Air conditioning system utilizing thermal capacity from expansion of compressed fluid
First Claim
1. A vehicle air conditioning system, comprising:
- a first vapor compression refrigeration loop comprising;
a first refrigerant compressor; and
a first evaporator; and
a tank configured to hold a compressed fluid, the compressed fluid configured to drive a vehicle power source;
a tank outlet configured to allow fluid from the tank to flow to and drive the vehicle power source, wherein the tank outlet is configured to reduce the temperature of the fluid as a result of expansion of the fluid upon exiting the tank; and
a heat exchanger coupled to the first refrigeration loop, the heat exchanger comprising;
a first refrigerant inlet coupled to the first refrigeration loop;
a fluid inlet coupled to the tank outlet; and
a fluid outlet coupled to the vehicle power source;
wherein the heat exchanger is configured to transfer heat from refrigerant in the refrigeration loop to the fluid from the tank; and
wherein the heat exchanger is further configured to provide the heated fluid to the vehicle power source without returning the heated fluid to the tank.

Abstract
A vehicle air conditioning system is provided. The vehicle air conditioning system includes a first vapor compression refrigeration loop. The first vapor compression refrigeration loop includes a first refrigerant compressor and a first evaporator. The vehicle air conditioning system further includes a tank for holding a compressed fluid, an outlet configured to carry expanded fluid from the tank, and a heat exchanger thermally coupled to the first vapor compression refrigeration loop and to the outlet. The heat exchanger is configured to transfer heat from refrigerant carried by the first vapor compression refrigeration loop to fluid carried by the outlet, where the temperature of the fluid carried by the outlet has been reduced as a result of expansion of the fluid upon exiting the tank.
