The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
ISO 7345:1987, Thermal insulation一Physical quantities and definitions
ISO 13790, Energy perfrmance of buildings一Calculation of energy use for space heating and cooling
For the purposes of this document, the terms and definitions given in ISO 7345:1987 and the following apply.
electrical energy used by technical building systems for heating, cooling, ventilation and/or domestic water to support energy transformation to satisfy energy needs
Note 1 to entry: This includes energy for fans, pumps, electronics, etc. Electrical energy input to the ventilation system for air transport and heat recovery is not considered as auxiliary energy, but as energy use for ventilation.
gas, liquid or solid fuelled appliance designed to provide hot water for space heating
Note 1 to entry: It can also be designed to provide domestic hot water heating.
oil or gas boiler designed to make use of the latent heat released by condensation of water vapour in the combustion flue products
Note 1 to entry: A condensing boiler allows the condensate to leave the heat exchanger in liquid form by way of a condensate drain.
Note 2 to entry: Boilers not so designed, or without the means to remove the condensate in liquid form, are called ‘non-condensing’.
non-condensing boiler which can work continuously with a water supply temperature of 35℃ to 40℃
boiler with the capability to vary continuously (from a set minimum to a set maximum) the fuel burning rate whilst maintaining continuous burner firing
boiler with the capability to vary the fuel burning rate stepwise whilst maintaining continuous burner firing
boiler without the capability to vary the fuel burning rate whilst maintaining continuous burner firing
Note 1 to entry: This includes boilers with alternative burning rates set once only at the time of installation, referred to as range rating.ISO 13675 pdf download.
