R&D of Absorption Heat Pump System Using New Working Fluid To Utilize Treated Sewage Water

1st Report: Performance of Absorption Machine

Abstract

The absorption heat pump system has been developed to utilized treated sewage water from the view point of environmental protection and energy conservation.
The development has two step. Conventional LiBr solution is used at the first step, the new working fluid with higher solubility and lower viscosity is used to imprve the efficiency of absorption heat pump at the second step.
The first report says the search for the new working fluid and the performance of absorption heat pump concerned with the second step. LiBr, LiI, LiCl, LiNO₃, solution was selected as the new working fluid. The absorption heat pump using the new working fluid was tested and better results were obtained by comparision with LiBr solution.
