Method for controlling operation of air conditioner in mute mode

Abstract

The invention provides a method for controlling operation of an air conditioner in a mute mode. In the method, the air conditioner can automatically enter a mute control mode according to the change of outdoor environment temperatures, so that automatic control is realized. The method comprises the following steps of: calculating the time when the air conditioner starts to operate in the mute mode; during refrigeration, controlling the relation of the common target evaporation temperature during operation of an air conditioning system in an unmute mode and a new target evaporation temperature; and during heating, controlling the relation of the common target condensation temperature during operation of the air conditioning system in the unmute mode and a new target condensation temperature. By the method, the frequency and the noise of the air conditioning system are reduced, and the air conditioning system operates in the mute mode; and the change of the environment temperature is scientifically calculated, the air conditioning system is intelligently controlled, an outdoor unit is automatically controlled, and operation such as dial-up setting and the like is not required, so requirements of customers on the effect of the air conditioner can be met, requirements of the customers on low noise can also met, and system failures can be avoided.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a method for controlling silent operation of an air conditioner in a central air conditioning system. Background technique [0002] At present, the demand of customers for central air-conditioning systems is increasing. At the same time, the common problems of the outdoor units of central air-conditioning such as loud noise are becoming more and more prominent. In order to deal with such problems, the majority of air-conditioning manufacturers have added silent operation control to the air-conditioning control. to meet customer needs. [0003] The traditional silent operation mode is mainly controlled by the following two methods: ① Professionals set the dial code, and enter the silent operation mode directly after dialing the code or after a few hours, and cannot exit, because the central air conditioner is an invisible installation , The outdoor unit is ge...

Problems solved by technology

[0003] The traditional silent operation mode is mainly controlled by the following two methods: ① Professionals set the dial code, and enter the silent operation mode directly after dialing the code or after a few hours, and cannot exit, because the central air conditioner is an invisible installation , The outdoor unit is generally hung outside the wall, and the indoor unit is installed in the ceiling. If the dialing method is used, the customer cannot operate it by himself and needs the help of professional technicians. The operability is poor. After the dialing is completed, it cannot be automatically restored, which will affect the system. At the same time, after the code dialing is completed, the dialing code must be set again if you want to restore the system, which is time-consuming and laborious; ②Enter and exit through the indoor controller button, and after entering the silent operation, limit the maximum operating frequency and speed of the outdoor unit to achieve low speed. Noise is realized by pressing the buttons on the controller, which is more convenient for customers, but it is more arbitrary. Customers can request the system to enter silent operation at any time. It may be realized by pressing buttons at noon in hot weather, but the load is heavy at noon, and the outdoor unit runs at low speed. It cannot meet the requirements of use, and at the same time, the outdoor fan runs at a low speed, resulting in poor heat dissipation of the system. The system will fluctuate back and forth under the dual requirements of ensuring the effect and ensuring the noise, resulting in system failure, and the user needs to manually cancel the silent operation. Once forgotten, The system may always operate under the condition of silent operation; at the same time, the central air conditioner generally uses one outdoor unit to connect multiple indoor units. If one user requires silent operation, but the other user does not, the system will still enter silent operation. As a result, the system effect is reduced at the same time, which may cause complaints from other users

[0004] To sum up, the two existing control methods for the silent operation of the air conditioner have the following disadvantages and deficiencies respectively; for the dial setting, the operability is poor and the degree of freedom is insufficient; Meet individual needs
