THE INVENTION:

The basis for this submission is the utility model granted under GM number 11214 of 04/15/2010, which is hereby to be referred to as the S.C.B Smart Climate Bar through expanded functionality. It is an inexpensive add-on device for conventional heating radiators (indoor heat exchangers) available on the market, which enables both heating and air conditioning functions to be carried out using conventional heating radiators (from one and the same radiator). Energy is saved in the heating function, since the conventional radiators can then be used as low-temperature radiators. With a connection to a cold water set (or similar cold water supplier, ground water, geothermal collectors, flat plate collectors, probes, river water, sea water = passive cooling), the same existing flow / return system for radiator heating can also be used for cooling as air conditioning.

STATE OF THE ART:

So far, these conventional radiators (interior heat exchangers) could only take over heating functions. Most of them can only fulfill this function with a high flow temperature. New generations, so-called low-temperature heating radiators, can also be used at a lower flow temperature, but they cannot provide air conditioning. As is known, radiators - as indoor heat exchangers - are used worldwide only for heating purposes. If you also want to air-condition, an additional indoor heat exchanger must be purchased for cooling purposes, of course with associated new installations - regardless of whether direct evaporation devices (require a lot of refrigerant) or water chillers are used, which is technically and economically a great effort.

DISADVANTAGES OF CONVENTIONAL HIGH TEMPERATURE RADIATORS:

Another disadvantage of conventional high-temperature radiators is that exchange only takes place by convection and radiation. That is why the moisture content is very poor during the heating season. Due to the higher flow temperature, the formation of dust on the radiators and walls is a well-known problem. Both go hand in hand with higher energy requirements (and thus heating and energy costs). In addition, there is an asymmetrical distribution of heat (heat is concentrated on the ceiling and it is noticeably cooler in the floor area).

DISADVANTAGES OF CONVENTIONAL AIR CONDITIONING SYSTEMS: [0004] very loud

[0005] higher (high) acquisition costs

Higher installation costs

[0007] higher operating costs

[0008] unpleasant cold with direct evaporation [0009] one more castle per room

ADVANTAGES OF USING THE CLIMATE VENTILATION BAR:

By using the air-conditioning air bar, the heat transfer coefficient k is increased from 14 W / m2 (conventional radiators without air-conditioning air bar) to approx. 23.25 W / m2 (conventional radiators with air-conditioning air bar). This means heating cost savings of 30 to 40% and for the first time enables the use of low-temperature heat pump heating on the same installation with conventional radiators. This saving means a considerable reduction in the pollutants that arise when burning fossil raw materials, especially CO2 (burning Im3 gas = 1.9 kg CO2 and 11 heating oil = 2.7 kg CO2).

The gentle air circulation that is achieved with the air-conditioning bar results in an almost symmetrical distribution of air humidity and interior temperature. This results in very favorable air conditioning (as no new installation is necessary).

The air conditioning bar can be equipped as standard with a dust and pollen filter and optionally with an odor filter (activated carbon). A UV-C light source can also be installed as standard in order to effectively reduce bacteria and viruses in the interior.

Heating: A conventional flow / return system (thermal bath, boiler, solar, pellet, etc.) can still be used.

Air conditioning: The same flow / return system can be used (e.g. with a water chiller with dew point control)

BENEFITS FOR THE ENVIRONMENT AND PEOPLE:

Only one system for heating and air conditioning purposes

Energy saving

Material savings

CO2 reduction

Emission Reduction

[0020] Prevents dust carbonization

Prevents dust and pollen from spreading pollen, bacteria and viruses in the interior by UV-C.

[0022] Symmetrical temperature and humidity distribution (= pleasant room climate, increased comfort)

STRUCTURE OF THE CLIMATE AIR BAR:

The bar consists of several low-voltage flat-axial fans (protection class low voltage) with removable filters and UV-C light source. Length: variable, depending on the radiator dimension, noise level approx. 23-28 dpa at full speed.

The air conditioning bar Fig. 1 shows (1) mounting options for conventional heating convectors (directly below or directly above conventional heating radiators) in order to apply filtered air circulation to the entire exchange area. Because of this, a higher heat transfer coefficient k is achieved, with dew point control being advantageous for the air conditioning function.

Fig. 2 shows the simple design / structure of the air conditioning strip (1) with dust pollen filter (2) and optionally activated carbon filter (3) and flat axial fans (4) and finger protection grille (5). The power supply and electronic control are provided by the controller (6).

Claims (5)

Expectations 1. The Smart Climate Bar, Smart Climate Bar, is an additional device in the form of a lightweight wise designed housing in which one or more, speed-controlled flat axial fans, a rail-guided, flat air filtration compartment and an additional UV-C light source are located. The device can be integrated above or below or in the existing radiator. This leads to increased air circulation by means of gentle and quiet application. As a result, low-temperature heating in winter and dew point / temperature-controlled air conditioning in summer is guaranteed, and all of this on the same indoor heat exchanger on the existing piping. 2, The device according to claim 1 is characterized in that the existing radiators are subjected to gentle and quiet air circulation in order to achieve a higher heat transfer coefficient and thus to avoid an asymmetrical room temperature and humidity including stratification. 3. The device according to claims 1 and 2 is characterized in that additional built-in filters, fine dust, dust formation and bollard pollution as well as odor nuisance in the room reduce or prevent. 4. The device according to claims 1 and 2 is characterized in that conventional radiator heating systems can be combined with low-temperature heating systems and heat pump systems. 5. The device according to claims 1 to 5 is characterized in that conventional radiator heating can be equipped with an integrated air filtration cassette and UV-C light source in order to effectively reduce bacteria and viruses in the interior.
