Problems solved by technology

In order to effectively heat, it is necessary to defrost frequently. When defrosting, the indoor heat exchanger is in cooling mode, which will consume a certain amount of indoor heat, and each defrosting time is longer.
Because of the frequent defrosting of traditional air conditioners, the indoor temperature fluctuates greatly, making people feel hot and cold, which seriously affects the health of users and the comfort of use.

Embodiment 1

[0026] see Figure 1-2 A kind of air-conditioning defrosting control method, comprises the following steps:

[0027] S1. In the heating mode of the air conditioner, the main control board of the air conditioner records in real time the coil temperature T1 of the outdoor heat exchanger collected by the outdoor heat exchanger sensor, the outdoor ambient temperature T2 collected by the outdoor ambient temperature sensor, and the continuous working time of the compressor H1 , the electric heating working time H2 in heating mode;

[0028] S2. If T2-T1≥X1°C recorded by the main control board of the air conditioner, and T1

[0029] S3. During the defrosting process, the main control board of the air conditioner controls the compressor to reduce the current speed to Z rps, and the main control board of the air conditioner synchronously controls the indoor fan to run at the breeze speed from the current speed;

[0030] S4. The main contro...

Embodiment 2

[0040] In order to achieve the above purpose, this embodiment also provides an air conditioner, which uses the above-mentioned air conditioner defrosting control method.

[0041] The air conditioner described in this embodiment has the same advantages as the above-mentioned air conditioner defrosting control method over the prior art, which will not be repeated here.

Abstract

According to the air conditioner defrosting control method, in the defrosting process, a four-way valve is reversed under the condition that a press is not stopped, and when a refrigeration mode is started indoors, an indoor fan operates at a low rotating speed, and electric heating is started at the same time. In this way, hot air can be continuously supplied to the indoor space through electric heating, the indoor fan operates at a low rotating speed, the air temperature can be prevented from being too low, it is guaranteed that the temperature of the electric heating surface is not too high, and the defrosting speed of the air conditioner is increased through circulation of hot air and heat radiation transmission of electric heating. After defrosting is finished and a heating mode is switched, electric heating is automatically started when an indoor fan starts to operate, and whether electric heating is operated or not is decided according to the set requirements of the air conditioner after high pressure is established indoors after operation is performed for a period of time. The invention further provides the air conditioner. Accessories and cost are not added on the basis of an original air conditioner, and the defrosting time is effectively shortened through reasonable control over the compressor, the indoor fan, the four-way valve, the outdoor fan and indoor electric heating.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting control method and an air conditioner. Background technique [0002] With the continuous improvement of people's living standards, the requirements for the use of air conditioners are also increasing. When the air conditioner is used outdoors in winter, it is very easy to frost, and the heating capacity will be seriously attenuated after frost. In order to heat effectively, it is necessary to defrost frequently. When defrosting, the indoor heat exchanger is in cooling mode, which will consume a certain amount of indoor heat, and each defrosting time is longer. Because of the frequent defrosting of traditional air conditioners, the indoor temperature fluctuates greatly, making people feel hot and cold, which seriously affects the health of users and the comfort of use. Contents of the invention [0003] In order to solve the above problems...
