Prior Art

The prior art is an air conditioner that cools air only without making any change in air components. Some types of air conditioners cool and filter air in order to purify it from dust & odors.

Problems of Prior Art

Air conditioners of prior art cool air without making any change in air

components. However, there is a certain type of air conditioners that purify air from dust & odors. Various industrial countries suffer from high rate of air pollution that may cause reduction in oxygen level. Usually oxygen gas concentration in air is 21%; however, this percentage may reduce up to 17% because of air pollution. Air conditioner cools air without raising this reduced level of oxygen in air. Taking into consideration that cooling air in a place with closed windows and doors with no sufficient ventilating, in addition to the presence of large number of individuals, reduces oxygen level in the room, particularly, in crowded places, such as, houses of worship& occasions.

Therefore, air conditioners do not solve this problem but it considers a part of it. Generally, air conditioners cannot solve the problem of oxygen gas reduction. Disclosure of the new invention

The present invention provides a device for generating oxygen gas combined with the other parts of the air conditioner in an electric circuit provided with a sensor. Said sensor measures oxygen level of air, however, it closes the circuit as well as turning oxygen generating device on in case of oxygen level reduction. In contrast to this, said sensor opens the circuit and turns oxygen generating device off if oxygen level increased more than required. Therefore, the air conditioner of the present invention

characterizes by its ability to determine proper oxygen level in the room. This characteristic can be useful in the following casesf

1) Air pollution generally causes reduction in oxygen concentration level. The normal percentage of oxygen in air is 21%, said reduction may reach 17% in certain cases only.

2) in cases of oxygen reduction in air resulted from bad ventilation in rooms or crowded places such as houses of worship & occasions, clinics & waiting rooms.

3) The need to increase oxygen concentration in air more than the normal rate for a limited period of time, in order to activate blood circulation, respiratory system, brain cells & other body cells.

4) Increase oxygen concentration in air in high rates and cool it at the same time in certain places such as ICU & medical care.

5) Adding a competitive advantage to air conditioner devices, i.e.

controlling oxygen level in the air of the room which contributes effectively in marketing the device.

Exploitation method

Adding a feature of controlling oxygen level in air of the conditioned room significantly helps in marketing this type of air conditioners by adding such a competitive advantage, which is not available in conventional air conditioners. Furthermore, the device of the present invention can be used in controlling oxygen concentration level in unconditioned places.

Detailed Description

One characteristic of Zeolite substance is absorbing nitrogen gas from air under pressure and releasing it after depressurization without any chemical reaction, combination or any change in Zeolite and nitrogen characteristics and composition.

Oxygen gas is extracted from the air outside the room as follows:

As shown in (figure 2), when electric current flows from power source (1 ), air compressor (4) will be on a mode as shown in figure (2) (the right side of the drawing). As an electric current passes through the circuit, an iron piece coiled with an electric wire (2) generates a magnetic force, thus the iron piece become magnetic which attracts iron base air compressor (4) downwards. Moreover, valve (7), which allows air passage from outside to inside in one direction only, is opened . Also, valve (9) that allows the

passage of nitrogen only from inside to outside in one direction is opened .

Moreover, valve (5), which allows the passage of extracted oxygen from air inside zeolite chamber to the tube (1 1 ), is opened.

When power cuts occur, air compressor will be on the mode as shown in the (eft side of figure (2). Moreover, when power cuts occur, the piece of iron (2) loses its magnetic force then compressor is pressed upwards via spring push force

(3)·

Compressor starts (4) pumping compressed air drawn from outside the room via tube (8) towards zeolite chamber (6) . Valve (9) and (7) are closed . Valve (5) is closed for a limited period of time (about 22 second). Said period may be increased or decreased (this is the required period for controlling air compression process inside zeolite chamber and ensure Zeolite absorption of nitrogen found in compressed air inside zeolite chamber (6). Valve (5) is opened after zeolite absorption of nitrogen found in air, in order to allow the passage of extracted oxygen to the tube (1 1 ) while keeping valve (7) and (9) closed. Extracted oxygen gas passes through tube (12) that pumps said oxygen towards crystal (4) (as shown in figure 1 ) which at the same time pumps air that is drawn from the room towards spiral Freon tubes (5) (as shown in figure 1) for cooling. Therefore, extracted oxygen is pumped with the air towards Freon tubes to cool both of them and push them back towards the room.

Results of power flow and outage are as shown in figure 1 , as follows:

In case of power outages

Compressor (4) pushes air towards zeolite chamber (6). Valves (7) & (9) are closed. Valve (5) is closed also for a limited period of time that allows zeolite to absorb nitrogen gas, after that valve (5) is opened to allow passage of oxygen only to tube (12).

In case of power flow

Compressor (4) is pulled downwards and valve (9) is opened to allow nitrogen gas release through the tube (10) outwards the room to allow zeolite chamber ventilation (6). Valve (7) & (5) are opened. Compressor (4) is ready for pumping new amount of

air (that is drawn from outside the room via tube (8) into zeolite chamber (6) in case of power cut again.

Thus, after power flow and outage, amount of oxygen gas is pumped to the tube (12).

Two compressors may be provided, in which the passage of electric current is interchangeable between them. In other words, in case of disconnecting electric current from the first compressor, electric current is connected to the second compressor, then when connecting electric current to the first compressor electric current is disconnected from the second compressor via timer contactor. This ensures oxygen flow continuously to the tube (12). This is because in this case where the first compressor compresses air, the second compressor discharges nitrogen gas and is ready to compress new amount of air as well. When the second compressor compresses air, the first compressor discharges nitrogen gas and is ready to pump new amount of air inside zeolite chamber. Therefore, all the time one of the two compressors compress amount of air inside zeolite chamber, which ensures continuous oxygen flow to the tube (12).

By the same way, any number of air compressors can be used by dividing them to two groups and distribute electric current between said groups interchangeably via one timer contactor. In this case one can ensure that air can be pumped inside zeolite chamber as well as oxygen gas extraction by one of the two groups any time.

Function of Oxygen sensor as shown in figure 2

The sensor measures oxygen concentration rate of air inside the conditioned room. Added to this, it controls closing the electric circuit, operating oxygen extraction process as well as pumping it into the room, opening the circuit and discontinuation of oxygen extraction process.

Running and stopping oxygen extraction process depends on maximum and minimum oxygen concentration level inside the room.

When oxygen level is reduced in the room, sensor closes the circuit and starts the extraction process of oxygen then pumping it into the room. In contrast to this, if the concentration level of oxygen increased more than the desired level, said sensor open the circuit and stops oxygen extraction to ensure not pumping more oxygen in the room. Therefore, oxygen concentration level in the room is controlled.
