HEAT RECOVERY IN AMMONIA REFRIGERATION PLANTS BY UTILIZATION OF EXCESS HEAT OF SUPERHEATING.

[In German. / En allemand.]

Author(s) : LAACKMANN H. P., KAUFMANN K.

Type of article: Article

Summary

IN NH3 REFRIGERATION SYSTEMS THE MECHANICAL ACTION OF THE COMPRESSOR RAISES THE TEMPERATURE OF THE NH3 TO ABOUT 343-373 K (70-100 DEG C), WELL ABOVE THE CONDENSATION TEMPERATURE OF 298 K (25 DEG C). THE EXCESS HEAT FOR SUPERHEATING THEN HAS TO BE REMOVED IN THE CONDENSER. POSSIBILITIES OF UTILIZING THIS EXCESS HEAT BY MEANS OF A HEAT RECOVERY UNIT ARE DISCUSSED ON THE BASIS OF THE LITERATURE AND INITIAL EXPERIMENTAL RESULTS AT THE ORANIENBURG DAIRY RESEARCH INSTITUTE. DIAGRAMS SHOW VARIOUS CONFIGURATIONS FOR WATER HEATING. SPACE HEATING APPLICATIONS ARE ALSO MENTIONED. (DAIRY SCI. ABSTR., GB., 44, N.11, 1982/11, 802, 7344.
