Definitions

  • a current ultrasonic absorption refrigeration model shows that at 100 , in addition to water being vaporized, some heat is generated. This amount of heat has been advantageous to avoid crystallization of the concentrated solution upon entering the low pressure at 98 , but at 130 degrees Fahrenheit, the temperature is relatively cool compared to the 200 degrees Fahrenheit of a conventional machine. Results also show a better coefficient of performance than conventional absorption machines. Results also show that supplemental heat can be used in combination with ultrasonic humidifier devices.

Abstract

A refrigeration process, employing conventional lithium bromide absorption refrigeration, the energy input of which is derived from conventional ultrasonic humidifier devices.

Description

    DETAILED DESCRIPTION
  • Conventionally at [0001] 98, a concentrated lithium bromide and water solution is sprayed and used to absorb water vapor thereby lowering the pressure and temperature of the refrigerant water at 96 and 97.
  • At [0002] 99, after absorbing refrigerant water vapor, the solution's ability to absorb additional water vapor is reduced and is therefore pumped to 100.
  • At [0003] 100 water is vaporized from the solution using conventional ultrasonic humidifier devices(existing absorption machines use heat to boil water out of the solution). Continued vaporizing of water causes water vapor pressure and temperature to increase so that heat is rejected and the water vapor is condensed to liquid water at 101.
  • At [0004] 102 liquid water flows from a higher pressure to a lower pressure at 96.
  • At [0005] 100, the lithium bromide and water solution, after having some of it's water removed, is now concentrated, having an increased ability to absorb water, is pumped and sprayed back to 98 continuing a cycle.
    •
  • By way of explanation, a current ultrasonic absorption refrigeration model shows that at [0006] 100, in addition to water being vaporized, some heat is generated. This amount of heat has been advantageous to avoid crystallization of the concentrated solution upon entering the low pressure at 98, but at 130 degrees Fahrenheit, the temperature is relatively cool compared to the 200 degrees Fahrenheit of a conventional machine. Results also show a better coefficient of performance than conventional absorption machines. Results also show that supplemental heat can be used in combination with ultrasonic humidifier devices.
