A Solar-Powered Heat Pump Utilizing Pivoting-Tip Rotating Equipment. Phase I

摘要

Development of the Battelle heat-pump concept for the solar heating and cooling of buildings is described. This concept utilizes pivoting-tip rotary-vane equipment. A computer simulation of the Rankine-cycle powered vapor compressor (RC-VC) heat-pump was prepared and used to: (1) analytically determine the feasibility of the Battelle solar heat-pump concept with a single working fluid, a common condenser, and rotary-vane components; and (2) provide the fluid properties, flow rates, displacements, and shaft speed required for conducting the preliminary design of the rotary-vane compressor and expander and the pivoting-tip gas bearings.
