You mean make stuff up, such as words like "refridgeeration."

refrigeration is based on two properties:
the energy transferred in the state change of a fluid to a gas and back, and the energy transferred between two mediums - the interior and exterior of a vessel that is sealed.
Energy is applied to the system to transport the energy from the interior to the exterior of the vessel. Modern refrigerants use compression to convert the gas to a liquid and then change pressure to get the change in state.
It so happens that the proerties of hdroflourocarbons are particularly efficient at the temperatures and ambient conditions of a home or car.
One interesting material under investigation is wax. Wax can be made to melt and solidify with a large amount of energy transfer and very little change in volume. One could then use water as the fluid for transport and the state change of the wax to provide the energy conversion.

You can't really develop a new type of refrigeration. It will always be a thermal dynamic process require a refrigerant gas/fluid for heat transfer. However, it can be improved by making it more energy efficient and quicker in it's cooling rate.
