Evaluation the structure of panel wall type residential buildings from the fire salety point of view

Abstract...

There are no differences between several build structure systems of panel wall type residential buildings from the fire point of view. Problems with fire safety this houses has not source in good or worse structure type, but in time of those designing and measure of respect to fire protection standards valid at construction time.

Problems of air tightness of windows

Abstract...

Heat losses, connected to natural ventilation of buildings, are low by new types of windows and doors with higher tightness of cracks. Infiltration is under ventilation rates needed for extraction of water vapor, formaldehyde, radon and other contaminants. Article present effective leakage coefficients for comrade windows and doors, established by measurements in laboratory and in situ. Example of estimation the windows leakage coefficient value for hygienic rate of ventilation air is added.

Refrigerants for Air-Conditioning

Abstract...

Actual trends in refrigerants for air-conditioning cooling. Refrigerant is judged as a working matter and in context with the cooling cycle. Advised is extended use of waste heat and mentioned is selection of proper refrigerant and cooling cycle from this point of view. Introduced is state of work on new Czech act for protection of ozone layer against depletion.

Summer indoor thermal comlort Simulation by using wallboard with phase change material

Abstract...

ln the summer indoor climate usually reaches higher temperatures and there is not thermal comfort for people activity. The heat gains from any electrical devices can make situation worse and the problem is usually solved by cooling system. But it can be solved by applying special treated wallboards. The special treated wallboards can absorb ten times more heat than conventional wallboards and it can retard growing temperature in the room. If there is a cooling system necessary, there could be design cooling system with lower power and save a third of electric energy. This paper show results of simulations of summer indoor climate by computer system Ansys in the room with applying of conventional and treated wallboards.
