Abstract

The invention relates to a solar central hot water engineering control system. The solar central hot water engineering control system is characterized by comprising a device part and a controller; thedevice part comprises a solar heat collecting module, a water tank, a plurality of electromagnetic valves, a plurality of water pumps, a plurality of water pipes and an auxiliary heating device; thesolar heat collecting module and the water tank are connected through a water pipe A provided with the corresponding electromagnetic valve and the corresponding water pump; the auxiliary heating device and the water tank are connected through a water pipe B provided with the corresponding electromagnetic valve and the corresponding water pump; the solar heat collecting module and the water tank are each provided with a cold water entering water pipe C provided with the corresponding water pump; the controller comprises an MCU, a power supply power source module, a sensor module, an operation and processing module, a storage module, a control output module and a communication module; the controller is connected with the device part through a sensor; the sensor transmits an acquired signal to the MCU; and after processing of the operation and processing module, instructions are sent out through the control output module and the communication module to correspondingly control the electromagnetic valves and the water pumps in the device part. The solar central hot water engineering control system is flexible and advanced in structure.

Description

technical field [0001] The invention relates to the field of heat utilization control, in particular to a multi-mode solar energy central hot water engineering control system based on solar energy. Background technique [0002] The solar central hot water engineering control system undertakes the monitoring and control tasks of the operation site, and its function and quality directly affect the operation performance of the hot water system. Most of the existing solar water heater control systems or central solar central hot water engineering control systems adopt customized solutions, that is, design different control strategies according to different user needs. The utility model patent (authorized announcement number CN 204421402 U) proposes a solar water heater control system, which can detect and display the water level and water temperature of the water storage tank, and has the functions of preventing electricity leakage and preventing dry burning. The invention pate...
