Heating control method of air conditioner and air conditioner

Abstract

The invention provides a heating control method of an air conditioner and the air conditioner. The heating control method of the air conditioner comprises the steps that a heating signal of the air conditioner is obtained, and a compression refrigeration system of the air conditioner is controlled to be started in a heating mode; an electric heating signal of the air conditioner is obtained, and a heater in an air duct of the air conditioner is started; the indoor coil pipe temperature of the air conditioner is obtained, the operation state of a compression refrigeration system is adjusted according to the indoor coil pipe temperature, and the heating state of a heater is maintained; and after the indoor coil pipe temperature is larger than or equal to the first coil pipe temperature threshold value, the heater is turned off. According to the scheme, the heater is started as long as the electric heating signal is obtained; and once the heater is started, the heater is not easy to close according to the temperature of an indoor coil, the working state of the compression refrigeration system is adjusted, frequent starting and stopping of the heater of the air conditioner are avoided, and the service life of the heater is prolonged.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a heating control method of an air conditioner and the air conditioner. Background technique [0002] With the development of society and the continuous improvement of people's living standards, various air conditioning devices have become one of the indispensable electrical equipment in people's daily life. Various air conditioning devices can help people reach an adaptable temperature when the ambient temperature is too high or too low. Current air conditioning devices mainly include various types of air conditioners and fans. [0003] The "China Energy Efficiency Label" can intuitively indicate the energy efficiency level of home appliances, and the first-level energy efficiency means that the product's power saving has reached the international advanced level, and the energy consumption is the lowest. At present, the first-level energy-efficient air conditioners mai...

AI Technical Summary

Problems solved by technology

At present, the first-class energy-efficient air conditioners mainly use R32 refrigerant. Due to the increase in temperature and pressure of R32 refrigerant relative to R410A refrigerant, it often leads to a higher temperature in the air duct of the air conditioner, which in turn leads to a higher temperature of the auxiliary electric heating, resulting in hardware protection.

In short, the control of electric heating in the prior art has certain limitations, and it is easy to cause the electric heating hardware to be turned on frequently
