Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but the utility model is not limited to listed example.
Refer to Fig. 1, a kind of heating energy-saving self-con-tained unit, comprise control cabinet 1, in described control cabinet 1, be provided with heating energy-saving nonshared control unit 11(PLC controller) and multiple control loop terminal 12, 13, 14, described control loop terminal 12, 13, 14 are connected with the respective ends of described heating energy-saving nonshared control unit 11, the signal gathering for transmitting field instrument, to described heating energy-saving nonshared control unit input switch amount signal and output relay control signal, on-the-spot executive component (magnetic valve is controlled in output solenoid valve control signal and output, electric control valve and frequency converter) control signal.
In described control cabinet 1, fluid level controller 20 and humidity detector are installed, split tube leakage monitoring for heat exchange station, described fluid level controller 20 is by detecting electrode connecting power line
The isolation modular converter 19 of the interference for preventing on-site signal is installed in described control cabinet 1, comprises temperature transmitting module and isolation distributor.
Breaker 22 and supply socket 21 are installed, for controlling the power on/off of each functional module in casing and power supply being provided in described control cabinet.
Further, in described control cabinet 1, be provided with a transformer 15, provide operating voltage for AC 220 V power supply being changed to 24 volts of power supplys into the functional module of each electricity consumption in control cabinet.
The utility model by being provided with heating energy-saving nonshared control unit in control cabinet, by relevant parameter, the signal of described heating energy-saving nonshared control unit acquisition process, export corresponding control signal, control corresponding relay, magnetic valve action, and then two stage pump that heating system is used, small pump, circulating pump, electric control valve etc. are controlled automatically, thereby realize the automatic control to heating system, realized unmanned.
In addition, there is a large amount of physical quantitys in each heat exchange station, as analog quantity parameters such as temperature, pressure, flow, liquid levels, all can carry out Real-time Collection and data processing to these parameters by the utility model, and show on the panel of the utility model device.
Use after the utility model device, each heat exchange station can be according to the variation of outdoor environment by regulating the aperture of electrically operated valve of a pipe network to control in time the supply and return water temperature of secondary pipe network, by regulating given curve, guarantee operational factor is moved all the time in given scope.
The automatic operation of heat exchange station can be followed the tracks of the variation of outdoor environment fast, in the time there is large variation in outdoor environment, secondary pipe network supply and return water temperature also and then changes simultaneously, the indoor temperature that ensures heating user is more balanced all the time, avoid heat supply network temperature hysteresis, greatly improved heat supply service quality, when outdoor environment is higher by day, reduced heating load simultaneously, so just can save a large amount of heats and electric weight, reduce heating network operation cost.
