Multi-coil evaporator for refrigeration system

Abstract

A multi-coil evaporator device, for use in a refrigeration system, including first and second evaporator coil members located in and defining a cooling area, to be in fluid communication with air flowing through the cooling area to cool the air flowing there through. Each one of the first and second evaporator coil member is part of a respective subsystem of the refrigeration system having a respective compressor member, a respective condenser member, and a respective pressure reducer member with a respective cooling refrigerant flowing therein. Each respective subsystem is operatively independent from one another.

1 . A multi-coil evaporator device for use in a refrigeration system, the evaporator device comprising:
 first and second evaporator coil members located in and defining a cooling area, for being in fluid communication with air flowing through the cooling area to cool the air flowing there through; and   wherein each one of the first and second evaporator coil member being part of a respective subsystem of the refrigeration system having a respective compressor member, a respective condenser member, and a respective pressure reducer member with a respective cooling refrigerant flowing therein, each said respective subsystem being operatively independent from one another.   
     
     
         2 . The device of  claim 1 , further comprising a fin arrangement connecting to the first and second evaporator coil members to increase cooling of the air flowing through the cooling area. 
     
     
         3 . The device of  claim 2 , wherein the fin arrangement includes a plurality of fins, each said plurality of fins being in contact with the first and second evaporator coil members. 
     
     
         4 . The device of  claim 1 , further comprising a fan subsystem for blowing the air through the cooling area. 
     
     
         5 . The device of  claim 2 , further comprising a fan subsystem for blowing the air through the cooling area. 
     
     
         6 . The device of  claim 3 , further comprising a fan subsystem for blowing the air through the cooling area. 
     
     
         7 . A refrigeration system comprising:
 a multi-coil evaporator device having first and second evaporator coil members located in and defining a cooling area, for being in fluid communication with air flowing through the cooling area to cool the air flowing there through;   a fan subsystem for blowing the air through the cooling area; and   first and second subsystems operatively connecting to the first and second evaporator coil members, respectively, each one of the first and second subsystems having a respective compressor member, a respective condenser member, and a respective pressure reducer member with a respective cooling refrigerant flowing therein, the first and second subsystems being operatively independent from one another.   
     
     
         8 . The system of  claim 7 , further comprising a fin arrangement connecting to the first and second evaporator coil members to increase cooling of the air flowing through the cooling area. 
     
     
         9 . The system of  claim 8 , wherein the fin arrangement includes a plurality of fins, each said plurality of fins being in contact with the first and second evaporator coil members. 
     
     
         10 . The system of  claim 7 , further comprising a fan subsystem for blowing the air through the cooling area.
