User Inputs to the Freezer Model

In the simple inputs level, users can specify the number of freezers in their house, from zero to two units. Each freezer specified has default characteristics (appliance type, size and year) assigned depending on whether it is the first or second freezer in the house (Table 17). In the detailed inputs level, users can alter these default characteristics.

Table 16. Shipment Weighted Energy Factors for Freezers

Notes on Freezer Energy Factors:

1. Energy Factor has units of (cubic feet•day/kWh), where cubic feet is adjusted volume.

2. Source: (AHAM 1996) (AHAM 2003) - AHAM changed the reporting of freezer efficiencies after 1996. Annual data is available for the “General” category. Data for the other freezer types for years subsequent to 1996 was derived from the “General” freezer efficiency by scaling the efficiency for a particular type of freezer proportional to the annual change in efficiencies in the “General” freezer category.

3. Data has been held at 2003 levels for subsequent years.
