Embodiment
The inventive method is further elaborated with reference to embodiment and accompanying drawing:
A kind of section thermal center electricity regulation and control method of direct-connected unit in height area, comprises the following steps:
Step 1, gather outdoor temperature generation and calculate supply and return water riser;
Step 2, gather actual supply and return water temperature and form actual supply and return water riser;
Step 3, actual supply and return water riser controls high area with calculating supply and return water riser by pid control mode Return pipe is powered to the two of upper installation and moves valve opening, and then controls height area unit hot water flow, and it is anti-to form mean temperature closed loop Feedback control, realize section heat regulation and control;
Step 4, the change of the dynamic valve opening of two energizations described in step 3, causes pressure of supply water to change, is run for steady pressure, constant pressure The frequency variable circulating pump of power control, change the power consumption of circulating pump in a manner of passive flux changes, realize circulating pump economize on electricity regulation and control;
Foregoing invention method uses dynamic thermal load control mode, supply and return water riser is calculated according to outdoor temperature, with reality After border supply and return water temperature compares, it is powered using pid control mode control two and moves valve opening change, is adjusted average warm for backwater Degree, because the heat dissipation capacity of radiator is directly proportional to mean temperature difference, user house is sent to equivalent to have adjusted according to outdoor temperature In heat, make the indoor temperature that is influenceed by outdoor temperature stable.It is so-called to meet heat user demand, it is exactly when outdoor temperature liter Gao Shi, reduce supply and return water riser, the heat being sent in user family is reduced;When outdoor temperature reduces, it is averaged for backwater Temperature raises, and the heat increase being sent in user family, the heat constantly changed with outdoor temperature, indoor temperature can be kept steady It is fixed.
At the same time, the change of the dynamic valve opening of two energizations, causes height area unit changes in flow rate, makes to transport in constant-pressure mode Row operating mode Xia Gao areas circulation revolution speed changes, the flow that passive adaptation has changed and for.When the flow if reduced, rotating speed drops It is low;When the flow increases, rotating speed increase, because the most of the time is not design operating conditions, operating flux is less than design discharge, Therefore rotating speed is to reduce, it is possible to achieve power-saving running.
For convenience of adjustment thermic load, indoor temperature is set by the way of the setting of direct room temperature, after room temperature is set, all Operational factor all adjusts operation according to the room temperature of setting, meets the requirement of indoor temperature automatically.
Because indoor temperature, average supply and return water temperature, not only relevant with outdoor temperature, also with Air Infiltration and solar radiation Effect it is relevant, therefore Air Infiltration and the shadow of solar radiation can be perceived by the change of supply and return water riser of reality Ring, belong to dynamic load regulation and control method in this way, compared with regulating and controlling method with steady state load, what can be regulated and controled is more accurate, no Need in anomalous weather(Cool winds, snow)When manual intervention heating parameter.
