Under：
Firstth, energy type household cost allocation algorithm：
Energy type household cost allocation is applied in multiple on-line system, by calculating machine cooling heat or heating load reality in user side
OK.
In formula (6), Q is interior machine semen donors or heating load, and τ is the time；Denominator is the energy of all interior machines under multiple on-line system
Amount change and.
Fig. 2 is the system construction drawing of machine in multi-connected machine in one embodiment of the invention.The present invention does not change existing interior machine knot
Structure, does not increase cost.Wherein, 1 is interior machine heat exchanger；2 is electric expansion valve；3 is inner blower；T1 is liquid pipe temperature sensor；
T2 is tracheae temperature sensor；T3 is environment temperature sensor.If from air self heat change calculations, only known into wind-warm syndrome
Degree, does not have leaving air temp, and the program is unworkable.If from refrigerant self heat change calculations, it is known that interior machine refrigerant inlet/outlet pipe temperature
Degree, electronic expansion valve opening, but the calculating of interior machine inlet/outlet pipe enthalpy, cold medium flux is related to pressure value.Because of the interior machine peace of each user
Holding position is different, there is refrigerant pressure loss, and to ensure the accuracy of user side energy balane, pressure value can not be by the height of outer machine
Pressure, low pressure replace (outer machine system is equipped with high pressure sensor and low pressure sensor).Existing interior machine system can not possibly be further added by pressure
Sensor, so the program is also unworkable.
From heat convection angle, incoming air and finned tube exchanger the quantity of heat convection can be calculated using formula (7), it is public
Formula (7) is as follows：
Incoming air and fin the quantity of heat convection, it is known that incoming air temperature (i.e. indoor environment temperature), heat exchange area F,
Arrives stream wind speed, copper pipe outer surface mean temperature (because interior machine copper pipe wall thickness is in 1mm, being approximately refrigerant mean temperature in pipe),
Still need to obtain convection transfer rate K.
From nusselt number Nu (formula 8), convection type difference is plunderred outward, then the relation of nusselt number Nu and reynolds number Re
Formula is different.Computation model is reduced to plunder tube bank outside incoming air, such as Fig. 3, then the relation such as formula of nusselt number Nu and reynolds number Re
(9,10), inquiry data can determine that C, m value.
D characteristic lengths in formula (8), referred to copper pipe external diameter；λ is thermal conductivity factor, referred to air conduction coefficient.
Nu=CRem (9)
Formula (9) is that the formula fitted by lot of experimental data, i.e. premise have determined that Pipe bundle structure, it has been assumed that C, m are
Constant, formula has been determined, and then under the Pipe bundle structure of the structure, the value of C, m is determined by lot of experimental data.C, m are constant value,
Big I is tabled look-up, (in-line arrangement and fork row, tube pitch and centre-to-centre spacing) relevant with the form of tube bank.
U in formula (10)∞Represent the speed of incoming flow of air；D represents characteristic length, referred to copper pipe external diameter；υ represents air
Kinematic viscosity.
Formula 8-10 is substituted into formula (7), then can obtain the quantity of heat convection calculating formula for formula (11) and (12)：
In formula (11), ε is that pipe arranges correction factor, is more than or equal under conditions of 10 in pipe row, and ε is 1；If pipe row
It is not equal to 1 less than 10, ε.The pipe row of usual indoor set heat exchanger is less than 10.
In formula (12), density, G be air quantity (volume flow), A be indoor set heat exchanger return air inlet faces of the ρ for air
Product.
