Abstract

The utility model provides a flow-self-adaptive hot water heating and heat-exchange unit, belonging to the field of heat exchange equipment for cell heat exchange stations. The heat-exchange unit is realized by arranging a flow meter at the water supply port of a secondary pipe network, and constituting a flow-self-adaptive control device by the flow meter, the existing pressure transmitter, a circulating water pump, a frequency converter and a controller. Due to the adoption of the heat-exchange unit, the room temperature can be adjusted according to the requirement of a heat user, and temperature, pressure and particularly flow causing the change of heat supply are adjusted automatically, and the aims of supplying heat as required, metering separately, saving energy and bringing convenience in use are fulfilled reliably. Moreover, the flow-self-adaptive hot water heating and heat-exchange unit has the advantages of simple design structure, high adaptability, stable running, suitability for popularization in the industry, and the like.

Description

Adaptive-flow hot water heating heat exchange unit
Technical field
The utility model belongs to a kind of heat-exchange apparatus of hot water heating, especially for minute heat-exchange apparatus of the sub-district heat exchange station of family heat metering.
Background technology
At present, the heat metering is carried out in domestic residential houses, the developing direction that temperature will become heat supply market is controlled at the branch family voluntarily, and various places household based heat metering work is being set about carrying out.Yet, existing heat exchange unit, be temperature, the pressure sensor (also claiming transmitter) that is provided with by on controller, heat exchanger, pipe network, secondary pipe network and first and second pipe network, and the constant pressure supply water device that the electric control valve that connects of pipe network and secondary pipe network are made up of frequency converter, small pump and magnetic valve is formed.Should say that this heat exchange unit can change the aperture of controlling electric control valve voluntarily according to indoor and outdoor temperature, and automatic water supplement or sluicing when ductwork pressure changes.For good positive role has been brought into play in user's central heating.But this heat exchange unit can not be regulated room temperature voluntarily according to each user's needs, during secondary pipe network generation changes in flow rate, can not realize adjusting automatically and dynamic adaptivity of mating the inconvenience that certainly will cause the waste of the energy and use.
Summary of the invention
The purpose of this utility model provides a kind of adaptive-flow hot water heating heat exchange unit, to realize the automatic adjustment of the secondary pipe network hot water circuit water yield, adapts to the needs of hot user's household metering and branch family regulation and control, remedies the deficiency of prior art.
The technical solution of the utility model is as described below: this utility model comprises pipe network water supply mouth, water return outlet, secondary pipe network feed water inlet, water return outlet, controller, heat exchanger, temperature transmitter, pressure transmitter, electric control valve, frequency converter, water circulating pump, small pump and magnetic valve, it is by in the secondary pipe network feed water inlet flowmeter being set, and is made up of jointly with existing pressure transmitter, water circulating pump, frequency converter, controller flowmeter that the adaptive-flow control device realizes.
The beneficial effects of the utility model: because this utility model has been taked said structure, can regulate room temperature according to hot user's demand, and will cause temperature, the pressure that the heat supply changes, particularly flow automatically adjusts, and reliably realizes heating according to need, household metering, energy savings, goal of the invention easy to use.This utility model also has advantages such as project organization is simple, adaptive performance is strong, unit operation is stable, suitable popularization in the industry.
Description of drawings: Fig. 1 is an adaptive-flow hot water heating heat exchange set structure schematic diagram.
The specific embodiment: adaptive-flow hot water heating heat exchange unit shown in Figure 1, be that heat exchanger 3, electronic mediation valve 15, primary side feed water inlet 23, water return outlet 9 are connected to form pipe network one time with the primary side thermal source, and water circulating pump 4, flowmeter 19, secondary side feed water inlet 1 and the secondary survey time mouth of a river 2, user 20 and hot water heating pipe network are connected to form secondary pipe network.Its temperature control is imported the outdoor temperature transmitter 10 that control ends are connected by field controller 6 and with controller 6, the temperature transmitter 13,14,11,12 that connects on controller 6 input control end to first and second pipe networks, the controller 6 output control terminals composition that is connected with electronic mediation valve 15 control ends; The control of its pressure is by controller 6 and be connected frequency converter 5,17 and the magnetic valve 18 that the pressure transmitter 21,22,7,8 on controller 6 input control end to first and second pipe networks is connected with controller 6 output control terminals, and water circulating pump 4, small pump 16 compositions; The control of its adaptive-flow is by controller 6 and be connected flowmeter 19, the pressure transmitter 7,8 of controller 6 input control ends to the secondary pipe network, the frequency converter 5 that controller 6 output control terminals connect and be made up of the water circulating pump 4 that frequency converter 5 is regulated.Described controller 6 is S7-400 or S7-500 programmable logic controller (PLC).
During the work of this heat exchange unit, according to Changes in weather, outdoor temperature transmitter 10 and first and second pipe network temperature transmitter 13,14 and 11,12 detect variations in temperature, signal is sent into controller 6, controller 6 is according to control program, send the aperture of the electronic mediation valve 15 of instruction control, guarantee that heat exchanger secondary side import and export mean temperature is in the setting value operation.Meanwhile, pressure transmitter 21,22 and 7,8 detects first and second ductwork pressure value and sends into controller 6, and when secondary pipe network pressure was lower than setting value, the frequency conversion constant pressure supply water was carried out in frequency converter 17, small pump 16 work.When force value was too high, the magnetic valve of being controlled by controller 6 18 was opened, and unnecessary water is leaked into water tank.When user 20 regulated room temperature, flowmeter 19 detected the secondary pipe network hot water flow and changes, and signal is sent into controller 6, according to programme-control, sent instruction and gave frequency converter 5, carried out the frequency control of water circulating pump 4, realized the pump capacity adjustment.Controller 6 is given in pressure transmitter (7,8) detected pressures variation simultaneously, according to programme-control, regulates water circulating pump 4 rotating speeds, realizes the pump head adjustment.
The utility model can be realized heating according to need, and how many system's how many flows of actual needs, water circulating pump 4 just initiatively export, and reach adaptive-flow.And each customer flow changes the percentage unanimity; Guarantee that system's dynamic adjustments element action is very little or motionless, not fragile.Its power savings is also very remarkable simultaneously, and compared with prior art power saving rate can reach 30~60%.
