Description

Air Conditioning with a closed path system
Specifications
Background of the Invention:
The invention relates to the disclosure of air conditioning -and Heater- for home, office and open spaces. The system incorporates a thermally isolated box that contains part of closed path of Metal tube having high thermal conductivity that is filled with fluid having certain physical properties (antifreeze). And that part of metal tubing is placed in contact with a medium which has been pre cooled or heated using for example ordinary household appliances such as a refrigerator, an ice maker (or dry ice when there are appropriate conditions) or home boiler or any available means of heating. The system can be further enhanced by using thermoelectric cooling/ heating to prolong the medium's thermal energy storage.
Technical condition of the existing air conditioners that depend on CFCs - Freon "R-12" which is the most commonly used in the field of home and office air conditioning
Saudi Electricity Company showed that the wall conditioners using Freon consume different capacity (12000-24000 BTU) electric power ranging from 2000 to 4000 watts / hour (2-4 kW / h)
Given the health warnings of Freon or R-12 issued by environmental and health organizations, gas particles when leaked or secreted from the air-conditioner can cause damage to on the ozone layer and cause chronic health issues on human life causing allergic reactions, shortness of breath and even strokes. Moreover, the tubes in the air- conditioning unit carrying Freon are prone to leak especially if beyond three years of use.
The major oil consuming countries in the world are actively making significant efforts to secure stable sources of energy, and activate the Tokyo Protocol, which deals with the reduction in the discharge of greenhouse gas in order to minimize global warming. It is expected that the international pressure regarding the specific use of the energies will further increase in order to achieve global energy efficiency.
In Saudi Arabia, for example, month of August 2014 recorded unprecedented hike in electricity consumption in Saudi Arabia, a new historic record, where consumption jumped to 56,500 megawatts, an increase of 7.7% for loads peak recorded during the summer of Specialists in energy say: this great figure in the growing electricity consumption in KSA is an indication of the growing domestic consumption of energy, which runs at very high rates compared to many countries in the world. They noted that the official statistics indicate that Saudi Arabia leads the world in the size of the domestic consumption of energy, where the average per capita consumption is twice the global average, with an average annual growth rate of more than 5% per annum. Despite the significant growth in demand for energy due in part to rapid economic growth, urban development and increase in population in the Kingdom, a large part of it is due to the waste and inefficiency in consumption, which results in an enormous burden on the electricity power plants to meet ever increasing energy demands that can cost up to hundreds of billions of Riyals.
According to the latest statistics, the residential home/building sector in the KSA is consumes more than 80% of the total electricity produced where air conditioning contributes about 70% of the total usage. With an annual expected growth rate of up to 12%, about 70% of the buildings in Saudi are not thermally insulated. It is estimated that the average per capita consumption in the Saudi is twice the average global consumption, while Saudi Arabia depends on converting over four million barrels of oil to electricity which is one of the highest levels of consumer in the world.
From the above, it shows that if the goal is to reduce the amount of conventional fuel that is burned for the purpose of producing electricity, and to reduce the environmental risks posed by the use of Freon, it is incumbent on us to look for new products that are more energy efficient and rely not on current technology that is energy thirsty and rely on fossil fuel and poses a wider threat to the planet and its inhabitants.
Add to all, the current air conditioners are very heavy, fixed, bulky, and not movable, makes a lot of noise and vibration, and cannot be used outdoors where it causes pressure on the compressor which may cause system damage.
General description of the invention:
This invention's goal in the light of the above is to provide an air conditioning system (cooling / heating), that uses less energy, and does not use conventional cooling gases CFC runs quietly, does not cause noise, has a lighter weight, very mobile, less expensive, and can be used outdoors.

It can be enhanced by using thermoelectric cooling/ heating.
It consists of several basic parts as follows: a pack of cooling or heating filled with fluid (such as blue Gel) or (PCM Phase-change material) (1) and placed in the thermal insulated box (2), fan (3) pump (4) connected to a Metal tube having high thermal conductivity , filled with fluid having certain physical properties -antifreeze- (5) and connected to the Heat exchanger -Optional- (6), and the pump also connected to thermostat (7), filters (8), and finally condensation collection tank (9).

Detailed description:
And now described in detail Air conditioning system which uses a closed path, and it depends on the means of cooling/ heating have been prepared in advance, according to the drawings attached as an example of the application of the invention see Figures 1 , 3 and 4: the system consists of several basic parts as follows: a pack of cooling or heating Filled with fluid (such as blue Gel) or (PCM Phase-change material) (1) and placed in thermal insulated box (2), fan (3) pump (4) connected to a Metal tube having high thermal conductivity , filled with fluid having certain physical properties -antifreeze- (5) and connected to the Heat exchanger -Optional- (6), and the pump also connected to thermostat (7), filters (8), and finally condensation collection tank (9).
Given the attached drawings, at system startup first we put a previously prepared means - cooling or heating - 1 in the thermal insulated box 2, and fan starts to work 3, and pump also 4 fluid in the pipe metal 5 begins to rotate in a closed path as shown in Figure 1 , and the heat exchanger 6 exchange the air with the atmosphere of a room or office (the place to be conditioned) we get a goal from the system cooling or heating
If using the system in a closed area such as room or office, upon reaching the desired room temperature, the pump will stop working by thermostat 7, cooling or heating stops until the change in ambient temperature is detected as the fluid in the pipe / tank located in the thermal insulated box has gained more heat or cold during time the pump turned off. The pump will then re-work effectively to reach the desired temperature.
The air to be cooled or heated passes through the filters 8 that purifies, refreshes and cleans the air, before passing through the heat exchanger.
Furthermore, there will be condensation as a result of hot and humid air passing through the heat exchanger, which will be collected and discharged into the condensation collection tank 9 or directly through the hose to the outside. To specify the volumes and size of the main parts of the system are estimated by Knowing the cooling /heating load by British units - for example - and the difference with temperature desired to be achieved, and that by determine water flow rate within those pipes so that we can determine the appropriate diameters and appropriate speed
Then we specify ton of cooling capacity to determine the flow rate inside the pipe that achieves when it passed within the heat exchanger cooling air equivalent to one ton of cooling so that we can know the number of units of air circulation for different areas if we have identified all of them by ton of cooling capacity
Although it has been detected the favorite models of the present invention for the purposes of demonstration, the experts in this field will realize that you can make adjustments and additions and multiple substitutions, without moving away from the field of the invention and it essence, as are disclosed in the accompanying elements of protection.
