Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] An intelligent control method for low-temperature operation of an air conditioner, comprising the following steps:

[0035] Step A: After the main control unit of the air conditioner receives the cooling instruction, control the indoor temperature detection device to detect the indoor temperature, and the outdoor temperature detection device to detect the outdoor ambient temperature;

[0036] Step B: The main control unit of the air conditioner corrects the detected indoor temperature according to the indoor temperature, the outdoor ambient temperature and the set temperature to obtain the corrected indoor temperature;

[0037] Step C: The main contr...

Abstract

The invention discloses an intelligent control method for low-temperature operation of an air conditioner, and particularly relates to a method for intelligently controlling low-temperature operationof an air conditioner and the air conditioner. The method for intelligently controlling low-temperature operation of the air conditioner comprises the following steps that A, after a master control unit of the air conditioner receives a refrigerating command, an indoor temperature detection device is controlled to detect the indoor temperature, and an outdoor temperature detection device is controlled to detect the outdoor environment temperature; B, the master control unit of the air conditioner corrects the detected indoor temperature according to the indoor temperature, the outdoor environment temperature and the set temperature to obtain the indoor corrected temperature; and C, the master control unit of the air conditioner controls the operation frequency of a compressor according tothe indoor corrected temperature. Meanwhile, the air conditioner is provided. Through correction to the indoor temperature, the operation frequency of the compressor is controlled according to the corrected indoor temperature, under the condition that the air conditioner is in low-temperature refrigerating operation and it is guaranteed that the pipe temperature meets refrigerating, the frequencyof the compressor is in low-frequency operation, and the air conditioner can operate stably.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to an intelligent control method for low-temperature operation of an air conditioner. Background technique [0002] Existing air conditioners operate at a high frequency during low-temperature refrigeration operation, resulting in too low outlet air temperature, often resulting in antifreeze protection. [0003] The frequency control of common inverter air conditioners is mainly controlled according to the temperature sensor of the indoor environment and the set temperature. If the set temperature is different, the operating frequency range will be different. For example: when the indoor temperature is 20°C, the operating frequency of the compressor at 18°C ​​is set to 40HZ, and the operating frequency of the compressor at 16°C may be 60HZ. [0004] When the outdoor temperature is low and the indoor temperature is not high (for example: the outer ring is...
