Background technique
Central air-conditioner is the common equipment of megastore, pharmaceutical factory, intelligent building building mansion.It can improve people's work and living environment.Improve people's life and health level, but central air-conditioner also is the equipment of energy consumption maximum in the building.It has brought huge energy consumption also for the operation of building when bringing comfortable internal environment to modern architecture, and according to statistics, the energy consumption of central air-conditioner has accounted for about 50% of building energy consumption.Existing central air-conditioning system still adopts easy control apparatus mostly, does not possess the intelligent control function, can not regulate the chilled water flow automatically according to terminal load variations, causes a large amount of energy wastes.
Summary of the invention
The purpose of this utility model is, for overcoming disappearance and the deficiency that above-mentioned prior art exists, and propose a kind of can be according to central air conditioning equipment total electricity consumption (consumers such as each water pump, main frame have all been installed telemetering electric meter, are used for monitoring real-time power consumption) and terminal load variations and regulate the switch type intelligent control cabinet of central air-conditioner cold (heat) pump motor operation frequency.The utility model comprises teletransmission intelligent electric meter, three-phase air circuit breaker, A.C. contactor, direct digital controller, DC electrical source, two-phase air circuit breaker, auxiliary reclay, frequency variator, reactor, upper mounting plate, lower installation board, rack.
Wherein: be equipped with on the top of rack that upper mounting plate, middle part are equipped with lower installation board, the teletransmission intelligent electric meter is installed on the cabinet panel, be convenient to check at any time.The heat radiation of frequency variator and the integral heat sink in the cabinet are convenient in the installation of staggering in cabinet of upper mounting plate and lower installation board like this.Two-phase air circuit breaker, direct digital controller, DC electrical source, auxiliary reclay are installed on the guide rail that is fixed on upper mounting plate, three-phase air circuit breaker, A.C. contactor are installed in the left side of lower installation board, frequency variator is installed in the right side of lower installation board, with air circuit breaker side by side, reactor is installed in the frequency variator downside.
This intelligent control cabinet can switch to any water pump operation in two.Both can under the frequency conversion state, work, reach purpose of energy saving, network failure occur, also switch to original control cabinet control, under the power frequency state, work in case change equipment.Can not influence the normal operation of equipment.
When this water pump intelligent power saving control cabinet is used for freezing (heat) water Energy Saving Control, freezing (heat) water flow that direct digital controller will collect, house steward is for backwater pressure reduction, the main frame outlet temperature, process variables such as house steward's supply and return water temperature, and the flowmeter of system's installation, differential pressure pickup, temperature transducer, the consumer electric weight detects, deliver to the computer main control cabinet, the computer main control cabinet is according to the data of being gathered, comprehensive all factors, according to so-and-so algorithm, calculate the accurate Control Parameter of output, the computer main control cabinet is delivered to direct digital controller with output parameter, direct digital controller removes to regulate the real-time output frequency of freezing (temperature) pump variable frequency again, the rotating speed of control of pump, change the temperature difference that its flow makes freezing (temperature) water system, supply and return water temperature, the flow of pressure reduction operates under the most energy-conservation mode, because the dynamic control of freezing (temperature) water system, realized that the air-conditioner host cold medium flux follows the changes in demand of terminal load, make air-conditioning system under each load condition, can both both guarantee the travelling comfort of terminal temperature difference, save the conveying energy consumption of freezing (temperature) water again to greatest extent.
This water pump intelligent control cabinet is used for cooling water system when control, and when ambient temperature or air conditioning terminal load change, the cooling water entry and exit temperature of central air conditioner main machine will change thereupon, and main frame efficient also changes thereupon.Direct digital controller is monitored telemetering electric meter the electricity consumption situation of main frame in real time, the variation that cooling-water temperature sensor that system installs and outdoor temperature humidity sensor will wait these parameters, direct digital controller is according to the real time data of being gathered, be sent to the host computer control cabinet, host computer control cabinet utilization cooling water system system optimizing control model, calculating main frame cooling water the best goes out, inlet temperature, and with sensor monitors to cooling water go out, inlet temperature optimum temperature parameter is therewith made comparisons, the Control Parameter that output is optimized is given direct digital controller, regulate the output frequency of cooling waterpump frequency conversion, control cooling waterpump rotating speed, the flow of dynamic adjustments cooling water, make advancing of cooling water, outlet temperature is approached given optimum value, thereby the assurance central air conditioner main machine is at any time under the optimal conversion efficiency and moves, cooling waterpump is lower than under the rated load through being everlasting moves, realize water pump and main frame power-saving running, reach purpose of energy saving.
