Embodiment Construction

[0053] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054] The invention provides a control method of an air conditioner, referring to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the control method of the air conditioner of the present invention.

[0055] In this embodiment, the control method of the air conditioner includes the following steps:

[0056] Step S10, obtaining the current temperature of the evaporator coil;

[0057] In this embodiment, a temperature sensor is provided in advance at the evaporator coil of the indoor unit of the air conditioner, and the temperature sensor is used to detect the temperature of the evaporator coil in real time. During the cooling process of the air conditioner, the current temperature T of the evaporator coil is obtained through the temperature sensor n .

[0058] Step S20, calculating the a...

Abstract

The invention discloses a method for controlling an air conditioner. The method for controlling the air conditioner comprises the steps of obtaining the current temperature of an evaporator coil pipe, calculating the temperature difference between the obtained current temperature of the evaporator coil pipe and a preset reference temperature, and adjusting the current operation frequency of a compressor according to the temperature difference to enable the temperature difference to be within a preset temperature interval with the minimum temperature being larger than or equal to zero. The invention further discloses a device for controlling the air conditioner. By means of the method and device, the refrigeration effect of the air conditioner is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method and device for an air conditioner. Background technique [0002] During the cooling process of the air conditioner, in order to reduce the indoor ambient temperature as soon as possible, the operating frequency of the compressor of the outdoor unit is usually increased. At this time, the temperature of the evaporator of the indoor unit is likely to be too low. frost. In the prior art, a temperature sensor is generally installed on the evaporator, and when the temperature sensor detects that the temperature of the evaporator is lower than zero, the compressor is controlled to stop running to perform a defrosting operation. During the defrosting process, since the compressor stops running, the cooling effect of the air conditioner is greatly affected. Contents of the invention [0003] The main purpose of the present invention is to provide a control m...
