佰富彩Product advantage

The design of the professional

Set the thermal mechanical, process instrumentation, network communications, such as electrical control design, can provide according to different user heat-exchange unit for the optimal design of hardware and software, tailored to different working conditions, in order to meet the user's requirements.

Quality is more stable

Industrialized production, design, production, testing, and strictly comply with ISO9001 international quality system, covering design control, procurement control, production process control, finished product inspection and product safety control in each process, to ensure the quality of heat exchange unit is stable and reliable.

More cost-effective

Compact structure, can greatly save room area and the capital cost, the factory has strict testing before the scene just flange connection, the boot can be put into operation, reduce the installation cost, shorten the construction period.

佰富彩Operation management easier

Humanized human-computer interface, convenient operation and management. Advanced and mature control system, low failure rate, less maintenance, energy saving, no one can really realize their duties safe operation and remote monitoring.

The working principle of

Adjust the way

佰富彩In pieces quality, and the adjustment By adjusting the primary side of heat flow to change secondary side water supply temperature of circulating water. The control program of secondary side water supply temperature and outdoor temperature sensor signal, adjust the opening of a side of electric control valve, change of heat flow, achieve the purpose of regulating heating system heat load, save heat energy.

佰富彩In pieces the adjust by frequency converter to adjust the flow of the secondary side water circulating pump, achieve the purpose of regulating heat load. Saves the operation cost, but easy to cause hydraulic disorder.

In pieces quality regulation By electric valve adjustment of heat flow, at the same time, through the inverter to adjust water circulating pump, secondary side flow implementation secondary side water temperature, flow rate adjustment at the same time, this way can save heat energy, power, and convenient management.

Hydrating way

The constant pressure in pieces filling water Using constant pressure tank for filling water constant pressure system. Water pressure in the system to reach the upper or lower limit, can pass the pressure tank to control the opening of pump stop, make the system pressure temperature fluctuation is small.

佰富彩In pieces frequency filling water On the secondary side return pipe pressure sensor as pressure signal, the controller according to the signal through the inverter to control the rotation speed of pump, to achieve the purpose of changing flow.

The control mode

佰富彩HZ intelligent heat exchange unit controller by monitoring the outdoor temperature and the primary side and secondary side of pipe network pressure, temperature, flow rate and the parameters such as current, voltage, power, control the opening of the primary side regulator to secondary side circulating pump, pump speed and the number of running pumps, etc., central heating quality of the good social effect and purpose of economic operation of the heating power station operation, low cost. According to the needs of users, we can provide three different kinds of control mode: manual control b automatic control c remote control

佰富彩Meet the control scheme of different user needs

Han adai heat-supply regulating experts using the world's most advanced German Siemens intelligent control system, and in combination with the practical condition of Chinese heat, secondary development, provide the best solution for the different needs of users.

The temperature control scheme

佰富彩Experience set out by the outdoor temperature change and adjustment curve, temperature compensation, automatic control electric control valve, a side secondary side water supply temperature control, in order to meet the heat load change, achieve energy saving and comfortable operation.

佰富彩Automatic unattended control scheme

Through a network of electric control valve control the secondary water supply temperature, and can undertake outdoor temperature compensation function, according to the second network for back pressure or temperature as a feedback signal, circulating pump adopts frequency conversion control, secondary network to realize variable flow control, so the heat exchange unit can be in "large temperature difference, little flow" operation energy saving condition. According to the secondary network backwater pressure as feedback signal, pump adopts frequency conversion hydrate; Fill the tank liquid level sensor can automatically control the water level, and has low level protection function; Secondary backwater pipe pressure solenoid valve can be mounted to the system, such as secondary water pressure more than the set value, electromagnetic valve automatically opens automatically shut down after pressure relief to the TVC; Good unit after startup according to preset program to run automatically, managers need to regularly inspect the unit.

佰富彩Remote monitoring automatic unattended duty control scheme

Choose the control mode of heat transfer units in addition to have more control function, also has a remote communication function, can choose different ways of communication: cable (telephone dial-up, ADSL, broadband communications, etc.) or wireless (GPRS, etc.), and supports a wide range of communication protocol (Ethernet, the PPP protocol, TCP/IP protocol, etc.). Through the communication mode, can put the heat exchange unit primary side and secondary side temperature, pressure, flow rate, the outdoor temperature and indoor temperature, the circulating pump and pump running state and running frequency, the electric control valve opening unit parameters, such as real-time uploaded to the central station, or connected with building automation system (BAS), on-line monitoring, the operational status of the heat-exchange unit with water high temperature alarm, low water pressure alarm, low water level alarm, water pressure to overpressure alarm, overpressure automatic relief, power automatic protection and linkage, etc. By monitoring center of upper machine and field control of two-way communication, managers can optimize the control parameter setting, remain the best state to ensure heat exchange unit, everything can be mastered.
