Problems solved by technology

[0004] However, since the fins are arranged horizontally, there is a problem that condensed water or rainwater tends to accumulate between the fins
For example, during heating operation, since the liquid coolant is evaporated on the inner surface of the outer tube, condensed water is generated between the fins when the outer tube is cooled, and the condensed water accumulates between the fins, or freezes into frost or ice , thus causing the air supply of the fan to be unable to produce high-efficiency heat exchange
In addition, the fins or the outer tube are also easily corroded, which deteriorates the durability

Abstract

A gas-cooled absorption air-conditioner is characterized in that a condenser 30 and a double-layer tube part 40 are vertically arranged on a fin 31 and a fin 41; in an evaporating and absorbing chamber 44 arranged between an outer tube 43 and a parallel tube 81, a first injection pipe 71 paralleling the length direction is arranged along the outside of the parallel tube 81; two second injection pipes 72 paralleling the length direction are arranged so as to prevent the condensate or rain form accumulating between fins.

Description

technical field [0001] The invention relates to an air-cooled absorption air conditioner in which an evaporator and an absorber are integrally formed on double-layer pipes. technical background [0002] The prior art of such an air-cooled absorption air conditioner is, for example, the air-cooled absorption air conditioner disclosed in JP-A-6-217-43. According to this prior art, the first cold and hot water heat exchanger is installed in a part of the cold and hot water circulation pipeline of the coolant of the indoor air conditioner, and has an outer tube surrounding it at a certain interval on its outer periphery, and has a cooling system for cooling the liquid. A first injection mechanism for spraying liquid coolant or high-concentration solution on the outer surface of the first cold and warm water heat exchanger; and a second injection mechanism for spraying liquid coolant or high-concentration solution on the inner surface of the outer tube. During the cooling operat...
