Description
Technical field
The present invention relates to the electromechanical integrated device of the terminal control of a kind of central air-conditioning.More particularly, the present invention relates to a kind of integral intelligent metering control device that is applied to air-conditioning draught fan coil pipe temperature control technology, cold and hot amount measurement technology, the electronic dynamic discharge balancing technique of high accuracy.
Background technology
The HVAC power consumption accounts for about 65% of the total power consumption of building in the building system, how to carry out the central air-conditioning technology of energy-conserving and environment-protective, efficient natural, paid more and more attention.In northern China, the heating energy consumption index is 3～5 times of developed country under the similar weather conditions, no doubt have in the reasons of a large amount of wastes of energy consumption that user's awareness of saving energy is thin, the charge system can not stimulate factors such as energy-conservation, but chief reason is still because the backwardness of our design, construction and operational management standard.Pursue the meterage of air conditioner cold-heat amount simply if do not improve the technical merit of system, this is that the waste that self-technique level backwardness causes is passed on to consumers, and is obvious so unreasonable, and has run counter to the principle of fair and just.For the needs of sustainable development, the terminal temperature control technology of central air-conditioning, cold and hot amount measurement technology and hydraulic equilibrium technology must be kept Total tune, the consistent development.
The fan coil temperature control technology of no communication function is very ripe at present.The general room temperature controller (comprising mechanical type, electronic type) of a large amount of import brands generally adopts the manual switchover of refrigerating/heating pattern, blower fan three fast mode manual switchovers, and electric two-way valve is judged the realization automatic switch control according to room temperature.But in case need to increase some intelligentized specific function prices will be very expensive.In China, high-end temperature controlling machine power technology integrated apparatus and the Related product with independent intellectual property right still very is short of (as: blower fan three fast the integrated of functions such as controls automatically, the automatic switchover of refrigerating/heating pattern, intelligent network communication, multimedia liquid crystal display that circulate).
At present, the known principle that is used for the metering of the cold and hot amount of central air-conditioning can be divided into three major types: 1. simple cumulative method of time, at present a lot of based on the patented technology and the product of this method, but its measuring accuracy is very low, do not have temperature (or temperature difference) truly to measure and flow measurement device, and air-conditioning system is with scientific basis that season, load variations was revised without any metering.When air conditioner water pipe network system instability, or waterpower when uneven error in dipping will be bigger, cause the significant wastage of the energy simultaneously.2. wind side temperature difference flow accumulation method, this method be based on the empirical equation of thermal technology's theory, by the air quantity of measuring air side, the anti-cold/heat that calculates the water side that pushes away of enthalpy difference of air side, and this method theory novelty, design is unique, domestic existing patent of invention.But only measuring technique and the device price with regard to air mass flow is very expensive, and certainty of measurement is subjected to the influence of various engineering uncertain factors easily.If with the anti-air quantity that pushes away of voltage, the error of calculation can be very big simply, even under same voltage, the air air quantity also influences certainty of measurement because of mounting means, service condition.The measuring accuracy of obvious this method is not high yet, and device is too complicated, and reliability is low, be difficult to popularize application.3. water side temperature difference flow accumulation method, this metering method is very perfect in theory, the measuring accuracy height, stable and reliable operation has the tandem product of a lot of maturations at present.Cold and heat meter based on this principle mainly is made up of flow sensor, pairing temperature sensor and integrator three parts.Press the difference of flow sensor form, this class energy meter also is divided into mechanical vane type, ultrasonic type and three kinds of models of electromagnetic type.Wherein mechanical vane type calorimeter is the flow by the tachometric survey water of turbomachine, by internal structure by easily to excellent single channel formula, multithread bundle formula and the standard movement type multithread Shu Shisan kind of can being divided into again.Because in the mechanical vane type calorimeter miniature rotatable parts are arranged,, usually require of the damage of ancillary filter device installing with defence impurity his-and-hers watches to having relatively high expectations of aqueous medium.But because of its measuring principle relative with structure simple, cheap, precision is general, widely applied in the metering of fan coil at present.And the small-bore energy meter of ultrasonic type and electromagnetic type seldom is applied to the end metering of fan coil because of all multifactor restrictions such as price, technology.
According to the error theory analysis, the certainty of measurement of this small-bore mechanical vane type table meter mainly depends on the certainty of measurement of discharge and the differential temperature survey precision of pairing temperature sensor.Wherein the moving component of flow measurement influences measuring accuracy because of damaging, stopping up easily; The measurement of water temperature difference is adopted common thermal resistance sensor (as: precision of common PT500 or PT1000 series is about 0.25 ℃) and is become to send by two-way and calculates temperature approach, precision is not high, and because the thermometric uniformity of thermal resistance sensor is relatively poor, when one of them sensor generation upper deviation, another sensor generation lower deviation, the relative accuracy of differential temperature survey will be lower, and the supply backwater temperature difference designing and calculating standard of central air-conditioning chilled water system has only 5 ℃ after all.Similarly, when air conditioner water pipe network system instability, or during hydraulic misadjustment, method 3., error in dipping 2. also can increase, and cause a large amount of wastes of the energy.If in fan coil system water side motor-driven valve, balanced valve, energy meter are all installed, site space does not allow yet, and construction costs also can significantly increase.
Present known a kind of integral intelligent metering control system device that is specifically applied to the temperature control technology of central air-conditioning fan coil, cold and hot amount measurement technology, the electronic dynamic discharge balancing technique of high accuracy of also not finding.

Cv＝Cv(s)
The pressure drop Δ P at spool 304 two ends acts on the power on the spool 304 and the elastic force F balance of spring 306, and we adopt the stainless steel spring with linear deformation characteristic, and elastic force F is the linear function of displacement s (being amount of spring compression), and Δ P also is the function of displacement s.
Suppose the top projected area Ap (belonging to constant) of spool 304, initial elastic force F
0, K is the elastic modelling quantity of spring 306, they have following relational expression: they have following relational expression:
F＝K×s+F
0＝ΔP(s)×Ap
The flow-passing surface of wing passage 311 belongs to face of cylinder perforate (when spool 304 is circle), so the flow-passing surface area A can be passed through the expanded view cartographic represenation of area:
