Abstract
An absorbent pair refrigeration system comprising a source of liquid refrigerant; an evaporator for transforming the liquid refrigerant into vapor refrigerant at a lower temperature than the liquid refrigerant to thereby provide a desired cooling effect; a volume of absorbent in communication with the evaporator, wherein the vapor refrigerant is absorbed onto the absorbent; an electromagnetic wave generator for desorbing the vapor refrigerant from the absorbent without appreciably heating the absorbent; and a condenser in communication with the absorbent for condensing the vapor refrigerant which has been desorbed from the absorbent.
Claims7
An absorbent pair refrigeration system comprising:
- a source of liquid refrigerant;
- an evaporator for transforming the liquid refrigerant into vapor refrigerant at a lower temperature than the liquid refrigerant to thereby provide a cooling effect;
- a volume of chemical absorbent in communication with the evaporator;
- wherein the vapor refrigerant is absorbed onto the chemical absorbent to form a refrigerant/absorbent compound;
- electromagnetic wave generator means for desorbing the refrigerant from the refrigerant/absorbent comound;
- and
- a condenser in communication with the chemical absorbent for condensing the vapor refrigerant which has been desorbed from the refrigerant/absorbent compound;
- wherein the refrigerant/absorbent compound is not heated by the electromagnetic wave generator means to a degree sufficient to thermally desorb the refrigerant from the refrigerant/absorbent compound.
A refrigeration system comprising:
- a refrigerant;
- means for evaporating the refrigerant to provide a cooling effect;
- a sorbent in communication with the evaporating means;
- wherein the sorbent and the refrigerant from the evaporating means combine in a sorption reaction;
- electromagnetic wave generator means for desorbing the refrigerant from the sorbent;
- wherein electromagnetic energy from the electromagnetic wave generator means is converted into work which acts to separate the refrigerant from the sorbent in a primarily isothermal reaction;
- and
- means in communication with the sorbent for condensing the refrigerant which has been desorbed from the sorbent.
A method for producing a cooling effect comprising the steps of:
- providing a refrigerant;
- providing a sorbent;
- combining the refrigerant with the sorbent to effect a sorption reaction;
- applying electromagnetic energy to the refrigerant/sorbent combination to desorb the refrigerant from the sorbent;
- wherein the electromagnetic energy is converted into work which acts to separate the refrigerant from the sorbent in a primarily isothermal reaction;
- evaporating the refrigerant that has been desorbed from the sorbent to achieve the cooling effect.
