摘要： Fans are disposed on an upper wall face out of the upper wall face, a lower wall face and side wall faces which constitute an outside frame of a machine body. An air-cooled absorber is disposed on two adjacent wall faces. An air-cooled condenser is disposed on one wall face of the remaining side wall faces. A main apparatus comprising such as an evaporator, a high-temperature regenerator, a low-temperature regenerator, a solution heat exchanger and pipes for connecting operatively the apparatuses together is disposed on an inner portion of the machine body so as to be surrounded by the air-cooled absorber and the air-cooled condenser. Thus, a noise generated from the refrigerating machine is reduced.

摘要： Refrigerant vapor generated in a high temperature regenerator is condensed in a condenser, and the refrigerant vapor is changed to refrigerant liquid. Then it is conducted to a first evaporator. The refrigerant vapor evaporated in the first evaporator is absorbed in a solution in a first absorber. The refrigerant liquid conducted from the condenser without vaporizing in the first evaporator is introduced to a second evaporator, and it evaporates in the second evaporator. The refrigerant vapor in the second evaporator is absorbed in the solution in a second absorber. The first and the second evaporator and the first and the second absorber are made of a unitary chamber. The first evaporator is juxtaposed to the second absorber with a heat transfer member. The concentration of the refrigerant in the second evaporator is controlled by a refrigerant liquid controller that controls a flow rate of the refrigerant liquid flowing from the first evaporator at the predetermined value.

An inner casing (2) defines therein a combustion chamber (11B) on the blow out port side of a burner for blowing out combustion gas. The solution is filled in liquid chambers defined in an outer casing (1) above and below the combustion chamber. A coolant vapor outlet passage (8) is defined in the upper part of the outer casing, and gas exhaust passages (13, 14) are defined in the combustion chamber on a side remote from the burner. A plurality of solution tubes 3 communicated with the liquid chambers above and below the combustion chamber are extended through he combustion chamber. The plurality of solution tubes are plane tubes having fins (16) at their side surfaces. The fins are provided only on the upstream side. With these fins, the heat-exchange between the solution filled in the plane tubes and the combustion gas can be promoted so as to promote the flow of the solution.
