Description
Technical field
The utility model relates to a kind of control device of air conditioning.More particularly, the utility model relates to a kind of electronic dynamic discharge balance of intelligent temperature control, high accuracy, integrated device of computer networking monitoring charging three technology that is applied to the central air-conditioning fan coil.
Background technology
Central Air Conditioner Used in Buildings operation power consumption accounts for about 65% of the total power consumption of building, but there am a large amount of energy waste phenomenons in we when entreating air-conditioning in actual use, this wherein no doubt has factors such as user's awareness of saving energy is thin, the charge system is unreasonable to cause, but main cause is still because the backwardness of our design, construction and equipment operation management standard.Pursue the meterage of air conditioner cold-heat amount simply if do not improve the control technology level of air-conditioning system, this obviously is that the waste that self-technique level backwardness causes has been imputed to the consumer.Therefore, how to carry out central air-conditioning terminal control technology, the paid more and more attention of energy-conserving and environment-protective, efficient natural.
For the needs of sustainable development, the cold and hot amount measurement technology of fan coil intelligent temperature control technology, computer networking of central air-conditioning must be kept Total tune, the consistent development with air conditioner water dynamic balance technology.
The fan coil temperature control technology of no network communication function is very ripe at present, a large amount of indoor thermostats that use generally adopt the manual switchover of refrigerating/heating pattern, blower fan three fast manual modes to switch, and electric two-way valve is judged the realization automatic switch control according to room temperature.But its price will be very expensive when in a single day this class indoor thermostat needs to increase some combined network communication functions, be difficult to promote the wider application.
The state-of-the-art technology of fan coil cold and heat quantity metering can be divided into three major types: 1. running time the aggregate value method of weighting algorithm: 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 truly the temperature difference and the measurement mechanism of flow, and air-conditioning system is with scientific basis that season, load variations was revised without any metering.Error in dipping will be bigger when the air conditioner water force unbalance, also cause the significant wastage of the energy simultaneously.2. wind side temperature difference flow accumulation method: this method is based on the empirical equation of thermal technology's theory, by the anti-cold/heat that calculates the water side that pushes away of air quantity, the air enthalpy difference of measuring air side, this method theory novelty, design is unique, theoretical feasible, existing multinomial patent of invention.But device is too complicated, and reliability is low, be difficult to Industry Promotion and popularization and application.3. water side temperature difference flow accumulation method: this metering method is very perfect in theory, and the precision height is reliable, and the tandem product of a lot of maturations is arranged 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 three kinds of mechanical vane type, electromagnetic type and ultrasonic types.Wherein mechanical vane type calorimeter is the flow that is converted into water by the rotating speed of turbomachine, by internal structure by easily to excellent single channel formula, multithread bundle formula and the standard movement multithread Shu Shisan kind of can being divided into again.Because of in the mechanical vane type calorimeter miniature rotatable parts being arranged,, and require of the damage of supporting installation filter with defence impurity his-and-hers watches to having relatively high expectations of aqueous medium.This class energy meter scale 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 energy meter meter mainly depends on the certainty of measurement of discharge and the differential temperature survey precision of pairing temperature sensor, and the moving component of wherein measuring flow influences measuring accuracy because of damaging, stopping up easily; The measurement of water temperature difference is adopted 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 general, and 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, the water temperature difference designing and calculating standard of central air-conditioning chilled water system has only 5 ℃ after all, and the error of heat will reach 10% when there is 0.5 ℃ of temperature difference in systematic survey.Similarly, when the waterpower of air-conditioning coil pipe water system is uneven, not only can cause a large amount of wastes of the energy, and because of overcurrent also can cause method 3., 2. error in dipping increases the increase of the table meter lost of life and hydrodynamic noise.
If on the water pipe of fan coil system electric two-way valve, flow balance valve, energy meter scale are all installed, not only site space does not allow, and construction costs also can significantly increase.
The present known a kind of electronic dynamic discharge balance of intelligent temperature control, high accuracy, incorporate system integration device of computer networking charging three technology that is applied to the air-conditioning draught fan coil pipe of also not finding.
