Description
Technical field
The present invention relates to a kind of household based heat metering regulation device, this device is according to " Energy Conservation Law of the People's Republic of China " the 38 article regulation, the requirement that energy saving building ' should install household-based heat metering device, indoor temperature regulation device and heating system regulation device ', the function of household-based heat metering and indoor temperature regulation integration can be realized, and provide possibility for reaching the distributed distributing system changeable flow adjustment of heat supply the whole network.This device also may be used for other users needing the regulation and control such as metered flow (heat) and temperature.
Background technology
" Energy Conservation Law of the People's Republic of China " the 38 article regulation: " country takes measures, and carries out household measurement heat-supplying step by step, according to the system of charging with heat to the building carrying out central heating.New building or carry out reducing energy consumption to existing building, should install heat metering device, indoor temperature regulation device and heating system regulation device according to the rules." State Council, relevant ministries and commissions and local government issue a series of about regulations, resolution and detailed rules for the implementation in succession.In ' three Norths ' area, carry out the popularization of heat metering technology just energetically.
At present, in the process promoting heat metering technology, normally three covering devices are installed respectively: heat metering device, indoor temperature regulation device and heating system regulation device, high, the inconvenient maintenance management of system complex, cost; Existing flow measurement adopts the indirect method of measurement, and accuracy and reliability are not high; Various room temperature control valve, all has restriction loss, affects energy-saving effect; Existing regulation device all can not be connected with the distributed transmission & distribution heating system of advanced person is organic.The existence of these factors, has become the technical bottleneck affecting heat metering Technique Popularizing.Household based heat metering regulation device merges into set of device above-mentioned three covering devices, not only cost low, constructability installation and maintenance management, and overcome above-mentioned all existing technology drawbacks, a therefore sound development of making greater efforts to promote heat metering technology popularization surely.
Summary of the invention
In order to solve the problem, the invention provides a kind of household based heat metering regulation device, be made up of displacement pump 1, motor 2, intelligent controller 3, there is household-based heat metering, room temperature regulation and control and the integrated function of system regulation.Wherein displacement pump 1 and motor 2 connect into entirety.
Key technology of the present invention is the several functions that comprehensive exploitation applies displacement pump 1: displacement pump 1 is volumetric method flow detector; It is again the active flow control device without restriction loss; Or the circulation power equipment of system.Wherein volumetric method flow detection determines according to motor 2 and the rotating speed of displacement pump 1, the discharge characteristic of displacement pump and application conditions.Intelligent controller 3 realizes following function: the rotating speed r, the user's supply water temperature t that gather motor 2 and displacement pump 1
gwith return water temperature t
h, circular flow L and the heating load H of user is determined according to displacement pump 1; Gather room temperature t
n, by regulating motor 2 and the rotating speed of displacement pump 1, changing flow L and heat H, making room temperature t
nauto-control is to setting value; Also there is the functions such as power module, display, setting, warning and communication.
The present invention is a kind of integrated innovation, wherein: the manufacture of displacement pump 1, motor 2 and driving, speed governing and temperature sensor are all mature technologies, all right choice criteria product had; The rotating speed of displacement pump 1 directly can obtain from the driver module of motor 2, speed probe that thus need not be special.Intelligent controller 3 also can adopt mature technology.Therefore, the present invention easily implements.
The kind of displacement pump 1 is a lot, and that such as commonly uses has piston pump, plunger displacement pump, membrane pump, gear pump, screw pump etc., can select according to flow detection required precision and application conditions.Apply the same with all water pumps, in order to ensure normal work, the static pressure point of necessary correct initialization system, to guarantee not vaporize in pump, and its materials and structures must can adapt to the requirement of heating hot water.
Motor 2 adopts alternating current generator and direct current generator, must can run continuously for a long time, be convenient to regulate, be convenient to gather rotating speed.Different with producer according to the kind of motor 2, control method, its driver module has three kinds of ways: be contained in intelligent controller, or be made of one with motor, or external.
Intelligent controller 3 adopts high integrated, highly reliable chip microprocessor, adopts mature technology as far as possible, except having the sampling of traditional controller, control, display, setting, warning and communication function, also must can complete following basic function:
(1) rotating speed r, the supply water temperature t of motor 2--displacement pump 1 is gathered
gwith return water temperature t
hparameter, according to discharge characteristic and application conditions determination water supply flow L=f (r) of displacement pump 1
Heating load H=f (r, t
g, t
h)
Thus provide accurate foundation for heat sharing and heat Calculation.
(2) room temperature t is gathered
n, regulate the rotating speed of motor 2-displacement pump 1, change flow L and heat H, and then auto-control room temperature t
n; Control strategy is not limit, and can adopt PID, fuzzy control etc.
(3) display parameters must have indoor temperature, heating load.Indoor temperature setting value can be set by the user, and other parameters are set by administrative staff.
The invention has the beneficial effects as follows:
Household based heat metering regulation device can realize the repertoire that " Energy Conservation Law of the People's Republic of China " the 38 article requires three devices (household-based heat metering device, indoor temperature regulation device and heating system regulation device) installed.Because displacement pump is booster pump, be again the flow control device without restriction loss, and be volume flow sensor.So this device is simply compact, reliable, cost is low, installation and maintenance convenient management.Flow measurement adopts volumetric method, than indirect method accurately and reliably.This device can promote the popularization of heat metering technology and distributed circulating heat supply system, to improving heating effect and building energy conservation is of great importance.This device also may be used for other heat user needing metered flow and temperature etc. to regulate and control.
