Device thermostat 7 acts on but dynamic.Wave-like line 16 is clear that actual loading incoherent with actual flow rate.
Straight line 15 is caused according to the flow controller 9 independent of pressure of the present invention by introducing.
Fig. 5 B shows the situation according to the present invention, and wherein flow depends on return temperature and controlled, the most according to demand
Or load controls flow.This obtains the flow rate 17 more mated with actual demand, and therefore obtains more efficient system.
System shown in Fig. 2 shows the simple-arranged of the present invention, and wherein the flow rate of operation flow controller 9 is arranged
Actuation means 10 is any kind of thermostat known in the art, and therefore this system is automatic.Temperature controller 11 is by directly
Receive actuation means 10 in succession.
This layout tool has the advantage that, it is not necessary to can coverlet for any additional-energy source of operation and each standpipe
Solely regulate.Standard thermostat well known in the art being used as actuation means 10 and gives following advantage further, this device leads to
Often including the mechanism arranging temperature set-point, therefore, the set point returning temperature can be according to dependency the most as shown in Figure 4
Regulate.
Fig. 6 shows such embodiment, the heat friendship during wherein all sensors 8,9 and 19(measures main supply line 1
Change the temperature sensor of the temperature of medium) and flow controller 9 or alternatively actuation means 10 be connected to electronic controller
18, described electronic controller is adapted for recording temperature and regulates flow individually.Introduce this electronic controller 18 to give
Many advantages relative to automatic actuation means.
Electronic controller 18 includes the required mechanism for electronic controller 18, because these mechanisms are electronic controller necks
Known to territory.
The set point returning temperature can be automatically adjusted according to actual state by electronic controller 18, and is automatically implementing
In mode, the set point returning temperature is generally manually set.This gives energy-conservation huge probability, this is because this system meeting
The set point returning temperature is optimized according to Optimal Curve 13 as shown in Figure 4.
In this electronic form principle, supply temperature is controlled (" surpassing " controls) by external temperature measurement.Based on these
" surpass " control action, return temperature set-point and be controlled to properly arrange so that optimize the performance of this system the possible whole year, therefore
This performance is not dependent on system load (external temperature)." secondary " of the flow in standpipe controls the individual collections with radiator 6/vertical
Pipe load is relevant, and therefore that flow is relevant to heat demand, and thus by this single-main distribution from conventional constant flow system
It is changed into the variable flow system of at a relatively high efficiency.
Another advantage is, electronic controller 18 allows monitoring and records temperature and for controlling and the stream of system monitoring
Amount, in order to optimize systematic parameter over time and on one's own initiative.
In order to protect the pump of this system, in the case of whole standpipes are all closed, electronic controller 18 is an embodiment party
