Is this any help? In Cornell, they use the greenhouse for warmth, not coolth.
But part of it talks about moving canes around in pots and then getting a quickie crop from them.

"Floricane raspberry production
The concept of floricane production is to grow plants in pots, allow plants to fulfill their chilling requirement, then bring them into a greenhouse where the plants experience “spring.” "

"If a cooler is available, canes can be held inside for several months, then moved into the greenhouse for late spring production"
However, it sounds like primocane-fruiting raspberry varieties (Rubus idaeus L.) have easier chilling requirements.
