Abstract

A temperature regulating system for at least one galley compartment for an in-flight kitchen which is intended for installing in a transport apparatus or vehicle, especially in an aircraft, includes a controllable cooling and heating element, which is designed for selectively cooling or heating a specified section of the cooling and heating element, and a heat-insulating partitioning wall, which at least partially adjoins an encompassing side edge of the cooling and heating element and encloses the specified section of the cooling and heating element. The heat-insulating partitioning wall is designed for separating an interior space of the galley compartment from an interior of a section of a fluid duct which extends in the in-flight kitchen.

First claim

The invention claimed is:

1. A temperature regulating system for at least one galley compartment for an in-flight kitchen which is intended for installing in a transport apparatus or vehicle, wherein the temperature regulating system comprises:
a controllable cooling and heating element, which is configured for selectively cooling or heating a specified section of the cooling and heating element, the cooling and heating element comprising at least a thermoelectric element or a refrigerating machine;
a heat-insulating partitioning wall, which at least partially adjoins an encompassing side edge of the cooling and heating element and encloses the specified section of the cooling and heating element;
a delivery fan configured to control a speed at which a first fluid, present in the galley compartment, is delivered via the section of the cooling and heating element; and
a controller configured to control temperature inside of the at least one galley compartment;
the galley compartment having a heat-insulating door for closing off an opening of the galley compartment, wherein a first presetting device, in communication with the controller, is on, or in a proximity of, the heat-insulating door for presetting a setpoint temperature for the interior space of the galley compartment;
wherein the heat-insulating partitioning wall is configured for separating an interior space of the galley compartment from an interior of a section of a fluid duct which extends in the in-flight kitchen; and
either of:
wherein the controller is configured to control temperature inside of the at least one galley compartment based on readings from radio frequency tags stored in the at least one galley compartment;
wherein the controllable cooling and heating element is a thermoelectric element and the controller is configured for applying a variable voltage to the thermoelectric element and changing a polarity of the voltage; or
wherein the controllable cooling and heating element is a refrigerating machine with two heat exchangers, ducts for a cooling medium and at least one valve in the ducts, wherein the controller is configured for controlling the at least one valve of the refrigerating machine so that the cooling medium is selectively ducted through one of the two heat exchangers for heat absorption or heat release.

2. The temperature regulating system according to claim 1 ,
wherein the delivery fan is on a side of the partitioning wall facing the interior space of the galley compartment.

3. The temperature regulating system according to claim 1 , further comprising:
a first heat exchanger, which is on a side of the cooling and heating element facing the section of the fluid duct; and/or
a second heat exchanger, which is on a side of the cooling and heating element facing the interior space of the galley compartment.

4. The temperature regulating system according to claim 1 , wherein the transport apparatus or vehicle comprises an aircraft.
