Abstract
The utility model discloses a condensing fan for a bus air conditioner. The condensing fan comprises a motor, fan blades and a fan frame body, wherein the motor is fixedly connected with the fan frame body and is coaxially connected and matched with the fan blades; and the condensing fan also comprises an automatic wind speed regulation system which is connected and matched with the motor. Compared with the prior art, the condensing fan has the advantages that the pressure of the fan can be reasonably controlled by the automatic wind speed regulation system, then the service life of the fan is prolonged, and the safe and stable operation of a refrigeration system is ensured; and energy consumption is reduced, the fan is low-carbon and environment-friendly, meets the requirements of the national environmental protection policy and has a good economic effect.
Description
Technical field
The utility model relates to a kind of condensation fan, belongs to the Fan Equipment technical field, refers in particular to a kind of bus idle call condensation fan.
Background technique
For the air conditioner refrigerating unit that adopts air cooled condenser, condensing pressure can change along with the variation of ambient temperature.Condensing pressure raises, and the exhaust pressure that makes refrigeration compressor is raise, and pressure ratio increases, thereby causes the gas transmission coefficient of compressor to reduce, and power consumption increases, and coefficient of refrigeration descends, and the rate of fault of compressor increases, and the safety reliability of operation reduces.For the air conditioner refrigerating unit of whole year operation, the higher phenomenon of condensing pressure mainly appears at summer, but generally the phenomenon of air conditioner refrigerating unit standard design operating mode can not occur being higher than for a long time; And when outdoor environment temperature is lower than the standard design operating mode, particularly during winter operation, condensing pressure phenomenon on the low side will appear, cause expansion valve before and after pressure reduction diminish, cause fluid supply capacity not enough, vaporizer lacks liquid, system's refrigerating capacity descends significantly.Present existing condensation pressure control method mainly contains through air quantity valve regulation cooling air delivery, the operating number that changes condensation fan and condensation fan variable frequency regulating speed control etc.The air quantity valve regulation is to keep blower fan to decide the rotating speed operation, is prone to the waste electric energy, shortens the life-span of blower fan; Change the occasion that condensation fan operation platform number is applicable to many typhoons machine, can cause that also the blower fan start and stop are frequent, the phenomenon that the condensing pressure fluctuation is big.
