In order to solve the problems of the technologies described above, technical scheme provided by the utility model is: a kind of automatic defrosting air-conditioning comprises compressor, the first evaporimeter, the second evaporimeter, the first stop valve, the second stop valve, the 3rd stop valve, the 4th stop valve, first row wind turbine, second row wind turbine and condenser; Described the first evaporimeter is with after the second evaporimeter is in parallel, then by pipeline, circulates and be connected successively with condenser with compressor; Described the first stop valve and the second stop valve are separately positioned on the first evaporimeter and the second evaporimeter and pipeline that compressor is connected; Described the 3rd stop valve and the 4th stop valve are separately positioned on the first evaporimeter and the second evaporimeter and pipeline that condenser is connected; Described the first evaporimeter and the second evaporimeter are arranged side by side; Described first row wind turbine and second row wind turbine are arranged between the first evaporimeter and the second evaporimeter back-to-back, and the outlet air surface of first row wind turbine is over against the first evaporimeter, and the outlet air surface of second row wind turbine is over against the second evaporimeter.
A kind of automatic defrosting air-conditioning, also comprise the leaf assembly that keeps out the wind that the fan blade that can stop first row wind turbine and second row wind turbine rotates.
After having adopted technique scheme, the utlity model has following beneficial effect: (1) the utility model, by two evaporimeters and two motor exhausts are set, is realized in the situation that continuously heating is removed the frosting on evaporimeter, do not take away indoor hot gas, effectively improve heating efficiency.
(2) the leaf assembly that keeps out the wind of the present utility model can stop the fan blade of first row wind turbine and second row wind turbine to rotate, while preventing first row wind turbine or the operation of second row wind turbine, wind turns round through the fan blade of out-of-date drive second row wind turbine or first row wind turbine from second row wind turbine or first row wind turbine, affects intake.
The accompanying drawing explanation
For content of the present utility model more easily is expressly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is:
Compressor 1, the first evaporimeter 2, the second evaporimeter 3, the first stop valve 4, the second stop valve 5, the 3rd stop valve 6, the 4th stop valve 7, first row wind turbine 8, second row wind turbine 9, condenser 10, leaf assembly 11 keeps out the wind.
The specific embodiment
(embodiment 1)
See Fig. 1, the automatic defrosting air-conditioning of the present embodiment, comprise compressor 1, the first evaporimeter 2, the second evaporimeter 3, the first stop valve 4, the second stop valve 5, the 3rd stop valve 6, the 4th stop valve 7, first row wind turbine 8, second row wind turbine 9, condenser 10 and the leaf assembly 11 that keeps out the wind.
The first evaporimeter 2 is with after the second evaporimeter 3 is in parallel, then by pipeline, circulates and be connected successively with condenser 10 with compressor 1.The first stop valve 4 and the second stop valve 5 are separately positioned on the first evaporimeter 2 and the second evaporimeter 3 and pipeline that compressor 1 is connected.The 3rd stop valve 6 and the 4th stop valve 7 are separately positioned on the first evaporimeter 2 and the second evaporimeter 3 and pipeline that condenser 10 is connected.The first evaporimeter 2 and the second evaporimeter 3 are arranged side by side.First row wind turbine 8 and second row wind turbine 9 are arranged between the first evaporimeter 2 and the second evaporimeter 3 back-to-back, and the outlet air surface of first row wind turbine 8 is over against the first evaporimeter 2, and the outlet air surface of second row wind turbine 9 is over against the second evaporimeter 3.The leaf assembly 11 that keeps out the wind can stop the fan blade of first row wind turbine 8 and second row wind turbine 9 to rotate.
Under normal operation (wind direction in Fig. 1 is for from right to left), the first stop valve 4 and the 3rd stop valve 6 are opened, the second stop valve 5 and the 4th stop valve 7 are closed, second row wind turbine 9 is in running status, first row wind turbine 8 is run-stopping status, and the leaf assembly 11 that keeps out the wind stops the fan blade of first row wind turbine 8 to rotate, while preventing 9 operation of second row wind turbine, wind, from the fan blade running of first row wind turbine 8 through out-of-date drive first row wind turbine 8, affects intake.In the case, air-conditioning is in normal heating operation state.
When environment temperature lower, and machine runs to the regular hour, after causing frosting on the first evaporimeter 2 and reaching certain degree, the ability that the machine operation heats can be very low, now stop compressor 1 and 9 operations of second row wind turbine, after 1 minute, close the first stop valve 4 and the 3rd stop valve 6, and open the second stop valve 5 and the 4th stop valve 7.The leaf assembly 11 that keeps out the wind discharges the fan blade of first row wind turbine 8, and stops the fan blade of second row wind turbine 9 to rotate, and while preventing 8 operation of first row wind turbine, wind, from the fan blade running of first row wind turbine 8 through out-of-date drive second row wind turbine 9, affects intake.After 2 minutes, start compressor 1(to meet protections in 3 minutes of compressor 1) and first row wind turbine 8(Fig. 1 in wind direction for from right to left).Now machine proceeds to heat running, enters simultaneously the defrost state of removing the frost on the first evaporimeter 2.
Under this defrost state, the frost on the first evaporimeter 2 not only can melt with environment temperature is higher, and can under the effect of first row wind turbine 8 blowings, accelerate to soften, and the frost on very fast the first evaporimeter 2 just can soften complete.
Otherwise the frost on the second evaporimeter 3 acquires a certain degree, and the frost on evaporimeter 1 is softening when complete, open the first stop valve 4 and the 3rd stop valve 6, and close the second stop valve 5 and the 4th stop valve 7, first row wind turbine 8 out of service, start second row wind turbine 9.The leaf assembly 11 that keeps out the wind stops the fan blade of first row wind turbine 8 to rotate.Machine enters the defrost state of removing the frost on the second evaporimeter 3.
So iterative cycles, when defrosting, can reach compressor 1 and start the stop frequency minimizing, extend the life-span of compressor, and do not need to change by cross valve the flow direction of refrigerant, in the situation that do not take away indoor hot gas, realize the purpose of heating and defrosting, effectively improved heating efficiency.
The automatic defrosting air-conditioning of the present embodiment is for split air conditioner and central air conditioning successful.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
