Abstract:
A method for providing reduced energy consumption of a cooling unit for cooling at least a first space, the cooling unit having a compressor, for compressing a working fluid, a condenser and an evaporator, the method comprising:transferring at least first heat to a first change-of-phase heat storage material having a first temperature, at least during a first time period, 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-phage material to said ambient air, without transferring heat from said change-of-phase material directly to said working fluid, at least during a second time period, whereby at least some of said change-of-phase material changes phase from said second phase to said first phase and releases latent heat.
