Vehicle air conditioner and its low power consumption standby method and circuit

Abstract

The invention discloses a vehicle-mounted air conditioner as well as a low power consumption standby method and circuit thereof. The vehicle-mounted air conditioner comprises an indoor unit standby circuit and a power supply circuit used for providing standby voltage to the indoor unit standby circuit to control the standby of an indoor unit, wherein the power supply circuit comprises a boosting circuit used for performing boosting adjustment on an input power supply at a preset switching frequency. The low power consumption standby method of the vehicle-mounted air conditioner comprises the following steps that a standby mode of the vehicle-mounted air conditioner is monitored; and when the vehicle-mounted air conditioner enters the standby mode, the boosting circuit is controlled to stopworking after working for first preset time according to the preset switching frequency, and restart to work after intermittently resting for second preset time. According to the vehicle-mounted airconditioner as well as the low power consumption standby method and circuit thereof, the standby power consumption of the vehicle-mounted air conditioner is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted air conditioners, in particular to a low-power standby method for a vehicle-mounted air conditioner, a low-power standby circuit for a vehicle-mounted air conditioner, and a vehicle-mounted air conditioner. Background technique [0002] Car air conditioners, also known as parking air conditioners, are generally used in large transport vehicles. Large transport vehicles often need to park and wait on the side of the road. Due to the short waiting time, the car air conditioner is generally not turned off. At this time, in order to save energy, the car owner will control the indoor unit. Enter standby mode. [0003] At present, in order for the indoor unit of the car air conditioner to be in standby mode normally, the booster must work normally for a long time. The price paid for the long-term normal operation of the booster is high standby power consumption. After the vehicle is parked for a...
