Abstract
A single indoor set power consumption figure display process of frequency changing one-to-many air conditioner is disclosed that contains: initial phase; voltage and current detection phase; performance calculation phase; display phase. The performance calculation phase calculates the power consumption of every indoor set via rating formula. Said rating formula is :X<SUB>i</SUB>=X<SUB>i-1</SUB>+t=10 t=1 U<SUB>t</SUB>I<SUB>t</SUB>*C<SUB>i</SUB>/t=A t=1 C<SUB>t</SUB>;Said display phase contains power consumption display and indoor temperature display. The invention realizes that many indoor sets with one outdoor can separately calculate the electric charge by simple control program of the outdoor set on the foundation of the unchangeable present circuit constructer. It can make the users using indoor set to monitor the power consumption figure timely.
Description
Technical field
The present invention relates to a kind of frequency conversion one one driven multiple air conditioner.When particularly relating to the shared off-premises station of a kind of many indoor sets, can calculate the separate unit used for indoor machine electric weight display packing of frequency conversion one one driven multiple air conditioner of the employed electricity charge of each indoor set respectively.
Background technology
Air conditioner is a kind ofly to make its inner refrigerant carry out the refrigeration of being made up of compression process, condensation process, expansion process and evaporation process or heat the round-robin device.When air conditioner carries out refrigeration cycle, compressed machine compression and the refrigerant that becomes high-temperature high-pressure state can dispel the heat to the outside in condenser, and when flowing through expansion valve, significantly reduce its temperature and pressure, this low temperature, low pressure refrigerant absorb heat when flowing through the evaporator of indoor set, flow back in the compressor again after becoming the refrigerant of high-temperature low-pressure.Usually, air conditioner is divided into separate type air conditioner and wall-through type air conditioner, and separate type air conditioner then includes an one driven multiple air conditioner that is made of an off-premises station and Duo Tai indoor set.
Fig. 1 is an one driven multiple air conditioner structural representation.Fig. 2 is the structural representation of frequency conversion one one driven multiple air conditioner off-premises station.
As shown in Figure 1, an one driven multiple air conditioner mainly comprises an off-premises station 1 and Duo Tai indoor set 2～N.Off-premises station 1 is provided with refrigerant efferent duct 6 and refrigerant input pipe 7, then is provided with refrigerant input pipe 8 and refrigerant efferent duct 9 on the indoor set 2～5, and corresponding continuous with the refrigerant pipe of off-premises station.Liquid refrigerants from off-premises station 1 will offer every indoor set 2～5 by the refrigerant efferent duct 6 of off-premises station 1 and the refrigerant input pipe 8 of each indoor set 2～5.Enter the refrigerant of indoor set 2～5 will be respectively with each interior space in air carry out heat interchange, the refrigerant that becomes gaseous state through heat interchange will focus on the refrigerant input pipe 7 of off-premises station 1 through the refrigerant efferent duct 9 of indoor set 2～5 and flow back in the off-premises station 1.
As shown in Figure 2, the off-premises station of frequency conversion one one driven multiple air conditioner includes: the outdoor heat converter 230,240 that can carry out heat interchange with outdoor air; Be used for the suction chamber outer air, and can make this air and the outdoor fan 201 that carries out heat interchange by the refrigerant of outdoor heat converter 230,240; Refrigerant can be compressed into compressor 210a, the 210b of high-temperature high-pressure state; The refrigerant that assurance offers compressor 210a, 210b is the fluid reservoir 270 of gaseous coolant; Can prevent to enter the dividing plate 202 of compressor 210a, 210b and fluid reservoir 270 setting areas by the outdoor air that outdoor fan 201 sucks.Also include expansion valve 250a, 250b, oil separator and four-way valve (not shown) etc. Expansion valve 250a, 250b are corresponding with outdoor heat converter 230,240, and are installed in a side of outdoor heat converter 230,240.Therefore compressor 210a, 210b can change the heating capacity of air conditioner by constituting with the constant speed compressor 210a of certain speed rotation and the variable speed compressor 210b that can change rotational speed.
But an one driven multiple air conditioner is that different users uses same off-premises station, and particularly at present for frequency conversion one one driven multiple air conditioner, its control method is just simply controlled start → initialization → indoor temperature and shown as shown in Figure 3.When different users uses same off-premises station, can not calculate respectively for the power consumption of every indoor set, and the user can not see the energy-saving effect of inverter air conditioner with respect to the constant speed air conditioner intuitively.
Summary of the invention
Technical matters to be solved by this invention is, when the shared off-premises station of a kind of many indoor sets is provided, can calculate the separate unit used for indoor machine electric weight display packing of frequency conversion one one driven multiple air conditioner of the employed electricity charge of each indoor set respectively.
The technical solution adopted in the present invention is: a kind of separate unit used for indoor machine electric weight display packing of frequency conversion one one driven multiple air conditioner includes: initial phase; Voltage, current detecting stage; The power calculation stage; The demonstration stage.The described power calculation stage is to calculate every indoor set institute wasted work rate by rating formula.
Described rating formula is:
The described demonstration stage includes power consumption display and indoor temperature shows.
The separate unit used for indoor machine electric weight display packing of frequency conversion one one driven multiple air conditioner of the present invention, on the basis that does not change existing circuit structure, by simple off-premises station control program, calculate the power consumption of each indoor set, and pass to respectively on the corresponding indoor set, and on the display of indoor set, show by communication protocol.Make many indoor sets of a shared off-premises station can realize calculating respectively electricity cost.Use the user of each indoor set can monitor the power consumption of air-conditioning in real time.
