COMPRESSION/ABSORPTION CYCLES FOR LARGE HEAT PUMPS. SYSTEM SIMULATIONS.

Author(s) : AHLBY L.

Type of article: Periodical article

Summary

DESCRIBES THE SIMULATION OF 3 DIFFERENT COMPRESSION/ABSORPTION CYCLES, USING A MIXTURE OF AMMONIA AND WATER. CONSIDERS THE MIXTURES WATER-LITHIUM BROMIDE, METHANOL-LITHIUM BROMIDE AND AMMONIA-WATER. THE LAST MIXTURE GAVE BETTER PERFORMANCE AND WAS CHOSEN FOR FURTHER STUDY. THE CYCLES WERE SELECTED TO IMPROVE THE PERFORMANCE IN 3 SITUATIONS TYPICAL FOR HEAT PUMP APPLICATIONS: 1) WITH LARGE HEAT SINK AND HEAT SOURCE TEMPERATURE GRADIENTS WHICH ARE OF THE SAME MAGNITUDE ; 2) WITH A LARGE HEAT SOURCE TEMPERATURE GRADIENT IN COMPARISON WITH THE HEAT SINK GRADIENT ; AND 3) WHEN A LARGE TEMPERATURE LIFT IS REQUIRED.
