Refrigeration cycle intercooler with dual coil evaporatoris a component in a refrigeration cycle where the refrigeration cycle comprises: a thermal expansion valve, an inner coil evaporator, an outer coil evaporator, a condenser, and a compressor. The refrigeration cycle operates by continuously cycling a refrigerant through a closed loop where liquid refrigerant passes through the thermal expansion valveand then simultaneously passes through the inner coil evaporatorand the outer coil evaporatorwhere the refrigerant changes from liquid to gas in the inner coil evaporatorand the outer coil evaporator, thereby providing a cooling effect at the inner coil evaporatorand the outer coil evaporator. Then the gaseous refrigerant passes through a compressorwhich increases the pressure of the gaseous refrigerant and forces it through the condenserwhere the refrigerant changes from a gas to a liquid, thereby providing a heating effect at the condenser. Then the liquid refrigerant is forced into the thermal expansion valvein order to start the whole cycle over again. The net result of the refrigeration cycle is cooling at the inner and outer coil evaporators,and heating at the condenser. During operation, fresh air or outside aircontinuously passes by the inner and outer coil evaporators,to continuously cool and dry the fresh air or outside airpassing through the inner and outer coil evaporators,. During operation, fresh air or outside aircontinuously passes through the condenserto continuously heat the fresh air or outside airpassing through the condenser. A large degree of thermodynamic efficiency is gained from the phase changes of the refrigerant in a refrigeration cycle that is considerably more than that of a standard intercooler which does not use a refrigeration cycle for its cooling.
