Air conditioning systems in buildings consume a significant part of the world’s energy, and yet there are cases wherein users not satisfied with quality thermal environment. Examples such special sports halls, which require different conditions within single zone. Thermal diagnostics for can be used to diagnose problems. The aim paper was analyse effectiveness ventilation cooling hall cubature ...

Hospitals represent approximately 6% of total energy consumption in the utility buildings sector. Heating, Ventilation and Air Conditioning (HVAC) systems are the major part of electrical energy consumption at the hospitals. The air-conditioning system is responsible for around 70% of total electricity consumption. Electric motors and lighting systems in a hospital represent approximately 19% a...

Testing the quality of manufactured products based on their sound expression is becoming popular nowadays. To maintain low production costs, testing processed at end assembly line. Such measurements are affected considerably by factory noise even though they performed in anechoic chambers. Before designing control algorithm a convolutional neural network, we do not know influence success rate t...

The exploitation of natural ventilation is a good solution to improve buildings from an energetic point of view and to fulfill the requirements demanded by the thermohygrometric comfort and the air quality in enclosed spaces. Some past researches demonstrated how some devices, useful to this purpose, follow the principles of solar chimneys and are able to move air masses while exploiting the Ar...

The Air conditioning system satisfies the various space conditions required for the comfort and industrial air conditioning. Now days demand for AC system applications are increasing and include the areas of application like apartment buildings, banks, office buildings, industrial plants, schools, restaurants etc. This growing demand for air conditioning system forced manufactures to develop su...

The energy conservation potential of the heat pipe based heat exchangers (HPHXs) was studied in this research. To this end, a typical climate chamber as the representative of an air conditioning system was established. The performance characteristic of a typical eight-row HPHX was obtained based on the one week operation (168 h) to determine the performance characteristic curves. The coil face ...
