A dual-function absorption heat pump cycle for space conditioning and water purification.

Number: pap. n. 1521

Author(s) : BOMAN D. B., GARIMELLA S.

Summary

A dual-function absorption heat pump cycle is developed for graywater purification and space conditioning. This cycle extracts vapor directly from an impure feed in the evaporator and collects condensate in the condenser while running membrane distillation in parallel with the desorber to allow additional water production. Thermodynamic modeling of this cycle is conducted by solving
mass, species, and energy balances for each of the cycle components. Lithium bromide is used as the absorbent. Baseline performance of the cycle is determined at a set of operating conditions associated with a single-family home in the U.S. Parametric studies are conducted to determine water flows and performance over a range of water loads. The energy ratio of the cycle, which
measures the total useful output as a function of power input, peaks above 1.5 for cooling mode and 1.6 for heating mode.
