Liquid dispensing device and absorption type cold and hot water machine equipped with liquid dispensing device

Abstract

The invention relates to a liquid dispensing device for an absorption type cold and hot water machine. The device is equipped with more than one stage chutes. The chutes are arranged above a heat conduction pipe. In the liquid dispensing device, the overlapped region between the chutes or the overlapped region between the chutes and the heat conduction pipe is defined as the target region. The specific region in the target region is defined as the effective region. The specific region is a region with the average diameter of the dispensing opening reduced into a half thereof compared with the target region. Therefore, the dispensing opening positioned inside the target region is located between the target area at the outlines of each dispensing opening area at least obtained by the effective region 50 %.

Description

technical field [0001] The present invention relates to an absorption chiller, and more specifically, to a liquid distributing device for distributing refrigerant liquid or absorbing liquid to heat transfer tubes provided in evaporators, absorbers, and the like. Background technique [0002] The absorption chiller is a system that uses the vapor absorption characteristics of lithium bromide (LiBr) aqueous solution to realize cooling and heating. In order to ensure its performance, the inside of the system is kept in a high vacuum state. In addition, the absorption-type hot and cold water machine is different from the cold and hot water machine that uses electricity as an energy source, and uses gas such as LPG and LNG as a heat source, thereby solving the problem of excessive power consumption in summer, and It is fully utilized for various advantages such as a heat combination system that utilizes waste heat. [0003] figure 1 It is a conceptual diagram showing a general ...

AI Technical Summary

Problems solved by technology

However, in the distribution devices 35, 36 of the conventional absorption chiller 1, the positions and sizes of the chute holes are not designed so that the refrigerant liquid or the absorption liquid can be evenly distributed to the heat transfer tubes at a predetermined flow rate. Problems that can cause reduced heat transfer performance

[0012] In addition, in the distribution devices 35 and 36 of the conventional absorption-type hot and cold water machine 1, the refrigerant liquid or the absorbing liquid flowing into the chute overflows from the chute or splashes to the outside, thereby reducing the heat transfer performance.
