Problems solved by technology

However, in this air conditioner, it is limited to local treatment such as the absorption pipe of the bent absorber, and the overall layout of the device has not been improved, so it is not possible to achieve sufficient miniaturization for household use.

Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings. Fig. 5 is a layout view of main components of an absorption refrigerator according to an embodiment of the present invention. Here, the absorption air conditioner is assumed to be an embodiment of the absorption refrigerator. Fluorinated ethanol such as trifluoroethanol (TFE) is stored in the evaporator 1 as a refrigerant, and DMI derivatives (DMI derivatives) are stored in the absorber 2 as a solution containing an absorbent. In this case, the above-mentioned refrigerant is not limited to fluorinated alcohol, as long as it can obtain a wide non-freezing range. The solution is not limited to DMI derivatives, as long as it has a wide non-crystalline range, has a boiling point higher than TFE at normal pressure, and can absorb TFE. For example, in the case of combining water and lithium bromide, it is difficult to say that the system of this embodiment is suitable for th...

Abstract

An absorption refrigerator is minimized in the size and the weight. A sensible heat exchanger 14 and a cooling fan 19 for cooling the sensible heat exchanger are mounted front and rear opposite to each other to form a cooling unit. At one side of the fan 19, a regenerator 3 and a rectifier 6 are aligned vertically one over the other. At the other side of the fan 19, an evaporator 1 and an absorber 2 of a rectangular configuration are provided side by side. A condenser 9 is laid above the cooling unit. The cooling unit, the evaporator 1, the absorber 2, the condenser 9, the regenerator 3, the rectifier 6, and a set of pumps P1 to P4 all are installed in a main housing 20 of substantially a rectangular parallelopiped shape having a depth reduced axially of the cooling fan 19.

Description

technical field [0001] The present invention relates to absorption refrigerating machines (including refrigerating machines performing heat pump heating operation), and more particularly to absorption refrigerating machines capable of being miniaturized by improving the arrangement of constituent parts. Background technique [0002] Absorption refrigerators that operate on an absorption refrigeration cycle have been known as air conditioners. However, in recent years, attention has been paid to the advantages of high energy conversion efficiency during operation. There is increasing demand for absorption chillers, the heat pump heating operation utilizing the heat extracted from the outside air by the evaporator. [0003] For example, Japanese Patent Publication No. 6-97127 discloses such an absorption air-conditioning machine, which can operate with air conditioning, heating with heat pump operation, and heating with direct fire combustion (boiler) operation. mode of opera...
