Air conditioner and control method for air conditioner

Abstract

The invention provides an air conditioner and a control method for the air conditioner. The air conditioner at least has: an outdoor unit equipped with a compressor, an indoor unit equipped with a blower, a heat exchanger, and a room temperature sensor, and a control unit for controlling the compressor and the blower. The device is characterized in that the indoor unit is also equipped with a heater, which is controlled by the control device, and the air conditioner also has a temperature setting device for setting the temperature. When the heating is running, and when the indoor temperature detected by the room temperature sensor When the temperature reaches a certain temperature higher than the set temperature, the control device performs the first linkage control operation to stop the compressor and start the heater.

Description

technical field [0001] The present invention relates to an air conditioner and a control method for the air conditioner, in particular to slowing down the rate of room temperature drop by means of auxiliary heating by a heater, avoiding too frequent starting and stopping of the compressor, prolonging the service life of the compressor, and improving the user's comfort Air conditioners and air conditioner control methods. Background technique [0002] The indoor unit of existing fixed-frequency air conditioner is made up of heat exchanger, air blower, air blower motor, and the casing that accommodates the above components. In addition, the operation volume is controlled according to the detected room temperature through indoor sensors and temperature setting. [0003] For example, when the heating is running, such as Figure 5 As shown, after the air conditioner is started, the compressor and the blower are started at the same time. When the indoor temperature rises to the "...

AI Technical Summary

Problems solved by technology

[0005] First of all, after the compressor stops, since there is no heat delivered to the air-conditioned space, the indoor temperature drops rapidly under the influence of the external temperature and the air exchange rate, which affects the user's ambient temperature comfort

[0006] In addition, when the room temperature drops sharply and drops below the set temperature, the compressor will start again. When such a cycle is repeated, the compressor will start and stop frequently, which will easily cause the compressor to be overloaded and reduce its service life.
