European Stars And Stripes (Newspaper) - January 10, 1987, Darmstadt, Hesse                                Cooling cars with recycled heat by Pamela Symona novel air conditioning system which can Cool automobiles without additional fuel operating expense or Strain on the car motor is currently under production by an israeli company conventional car air conditioning consumes 10-20 percent of a car s Luet and strains the motor id such an extent that Small cars normally can t be if conditioned the new system developed by scientists at he engineering faculty of Tel Aviv University is being produced by Galit advanced technology. The Galit system replaces the conventional compre for method with an ejector a Small pump and a heat exchanger. Conventionally car air conditioning relies on the car s compressor driven by he engine Shaft which naturally receives More Power when the car is travelling Laster. Therefore when a car a bogged Down in sweltering bumper to bumper traffic and he engine Terri Nerater soars the air conditioning unit has of be turned off to avoid overheating the engine Stock and destroying it. The new israeli method has nothing to do Wilh the compressor therefore ii does not depend on Power nor the engine Shalt. It draws its main Power from the hot water thai flows from the motor to he Radiator. This water is circulated by a water pump into which a liquid refrigerant freon 114, is pumped. The air conditioning unit consumes Only the amount of heat required to operate it emitting the remaining heat via the Radiator. A conventional air conditioning system has a condenser in front of the Radiator and an evaporator inside the passenger compartment explains Yrja Kimchi manager of Energy products of galil advanced technology or the Sissum group who have the commercial rights to he product. We Don t touch these two parts. The evaporator located in the passenger Cabin operates under Low pressure and absorbs heal from the surroundings the ejector compresses hese Vapours to the pressure of the condenser where this heat along with the heat absorbed in the Generator is expelled from the  Kimchi believes that this system May Well revolutionize air conditioning of automobiles. Our system which pumps liquid instead of Gas takes Only about 70 Watts from the car gallery he says. Whereas a conventions air conditioner increases fuel consumption by Between 10 and 15 percent the ejector operated system uses no additional  apart irom fuel saving the new system greatly reduces the Load on the Radiator by utilizing the heat which normally enters ii. In act in the near future we will probably propose a smaller size Radiator for cars which install our system Kimchi adds. In Wing by Titan Kedmy Ismail Engineer have developed an unconventional or conditioning Tuttem  Wimch they toy mar  without additional fuel operating expel or to rain on the motor. The ejector operated unit can also heat up the passenger compartment of a car without the Nard to install a special heating Core. It eliminates the heating Core and circuit which Are used in cars with conventional air conditioners by utilizing the evaporator to heat the car the Gas in the system is run against the hot water bypasses the ejector and in sent to the evaporator in the passenger compartment. One flick of a Small switch and our1 coding system can heat i Mew explains. Except for lha Small circulating pump the ejector system has no moving parts which reduces the likelihood of breakdowns. The research team estimates that it can be installed for lha same Price or 10 percent cheaper than a conventions system. Al the moment it is applicable to engines from 1300 cd and up although Kimchi Hopes that possibilities for smaller cars will be developed later. At the moment a prototype completed four months ago and fitted under a Subaru 1300 cd Hood has proved the viability of the Cycle during the coming months Static and dynamic tests will be performed and Kimchi Hopes to hit the Market with a final commercial product towards the end of next year. Galil technology has invested about Naif a million dollars in the project with a lot More to  Bui there is Cash to be made in Cooling. Each year about 8 million cars Are made and sold in lha . In 1983,80 percent of hem were installed with air conditioners. According to Kimchi galil technology is today very close to a joint venture agreement with one of lha big air conditioner manufacturers in the United states. Even ii we penetrate 5 percent of the Market he notes that s a lot of air conditioners other applications for the ejector system include installation in Oil Road equipment like tractors bulldozers and agricultural machines thai us a lot of engine Power. The scope of the system May also a enlarged to include air conditioning military tanks and be adapted to Marine application. To tour from Tinnil High cholesterol level can be fatal by Larry Doyle United press International our of every five Middle Asa american men risk premature death irom heart disease because of unhealthy Levels of cholesterol in their blood government scientists say. The research based on a landmark study of More than 350,000 men found even moderate Levels of blood cholesterol boost the Odds of death irom heart disease and that the danger is present even in men who do not smoke or have High blood pressure. I think the numbers speak rather clearly Lor themselves or. Jeremiah Stamler a cardiologist irom Northwestern University said in a recent study. The optimal cholesterol level is 180, and 80 percent of this population is Over 160. They re All at risk to said. That s the lesson  other researchers reported an  drug called Lova statin cuts High cholesterol Levels by a third and could prove to be an effective treatment for people whose cholesterol Levels do no respond to changes in diet. Both studies were published in a special cholesterol Issue of tha journal of the american medical association in december. Cholesterol a family of fatty substances found in the blood is essential to the body s metabolism but also can build up inside blood vessel Walls causing a dangerous narrowing known As hardening of the arteries. Afong with smoking and High blood pressure cholesterol has been recognized As a major Lector in coronary heart disease which accounts for nearly Hall of the deaths in the United Stales every year. In 1973, the National heart lung and blood Institute launched a massive research program to fully examine causes and possible treatments of coronary heart disease. The eight year study. Multiple risk Factor intervention trial. Ca Jed Murfit. Involved 36t,662 men age 35 to 57 irom 18 . Cities. Stamler and his colleagues Analysed Murfit data and saturday january 10, 1967 found All cholesterol readings above 180 milligrams per 100 Millilitre a of blood were associated with premature death irom heart disease Wilh the risks getting More severe the higher the Reading. These findings support a Call Lor programs to reduce cholesterol Levels in the entire population Slammer said previous studies estimated each 1 percent drop in cholesterol will result in a 2 percent drop in heart disease. While cutting out laity foods will reduce cholesterol Levels in most people some do not respond to such dietary changes and require medication no drug currently available is Ideal Lor this purpose but another study in the Aua Puma indicated Lova statin May come dose in a study of 101 patients 40 my doses of Lova statin Given twice a Day reduced total blood  by 32 percent or to near Normal Levels with few Side effects. The drug appears to work by interfering with production o Tow density lipoproteins a dangerous form of cholesterol associated with atherosclerosis. The stars and stripes witha Erosco Page 17
