13 Space heating and cooling Optimization ot generator temperatures In the heat 96105434 operated absorption cycle using four types of aqueous salt solutions Malik, 1. H. and Siddiqui, M. T. Energy Convers. Mgmf., Apr. 1996, 37, (4), 433-44s. Economic analyses of biogas, liquefied petroleum gas and solar collectors for optimizing generator temperatures in the absorption cycle, using aqueous solutions of LiBr, LiBr-ZnBr,, LiBr-ZnBr,-LiCl and LiBr-ZnCl,-CaBr, salts, have been carried out for a wide range of operating conditions. An ordinary collector, with two glass covers, and an evacuated-tubular collector have been selected as the sources of energy for providing hot liquid in the generator of the absorption cycle.

Liu, M. et al., ASHRAE Trans., 1995, 101, (2), 688-700. The authors maintain that building energy consumption can be substantially reduced after implementing improved operation strategies that are a scientific refinement of traditional operation and maintenance measures. This involves resetting the cooling deck or heating deck temperature to achieve maximum energy efficiency without compromising indoor air quality and comfort,
Yoon, D. W. et al., Ewiromnent In!., 1996, 22, (3), 309-314. Indoor nitrogen dioxide concentrations in 19 ice skating rins in the greater Boston area were monitored for one week each month, over a four-month period. Nitrogen dioxide was selected as an indicator of indoor air quality, and NO samplers were placed in two locations within each rink. Rinks ,i, er NO, levels (in excess of 200 nL!L), under normal operation, in with lug the first monitoring week were mitigated with changes in ventilation system operation in the subsequent months. After the first monitoring period, only two rinks had NO, levels above 200 nL/L. It was suspected that high levels in these two rinks may have been related to improper ventilation. High NO, concentrations were found in the ice skaing rinks with ropanepowered ice resurfacers, other studies indicate that combustion Puels can also result in elevated indoor concentrations.

Reports on the completion of the Budapest’s Kelenfold district heating power plant, one of the first gas turbine based repowering projects in the former Eastern Europe. The project illustrates the country’s growing acceptance of efficient gas turbine based power systems. The new combined-cycle power plant is expected to significantly improve the power and district heat supply in Budapest, allowing more efficient energy utilization while reducing environmental pollution.

Patnaik. V. and Perez-Blanco. H. Int. J. Heat & Fluid F[ow. Feb. 1996. 17, (1);63-70. Wavy flows, an important aspect of falling film absorption in refrigeration systems, are difficult to describe analytically because of their transitional regime. Within the wavy-laminar flow regime, high-frequency capillary waves are known to exist below a Reynolds (Re) number of 200. Above the critical Re, inertial waves driven by gravity, known as roll waves, can exist. These low-frequency waves, observed in an experimental absorber, were identified via image-processing studies of the falling film.

Thermal performance of an evaporatively cooled building: Parametric studies Maiya, M. P. Int. J. Energy Research, Jun. 1996, 20, (6), 465-481. 96105452
A single-story office building in a hot and dry climate is modelled for evaporative cooling. The counterflow cooling tower is modified to precool the tower inlet air by the tobver exit air in a heat exchanger. Centralized evaporative air cooling, using the modified cooling tower, and roof evaporative cooling are considered to provide comfortable living conditions in the space. The thermal performance of such a building is analysed for various operating parameters. The study indicates that centralized evaporative air cooling is feasible, to maintain near-perfect comfort conditions in hot and dry climates. Modified cooling tower and roof evaporative cooling further enhance the scope of evaporative cooling for comfort applications. 96105453
