Abstract:
1. A heat exchanger comprising two single closed loops connected in a cascade arrangement consisting of: at least one first loop adapted to trap energy from a source, said first loop contains a first refrigerant adapted to collect said energy from said source; at least one second loop containing a second refrigerant, said second refrigerant adapted to interact with said first refrigerant and to transfer to a user a maximum quantity of said energy trapped by said first loop in the most efficient manner, wherein the transfer of said trapped energy takes place in a transfer unit, wherein said transfer unit is placed in said second loop, wherein said transfer unit comprises an outer cylinder adapted to contain said first refrigerant, said outer cylinder is provided with an inlet and an outlet adapted to circulate said first refrigerant, and an inner coil placed within said outer cylinder, said inner coil is adapted to contain said second refrigerant, said inner coil is provided with an inlet and outlet adapted to facilitate circulation of said second refrigerant, wherein said transfer is facilitated by interaction between said first refrigerant contained in said outer cylinder and said second refrigerant contained in said inner coil completely submerged in said first refrigerant, wherein said first refrigerant is separated from said second refrigerant by a single layer wall of said inner coil, and wherein said first refrigerant and said second refrigerant are combined in a predetermined manner to provide optimal performance efficiency and optimal compression ratio for both loops.
