The industrial air-cooled direct steaming type heat pump clean central air conditioner of the present invention is the continuous variation with environment temperature, indoor load, in time regulates the capacity of air-conditioning by its indoor and outdoor controller, eliminates a kind of flexible air-conditioning system of its influence.Its operation principle is: by indoor, outer controller is gathered indoor comfort parameter (temperature/humidity/air quantity/blast/resh air requirement), the state parameter of outdoor environment parameter and sign refrigeration system operation conditions, according to running Optimization criterion and the on-the-spot control criterion of setting of user, by changing the power that off-premises station starts means conditioning chamber external systems such as number, regulate refrigerating capacity or heating capacity continuously, and the fan of control air-conditioning system, electric expansion valve, all controllable component such as wind direction adjusting plate and magnetic valve, thereby guarantee the comfortableness of indoor environment, and make controlled air-conditioning system steady operation in optimum Working.
Existing industrial central air-conditioning exists system's power consumption big because system's employing water is the mode of secondary refrigerant, the big shortcoming of system's control inertia.Aspect indoor comfort: 1. the start and stop of compressor control realizes according to setting room temperature and last lower deviation, so it is constant that indoor temperature can not keep, can only fluctuate up and down at design temperature, the user can feel sometimes cold and sometimes hot in the temperature environment of fluctuation, very uncomfortable; 2. when the room thermic load was big, air-conditioner needed longer a period of time of experience just can reach design temperature, so the indoor uncomfortable time is longer from starting; 3. because system uses big capacity compressors to form, the frequent start-stop of compressor and indoor air velocity switch all can bigger system's pulsation.Aspect energy consumption: 1. compressor start and stop operation not only can reduce its service life, and makes refrigeration system exist bigger irreversible loss.Because geographical position, size, orientation and the construction material in room are different, its thermic load is also inequality, and more little when loading, the start and stop frequency of compressor is high more, and compressor and overall efficiency are also low more; 2. traditional air-conditioning system adopts start and stop control, and its seasonal energy efficiency ratio (seer) can not get improving at all; 3. compressor is when starting, and its starting current is 5 to 7 times of revolution electric current, all can be influential to indoor equipment and regional power grid.The industrial air-cooled direct steaming type heat pump clean central air conditioner of the present invention adopts and drags a control technology more, can fundamentally improve the defective that traditional air-conditioning system exists.Owing to drag an air-conditioning system according to the difference of room temperature/humidity/air quantity/blast and setting value and the situation of change of difference more, adopt the start and stop of indoor and outdoor controller control compressor and the rotating speed of number and fan electromotor thereof, can continuously change the flow and the heat exchanger air quantity of cold-producing medium in the system
The industrial air-cooled direct steaming type heat pump clean central air conditioner of the present invention has reduced the cost of system, has improved the reliability of system, has reduced the operating cost of system.The industrial air-cooled direct steaming type heat pump clean central air conditioner of the present invention, the characteristics of pressing engineering product are designed to the semi-custom mode.That is: the major function of main frame has been provided with in factory and has finished, and the partial function parameter is set at engineering site.The GMP control system adopts the notion of " object-oriented ", and each I/O module of its controller (body controller) all is core with CPU, collection software, and hardware is one, can carry out the special measurement and the control task that satisfy requirement of engineering.It is connected with special sensor, actuator, finishes a complete set of measure or control operation and corresponding data are handled and analyzed.For example, temperature-measuring module except that direct measurement temperature, humidity, also calculates the relative humidity of air thus.It also utilizes the Kalman filter technology that the survey data are handled, and guarantees finally to send the correctness and the reliability of parameter.When finding that sensor breaks down, it can also be reported to the police immediately.Again for example, blower fan/compressor control module, its constantly comprehensive monitoring motor operating state, and according to the order of being accepted in conjunction with the analysis of motor running status at that time to blower fan/compressor start, stop, control such as reduced-voltage starting.When finding that blower fan/compressor breaks down, this module is reported to the police automatically.Like this, or else directly corresponding one or several physical equipment of each I/O module needs the user that general I/O channel is carried out secondary development and configuration.Although each I/O module has become the special module of observing and controlling object,, can satisfy different specific (special) requirements as long as according to the controlled device of reality a plurality of I/O module spliced are got up on demand.Moreover the observing and controlling mode of each I/O module and all kinds of observing and controlling parameter all can be revised by user flexibility ground, make each special module of producing in batches have suitable application flexibility.Like this, the contradiction between the versatility of hardware-software product and each the observing and controlling special objects obtains organically unified.
The function of a field control unit can be divided into: the measuring transducer physical parameter; Determine control action by calculating or logic analysis; Commander's actuator is implemented these actions; By keyboard and display unit and local operator or maintenance personal's dialogue; By communication network and other control module and monitoring management machine exchange message.The control module of GMP body control system is assigned to these functions in the corresponding functional modules fully and realizes.Hardware, software and function three are unified in one in each module.Although these modules all are inserted in the control frame, each can work alone, warm swap, plug and play.This is the controller architecture design new ideas of " object-oriented ".
Use the GMP control system that a GMP air-conditioning/new wind/clean system is carried out observing and controlling, at first determine measuring and controlling equipment, select corresponding I/O module according to measuring and controlling equipment, need communication then to add a communication module again, add a computing module when needing to coordinate control, promptly constituted a site controlling computer.After the wiring energising, get final product work behind one step of the execution fitting operation.The special-purpose software owing to be cured in each I/O module, user technical staff need only check whether the acquiescence observing and controlling mode of each I/O module meets the requirements, need not extra work if all meet then; If have the person of not meeting then the observing and controlling mode of simple modification one lower module just can.What need that user technical staff carries out secondary development only is the control scheme of establishment main control module, with specific calculations and the logic judgement that realizes customer requirements.Because the I/O module has stronger observing and controlling function, the establishment of master control module controls scheme is fairly simple.The user works out the control scheme of main control module and can carry out at the monitoring management machine, by communication network the control scheme is downloaded to computing module.
