CEN/TC 228 Heating systems and water based cooling systems in buildings

European Norm

Scope

This standard specifies design criteria for heating systems in buildings using electrically driven heat pumps for heating and cooling alone or in combination with other heat generators. Heat pump systems considered include (see Table 1):
— water – water;
— water – air;
— brine – water;
— refrigerant – water (direct expansion systems);
— refrigerant – refrigerant;
— air – air;
— air – water.
Other energy sources such as waste water, massive absorbers and ice storage systems may also apply, as well as heat pump systems using more than one energy source.
This standard takes into account the heating requirements of attached systems (e.g. domestic hot water) in the design of heat supply, but does not cover the design of these systems. This standard covers only the aspects dealing with the heat pump, the interface with the heat distribution system and heat emission system (e.g. buffering 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 included in this standard. Systems designed primarily for cooling are not within the scope of this standard.
