Ventilation for buildings - Metallic ventilation ducts - Requirements and test methods

This document specifies dimensions, tolerances and denomination for rigid metallic ductwork used for ventilation air conditioning of buildings including test methods and performance characteristics regarding strength and leakage for ductwork, ducts and fittings in laboratory conditions. The test methods, shapes, designs and performance characteristics are applicable for ventilation ducts with circular and rectangular cross sections. The leakage test methods are also applicable to other cross sections. This document does not include ductwork made from insulation duct board, which is covered in EN 13403 [6], non-metallic ductwork, covered in EN 17192 [7] and all components that have more functions than the transport of air for example fire dampers, filter units, air terminal devices handled in EN 1751 [8] and EN 15727 [9]. This document does not include requirements for the overall system design for the air tightness which is covered in EN 16798-3 [10]. On-site tests are given in EN 12599 [11].

Heating systems in buildings - Design of heat pump heating systems

This document specifies design criteria for heating and cooling systems in buildings using electrically driven heat pumps for heating and cooling alone or in combination with other heat generators. The heat pump systems considered in this document (source system/sink system) are listed in Table 1. For cooling purposes, energy source and energy sink can be reversed. This document also applies to other energy sources such as wastewater, massive absorbers, ice storage systems, as well as heat pump systems using more than one energy source. This document takes into account the heating requirements of attached systems (e.g. domestic hot water) in the design of the heat supply but does not cover the design of these systems. This document covers the aspects dealing with the heat pump, the interface with the heat distribution system and heat emission system, the control of the whole system and the aspects dealing with energy source of the system. Design criteria for reversible heat pump systems for heating and cooling are also included in this document. Table 1 - Heat pump systems used for heating (within the scope)
