked becomes. For these houses Therefore, a controlled ventilation is required. The disadvantage in a total ventilation system is that the individual spaces regardless of their current use be vented, which in the winter months leads to significant operating costs.

In addition, the supply air ducts to the individual accommodation zones or rooms, which are used in new buildings u. especially with old buildings are difficult to assemble.

function Description

In the currently used for use DIN radiators u. Flat radiators, the heat transfer from the heating medium to space heating by temperature difference takes place with natural buoyancy. In the patentable fan cooling u. Low-temperature radiator for circulating or Außenumluftbetrieb is the u. Outside air via radial ( 2 ), Roll ( 9 ) or axial fan ( 14 ) at high speed to the heating u. Cooling plates ( 1 ) over the air gap ( 3 ) with 3 to 25 mm in cross-flow compared to the water flow, so that a high transmission coefficient is achieved.

Due to the high transmission power through the fan operation u. by the small, lateral distance from each other, the heating u. Cooling plates ( 1 ) are installed in the dimensions of DIN radiators or flat radiators 90/70 ° C, which means that the outer dimensions (length and width) do not increase even at 45/35 ° C medium temperature.

In the transitional periods and when no ventilation is needed, the heating and cooling plates ( 1 ) available radiation u. Convection heat without fan operation for room heating. The situation is different with cooling mode. So that the cold air does not sag down, it is necessary to commission the fan in cooling mode.

The claim 1, under 1 + 1.1 includes that the radial fan ( 2 ) with the adjustable external or internal rotor motor ( 2.1 ) in the middle heating u. Cooling plate recess ( 1.1 ) via the air intake ring ( 4 ) sucked in rear or outside air into the air gap ( 3 ) between the heating u. Cooling plates ( 1 ) injected at high speed u. is heated or cooled. For the air control are at the sides air baffles ( 8th ) appropriate. The air baffle on the lower side ( 8.1 ) is designed as a condensate tray.

The individual cooling u. Heating plates ( 1 ) are soldered, welded or screwed spacer rings with flow hole ( 11 ), so over the entire surface of the cooling u. Heating plate ( 1 ) an exact air gap ( 3 ) according to the required air flow u. the plate size is respected.

To ensure the proportion of fresh air in the room, the outside air through the insulated outer air tube ( 6 ) or a concealed air intake ( 6a ) from the outside to the outer-air mixing cylinder ( 5 ) with the built-in outside air valve ( 5.1 u. the outside air dosing disc with the circulating air throttle ( 5.2 u. the opening magnet ( 5.5 ). Before the outside air from the radial fan ( 2 ) recorded u. into the air gap ( 3 ) is already blown through the outside air metering disc with the circulating air throttle ( 5.2 ) mixed with the circulating air. Since the outside air valve ( 5.1 ) only when fan operation u. Release of the medium circuit opens, the risk of freezing is banned.

To reduce noise is the radial fan with the outer u. Internal rotor motors via soft rubber cushion rings with the first heating u. Cooling plate ( 1 ) connected.

At an old building 3 is a separate axial external fan ( 14 ) with the outside air control flap ( 18 u. the insulated outer air tube ( 6 ) install later via a masonry core hole. The outside air is here according to the speed apply axial fan ( 14 ) via the induction nozzle ( 17 ) with the room air in front of the air intake ring ( 4 ) mixed by induction effect u. the heating u. Cooling plates ( 1 ). This is in the summer u. Transition times a separate room ventilation, even without commissioning of the radial fan ( 2 ).

This means that during this period of operation the radial fan ( 2 ) is only required for cooling operation.

4 includes that for the air flow ( 3 ) the heating u. Cooling plates ( 1 ) under the plate pack of the roller fans ( 9 ) is arranged, which a uniform air flow through the air gap ( 3 ) ensured from bottom to top. On the two sides are the baffles ( 8th ) arranged. The outside air is supplied via the intake duct ( 6 ) to Umluft- u. Outdoor air mixing box with flap ( 12 u. Actuator ( 13 ) led to the suction of the roller fan. Under this box is the condensate drip tray ( 8.1 ) assembled.

In the 5 is the air circulation over the bottom of the plates ( 1 ) mounted air duct channel ( 15 u. the sound-isolated, adjustable axial fan ( 14 ) in the air gap ( 3 ). About the u. Outdoor air mixing box with flap ( 12 ) is the recirculation with the over the isolated outside air duct ( 6 ) outside air mixed u. is via the built-in air damper with servomotor ( 13 ) the axial fan ( 14 ). Under the recirculating air outside air mixed air box ( 12 ) is the condensate drip tray ( 8.1 ) appropriate. The connecting piece for mixing u. Recirculating air can be exchanged so that either the outside air can be brought in from behind or from the side.

Under the 6 + 7 is the air nozzle channel ( 15 ) with the axial fan ( 14 ) are arranged under a normal commercial panel radiator. Due to the heated plates pulled apart, the heating power of this panel radiator is only slightly raised. The rest of the execution corresponds to the 5 , Again, the axial fan ( 14 ) only in winter in severe cold or for room cooling u. Ventilation needed.

Because with the fan cooling u. Low-temperature radiator for circulating or Außenumluftbetrieb the room air renewal according to the current use is possible depending on the room, the fan speed u is a temperature control u. the outside air proportion over the u. Outside air damper ( 12 u. the servomotor ( 13 ) or via the separate axial fan ( 14 ) 3 via a room temperature sensor, motion detector u. Timer controlled automatically.

The temperature control is via a in the heating u. Cooling plate ( 1 ) built-in thermally or electrically operated valve.

The Exhaust air escapes via the lower door gap to a centrally located exhaust air system with an overpressure control circuit, so only the exhaust that does not have the temporary operation the toilet u. the kitchen exhaust is sucked off, is returned to the outside.

hereby is achieved that the individual rooms of a building at Installation of the fan cooling u. Low-temperature radiator for Um- or Outside air recirculation mode depending on space usage depending on demand without major technical Effort cooled in the summer, heated in winter u. all year u. vented become.

With this novel heating u. Cooling system can too existing buildings without major structural changes be equipped.
