Embodiment Construction

[0010] The failure operation control method of the DC inverter air conditioner of the present invention will be further described below.

[0011] The faulty operation control method of the DC inverter air conditioner of the present invention comprises the following specific steps:

[0012] (1) Classify the faults and protections of existing DC inverter air conditioners;

[0013] (2) To determine whether the air conditioning unit is faulty:

[0014] The air-conditioning unit starts to run, and fault judgment is made during the operation: if there is no fault, the air-conditioning unit continues to run; if the air-conditioning unit fails, it will stop according to the fault level or enter the corresponding operating mode with faults.

[0015] 2. The fault operation control method of DC inverter air conditioner according to claim 1, characterized in that: classify the faults and protections of existing DC inverter air conditioners, and set them from level 1 to level 24, a total ...

Abstract

The invention discloses a fault operation control method of a DC (direct current) convertible frequency air conditioner, which comprises the following concrete steps of: (1) carrying out classification on a fault and protection of the existing DC convertible frequency air conditioner; and (2) judging whether an air conditioning unit has the fault or not, i.e. starting and operating the air conditioning unit, carrying out fault judgment in the operating process, continuously operating the air conditioning unit if the air conditioning unit has no fault, and carrying out shutdown or entering a corresponding fault operation mode according to the grade of the fault if the air conditioning unit has the fault. In the control method, the air conditioning unit operates with the fault on the premise of no malignant fault and the fault problem is solved after work.

Description

technical field [0001] The invention relates to the technical field of DC frequency conversion air conditioners, in particular to a method for controlling faulty operation of DC frequency conversion air conditioners. Background technique [0002] In order to ensure the normal and reliable operation of the air-conditioning unit, especially the effective protection of the air-conditioning system, the DC inverter air-conditioning system adds many protection measures to the control software of the air-conditioning unit, such as: protection against excessive exhaust temperature and protection against low suction temperature , high voltage protection, low voltage protection, overcurrent protection, overvoltage / undervoltage protection, module protection, antifreeze protection, outdoor coil temperature protection, outdoor ambient temperature protection, indoor coil temperature protection, indoor ambient temperature protection, compressor Start failure protection, drive module abnorm...
