Patent ID: 8297066

Claim:
A refrigeration unit having a control and management assembly, comprising: a refrigeration assembly; at least one power input comprising a power line for supplying electrical power to said refrigeration assembly; at least one compressor of said refrigeration assembly whereby a presence of electrical power supply allowing an activation of said compressor to remove heat in a compartment which is formed inside said refrigeration unit and which is adapted to accommodate products to be kept at a predefined temperature; at least one control switch arranged on said power line for controlling power supply to said refrigeration assembly; at least one signal input for sending data to said control switch for driving said control switch for determining supply of electrical power to said refrigeration assembly; a sensor for detecting a presence of at least one person near said refrigeration unit and for supplying said data to said signal input whereby a detection of the presence of the at least one person causes a sending of a driving signal which is adapted to open said control switch and cause lack of power supply to said refrigeration assembly, and a detection of an absence of the at least one person causes a sending of a driving signal which is adapted to close said control switch and provide power supply to said refrigeration assembly; and a heat accumulator which is arranged inside said compartment and which contains a heat accumulation substance for releasing heat during operation of said compressor and for absorbing heat when said compressor is switched off.
