Measuring Volumes

Danish Technological Institute 11 January 2005/Niels From/Per Henrik Pedersen

Abstract

This note deals with the measuring of net volumes in connection with the positive list and energy labelling scheme for professional kitchen cabinets.

The energy consumption should be measured according to DS/EN 441-9:1994 and the net volume according to DS/EN 441-3:1994 section 3.1 and 3.2, which correspond to prEN 23953-2:2003 section 5.2.2.

Background

The energy consumption is measured in connection with energy labelling schemes for kitchen cabinets. The energy consumption is measured according to relevant standards cf. below table.

The energy consumption is often seen in relation to the size of the cabinet thereby accepting that large cabinets use more (absolute) energy than small cabinets.

The size of the cabinet is often related to the net volume of the cabinet, the purpose of the cabinet being to store a quantity of goods and the quantity of goods in the cabinet is limited by the net volume of the cabinet.

The size of the cabinet could also be related to other measures, e.g. the cabinet's:

  • gross volume
  • shelf area
  • the number of sample packages in the temperature test in EN 441-5
  • the maximum number of sample packages (in the net volume)
  • display-area (Total Display Area, TDA) for refrigeration display cabinets • etc.

However, the above seldom occurs.
