Data represent values of heat losses officially accepted by Minenergo Order 325 as norms. Those values represent heat flux that is legally affirmed to be emitted per meter during an hour by steel pipe of district heating system with water as a heat carrier.
A data frame with 17328 rows and 8 variables:
Identifier of data source: identifiers suited with
glob t?p? mean appropriate table ?.? in
Minenergo Order 325;
identifier sgc means that values are additionally
postulated (see Details).
Year depicting the epoch when the pipe is put in operation after laying or total overhaul.
Type of pipe laying depicting the position of pipe in space. Only five types of pipe laying are considered:
Logical indicator for pipe regime: if
TRUE pipe is
operated more that
5000 hours per year.
Identifier of insulation that covers the exterior of pipe:
foamed polyurethane or analogue
Nominal internal diameter of pipe, [mm]. Type:
Operational temperature of pipe, [°C]. Type:
Heat flux emitted by every meter of pipe during an hour, [kcal/m/hour].
Data is organized as a full factorial design, whereas for some factorial combinations Minenergo Order 325 does not provide values. For that cases values are postulated by practical reasons in Siberian cities and marked with source label sgc.
Usually the data is not used directly. Instead use function
