Abstract
The present invention describes a vapour compression apparatus wherein an intermediary located heat battery is capable of releasing charge (i.e. discharging) and/or charging and thereby controlling the temperature of a heat source or heat sink temperature in a vapour compression cycle. More particularly, the present invention describes vapour compression apparatus wherein an intermediary located heat battery comprising Phase change material (PCM) is capable of releasing charge (i.e. discharging) energy and/or charging and thereby controlling the temperature of a heat source and/or heat sink temperature in a vapour compression cycle in a range of refrigeration and/or heating systems including: air conditioning in both domestic and industrial uses; transportation of food/materials in vehicles, trains, air, etc. The present invention also relates to a methodology for selecting phase change materials (PCMs) and/or refrigerants for a vapour compression apparatus.
