In a rectifying apparatus of vapor/liquid contact type, the rectifier 5 is disposed above a regenerator 4 and has two stages, a lower recovery stage and an upper condensation stage. The two stages are filled with filler elements 7a, 7b and 7c, 7d, respectively. Each filler elements 7a and 7c has a conical bottom for biasing the falling liquid towards its center and the rising refrigerant vapor towards its outer edge. The rising speed of the refrigerant vapor is made more uniform and the falling liquid has less tendency to drip down along the side wall. As the contact between the vapor and the liquid is increased, the efficiency of rectification is enhanced.

Rectifying apparatus for absorption refrigerator

An absorption refrigerating/heating apparatus in which a refrigerant vapor generated in the evaporator (1) is absorbed to produce absorption heat by the absorbent in an absorber (2). There are first tube for chilled water in the evaporator, a second tube for cooling water in the absorber, a third tube in an indoor unit (15), and a forth tube in a sensible heat exchanger. The first tube and the second tube are respectively connected to the third tube and the fourth tube in a cooling operation, while to the fourth tube and the third tube respectively in a heating operation.

Absorption refrigerating/heating apparatus

Pipings for joining pumps for delivering absorbent solution and refrigerant with an absorber and an evaporator are eliminated for minimizing the dimensions of the absorber or the evaporator, preventing leakage under pressure, and reducing heat loss and cavitation. Two pumps P2 and P3 for circulating and delivering the absorbent solution in a lower tank 21 are mounted in side-by-side relationship in a recess of a base 23 of the lower tank 21. The base 23 has a space therein for accommodating an impeller 36. The space forms a part of pump chamber communicated to a flow passage 37.
