Problems solved by technology

When the driver or motor of a fan fails, it is often necessary to replace the entire fan, which is expensive and inconvenient to repair
[0003] The air-conditioning system of a bus is generally equipped with multiple evaporating fans and condensing fans. The cost of the two types of fans accounts for a large proportion of the cost of the entire bus air-conditioning fan drive system. The one-to-one driving method increases the manufacturing of the bus air-conditioning fan drive system. cost and maintenance

Abstract

The invention discloses a drive system and a drive method for a bus air-conditioning fan. The drive system for the bus air-conditioning fan comprises a plurality of evaporation fans, a plurality of condensing fans and a control circuit, wherein the control circuit is mounted in an electric control room of a bus air-conditioning system; the control circuit comprises an evaporation fan driver and a condensing fan driver; input ends of the evaporation fan driver and the condensing fan driver are connected with a power supply; the output end of the evaporation fan driver is connected with a motor of the evaporation fans; and the output end of the condensing fan drivers is connected with a motor of the condensing fans. The drive system can effectively reduce manufacturing cost and maintenance cost of the bus air-conditioning fan drive system.

Description

[technical field] [0001] The invention relates to a bus air-conditioning system, in particular to a driving system and a driving method for a bus air-conditioning fan. [Background technique] [0002] The driver of the DC fan is a variable voltage driver, which can obtain the required fan speed by changing the control voltage (0-10V) of the fan. The evaporating fan or condensing fan of the air conditioning system mainly includes the following three parts: the motor part, the driving part and the fan body. At present, in the air conditioning system of the bus, the three parts of the fan are integrated to form a fan assembly. In this case, one driver can only drive one fan, which belongs to one-to-one driving. When the driver or motor of a fan fails, it is often necessary to replace the entire fan, which is expensive and inconvenient to repair. [0003] The air-conditioning system of a bus is generally equipped with multiple evaporating fans and condensing fans. The cost of ...
