Optimal planning of absorption refrigerating machine and cooling tower systems.

Performance of a Solar LiBr - Water Absorption Refrigerating Systems

Up to now, the production of the cold is undertaking mainly by the classical way of compression refrigerator cycle. The cycle need an electrical power or mechanics expense for the training of the compressor and the C.F.C for their functioning. Most of the C.F.C impoverish the layer of ozone and participate with a considerable manner, to the increase of the sere effect, then to climatic changes....

Enumeration of Legionella pneumophila in cooling tower water systems.

Legionella pneumophila, the causative agent of Legionnaires' disease, is known to colonise and frequently grow in cooling tower waters. Disease is acquired by inhaling aerosol contaminated by legionellae. Determination of the count of Legionella pneumophila in cooling tower waters may, therefore, be useful for risk assessment. In our survey, 103 water samples from 50 cooling towers were examine...

Study of Degradation of Dry Cooling Tower Performance under Wind Conditions and Method for Tower Efficiency Enhancement (RESEARCH NOTE)

Wind affects adversely the cooling tower thermal performance. A field investigation was carried out to study the thermal performance of Heller cooling towers under wind conditions, involving measurement of wind velocity and its direction around the cooling tower, and obtaining water flow rates and temperatures at the cooling tower inlet and outlet. Results show that air suction at the tower top...

An Improved Modular Modeling for Analysis of Closed-Cycle Absorption Cooling Systems

A detailed modular modeling of an absorbent cooling system is presented in this paper. The model including the key components is described in terms of design parameters, inputs, control variables, and outputs. The model is used to simulate the operating conditions for estimating the behavior of individual components and system performance, and to conduct a sensitivity analysis based on the give...
