Heating period 2000/2001 from the point of climatic quantities view

Abstract...

The article represents an integral information on the course and character of the heating period 2000/2001 in Prague. From the climatic quantities measured at the observatory Prague-Karlov were determined the values of quantities necessary for the calculation of the heat demand for heating and the climatological data illustrating the weather character of this period in the Czech Republic.

Utilisation of some notion about air flow in air conditioned space

Abstract...

Presented are experimental data about turbulence in jets from ventilation air outlets. Results are useful for prediction of air movement cooling effect on human body in air conditioned space. Tezis are based on CEN recommendation for evaluation of indoor climate in ventilated spaces.

Ventilation ductwork as heat exchanger

Abstract...

Instead of installing the heat exchanger into the voluminous ventilation equipment the heat exchanger can be installed in the ventilation ductwork in the future. This design solution brings space savings in the ventilation machine room. A draft design of chamber heat exchanger is indicated for dwelling ventilation.

Recent news from the operation of environment engineering equipment I.

Abstract...

Significant changes of methodology and position of activity were not even avoided by the operators of environment engineering equipment. The operators had also to adapt themselves gradually to the rising trend of the transition to the methodology of facility management and to the fulfilling of the discriminating customers requirements by their qualified approach to equipment operation and maintenance control. They have to be able to overcome even the consequences of some faults caused by design or erection defects.

Some remarks concerning the calculations of harmful substances concentrations at the outlet of combustion gases exhaust from gas appliances to fasade

Abstract...

The article deals with problems of combustion gases exhaust ending to fasade – turbo-boiler. The calculation procedure has not yet been followed through to binding methodology. The author demonstrates by an example that it is possible to solve this problem.
