Abstract
A refrigeration unit and a respective control and management assembly, comprising a refrigeration assembly and at least one power input for its electrical power supply. The refrigeration unit comprising at least one signal input and at least one control switch, which is arranged along a power line which corresponds to the power input. The control switch controlling the power line and the data that arrive from the respective signal input being suitable for driving the control switch for consequently determining the presence/absence of electrical power supply for said refrigeration assembly.
Claims13
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.

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 a presence of electrical power suppler 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 mains switch arranged substantially downstream of an electrical power supply mains for supplying said data to said signal input whereby a closure of said mains switch sending a driving signal which is adapted to open said control switch and cause lack of power supply to said refrigeration assembly, and an opening of said mains switch sending 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 meat during operation of, said compressor and for absorbing heat when said compressor is switched off.

- at least one power input comprising a power line for supplying electrical power to said refrigeration assembly;
- 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;
- and
- a mains switch driven by a detection sensor for supplying said data to said signal input as a driving signal constituted by a presence or absence of voltage across a signal line, whereby the presence of voltage on the signal line causing an opening of said control switch and causing lack of power supply to said refrigeration assembly, and a lack of voltage causing a closure of said control switch and providing power supply to said refrigeration assembly.
