A carbot freezer takes heat from water at `0^(@)C` inside it and rejects it to the room at a temperature of `27^(@)C`. The latent heat of ice is `336xx10^(3)Jkg^(-1)`. If 5kg of water at `0^(@)C` is converted into ice at `0^(@)C` by the freezer, then the enrgy consummed by the freezer is close to :
