Abstract: Aiming at the requirements of operation parameters detected and controlled for the solar air heat pump multiheatsource hot water system(SAMW), a design method of the visualization remote monitoring and control (VRMC) system based on energy management has been put forward with taking the optimal energy efficiency ratio as the design goal.The experiment platform of VRMC system was constructed with PC and PLC as the control core, and its monitoring software was developed by CenturyStar. The test results show that the operation of the VRMC system is stable and reliable, and the operating conditions parameter of SAMW system can be automatically detected,stored, analyzed and controlled, so as to realize reasonable allocation of heat load, improve thermal efficiency and technical document management level.

Key words: solar air heat pump multiheat source hot water system(SAMW);visualization remote monitoring and control(VRMC); energy management; thermal efficiency
