Thermoelectric Device Based Mobile Freezer/Heater

Abstract

A heating and cooling system is connected to a mobile food carrying cart comprising at least one shelf and one or more thermoelectric devices.

1 . A heating and cooling system connected to a mobile food carrying cart, the system comprising:
 at least one shelf; and   a plurality of thermoelectric devices connected to said at least one shelf, wherein each of said plurality of thermoelectric devices is in thermal communication with said at least one shelf, and wherein each of said plurality of thermoelectric devices heat, cool, and provides temperature control storage at a preselected temperature.   
   
   
       2 . The system of  claim 1 , wherein each of said plurality of thermoelectric devices has a connection socket. 
   
   
       3 . The system of  claim 2 , further comprising a control box selectively connectable to said connection socket. 
   
   
       4 . The system of  claim 3 , further comprising a power supply connected to said control box, wherein said control box adjustably controls energy provided to said plurality of thermoelectric devices from said power supply. 
   
   
       5 . The system of  claim 4 , wherein said power supply is selected from the group consisting of a fuel cell, a photovoltaic, a fuel or heat driven generator, an internal combustion engine, a solar cell, a power grid, a battery bank, and any combination thereof. 
   
   
       6 . The system of  claim 1 , wherein said plurality of thermoelectric devices are adapted to simultaneously store, heat, and cool said at least one shelf at different temperatures. 
   
   
       7 . The system of  claim 6 , wherein each of said plurality of thermoelectric devices is independently controllable by said control box. 
   
   
       8 . The system of  claim 1 , further comprising a vapor compression cycle connected to the mobile food carrying cart. 
   
   
       9 . A mobile food carrying cart for transporting food products to different locations at a desired temperature comprising:
 a support structure;   at least one shelf removably connected to said support structure; and   a plurality of thermoelectric devices connected to said at least one shelf, wherein each of said plurality of thermoelectric devices is in thermal communication with said at least one shelf, and wherein each of said plurality of thermoelectric devices heat, cool, and provides temperature control storage at a preselected temperature.   
   
   
       10 . The cart of  claim 9 , wherein each of said plurality of thermoelectric devices has a socket connected thereto. 
   
   
       11 . The cart of  claim 10 , further comprising a control box selectively connectable to said socket. 
   
   
       12 . The cart of  claim 11 , further comprising a power supply connected to said control box, wherein said control box adjustably controls energy provided to said plurality of thermoelectric devices from said power supply. 
   
   
       13 . The cart of  claim 12 , wherein said power supply is selected from the group consisting of a fuel cell, a photovoltaic, a fuel or heat driven generator, an internal combustion, a solar cell, a power grid, a battery bank, and any combination thereof. 
   
   
       14 . The cart of  claim 9 , wherein said plurality of thermoelectric devices are adapted to simultaneously store, heat, and cool said at least one shelf at different temperatures. 
   
   
       15 . The cart of  claim 14 , wherein each of said plurality of thermoelectric devices is independently controllable by said control box. 
   
   
       16 . The cart of  claim 9 , further comprising a vapor compression cycle connected to said support structure. 
   
   
       17 . The cart of  claim 9 , wherein said at least one shelf is a plurality of shelves. 
   
   
       18 . A method of transporting food products comprising:
 storing the food products in a mobile cart having a plurality of thermoelectric devices in thermal communication with the food products;   controlling energy provided to said plurality of thermoelectric devices connected to at least one shelf of said mobile cart; and   transporting said mobile cart to a desired location for delivery of the food products.   
   
   
       19 . The method of  claim 18 , further comprising removably connecting a power supply to a quick connect socket, wherein said quick connect socket is connected to said plurality of thermoelectric devices.
