Description

The heating system energy saver
Technical field
The utility model relates to a kind of central heating device, is a kind of heating system energy saver specifically.
Background technology
Present heat supply circulating pump adopts the heat pump oepration at full load, controls the flow that loops back through controlling opening of valve, and this pattern causes the loss of a large amount of electric energy.And; Equipment such as water circulating pump, small pump major part is artificial local operation; Do not realize control automatically, all devices all needs manual operation, and the validity of manual adjustment lags behind equipment state all the time and changes; Can't reach the purpose of energy savings and operating cost, also consume a large amount of costs of labor simultaneously.Though disposed sensors such as temperature, pressure on the pipeline, be merely and upload the data use, fail according to this parameter adjustment circulating pump rotating speed; Circulating pump one start; Just, can not in time adjust the confession pressure of return water to move under the 50Hz full load situation, and no matter what of actual needs heat; Its possibility of result causes the water system most of the time all under high pressure, big flow, the little temperature difference, to move the serious waste energy.
Summary of the invention
The technical problem that the utility model will solve is to provide a kind of simple in structure, easy to operate to above-mentioned deficiency, and can adjust the rotating speed and the heating system energy saver of realizing unattended function of circulating pump and small pump according to actual conditions automatically.
For reaching above purpose; The technical scheme that the utility model adopted is: the described heating system energy saver of the utility model comprises heat exchanger, be connected heating network on the heat exchanger, be connected circulating pump, circulating pump VFC cabinet on the heating network; It is characterized in that: the output of said circulating pump VFC cabinet is connected to the control end of circulating pump; The input of circulating pump VFC cabinet is connected to the heat supply signal output part of heat energy controller; The signal input part of heat energy controller connects the pipe pressure sensor of registering one's residence respectively, register one's residence pipe temperature sensor, return pipe pressure sensor, return pipe temperature sensor, outdoor temperature sensor; The said pipe pressure sensor of registering one's residence is installed on the pipeline of registering one's residence of heating network with the pipe temperature sensor of registering one's residence; Said return pipe pressure sensor and return pipe temperature sensor are installed on the water return pipeline of heating network, and said outdoor temperature sensor is installed in outdoor.
Small pump also is installed on the said heating network, and the control end of said small pump is connected to the output of small pump VFC cabinet, and the input of said small pump VFC cabinet is connected to the moisturizing signal output part of heat energy controller.
Adopted the heating system energy saver of this structure; Simple in structure, easy to operate, and can confirm heating load, rapid adjustment heating equipment automatically according to actual conditions, heat energy dropped into more when period, heating load was big; Stablize the heat energy input after reaching balance; Whole system also adopts Redundant Control, has really realized unattended function, is adapted at various big or middle heat supply runnings place and uses.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
As shown in Figure 1; This heating system energy saver comprises heat exchanger 4, be connected heating network on the heat exchanger 4, be connected circulating pump 2,3 and small pump 6,7 and circulating pump VFC cabinet 1 on the heating network; The output of said circulating pump VFC cabinet 1 is connected to the control end of circulating pump 2,3; The input of circulating pump VFC cabinet 1 is connected to the heat supply signal output part of heat energy controller 5; Have five signal input parts of gathering signal on the heat energy controller 5 at least; The signal input part of heat energy controller 5 connects the pipe pressure sensor P1 that registers one's residence respectively, pipe temperature sensor T1, return pipe pressure sensor P2, return pipe temperature sensor T2, outdoor temperature sensor T3 register one's residence; The said pipe pressure sensor P1 that registers one's residence is installed on the pipeline of registering one's residence of heating network with the pipe temperature sensor T1 that registers one's residence, and is used for gathering the pressure and temperature signal of registering one's residence and managing respectively; Said return pipe pressure sensor P2 and return pipe temperature sensor T2 are installed on the water return pipeline of heating network, are used for gathering the pressure and temperature signal of return pipe respectively; Said outdoor temperature sensor T3 is installed in outdoor, is used to gather the outdoor temperature signal.
In addition, the control end of small pump 6,7 is connected to the output of small pump VFC cabinet 8, and the input of said small pump VFC cabinet 8 is connected to the moisturizing signal output part of heat energy controller 5.
This heating system energy saver adopts outdoor environment temperature collection and compensation technique to confirm required heating load, has reduced the heat-energy losses that the blindness heat supply brings; Aspect heating equipment, according to set institute's calorific requirement, the mode comprehensive adjustment of utilization vector converter technology and temperature, two kinds of feedbacks of pressure; When the circulating backwater temperature is low; The servo control valve of the steam of performing fighting improves the pump operating cycle frequency and makes it operate in the high energy output mode,, indoor temperature little when the recirculated water supply backwater temperature difference near or when reaching desirable heat supply temperature; Turn down the servo control valve of steam; And reduce the pump operating cycle frequency, and make it operate in power save mode, just reached the heat supply balance; In addition for design heat supply power saving apparatus, on the pipeline of the delivery port of heat pump and water return outlet, distinguish mounting temperature sensor, the temperature signal of two-way temperature sensor collection is input to differential temperature controller; Differential temperature controller shows temperature approach; Can set temperature difference reference value, and receive the analog input port of frequency converter, gather signal to pressure transmitter through the PID controller simultaneously exporting signal; Receive the analog input port of frequency converter, the running frequency of automatic control and adjustment heat pump exporting signal; Consider the loss of recirculated water, on pipeline, have small pump, in good time moisturizing when insufficient pressure, thus both guaranteed the pressure of pipeline, also guaranteed heating effect.
