US 6,158,237 A · Rotatable heat transfer apparatus

Abstract

Heat transfer apparatus comprises a refrigeration assembly having a low pressure region and a high pressure region. The apparatus may also include a power generation assembly connected to the refrigeration assembly between the low and high pressure regions. The refrigeration assembly and the power generation assembly are so arranged that refrigerant in the high pressure region can be passed through the power generation assembly to the low pressure region of the refrigeration assembly. Power may be generated by the power generation assembly on passage therethrough of the refrigerant. The apparatus may also include an absorption region comprising a piston and cylinder, ejector cycles in combination with absorption cycles, fibre heat exchanges, vortex tubes, and one embodiment comprises lamp or a torch.
