The specific embodiment
Thermal conduction study basic theory in Thermal Power Engineering specialty: analyze heating system heat transfer process, ignore radiation heat transfer process, thermal convection principle is only discussed:
Rely on the motion of fluid, the phenomenon that heat is delivered to another place by a place, is called convection current.If the fluid that has quality m (Kg/ ㎡ .s) in convection process flows to temperature t 2 places by the place of temperature t 1, the heat of convection action transmission should be:
Q=mc (t2-t1) dimension W/ ㎡ ... formula-1
In formula: q: be unit are thermal discharge dimension W/ ㎡
M: be heat transferring medium quality dimension kg
C: be specific heat dimension W/kg
T2-t1: heat exchange ambient temperature differences dimension ℃
In Convective Heat Transfer, be one and be subject to the complex process of multifactor impact perhaps, heat supply heat carrier inner-walls of duct again in conduction heat transfer process, so existing heat convection has again conductive force in heat exchanging process, so existing conduction heat exchange is had again to the simultaneous process of heat convection, become Convective Heat Transfer, be called for short heat release.Its basic calculating formula is that newton propose for 1701: (derivation slightly)
Q=△ t/Ra dimension W/ ㎡ ℃ ... formula-2
In formula: Ra is convection heat transfer thermal resistance dimension ℃/W
According to newton's thermal convection principle formula, the operation principle of " device " exploitation is discussed: after building is completed, its radiation loss substantially constant constant (year illumination hourage), with reference to the relevant space heating phase indoor temperature standard of country, take civilian house as example: indoor 18-22 ℃.Constant 18 ℃ of indoor temperature of setting, secondary network heat supply temperature are 95 ℃, and according to formula-2, can calculate required heat exchange amount is that Q is put; But heating period is subject to the meteorological variable effects such as region wind-force, wind direction, sunshine hour number, one day 24 hours outdoor temperature, institute thinks 18 ℃ of constant temperature in holding chamber, thermal loads can constantly change, bring larger fluctuation to the normal operation of heating system, quote thus a Thermal Meter and detect in real time the variation of outdoor temperature, this instrument is referred to as: outdoor temperature sensor, it is by the record continuous temperature variation tendency of a day, measured temperature is connected into curve, be referred to as temperature curve.According to temperature real-time measurement curve, formulate the controlling run scheme that regulates.
Because regulating to regulate to control with other thermal parameters, temperature has certain difference, unlike fast as the response speeds such as pressure P, liquid level L, temperature rise and fall have hysteresis characteristic, therefore quoting fuzzy control theory in temperature adjustment process is applied in heating system, for heating system is operated steadily, heat energy partition equilibrium reduces fluctuation and is regulating the following control program that regulates of employing on control strategy:
(1) change at times variable temperature control with varied flow control program
(2) classical manual adjustments scheme (being different from manual adjustment).
