Development of a chemically assisted mechanical refrigeration cycle. Final report
In its most basic version, the chemically assisted mechanical, CAM, refrigeration cycle operates as follows: A pressurized solution of refrigerant gas dissolved in a liquid solvent is introduced into an evaporator-effervescer, EE, where, at reduced pressure, the refrigerant effervesces, or boils, out of the solvent liquid. In so doing, it absorbs both the latent heat of vaporization and the heat of dilution (heat of dissolution, heat of disassociation, heat of mixing) required to disassociate it from the solvent. Vaporized refrigerant and pure solvent may then be separated (using an eliminator at the top of the EE if necessary) and the refrigerant is drawn to a compressor while the solvent is circulated to the condenser-mixer, CM. If appropriate, the refrigerant can be foamed with the solvent, and both can be circulated to the compressor together, eliminating the solvent pump. In fact, to achieve maximum cycle efficiency, the refrigerant gas should be compressed in the presence of the cool solvent, to achieve more nearly isothermal than isentropic compression. The compressed refrigerant gas is next mixed with and dissolved into the returned solvent in the CM. Here is given up the latent heat of condensation determined by the amount of gas entering the liquid phase and also the corresponding heat of mixing.
