Description
Technical field
The utility model belongs to the air conditioner technical field, more particularly relates to the improvement from the charging type multi-split air conditioner.
Background technology
Present domestic existing air conditioner, detachable one one accounts for the overwhelming majority.Trace it to its cause, be that the one-to-one air conditioner is easy for installation, low price, technology content is lower thereby be suitable for production or the like.But the one-to-one air conditioner also has weak point: the one, and every family all has off-premises station to be installed on the exterior wall, and style, type, installation site have nothing in common with each other again, influence the appearance of the city, and the utmost point is not attractive in appearance.The 2nd, off-premises station is heavier, and its support is for a long time at outdoor wind and weather, and unavoidable corrosion in the course of time, jeopardizes personal safety.
In contrast to this, multi-split air conditioner is then with the obvious advantage: off-premises station is few, and the bed rearrangement building has only one or two, three promptly enough not affect the appearance substantially, and is also safer.But existing multi-split air conditioner can't measure the refrigerating capacity and the heating capacity of each family indoor set mostly, the electric energy and the electricity charge that also just can't accurately distribute each family to consume.Therefore, dispute takes place in two family house unavoidably.
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of refrigerating capacity and heating capacity that can accurately measure each indoor set is provided, and the electric energy and the electricity charge that also just can accurately distribute each family to consume avoid dispute to take place; And more attractive in appearance also safety from the charging type multi-split air conditioner.
Summary of the invention
In order to achieve the above object, the utility model is made of off-premises station, three above indoor sets and the pipeline that connects them.An EAT sensor and an air intake humidity sensor all are installed on the air inlet of each indoor set, a leaving air temp sensor and an air-out humidity sensor all are installed on the air outlet of each indoor set.The sensor all is connected on the control circuit of indoor set, and the control circuit of indoor set is connected with the central processing unit of off-premises station.Each indoor set all has the fourth gear wind speed, and the same shelves wind speed of different indoor sets is identical.Because indoor set air channel, fan, motor etc. are more stable, the fourth gear wind speed of indoor set can be demarcated and be the fourth gear air quantity.The user can be switched the indoor set air quantity as required, that is regulates the wind speed of different shelves.
The control circuit of indoor set is made of microprocessor and peripheral circuit thereof.Microprocessor is made up of the 89P502 type.The microprocessor performance of this model is good, low price, and it is better to be used for the multi-split air conditioner effect.
After each sensor was measured EAT, leaving air temp, air intake humidity, air-out humidity and five parameters of air quantity, the microprocessor of indoor set just can calculate refrigerating capacity and the heating capacity of sending into the room according to Study on Air Enthalpy Difference Method.The user then can regulate cold and the heat of sending into the room by changing design temperature and air quantity.
The enthalpy of air equals the product of specific enthalpy and MAF.Because indoor set adopts several different speed, so the mass rate of air can be demarcated in advance.The indoor set of two same models, the error of mass rate is very little.Therefore, the refrigerating capacity Q of separate unit indoor set can be calculated as follows:
Q＝Vr(H1-H2)/Vn(1+Xn)
In the formula: Vr........ indoor set air quantity
H1........ the air enthalpy of air outlet of indoor set
H2........ the air enthalpy of indoor set air inlet
Vn........ the specific volume of air on the air intake measuring point
Xn........ the water capacity of air on the air intake measuring point
Can find H1, H2 and Vn value under uniform temperature and the humidity by psychrometric chart.
The heating capacity Q of separate unit indoor set can be calculated as follows:
Q＝VmCpm(T2-T1)/Vm(1+Xm)
In the formula: the flow of Vm....... air
Cpm...... the specific heat at constant pressure of air
T2........ the air themperature of air outlet of indoor set
T1........ the air themperature of indoor set air inlet
Xm...... air water capacity on the air quantity measuring point
Total power consumption then is:
Total power consumption=voltage * electric current * time (KWH)
Wherein the time can measure once in ten minutes.
If an off-premises station drags a, b, four indoor sets of c, d, its refrigerated medium heat sum respectively is Qa=3000W, Qb=4000W, Qc=2000W, Qd=3000W, and its total refrigerated medium heat then is:
Q is total=3000+4000+2000+3000=12000W
As with single-phase 220V civil power, total current is 30A, and ten minutes total power consumption then is:
220V*30A*1/6＝1.1KWH
The electric weight of wherein sharing to a machine then is 1.1*3000/12000=0275KWH
The rest may be inferred, as can be known the electric weight of each household.Because of be calculated once in ten minutes, also needed add up in every month.
The indoor set principle is as follows:
The indoor set control microprocessor is made of 89P502.This chip functions is powerful, and independent telephone circuit interface is arranged.Can carry out remote telephone and information transmission.The indoor set circuit mainly is made up of following partial circuit: first is a sensor measuring circuit.Second portion is phone input and output.The 3rd for showing and electronic expansion valve controls.The 4th is communication.
First is a sensor measuring circuit.Sensor is changing according to external temperature or humidity resistance.Provide the change in resistance table by temperature sensor and humidity sensor producer.Precision is in 1%.As seen from Figure 2, the resistance R 123 that is connected together with sensor is 4.7K, precision 1%.The last terminal potential of R123 is changed with the variation of sensor.R122 and C122 form wave filter, and undesired signal is leached, and signal is sent in the microprocessor.The 11st pin of 89P502～the 16th pin carries out the calculating of cold and heat.
Second portion is phone input and output.Because microprocessor internal has complete phone DTMF circuit function, access port is by the map interlinking of CN11 socket.The 2nd pin of CN11 is the dtmf signal input.The 1st pin of CN11 is dtmf signal output.Be connected respectively to the 6th, the 7th and the 20th pin of 89P502.
Third part is for showing and electronic expansion valve controls.Be shown as the luminotron indication.Be mainly used in the running status and the indicating fault of air conditioner.The electronic expansion valve controls valve opening makes air-conditioner system energy operate as normal, and higher Energy Efficiency Ratio is arranged.Luminotron is connected respectively on the 60th～63 pin.Electric expansion valve is connected respectively on the 49th～52 pin of chip, drives electric expansion valve by driver LILN2003.
