Cluster controlled heat pump hot water system

Abstract

The invention discloses a heat pump hot water system for ensuring continuous water supply by using a cluster control technology, aiming at solving the problem in the traditional heat pump control system. Each module machine and a main control cabinet can be communicated bidirectionally and all module machines can be communicated bidirectionally, wherein the main control cabinet is used as a center node to form a star topology network with each module machine, and all module machines form an annular topology network. When one module machine abnormally operates, the main control cabinet can be immediately subjected to operation regulation; and when working conditions change, a unit can be conveniently subjected to self-adaptive regulation. When the main control cabinet is in failure, intelligent control units in all module machines are coordinated to realize system control.

Description

technical field [0001] The invention relates to a heat pump hot water system, in particular to a heat pump hot water system which uses cluster control technology to realize cooperative control of multiple module machines. Background technique [0002] At present, the conventional large-scale heat pump hot water system is mostly in the form of multi-unit parallel connection. In terms of control, an independent control cabinet is usually set up, and then through the one-way communication mode, the output of the switching value is used to control the start and stop of the corresponding module unit to achieve the purpose of control. However, the disadvantages of such control are also very obvious, because the control signal is transmitted in one direction, and the failure of the module machine cannot be effectively fed back to the control cabinet, which makes the operation reliability of the equipment poor and the effective water supply cannot be guaranteed.
