Design of jet axial-flow fan for longitudinal ventilation of tunnels ![]() Abstract...A summary of results from the development of axial-flow fans for longitudinal ventilation of tunnels is presented. The construction of these fans was described in VVI1/97, pp. 37 - 38. | Cyrus, V. | 98 - 100 |
Plastic piping in heating ![]() Abstract...The paper deals with merits and drawbacks of plastic piping applications. Basic characteristics of plastic pipes are given and on their basis the usability of plastic piping is discussed. | Bašta J. | 101 - 106 |
Calculation procedure lor CALMAC cool storage ![]() Abstract...Economical operation of a cooling device in air-conditioning application with water cool storage is described. An example of numerical solution is presented. | Chyský P. | 107 - 108 |
Effect of interior space zoning on smoke spreading ![]() Abstract...The paper deals with smoke spreading in a building which is on fire. The effect of building ventilation and zoning on the fire development is described. More details about fire propagation in a multi-fIoor building and a church are given. | Kupilík V. | 109 - 111 |

Low-sulphur heating oils - fuel with good prospects ![]() Abstract...Before building a new heating system or reconstructing a boiler room the decision about heat source must be taken. The paper aims to make the choice of energy source easier, particularly for the householders without natural gas supply. | Šponar P. | 126 - 128 |
On the static suction head of a pump ![]() Abstract...Energy conditions in a suction system are discussed with respect to the cavitation properties of a pump. A general instruction for the static suction head evaluation is described. The static suction head determines the insta/lation of a pump in terms of its height above the lower reservoir level. The evaluation is demonstrated on three practical examples. | Bláha, J. | 129 - 130 |
