In Vapor-compression refrigeration, a refrigerant is compressed releasing heat (typically outside a building) and then decompressed in another location, absorbing heat.
A residential air conditioner works on this principle with a compressor outside the home and a blower over the decompression coils to circulate cold air.
Would it be feasible to compress ahead of cooling demand, storing the compressed refrigerant in a high pressure container for use at a later time of the day, thus shifting the power consumption to times of the day where there is less electrical demand?
By feasibility, I'm thinking of questions like:
- How much storage volume would one need for a typical household usage over an afternoon of running air conditioning given a container type that would be available cheaply, ex: propane canisters?
- What would be the sources of efficiency loss added by something like this?
