Absorption chiller with triple function

Abstract

The invention provides a triple-effect absorption refrigerating machine capable of suppressing energy loss. The triple-effect absorption refrigerating machine 1 comprises an absorber A for changing solution S into diluted solution Sw having lower concentration, a low temperature regenerator G1 for heating the diluted solution Sw to evaporate refrigerant and increase the concentration, a medium temperature regenerator G2 for heating the diluted solution Sw to evaporate the refrigerant at a higher temperature than that in the low temperature regenerator G1 and increase the concentration, a high temperature regenerator G3 for heating the introduced diluted solution Sw to evaporate the refrigerant at a higher temperature than that in the medium temperature regenerator G2 and increase the concentration, a medium temperature solution pump 12 for feeding the diluted solution Sw from the absorber A into the medium temperature regenerator G2, and a high temperature solution pump 13 for feeding the diluted solution Sw from the absorber A into the high temperature regenerator G3. The proper amount of diluted solution is stably supplied to the high temperature regenerator and the medium temperature regenerator without providing a resistor at the entrance of the medium temperature regenerator, thus suppressing energy loss.

Description

technical field [0001] The present invention relates to a triple effect absorption refrigerator, and more particularly to a triple effect absorption refrigerator capable of stably supplying a solution to each regenerator while suppressing energy loss. Background technique [0002] In recent years, awareness of environmental protection of the earth is increasing, but on the other hand, there is concern about the impact on the environment caused by a significant increase in energy consumption. Now that the so-called Kyoto Protocol is in force, it is an urgent task to promote further energy conservation in order to achieve the goal of reducing greenhouse gasses determined by each country. Among them, as absorption refrigerators widely used in offices, buildings, etc. mainly for business use, it is expected that triple-function absorption refrigerators with higher energy-saving properties will be popularized. [0003] The triple-effect absorption refrigerator has three regenera...

Problems solved by technology

[0005] However, if one pump is used to send liquid to three regenerators, a pump with high head and large flow is required

Moreover, since the necessary head of the pump is determined by the internal pressure of the high-temperature regenerator with the highest pressure, in order to adjust the inflow of the dilute solution to the medium-temperature regenerator and the low-temperature regenerator, it is necessary to install a valve equivalent to the inlet of the two regenerators. The pressure loss components (valve, etc.) of the pressure difference between the high temperature regenerator and each regenerator, which forms an energy loss
