    摘要： PROBLEM TO BE SOLVED: To concentrate a dilute solution diluted by an absorber by either sunlight heat or a burning heat source and perform operation with good efficiency.SOLUTION: The sunlight heat utilized steam absorption chiller includes a regenerator 1 which uses steam generated by sunlight heat as a heat source, the absorber 6, an evaporator 5, and a condenser 4, and has a heat exchanger 10 for allowing heat exchange between a dilute solution flowing from the absorber to the regenerator and a concentrated solution flowing from the regenerator to the absorber. The chiller is provided with a means for generating steam by the burning heat source, and either the steam generated by the burning heat source or the steam generated using sunlight heat can be input as the heat source for the regenerator. The chiller is provided with a steam drain heat recovery unit 105 for allowing heat exchange between at least part of the dilute solution flowing from the absorber to the regenerator and a steam drain discharged from the regenerator to allow heat recovery from the steam drain.

    摘要： A multi-effect heat pump comprises at least three pairs of exchange units A, B; C, D; E, F, i.e. units which operate as generator, condenser, evaporator or absorber in at least two interconnected heat-pump circuits. Each pair operates in a different pressure range and the exchange units of each pressure range operate in different temperature ranges. An exchange unit (B) operating as condenser in an upper pressure range is adapted to deliver heat of condensation to a first exchange unit (C) operating as a second generator in a medium pressure range, and a second exchange unit (E) operating as absorber in a lower pressure range is adapted to deliver heat of absorption to a second exchange unit (D) operating in said medium pressure range. Means (84, 160, 166) are provided for selectively enabling and disabling alternatively the transfer of heat to said first exchange unit (C) or to said second exchange unit (D) to adapt the operation of the heat pump to varying conditions and demands.

    摘要： An absorption refrigeration system incorporating a novel solution flow control is disclosed. The solution flow control includes a sensor, preferably in the form of a float which senses the level of the solution in the absorber of the system. The signal from the level sensor is utilized to position a valve for controlling the flow of weak solution in such a manner that the solution flow increases/decreases as the level of the solution in the absorber decreases/increases. The solution control not only provides improved efficiency of the refrigeration system but also protects the system from the risk of crystallization of the solution. In one embodiment, a compact solution control is fully enclosed by an air-tight shell of the absorber and comprises a float, a rod mechanically and drivingly coupling the float with a solution valve so that the buoyancy of the float directly positions the valve. This arrangement does not need to meet the requirement of having an air tight structure and assures a long life in use.
