Building Management Control
Brief Introduction With the MRV air conditioner Energy consumption management system HCM- 03A, which use a protocol converter to transfer all parameter values of the air conditioner system to a computer, the user can monitor the operating state and electric energy consumption status of outdoor and indoor units of the air conditioner system on the monitoring computer, conduct various settings including parameter setting in time, realize individual control, group control, and schedule control of indoor units, receive the alarm information from the air conditioner system in a real time and take corresponding countermeasures, and create various energy consumption report forms according to the corresponding processing data. This control system is used for the following air conditioner All models: MRV series. Device required for this control system 1. Protocol converter IGU02: It is responsible for converting the protocol of the air conditioner system into RS485 protocol for output, receiving the ammeter pulse signals, calculating and storing the Energy consumption for the connected air conditioner system, and transferring the Energy consumption to the computer. 2. Protocol converter HA-MB164AD, HA-MA164AD: It is responsible for converting the protocol of the air conditioner system into 485 protocols for output. 3. HCM-03A: It includes hardware and software, The hardware is a small MAC minicomputer and serial to Ethernet converter; the software which is a manmachine interface used for display and control of air conditioner parameters; it can collate and store Energy consumption and output Energy consumption report forms, and can realize remote monitoring, etc. though a LAN and the internet. Control range 1. For installation of air conditioner sets requiring an air conditioner management system, the number of indoor units of each air conditioner system shall not be more than 40; Otherwise, the protocol converter will not be able to operate normally. 2. One PC have 4 RS485 ports, each of which can be connected with at most 20 converters, so one control system can control at most 80 converters. 3. The maximum number of indoor units controlled by one control system is 4*20*40 = 3200. It is recommendable to make the number of indoor units less than 1500.
