The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a kind of common transducer air conditioning functional block diagram at present, and depositing all of the generation of its compressor target frequency, operational factor and protection parameter accomplished by indoor controller.Indoor single-chip microcomputer calculates the real-time frequency shelves that compressor should move according to the temperature difference of detected room temperature and design temperature; Simultaneously also will according to outdoor electric circuit inspection to calculation of parameter such as electric current, delivery temperature, coil temperature go out the peak frequency limit value of operation; But could in indoor sassafras memory write EEPROM, find the pairing frequency values of this type then; And deliver to outdoor according to certain communication protocol frequency values; By outdoor controller driving frequency translation circuit, make compressor operating on this frequency.When off-premises station or off-premises station need be upgraded, the variation of indoor set or off-premises station all can produce new operational factor, therefore all can need indoor set and off-premises station to upgrade simultaneously and could satisfy Matching Relationship.This causes serious hindrance to model change.
Fig. 2 is the functional block diagram of the utility model, and it is on the basis of existing technology, and the generation of compressor operating frequency, operational factor and depositing of parameter of protection all are placed on the outdoor controller, is accomplished by outdoor CPU or DSP.Referring to Fig. 3, control method is following:
Indoor control section sampling indoor environment temperature, indoor coil pipe; Receive remote signal and push button signalling; The state of setting according to remote controller comes control room internal fan motor speed, puts the swing state of wind stepper motor; Control the start-stop of the auxilliary heat of electricity according to the pattern of setting and indoor coil pipe and the setting temperature difference, show the failure code under indoor temperature or design temperature and the malfunction, simultaneously according to predetermined communication protocol reception outdoor data and to outdoor transmission data.The data content that sends has contents such as indoor present mode of operation, indoor environment temperature, indoor design temperature, indoor heat exchanger coil temperature, indoor malfunction, indoor air velocity; The data content of indoor reception has contents such as off-premises station state, off-premises station fault.
Outdoor control section sampling outdoor environment temperature, delivery temperature and outdoor heat exchanger coil temperature; Detection system running current and voltage; The operation of control cross valve and outdoor fan motor; The Driven Compressor converting operation receives the signal of indoor set transmission simultaneously and outdoor running status and malfunction is sent back to indoor set.
After outdoor control system receives the data that indoor set sends; At first from communication, take out operational mode; Judge that machine operates in refrigeration, running status such as dehumidifies, heats and still be in holding state, as if being in holding state, off-premises station is then waited for operating state signal always; If running statuses such as freezing, dehumidify or heat; Outdoor DSP calculates the frequency shelves that move according to the temperature difference of design temperature and environment temperature, compares with the current maximum running frequency shelves that parameter limited such as delivery temperature, coil temperature, running current and input voltage again, gets minimum frequency shelves as actual motion frequency shelves.Pairing frequency values of running frequency shelves and delivery temperature, coil temperature, outdoor environment temperature, current parameters, voltage parameter all are placed among the outdoor EEPROM the concrete limit value of frequency, and each is also inequality for the parameter that different machine types is deposited.Through the pairing concrete frequency values of the frequency shelves that read EEPROM; The sine wave and the produced simultaneously triangular carrier that are produced this frequency by dsp processor carry out the copped wave processing; Obtain PWM voltage with same frequency sine wave characteristics; This voltage removes to drive intelligent frequency conversion module IPM again, thereby obtains the electric current through compressor coil same frequency.
When the temperature difference changed, the frequency values that calculates is respective change also, and the PWM waveform of generation is followed variation, thereby the compressor operating frequency also changes thereupon, reaches the purpose of change of frequency.
