Abstract:
A method for providing reduced energy consumption of a cooling unit for cooling at least a first space, the cooling unit having at least a compressor, for compressing a working fluid, a condenser and an evaporator, the method comprising:transferring at least first heat from said working fluid to a second fluid; placing said second fluid in thermal communication with a first change-of-phase heat storage material having a first temperature whereby at least some of said first change-of-phase material changes from a first phase to a second phase and absorbs latent heat, and wherein said first phase is substantially solid and said second phase is substantially liquid; transferring heat from said change-of-phase material to the ambient air whereby at least some of said change-of-phase material changes phase from said second phase to said first phase and releases latent heat.
