Description

Air Heating Radiator System

Previous state:-

The Boiler is operated by means of Gas or fuel in order to raise the water temperature which is then pumped into pipes in order to reach the heat exchanger that acts to exchange heat between hot water and cold air inside of rooms. In most cases a radiator is used for this matter. This is the most common way to generate warmth.

There are several shapes, types, and sizes of such heat exchangers made up of Aluminum, cast iron, or others. Sometimes finned coils are used for this matter as well.

The traditional Radiator system has the following disadvantages:

1. Rotate and transmit bacteria and germs inside of rooms, therefore, into the humans.

2. Apply a layer of dirt onto the walls via carbonization due to the high

temperature of water (70-80 deg C.)

3. Heat stagnation in the form of layers at the top of rooms

4. Inability to transmit the heat uniformly inside of rooms

5. Limited ability to influence cold currents floating in from doors and

windows

6. Slow reaction until achievement of desired temperature when started.

7. High surface temperature of the heat exchanger poses a threat to

human when touched especially to children.

8. Loss of large amount of heat into the wall behind the radiator, therefore, fuel and efficiency loss

9. No flexibility in outer shape causing the inability to match changing room designs and decoration taste. Detail description of the invention:- ln order to solve all previous problems, the Air Heating Radiator System (A.H.R.S.) is now being invented which builds on features taken from different sources but modified to fit the new design whereby several new features are also being developed. The existing sources are:

1. Internal part of Split A/C.

2. MPE-Tubes.

3. Traditional Radiators.

The (A.H.R.S.) device is made up of the following parts in general, as per drawings (1), (2), (3):-

1- MPE - Radiator.

2- Fan & fan motor.

3- Control Board.

4- Ambient temperature sensor.

5- Air distributor & Air distributor motor.

6- Control panel.

7- Filter.

8- Inlet water temperature sensor

9- Valve.

10 Frame.

11 Covers. Following is detailed description of the various parts:-

1. MPE - Radiator: - This genuinely developed part combines the shape of conventional radiators and the MPE tubes as per drawing (4). It is made of upper distributor then the MPE tubes then the lower

accumulator. The advantage of the MPE tubes that they provide the largest surface area for heat exchanging.

2. Fan & fan motor: similar to the inner fans of a typical split-type A/C.

They are horizontal and have a certain diameter.

3. Control Board: similar to the control board of the spit-type A/C but with certain modification being that the (A.H.R.S.) has a different operating procedure than the A/C.

4. Ambient Temperature Sensor: a sensor to measure the ambient room temperature. It is connected into the control board, and it is similar to sensors used in the split-type A/Cs.

5. Air distributor and Air distributor motor: similar to existing air

distributor in split-type A/C units whereby it caused the hot air to be distributed evenly into the room. It is controlled by means of a small motor.

6. Control Panel: similar to control panels in the split-type A/C units. The control over the (A.H.R.S.) is effected by means of this control panel.

7. Filter : To help clean the air of Germs and bacteria, and also to prevent small particles from reaching into the unit therefore reduce the

possibility of carbonization, and also reduce the amount of dirt being accumulated on walls and other surfaces.

8. Inlet water temperature sensor: to measure water temperature as it enters the MPE - Radiator. Valve: to allow and also to prevent water from entering the MPE - radiator when opened or closed. It is controlled electrically by the control board.

. Frame: The main frame whereby all above parts are included and especially designed, as per drawings No. (4), (5-A), (5-B). It is designed using material which has small heat transmitting properties, and at the same time it is very strong (special kind of plastic). It is to be provided with clamps to help fix the covers onto the frame.

Covers: this is one of the main features of this system. They cover the external part of this system using clamps to fix it onto the frame. They can be mantled and dismantled and also cleaned easily. They can also be exchanged with various colors and shapes to match room decoration. Made of material which has small heat transmitting properties therefore they are harmless when touched by children and other humans or animals.

Function

When operating the system, the control board gives an order to the boiler and pump and opens the valve so that the boiler begins to heat the water and to circulate it in the pipes until it reached the MPE - Radiator where the inlet water temperature is measured by inlet water temperature sensor, When it reaches the set temperature (say 40 deg. C) the control Board gives a running order to the motors of fan and air distributor. The hot water enters the upper distributor then to the MPE-tubes and then to the lower accumulator of the MPE - radiator, the air enters at room temperature by means of the lower fan in an upward direction among the MPE-tubes where the heat exchange takes place and the warm air is then distributed via the air distributor into the room in a horizontal way. The upper room temperature is set when the A.H.R.S. should stop and the lower room temperature when the A.H.R.S. should run again, this is measured by the Ambient Temperature Sensor. Therefore, when the room temperature reaches the upper room temperature (22.5 degrees for example) the control Board gives an order to stop the Boiler and pump and order the valve to close, and stop the motors of fan and air distributor for a pre-set period of time (about 30 seconds for example) to make use of the temperature of the MPE- Radiator, and when the room temperature reaches the lowest set temperature (20.5 for example) then the control Board gives the order to run again and resume operation as stated above, and so on. Optional Operating Properties:

There are additional operating properties for the device as following:

1- Automatic Operating Characteristic: It is possible with this feature that the device is set to run automatically. The day and time when the devices is needed to start is pre-set so that the device will run and stop according to the set instructions. This feature is most useful in offices and office building, schools, colleges, government offices, etc... so that the device can be pre-set to run Automatically (in an office for example) from Monday to Friday, quarter hour before work starts and to shut down when the work ends, and repeat again every week and so on.

2- Individual Automatic Operation Characteristic: this enables the device to run automatically one time after the date and working hours are pre-set.

3- Sleep Characteristic: usually it is not required to set the temperature during sleep hours to the same degree as day hours. Therefore, this feature enables to set the high and low temperature during night hours to be less than daytime hours and in bigger difference. (For example, the high temperature 19 degrees and the low temperature 15 degrees).

4- Fan speed: the fan can be operated under various speeds, as required.

5- Anti-Freeze characteristic: in the very cold areas, it is common that the water freeze inside of pipes, so this feature prevents the water to freeze. It enables the Boiler and Pump to run and valve to open at set intervals, for example to run 3 minutes every one hour, therefore prevent water from reaching to freeze temperature. This feature can be switched on and off as required. This feature is canceled even it is active during running the device. 6- Economic Operation Characteristic: When the device runs, it receives an order to run the boiler and pump and the valve to open so that the water is heated up and circulated in pipes until it reached the MPE - radiator. The inlet water temperature sensor measures the inlet water temperature, and when it reaches the desired level (say 40 degree) the control board orders the fan and air distributor to run. And when the room temperature reaches the desired pre-set remperature (high temperature) then the control board orders the boiler to stop and continue the pump and device to run so that it make use of the existing hot water inside the pipes. All functions stop after the water temperature is used fully. The device runs automatically again as explained above when the ambient temperature sensor feels that the room temperature has reached the lowest pre-set temperature, and so on.

As explained above, the A.H.R.S. has solved all problems of the conventional radiator. The existence of air filter solved the problems number 1 and 2. The fan, control board, air distributor and ambient temperature sensor solved problems 3, 4, 5, and 6. The especially designed frame and covers solved the problems 7, 8, and 9.

Notes :-

NOTE 1 : The device can be used to cooling the rooms instead of heating by using a chiller instead of Boiler which is cooling the water and pumped by a pump throughout a network of pipes to the heat exchanger. However, when used as a cooler there will be some condensed water, therefore; A special condensed water accumulator is added to the frame, It consist of branch canals, each canal located under each MPE-Tube to collect the condensate water drops which can form on the radiator, they are slightly tilted to the front to pour into the main canal which is also slightly tilted so that the formed water drops are expelled outside the device, as in drawings No. (6-A), (6-B), (6-C).

Note 2: the A.H.R.S. can be operated without its own control panels because it can also be run and controlled by means of other systems which can be introduced by other suppliers.

Note 3: the Intermediate panel has to be added when many of (A.H.R.S) devices are erected somewhere, the (A.H.R.S) devices are connected to the intermediate panel from a side and the boiler and pump are connected from the other side. It is used to connect the electricity to the boiler or pump or both of them when receives at least one running order from any connected (A.H.R.S) device.
