Heating period 1998/99 in Prague from the point of climatic variables view

Abstract...

The article presents integral information on the course and character of heating period 1998/99 in Prague. In addition to basic climatologic values indispensable for the heat requirement calculation for heating even further climatologic data supplementing the weather character of this period in the whole Czech Republic connection are evaluated in tables and graphs on the basis of the climatic variables measured by the observatory Prague-Karlov.

Environmental technique equipment and atmosphere protection

Abstract...

The contribution deals with atmosphere protection problems from the point of environmental technique view. Basic information on the transfer of the contaminating substances in the atmosphere and on dispersion studies as a part of EIA process are indicated. The importance and wide utilization of technologie filtration is emphasized as the most effective way of solid matter separation from carrying gas.

Technical-economic aspects of apartment houses ventilation

Abstract...

The apartment buildings with well insulated enclosing shell show an increased portion of heat consumption for ven­ti/ation air heating. The article presents an overview of thermal-technical properties of bui/ding structures including windows and doors according to standards of the Czech Republic, EU countries and USA. The requirements con­cerning the venti/ation intensity in these countries are also indicated. As an example the yearly costs of natural venti/ation wit intensity of 0.5, 1 and 1.5 1/h of an apartment house with 20 apartments are determined and the savings and the pay-back period are quantified for the individual venti/ation equipment and for central ventilation with heat recuperation equipment.

A new trend of administrative building air-conditioning

Abstract...

The contribution indicates capacity and design parameters of cooling ceilings. The energy consumption amounts of year-round operation of air-conditioning equipment with proportional air f10w and of air-conditioning equipment with cooling cei/ings are compared. The contribution is based on knowledge acquired during design praxis with cooling mats of the firm Nickel.

Calculations of moist air states by means of computer with graphical output in h - x diagram

Abstract...

This software replaces a work stili using diagrams and tables. In addition it makes accurate calculations as it allows to enter the arbitrary value of the moist air pressure and eliminates any influence of an inaccuracy in reading from diagrams and tables. ft utilizes combinations of exact and interpolative solutions, which make any given moist air pressure possible to enter state from different pair of properties. The software contains constants of the moist air within the range of the total pressure from 40 to 200 kPa and within the range of temperature from -35°C to the boiling temperature of water for any given total pressure. AII outputs from this software are numerically and graphically parallel.
