Problems solved by technology
However, since it takes a certain amount of time for the temperature of the solution to drop to the crystallization temperature, as in the absorption chiller described in Patent Document 1, if the dilution is started when the concentration of the solution is equal to or higher than a predetermined value, the solution will not reach the crystallization temperature. There is time for crystallization, but dilution is still taking place, so when the absorption chiller is restarted before cooling down to crystallization temperature, the energy required for dilution is wasted, and it takes time to initiate

Embodiment Construction
[0034] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same or similar code|symbol is attached|subjected to the same or similar reference numeral to each other in each drawing, and a redundant description is abbreviate|omitted.
[0035] In this specification, an "absorption refrigerator" is an absorption refrigerator that cools or heats a temperature-adjusted fluid by supplying a heat source to the regenerator to constitute an absorption cycle based on a regenerator, condenser, absorber, evaporator, etc. A general term for a heat source machine, including: an absorption refrigerator, a machine that supplies a heat source to a regenerator to form an absorption refrigeration cycle and supplies cold water (cooled temperature-adjusting fluid), and supplies a heat source to a regenerator to form an absorption cycle and supply cold water (cooled temperature-regulated fluid) and / or hot water (heated temperature-regu...

The present invention provides an absorption refrigerating machine that efficiently dilutes an absorption liquid, a control program, and a control method for the absorption refrigerating machine. The absorption refrigerator that cools or heats the temperature-adjusted fluid through the absorption cycle of the absorption liquid and the refrigerant is equipped with: a solution pump that circulates the absorption liquid inside; a refrigerant liquid mixing part that can switch the liquid direction of the refrigerant Mixing / non-mixing of the system in which the absorption liquid can be circulated; the grasping part of the value related to the concentration of the absorption liquid grasps the value related to the concentration of the absorption liquid; the control device controls the solution pump and the refrigerant liquid when the heating source is stopped. The mixing unit is configured to operate the solution pump and / or perform the cooling of the refrigerant liquid by the refrigerant liquid mixing unit when the absorption liquid concentration-related value grasped by the absorption liquid concentration-related value grasping unit is equal to or greater than a first predetermined value. Dilution operation of the absorption liquid is performed for mixing, and when the value is less than the first predetermined value, the dilution operation is not performed and the operation standby state is set.
Description
technical field [0001] The present invention relates to an absorption refrigerating machine, a control program, and a control method for the absorption refrigerating machine, and more particularly, to an absorption refrigerating machine, a control program, and a control method for the absorption refrigerating machine that efficiently dilute an absorption liquid. Background technique [0002] Absorption refrigeration machines, such as absorption chillers, which cool or heat the temperature-adjusted fluid by means of an absorption cycle between the absorption liquid (solution) and the refrigerant, operate in a state where the slave machine is at a high temperature and the concentration of the absorption liquid varies When the absorption refrigerating machine is stopped due to a decrease in load, etc., in order to prevent the crystallization of the absorbing liquid, the absorption refrigerating machine is usually operated for a certain period of time to dilute the absorbing liqu...
