Abstract
A hybrid absorber is disclosed for a closed absorption cycle apparatus. The hybrid absorber is comprised of a non-adiabatic section plus an adiabatic spray section in that order, with absorbent solution and vapor supplied sequentially to them. The spray section preferably also includes a non-adiabatic spray cooler. Coolant is supplied to the non-adiabatic absorber and the cooler either in parallel or in series, countercurrently to the absorbent.
Claims20
A hybrid absorber for a closed cycle absorption apparatus, comprised of:
- a. a non-adiabatic absorption section;
- b. an adiabatic spray absorption section that receives vapor and liquid from said non-adiabatic section;
- and
- c. a recirculating liquid spray loop for said adiabatic section, comprised of a spray pump that is piped directly to said adiabatic section, and a spray cooler that is piped directly to said spray pump.
A hybrid absorber for a closed cycle absorption apparatus, comprised of:
- a. a non-adiabatic absorption section;
- b. an adiabatic spray absorption section that receives vapor and liquid from said non-adiabatic section;
- c. a recirculating liquid spray loop for said adiabatic section, comprised of a spray pump and a cooler;
- and
- d. a spray receiver for said solution that has separate suction pipes for the spray pump and the solution pump, plus a partition between the two suctions.
A closed absorption cycle apparatus comprised of:
- a. an absorber comprised of a non-adiabatic section followed by an adiabatic spray section, the latter including a spray pump and a spray cooler, and wherein said adiabatic spray section receives both vapor and liquid from said non-adiabatic section;
- b. a desorber;
- and
- c. a solution pump that circulates absorbent from said absorber to said desorber.
An absorption process for producing at least one of refrigeration, heat pumping, and power from a heat source, comprising:
- a. desorbing vapor from an absorbent liquid with said heat source;
- b. absorbing the vapor at lower pressure into the desorbed liquid in a multi-step process comprised of:
- i. partially absorbing the vapor in a non-adiabatic absorber;
- ii. routing the residual vapor and liquid to an adiabatic spray absorber;
- iii. absorbing the residual vapor in an adiabatic spray absorber;
- and
- iv. recirculating and cooling the spray liquid.
