The edge of 32 offers the arcuate socket 33 for accommodating fixing described blade 31.The VFC heat sink arrangement of the present invention can lead to
Cross VFC tail-end blower fan coiled radiator, make system run and be automatically adjusted according to actual load size, reduce useless power consumption,
Solve the high energy consumption problem of household central air conditioner；Blade on the tangential impeller of the present invention uses S type structure actual, compares tradition
Semicircular arc blade, its air blast effect is more preferable, and noise is low, and can reduce the strength of vortex within tangential impeller.
In order to improve the blowing efficiency of blade further and drop low wind noise, described blade 31 radially outward from described solid
The arc length (A section arc) of price fixing 32 part is more than the arc length (B section arc) being positioned at described fixed disk 32 axis projection.Described blade 31
The ratio in arc length and the arc length being positioned at described fixed disk 32 axis projection radially outward from described fixed disk 32 part
For 1.5-2.5.
For the ease of installing blade, and strengthen the mounting stability of blade 31, two sections of arcs of described blade 31 (A section in Fig. 3
The intersection of arc and B section arc) point of contact be positioned on the circumference of described fixed disk 32.
The flow direction of the wind in order to optimize and then within tangential impeller 3, improves distinguished and admirable stationarity, described blade 31 in footpath
Part surface to the axis projection being positioned at described fixed disk 32 is coated with one layer of layer of silica gel 34.
The rated power 22W of described direct current variable frequency motor 2, it is the highest transfers 1600 turns to.Described tangential impeller 3 is aluminium alloy
Tangential impeller 3, a diameter of 80mm of described tangential impeller 3, a length of 630mm, described blade 31 is provided with 30 (can also root
Border gauge size selects the quantity of blade factually).Described combined guided mechanism 4 includes impeller leading truck, impeller bracing frame, wind
Wheel base plate, wind wheel top board.Described surface cooler 6 is that 3 row 8 hole copper tubes wear hydrophilic aluminium foil, up and down 2 water collecting and diversifying devices of welding, water route
Flow process is 3 to enter 3 and go out, hydrophilic aluminium foil sheet spacing 1.8mm.Described shell 1 is faced left right side by wind dish front panel, wind dish rear board, wind
Plate composition closed cavity in addition to return wind transom.
The control logic of the double temperature double control frequency-variable controller of the present invention is:
1. heating mode: design temperature ST, room temperature RT, air-conditioner water outlet temperature WT, Δ T=ST-RT, when WT < 25 DEG C,
Blowing-out dish, when WT 25 DEG C and ST-RT > DEG C rotation speed of fan and air-conditioner water outlet temperature are the linear relationship shown in Fig. 4, regulates at this
During, if in 30 minutes, water temperature does not rise to 35 DEG C, and wind speed reduces a grade, if at next 30 minutes
The most not rising 35 DEG C, wind speed reduces a grade again, the like.If rising 35 a water temperature in 30 minutes
DEG C, it is returned to original wind speed scale successively.
Linear relationship below | ST-RT | 2 rotation speed of fan with Δ T, in the range of the maximum wind velocity (R1) that water temperature is given,
The temperature difference and maximum wind velocity R1 linear relationship is utilized to regulate wind speed, during thermostatic control, Automatic-searching constant temperature rotating speed, as far as possible
Accomplish constant temperature, not stall.
If ST+0.5 > RT > ST-0.5, RT-ST ＞ 2, rotation speed of fan 200 turns, after 30min, still RT-ST ＞ 2 blower fan stops
Rotate.
2, refrigeration mode: ST < RT, indoor fan rotating speed and leaving water temperature, according to the linear relationship described in Fig. 5, are adjusted at this
During joint, if in 30 minutes, water temperature does not drop to 10 DEG C, and wind speed reduces a grade, if at next 30 points
The most not declining 10 DEG C in clock, wind speed reduces a grade again, the like.If at a water temperature drop 10 in 30 minutes
DEG C, it is returned to original wind speed scale successively.
Linear relationship below | ST-RT | 2 rotation speed of fan with Δ T.
In the range of the maximum wind velocity (R1) that water temperature is given, the temperature difference is utilized to regulate wind speed with maximum wind velocity R1 linear relationship,
During thermostatic control, Automatic-searching constant temperature rotating speed, accomplish constant temperature, not stall as far as possible.
Work as ST+0.5 > RT > ST-0.5, ST-RT ＞ 2, rotation speed of fan 200 turns, still ST-RT ＞ 2 after 30min, blower fan stops
Spline is moved.
3, blower fan manual mode: under blower fan manual mode: low speed: rotation speed of fan 400 turns, middling speed 800 turns, at a high speed 1200
Turn.Blower fan is no longer according to lower water temperature.
Technical scheme is simply explained in detail by above-mentioned detailed description of the invention, the present invention the most only office
Be limited to above-described embodiment, it will be understood by those skilled in the art that every according to above-mentioned principle and spirit on the basis of the present invention
Improve, substitute, all should be within protection scope of the present invention.
