Abstract

The invention relates to a multiunit concentrated remote control system of a solar energy and air source heat pump hot-water project. The system comprises a programmable logic controller, a personal computer (PC), an operating parameter detection module, a solar collecting system controller, an air source heat pump hot-water unit controller, a constant pressure water supply controller, a scene display and a remote control computer. The system has the advantages that the PC is combined with a programmable logic controller (PLC), and a good human machine interface (HMI) and a remote monitoring function are provided for the system due to usage of the PC, so that operations are more convenient and intuitive; the automation degree, the control accuracy, functionality, the anti-interference performance and reliability of the whole system are improved due to the usage of the PLC; and a good using effect is achieved in the control system through combination of the PC and the PLC.

Description

technical field [0001] The invention relates to a multi-unit centralized remote control of a solar air source heat pump hot water project. Background technique [0002] At present, the existing projects combining solar water heating units and heat pump water heating units are all controlled by some simple hardware, which has shortcomings such as low control accuracy, unsatisfactory system operation stability, and insufficient use of solar energy; in addition, the original Some systems cannot remotely monitor heat pump water heating units and solar water heating units. The control time and place have obvious limitations, and the user is not convenient enough to operate the control system. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-unit control system for solar air source heat pump hot water engineering with constant pressure water supply, high control precision, convenient remote maintenance and excel...
