Abstract :
A restaurant is located 8 sets of solar heat pump hot water unit. Each of the solar collector area is of 50 m2. The power input of each heat pump is of 25 kW. The running parameters of solar heat pump hot water unit need to be written to PLC by network, the unit can run smoothly according to use´s order. At the same time, one can monitor the solar heat pump hot water unit running conditions. Based on TCP / IP protocol of Siemens PLC and Beijing Kunlung Tongtai Monitor and Control Generated System (MCGS), computers applying MCGS software can communicate solar heat pump hot water units by Siemens PLC. The authors make design and debug according to the plan. Eight equipment is composed of network successfully. They have run two years steadily without error. It decreases the start times of heat pump and improves energy efficiency and meet the user´s order. The design plan is rational.
