    摘要: The intermittent absorption refrigeration system includes a primary circuit having a generator/absorber, a dephlegmator, a condenser, an evaporator, and solar collectors to provide heat to the generator. The system also includes an ejector-based secondary circuit having a generator/absorber, an ejector, a condenser, a refrigerant storage unit, and solar collectors. Both circuits are aqua-ammonia systems, using ammonia as the refrigerant and water as the absorber liquid. The ejector permits evaporation during the daytime and storage of liquid ammonia refrigerant that is used for cooling in the heat exchanger of the primary circuit condenser and in the primary circuit absorber, thus permitting the primary circuit evaporator to operate at lower temperatures for low temperature freezing applications in the daytime, even at high ambient temperature.

    摘要: Apparatus and process are disclosed for a new absorption heat pump cycle which achieves a COP of approximately one and a half times that achievable in a single-effect cycle, at generator temperatures substantially less than the minimum required for double-effect operation. This is done by providing two internally heated generators (108 and 109 of FIG. 1) in addition to the externally-heated generator (110); plus at least two separate and distinct absorbent solution circulating loops (112-114 and 120-122); and a transfer of vapor from one of the generators (108) to one of the absorbers (116).

    摘要: A double-effect absorption refrigeration system is provided with a novel, generally concentric and vertically-elongated high-pressure condenser chamber, low-pressure desorber, and low pressure condenser combination. Such combination further includes novel annular liquid collection cups located at the combination lower extremes to receive high-pressure liquid refrigerant, low pressure concentrated refrigerent solution, and low-pressure liquid refrigerent. Flow restrictor devices are incorporated in distribution lines connecting the collection cups to a system evaporator/absorber assembly to further enhance temperature, concentration, and pressure conditions imparted to the liquids flowed for absorption purposes.

    摘要: Multi-effect regenerative absorption cycles which provide a high coefficient of performance (COP) at relatively high input temperatures. An absorber-coupled double-effect regenerative cycle (ADR cycle) (10) is provided having a single-effect absorption cycle (SEA cycle) (11) as a topping subcycle and a single-effect regenerative absorption cycle (1R cycle) (12) as a bottoming subcycle. The SEA cycle (11) includes a boiler (13), a condenser (21), an expansion device (28), an evaporator (31), and an absorber (40), all operatively connected together. The 1R cycle (12) includes a multistage boiler (48), a multi-stage resorber (51), a multisection regenerator (49) and also uses the condenser (21), expansion device (28) and evaporator (31) of the SEA topping subcycle (11), all operatively connected together. External heat is applied to the SEA boiler (13) for operation up to about 500 degrees F., with most of the high pressure vapor going to the condenser (21) and evaporator (31) being generated by the regenerator (49). The substantially adiabatic and isothermal functioning of the SER subcycle (12) provides a high COP. For higher input temperatures of up to 700 degrees F., another SEA cycle (111) is used as a topping subcycle, with the absorber (140) of the topping subcycle being heat coupled to the boiler (13) of an ADR cycle (10). The 1R cycle (12) itself is an improvement in that all resorber stages (50b-f) have a portion of their output pumped to boiling conduits (71a-f) through the regenerator (49), which conduits are connected to and at the same pressure as the highest pressure stage (48a) of the 1R multistage boiler (48).
