The invention relates to a new solar thermally driven system that meets the heating and cooling demands of buildings. The system consists of a reversible absorption cycle which operates as a single effect absorption cycle in the cooling mode and as a heat transformer in the heating mode. Components of both cycles are the same, only the flow direction inside the system changes. In thermally driven systems, solar thermal collectors convert solar energy into thermal heat which can be used to run a thermally-activated device. Different types of thermally driven systems are available on the market, but among them, absorption systems are the most mature technology and are commercially available. The thermal collectors mostly used in solar absorption installations are flat plate or evacuated tubes. These thermal collectors produce hot water to drive the absorption machine in summer and produce chilled water. However, the hot water temperature obtained in winter with these solar collectors is too low to directly feed conventional heating systems but also is too low to drive the absorption machine in order to produce a higher temperature water stream to feed the heating system. So, in winter the hot water produced in the thermal collectors is heated up in a boiler before to feed the heating units. The invention proposes a new reversible solar driven absorption machine that in summer it would work as an absorption chiller, as the machines that we can find on the market today, but in winter it would work as a heat transformer. As heat transformer the absorption machine cycle can be driven with a heat source temperature of 40 °C to produce hot water at 60°C at an ambient temperature of 0°C. Furthermore, the lower the ambient temperature, the lower the activation temperature of the machine and higher the machine heating power. Components of both cycles are the same, only the flow direction inside the system and the connection with external devices changes. To allow the reversibility of the equipment and its operation in winter a new working pair, ammonia/lithium nitrate, has been selected because no rectifier is required and it does not present problems of refrigerant freezing at low condensing temperatures when the cycle operates as a heat transformer.

Producing PE125 using GRAFTALEN™ MP-UHHD. Consumer properties, which should be taken into consideration: 1) The unique toughness of the material (the highest rate of all known polymers), namely, Over 160 kJ/m2 2) High abrasion resistance 3) Low friction coefficient (self-lubricating) 4) High resistance to chemically aggressive reagents (media) 5) High creep resistance (geometric stability) Ordinary way - This type of process is quite expensive. Production of PE125, in compounding with bimodal PE100, from 8 to 45% of supermolecular polyethylene is injected, reaching dispersion by multiple compounding (4 stages) in an extruder cascade (XXXXX technology). GRAFTALEN™ MP-UHHD (alloy) is a MELT-PROCESSABLE concentrate of UHMWPE on an HDPE matrix. As HDPE, you can choose the most affordable HDPE (pipe) grade. To obtain polyethylene according to the standards PE125 (with a minimum strength indicator MRS> 13.8-14 MPa, in comparison PE100 has MRS only 10 MPa), a significant improvement in the resistance against hydrostatic pressure is required. For a conventional bimodal HDPE, this indicator is difficult to achieve, since it directly correlates with the impact strength/density indicators and with simple extrapolation, it turns out that the required indicator for PE125 simply does not reach the bimodal HDPE matrix. Another problem - the difficulty in maintaining the geometric stability of the pipe (the thickness at the top of the pipe is often less than at the bottom) due to the sagging effect (the phenomenon of the gravitational flow of a polymer melt). This phenomenon is more pronounced for thick-walled pipes. The specific blend of HDPE with UHMWPE allows solving these problems above.

Now, we have with you the all chances to create a unique company for implementing worldwide of a new science-intensive technology with many applications (see below). I invite you to participate in realization of this ambitious project in any capacity. Agree that far from often appears a new production company, when at the time of its creation becomes clear that it has all chances to become a world leader in its future activity. This is possible, obviously, only in the case that the basis for the activities of such a company will be the unique science-intensive know-how, the implementation package of which already exists. This is the case here for your consideration. The author of this letter (further - the author) recently completed his years-long work on the information-software package of materials (ISPM) on implementing a new science-intensive network technology with many applications called "Information technology of automation of control of discrete technological and information processes (IT AC DTIP)", the founder of which he is. With the presentation of both the technology itself and the ISPM for its implementation, you can familiarize here: https://www.slideshare.net/michael_burlakov/presentation-of-it-ac-dtip . More detailed information on this project you can learn from two English-Russian sites of the author:"Promotion Center of IT AC DTIP" (http://dtip-burlakov.com/en) and "Implementation Center of IT AC DTIP" (http://dtip-optim.com/en/main). I would like to draw your attention to the fact that this ISPM includes 11 multilingual optimizing software tools in the ordinary and network performances that allow to provide international network outsourcing services on optimal controlling the discrete processes for many purposes. So, for practical implementation of this technology, there are not required at all the financial investments for working out necessary for this means, since the latter ones already exist.
