HIMOD flagship series was developed by the company in early 1999 including the new type of energy saving and modular HIMOD series of temperature and constant humidity air conditioning and MICROFACE controller. It retains the advantages of HIRANGE series, and also increases a lot of new high technology achievements. The HIMOD series products in late 1999 in China and Europe also began selling, by the new and old customers praise.
Design of HIMOD flagship series
HIMOD flagship series is used the modular design. The cooling capacity for the basic module of HIMOD flagship series is from 20kW to 40KW. It divides into five models that have 8 kinds of refrigeration system. Different from other manufacturers, HIMOD series product can be combination of modules according to the needs of users of different cooling capacity. Each system can accommodate the most module number of 16. Each module of a system has its own MICROFACE controller. The user can set the parameters of each module through the MICROFACE.
Single cooling loop and double cooling loop HIMOD flagship series of precision air conditioning, the refrigeration capacity is from 20KW to 103KW for a single unit which can be combined together. It can satisfy the use at the present stage and can adapt to the needs of future development with a very wide range of applications. It uses an advanced microprocessor control technology that fully meets the requirements for the environment of precision control in the computer room. A controller can complete the timing switching and fault switching for units. It also centralizes the management which is convenient for air conditioning system. Humidification system of HIMOD flagship series is detachable electrode tank type humidifier.
In order to adapt many areas of poor water quality, it adopts the control technology which is unique and the use of “fuzzy logic” control software. It can be based on the conductivity of the water current and automatically adjust the value of the electrode. At the same time, it can be determined according to the hardness of water and flushing times for the humidification tank. The humidifier is removable. To clean the humidifier can be continued to use, on the one hand, can prolong the service life of tank. On the other hand, it can make the humidifier that has the highest efficiency. Therefore, it can be used in the electrical conductivity of water that is particularly high environment — often in remote areas.
HIMOD flagship series uses interactive “type V” coil, the internal thread copper tube and punched slotted fin, and heat transfer efficiency is higher than the traditional coil unit. The “V” structure of coil can make refrigeration system cycle match the refrigeration load, the gas flow through the coil surface is smooth, and the “V” structure of coil also reduces the noise.
So we can see the design idea of HIMOD flagship series, consider not just now, but in the future, specific features are as follows:
HIMOD 系列旗舰型的微处理控制器配有带背景灯的MICROFACELCD显示器，正常情况下，可以显示回风的湿度和湿度及机组的序列号，设定点的温度和相对湿度，和工作状态显示(制冷、加热、加湿、去湿)，风机状态以及各种报警。Hiromatic图形控制器图形显示最近48小时内的温度和相对湿度的曲线，友好的用户操作菜单界面可以使操作人员很方便的对系统和报警状态进行查询及消声，例如：高温、低温、高湿、低湿、气流丢失、更换过滤器、压缩机超高压报警等等。具备多级密码保护功能，包括设定点的改变、报警阀值的设定、通讯的设置及机组的设置等项目都可以通过密码保护。内置的电源节省功能可以在输入电源低于允许的设定电压范围时自动关闭机组。安装在控制板上的备份电池可以当主电源出故障时，保存机组的设定参数和历史记录。模块化HIMOD 系列旗舰型的每个模块都有独立的内部控制器，并且可以根据现场情况，将各模块通过备选组件连接。当某一模块出现报警时，自动启动备用模块，并且可以使模块循环工作，平衡各模块的使用时间。Hiromatic图形控制器通过RS232接口可以连接和PC机，可以监控到机组的所有数据。如采用了远程的PC机及调制解调器后可实现机组的远程监控。开放通讯软件方便的与主要的(BAS)楼宇自动控制系统相连接，例如：JOHNSON，HONEYWELL 等。
The Micro processing controller of HIMOD flagship series is equipped with MICROFACELCD display with backlight under normal circumstances that can display the sequence number of moisture and humidity, the set point temperature and relative humidity, the working state display (refrigeration, heating, humidification, and dehumidification), fan status, and alarm. Hiromatic graphics controller displays the last 48 hours of temperature and relative humidity curve. The user-friendly menu allows the operator to easily query the state of the system. For example: high temperature, low temperature, high humidity, low humidity, air flow loss, replacing the filter, compressor high pressure alarm etc. Multilevel password protection function includes the set point changes, the alarm threshold settings, communication settings, and unit setting items. Built in power saving function is allowed automatic closing unit when the input power is reached the range of setting voltage. Backup battery installed in the control board recording the parameters of units prevents when the main power supply is failure. Each module of the modular HIMOD flagship series has internal controller independently, and according to the environmental conditions, each module is connected by the alternate component. When a module has alarm, the controller automatic starts standby module. The controller can also balance the cycle time of module. Hiromatic graphics controller can be connected with PC through the RS232 interface for monitoring all data sets. By using the PC on site and the modulator can realize the remote monitoring for the unit. Open communication software is convenient for connecting to the building’s control system, for example: JOHNSON, HONEYWELL, and etc.
HIMOD 系列旗舰型的所有日常维护工作都可以在机组的正面完成，所有的部件都可以从机组的正面取出来。HIMOD 系列旗舰型模块的空气过滤器可以从机组的正面进行更换。在机组正常运行的情况下，可以对制冷系统进行检修。
All the routine maintenance work of HIMOD flagship series can be accessed in front and all parts can be taken out easily. Air filter can also be replaced in front. Under the normal operation condition, the maintenance of the refrigeration system can be carried out.
Various cooling methods: Because the design of HIMOD flagship series is very flexible, it can be utilized in a variety of ways of cooling.
In order to ensure the whole system is reliable and efficient, the suitable air condenser is used according to the environment temperature of outdoor. In order to prevent the intrusion of moisture and impurities in the transport process, the unit has been in the factory pre filled with dry nitrogen. In the installation of unit should pay attention to set pipe and the liquid pipe, according to the distance of the condenser, choose suitable specification and in accordance with the requirements of copper tube.
Flexible installation is suitable for all occasions. Modular design adapts to the special ground handling, can be applied in the field of professional disassembly, and it can go through the narrow stairs, corridor, and elevator.
