Air conditioning system and air conditioner outdoor unit standby control method and device

Abstract

The invention discloses an air conditioning system and air conditioner outdoor unit standby control method and device. The air conditioner outdoor unit control method comprises the following steps: acquiring outdoor environment temperature, oil temperature at bottom of a compressor and oil temperature at bottom of an oil separator; acquiring set temperature values, wherein the set temperature values include temperature upper limit value and / or temperature lower limit value; respectively comparing the amplitude relations between the outdoor environment temperature, the oil temperature at bottom of a compressor and the oil temperature at bottom of an oil separator and the set temperature values; and determining whether an electric heating device enters a working state according to the amplitude relations. According to the invention, whether the electric heating device needs to be started to enter a working state in a current working environment is judged according to the relations between the outdoor environment temperature, the oil temperature at bottom of a compressor and the oil temperature at bottom of an oil separator and the set temperature values, so as to ensure the start reliability of the compressor. Therefore, according to the technical scheme, unnecessary electric auxiliary heating time can be avoided, and further standby power consumption of the unit is reduced.

Description

technical field [0001] The invention relates to the field of air-conditioning control, in particular to an air-conditioning system and a standby control method and device for an air-conditioning outdoor unit. Background technique [0002] In the air conditioning system in the prior art, when the unit is shut down, in order to ensure the reliability of the compressor startup, the electric heating device for electric auxiliary heating will determine whether to power on and work according to the external ambient temperature. However, in the prior art, when the electric heating device is controlled to enter the working state, the electric auxiliary heater will be in the working state for a long time, which leads to the problem of excessive standby power consumption of the unit. Contents of the invention [0003] Embodiments of the present invention provide an air conditioning system and its outdoor unit standby control method and device to solve the problem in the prior art th...
