Abstract
The absorption refrigeration ammonia-lithium nitrate offers great advantages compared with the mechanical compression refrigeration with ammonia as well as with the absorption ammonia-water refrigeration. With heat temperatures of 1000 to 1400 Celsius degrees, for instance low pressure steam the generation of cold at low temperatures (-100 to -200 Celsius degrees) is possible. The system has less components and is much less expensive than the ammonia-water equipment with a price very similar to the ammonia mechanical compression equipment. The equipment consists of five main heat exchangers and a solution pump, resulting in a high reliability of its operation, requiring a minimum maintenance. The operation cost depends directly of the cost of the energy source. In case of using residual heat the operation cost is only the maintenance cost. Nowadays the cost of the electric energy is below the production cost, which can be a short term situation. In time terms of the comparable useful life time of an absorption refrigeration system (in excess of 20 years), it is reasonable to think that the operation costs will be less than the operation costs of an equipment with mechanical compression. To this day it is available a demonstration unit to exhibit the system

[Espanol] La refrigeracion por absorcion amoniaco/nitrato de litio ofrece grandes ventajas comparada tanto con la refrigeracion por compresion mecanica con amoniaco como con la refrigeracion por absorcion amoniaco/agua. Este sistema es mas eficiente y sencillo que el sistema de amoniaco/agua. Con calor de temperatura (100 a 140 grados centigrados por ejemplo vapor de baja presion, se permite la generacion de frio a temperaturas bajas (-10 a -20 grados centigrados). El sistema tiene menos componentes y es mucho mas barato que equipo de amoniaco/agua con un precio muy similar a sistemas por compresion mecanica de amoniaco. El sistema consiste en cinco intercambiadores de calor principales y una bomba para solucion, por tanto es de alta confiabilidad en su operacion, requiriendo un minimo de mantenimiento. El costo de operacion depende directamente del costo de la fuente de calor. En el caso de usar calor residual el costo de operacion solamente es el del mantenimiento. Actualmente el precio de la energia electrica se encuentra por debajo del costo de produccion lo cual solamente puede ser una situacion de corto plazo. En plazos de tiempo comparable con la vida util de un sistema de refrigeracion por absorcion (en exceso de 20 anos) es razonable suponer que los costos de operacion seran menor de los costos de operacion de un equipo por compresion mecanica. Actualmente se cuenta con una unidad de demostracion para mostrar el sistema en plantas industriales con varias fuentes de calor.}
