A kind of control method of air conditioner air-out temperature
Technical field
The present invention is a kind of control method of air conditioner air-out temperature, belongs to the renovation technique of the control method of air conditioner air-out temperature.
Background technology
Heating and air conditioner is in the time of heating operation, and in indoor air quantity one timing, air conditioner air-out temperature raises with indoor heat exchanger temperature T C, and with indoor heat exchanger temperature T, C reduces; Meanwhile, air conditioner air-out temperature reduces with the increase of air quantity, increases with the minimizing of air quantity.In the time that air conditioner heat-production moves, if when not anti-cold wind control, in the time that indoor heat exchanger temperature T C is lower, such as lower than indoor design temperature TS, just have wind that temperature is lower out, have a strong impact on user's comfortableness.The object of anti-cold wind control design is to make the air temperature of producing by boasting be unlikely to too low, prevents from blowing to human body sensory to cold.The temperature T E that supposes the anti-cold wind of indoor heat exchanger of setting is 30 DEG C, in the time that indoor heat exchanger temperature T C is less than 30 DEG C, enters anti-cold wind control, and indoor fan rotating speed reduces or stops.In the time that indoor heat exchanger temperature T C is greater than 30 DEG C, proceed to the rotating speed that user sets, this design can prevent that cold wind from blowing out.
This is technology recognized within the industry.
The anti-cold wind design of air-conditioner at present mainly contains three kinds of designs:
The first, not anti-cold wind control: cold wind can directly blow out;
The second, the anti-cold wind control of part: (such as 2 minutes) have anti-cold wind design in air-conditioner is opened certain hour, after unlatching certain hour (such as 2 minutes), not anti-cold wind control.This method for designing, in air-conditioner running, blows out because off-premises station frosting or other reasons have cold wind after causing indoor heat exchanger temperature to decline.
The third, whole process has anti-cold wind control, and still the temperature value of anti-cold wind is fixed, and indoor rotating speed is limited several rotating speeds after anti-cold wind, and the rotating speed of anti-cold wind differs larger.Therefore in the time turning to another anti-cold wind rotating speed control from the control of an anti-cold wind rotating speed, because rotation speed change is larger, cause indoor heat exchanger temperature T C significantly declining and having a larger rising with rotating speed, thereby may get back to original rotating speed control because of the rising of TC temperature, so repeatedly, occur that vibration fluctuated occurs indoor fan rotating speed.
Summary of the invention
The object of the invention is to consider the problems referred to above and a kind of effective anti-cold wind be provided, improving user's comfortableness, reach fast heat, the control method of the comfortable air conditioner air-out temperature that heats object.
Technical scheme of the present invention is: the control method of air conditioner air-out temperature of the present invention, air-conditioner is provided with the different anti-cold air temperature TE that prevents air outlet blowing cold air, anti-cold air temperature TE and design temperature TS meet following functional relation TE=B+f (TS), in the time that design temperature TS raises, anti-cold air temperature TE raises, in the time that design temperature TS reduces, anti-cold air temperature TE reduces, simultaneously, according to different anti-cold air temperature TE, air-conditioner is in heating process, indoor fan can move setting speed WS, gentle breeze rotating speed W0, the rotating speed W that is linear change that shuts down and determine according to indoor heat converter temperature between WS and W0.
The default following anti-cold air temperature value TE of above-mentioned air-conditioner, is respectively:
Temperature rise stage indoor fan setting speed WS startup value: TE1=B1+f (TS);
Temperature rise stage indoor fan rotating speed is linear change startup value: TE2=B2+f (TS);
Temperature rise stage indoor gentle breeze rotating speed W0 startup value: TE3=B3+f (TS);
Temperature-fall period indoor fan rotating speed is linear change startup value: TE4=B4+f (TS);
The indoor gentle breeze rotating speed of temperature-fall period W0 startup value: TE5=B5+f (TS);
Temperature-fall period indoor fan temperature value: the TE6=B6+f (TS) that quits work;
Described B1, B2, B3, B4, B5, B6 is the constant of setting according to type, and, in the time of TS >=24 DEG C, f (TS)=24, in the time of 24 DEG C of TS <, f (TS)=TS.
The rotating speed W that is linear change determining according to indoor heat converter temperature between above-mentioned WS and W0, according to judging indoor heat converter temperature rise or decline, is respectively:
Temperature rise stage indoor fan rotating speed is the actual motion value of linear change: W1=(TC-TE2) ÷ (TE1-TE2) × (WS-W0)+W0=(TC-B2-f (TS)) ÷ (B1-B2) × (WS-W0)+W0;
Temperature-fall period indoor fan rotating speed is the actual motion value of linear change: W2=(TC-TE5) ÷ (TE4-TE5) × (WS-W0)+W0=(TC-B5-f (TS)) ÷ (B4-B5) × (WS-W0)+W0.
Above-mentioned B constant is set to: the scope of B1 > B4 and B1 and B4 is 9 ~ 21 DEG C; The scope of B2 > B5 and B2 and B5 is-4 ~ 6 DEG C, and B6 scope is-8 ~-4 DEG C; B2 >=B3, B5 >=B6.
Above-mentioned air-conditioner unlatching heats or defrost finishes the starting stage of heating up, indoor fan stops, in the time that indoor heat converter temperature T C reaches the anti-cold air temperature TE3 of setting, indoor fan becomes gentle breeze W0 from halted state, indoor heat converter temperature continues to rise, in the time that indoor heat converter TC temperature reaches the anti-cold air temperature TE2 of setting, indoor fan rotating speed starts according to W1=(TC-TE2) ÷ (TE1-TE2) × (WS-W0)+W0=(TC-B2-f (TS)) ÷ (B1-B2) × (WS-W0)+W0 operation, indoor heat converter temperature T C continues to rise, in the time that indoor heat converter temperature T C temperature reaches the anti-cold air temperature TE1 of setting, indoor fan moves according to setting speed,
While causing indoor heat converter temperature T C to decline because of off-premises station frosting or other reasons, in the time that indoor heat converter temperature T C reaches anti-cold air temperature TE4, indoor fan rotating speed is according to W2=(TC-TE5) ÷ (TE4-TE5) × (WS-W0)+W0=(TC-B5-f (TS)) ÷ (B4-B5) × (WS-W0)+W0 operation, when indoor heat converter temperature continues to decline, when indoor heat converter temperature T C reaches TE5, indoor fan transfers gentle breeze W0 operation to, continue cooling, in the time that indoor heat converter temperature T C reaches TE6, indoor fan is out of service.
Above-mentioned W1=(TC-TE2) ÷ (TE1-TE2) × (WS-W0)+W0=(TC-B2-f (TS)) ÷ (B1-B2) × (WS-W0)+W0 and W2=(TC-TE5) ÷ (TE4-TE5) × (WS-W0)+W0=(TC-B5-f (TS)) ÷ (B4-B5) × (WS-W0)+W0 result of calculation only retain whole 10 multiples.
The present invention is no longer a concrete fixed value owing to adopting anti-cold air temperature, but according to the function of design temperature TS, the function that anti-cold air temperature TE is design temperature TS: TE=B+f (TS).Simultaneously, entering in anti-cold wind control, indoor fan rotating speed is no longer also concrete fixing rotating speed, but rise or definite value that declines according to indoor heat converter temperature T C, ascent stage, W1=(TC-TE2) ÷ (TE1-TE2) × (WS-W0)+W0, decline stage W2=(TC-TE5) ÷ (TE4-TE5) × (WS-W0)+W0, rotating speed is linear change with indoor heat converter temperature T C.Because anti-cold air temperature is the number of being determined by design temperature, and be the value linear with indoor heat converter temperature T C entering indoor rotating speed after anti-cold wind, entering after anti-cold wind, do not have the sudden change of rotating speed like this, effectively improve the heating capacity under low temperature.The present invention is a kind of control control method of air conditioner air-out temperature easily.
