1c Describe what type of testing does the R&D result need?

Detailed comment

At present, the research result consists in a technical patented solution and a functional model for emphasizing the phenomena of cold and hot, by processing thermodynamically the pressurized air. For the physical achievement of the model, we used the material base existing in laboratory where, for lack of a fan, we used a classical compressor with pistons at 7 bar; the low pressures (1.5 – 2.5 bar) were got by means of a pressure rectifier.

For testing industrially the research result, it is necessary to cover the following stages:

- additional research, design and achievement of a functional model for low pressure source (pressure fan/air blower/low pressure mini-compressor);

- design and achievement of the functional model for the installation;

- testing of the functional model, and also:

- verification of the operating capabilities of the mechanical-electric-

pneumatic circuit and automation circuit;

- verification of refrigerating and thermal efficiency;

- verification of energy quality (clean energy).

1d. What is the time needed for testing?

Time period for testing is estimated to be  90 working days
1e. What is the cost needed for testing?

The costs related to the additional research, functional model design and achievement are estimated to be 95000 euros.

The costs related to the functional model test are estimated to be 25000 euros.

SECTION 2: Current Stage of Development

2a To what extent does the development team have technical resources for supporting the production of a new product? (Researchers, human resources, hardware, etc. )

The research-development team has most of the human resources for providing the new product manufacturing. Specialists required for completing the team are from the field of generation of low pressure compressed air (pressurized air).

The research result is the consequence of some research and experimenting activities performed by a specialist team, willing to realize these results further on.

In this respect, the specialist team is available for technical advice, so as the potential partner could manufacture this new product.

2b What are the technical issues that need to be tackled for full deployment, if needed?

Launching the product into mass production, on the basis of a patented technical solution, implies covering some stages of technical and technological development:

- Prototype designing;

- Prototype achievement and testing;

- Serial product designing;

- Flow manufacturing technology designing;

- Manufacturing technology achievement;

- Serial product testing and certification.

2c What additional technical resources are needed for the production of this new product?

The equipment from the installation structure, for which it is necessary to find a technical solution, is the pressurized air source (1.5 to 2.5 bar).

For this purpose, there are imposed conditions such as: small overall dimensions, energy efficiency, noiseless in operation, reliability, possibility to be supplied from the mains (220 V/50 Hz). These conditions can be fulfilled by special equipment, like a pressure fan, an air blower or a low pressure mini-compressor, for which additional researches by specialized companies in the field are necessary.

2d Overall assessment of the current stage of technical development.

Detailed comment

The phenomenon of separating the energy of an incident flux of compressed air into a cold air flow and a hot air flow, in a vortex field, is known in the current stage of technical development, and the used apparatus (pneumatic vortex generators) are manufactured worldwide by specialized companies.

A functional model of the air conditioning installation is achieved at ICMET Craiova, where the phenomenon of energy separation in vortex field is emphasized even at low pressures (1.5 to 2.5 bar) of the incident air flux.

When achieving the model, a classical compressor was used as pressure source, with pistons at 7 bar, significant overall dimensions, and the low pressures (1.5 to 2.5 bar) were got by means of a pressure reducer.

The equipment from the installation structure, bringing some uncertainty, is the pressurized air source (1.5 to 2.5 bar), for which there are imposed conditions such as: small overall dimensions, energy efficiency, noiseless in operation, reliability, possibility to be supplied from the mains (220 V/50 Hz). These conditions can be fulfilled by special equipment, like a pressure fan, an air blower or a low pressure mini-compressor, for which additional researches by specialized companies in the field are necessary.

Installation operation in automatic cycles, controlled by sensors and specialized electronic circuits, raise no problem in being assimilated. Actually, they are similar to those ones which fit out the present classical air conditioning installations with Freon.

Consequently, as regards the operation parameters, technical performances and technological manufacturing technologies, the new product is achievable, and by its promotion on the market it can replace the present Freon air conditioning installations we find at home, at the office, in workshops etc.

SECTION 3: Deployment

3a Define the demands for large scale production in terms of
  • Materials

The purchase of the materials and component apparatus (mechanical, pneumatic, electrical, electronic) for large scale production can be done from the current manufacturing of specialized companies.

For assuring the design and for personalizing the product, we consider necessary to design and assimilate in manufacturing an enclosure (special boxes) for assembling the installation components.

This assimilation of the pressure fan/air blower can be done only after performing some additional research.

  • technologies, tools, machineries
For large scale production it is necessary:

- endowment with a manufacturing line (assembling) with about 30 work stations;

- final station for control and product acceptance.

  • Staff effort
For putting into large scale production, we assess the following demand for personnel :

-          working personnel  for the manufacturing line: 30 persons;

-          service personnel  (supply, storage, handling, delivery): 7 persons;

-          technical personnel: 6 persons;

-          marketing, administrative personnel: 3 persons.

SECTION 4: Overall Assessment

1 What is you overall assessment of the technical feasibility of the research result?

The technical parameters which are imposed to the new product are achievable, they are within the range of normal values, such as:

- pneumatic working pressure: 1.5 to 2.5 bar;

- general temperatures: cold air (-10oC to +20oC) and hot air (+21oC to +60oC);

- refrigerating and thermal power: 1000 to 12000 Btu/h (300 – 3500W).

Additional researches require the pressurized air source (1.5 – 2.5 bar), for which specialized companies in the field will be used.

Product testing will raise no problem; there are authorized thermodynamic laboratories for this where, besides the functional parameters, the quality of the existing air will be assessed. In conclusion, the project can be technically considered as one with minimum risk, at the same time having a support from the commissions and forums for environment protection for implementing it.
