Embodiment Construction
[0055] Air-conditioning units are sometimes used in the application scenario of installing super-long connecting pipes. At this time, the ex-factory liquid volume of the air-conditioning unit cannot meet the liquid volume after the super-long connecting pipes are installed, and the liquid volume needs to be replenished from the external refrigerant tank during after-sales installation. In addition, during the normal operation of the unit, the existing refrigerant circulation system lacks a good automatic adjustment mechanism for the amount of refrigerant, so that there is a deviation between the amount of refrigerant in the air-conditioning unit and the optimal amount of refrigerant, resulting in the air-conditioning unit not being able to operate in the best state. The operation affects the cooling or heating effect of the air conditioner.
[0056] In view of the above problems, the present invention proposes a method and device for adjusting the amount of refrigerant during t...

The present invention provides a control method, device and air conditioner for automatically replenishing the amount of liquid added in cooling mode. The method includes: when the air conditioning system is turned on in cooling mode, it is judged whether the air conditioning system is powered on for the first time, and if so, it enters the debugging stage, and if not The air-conditioning system operates in the set cooling mode; after the air-conditioning system runs for the first preset time, it continuously detects and records the real-time temperature of the exhaust gas, the real-time temperature of the outdoor environment, and the real-time temperature of the indoor coil; , The real-time temperature of the indoor coil, the preset exhaust temperature and the initial temperature of the indoor coil control the air supply pipeline or liquid storage pipeline of the air conditioning system to communicate with the main refrigerant circulation system pipeline. The invention realizes automatic adjustment of the amount of refrigerant in the air-conditioning system by controlling the air supply pipeline or the liquid storage pipeline to be connected to the main refrigerant circulation system pipeline, without the need for professionals to perform liquid addition operations, avoiding the leakage risk of refrigerant charging, and improving air conditioning. cooling effect of the system.
Description
technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a control method and device for automatically supplementing liquid addition in cooling mode, and an air conditioner. Background technique [0002] The factory liquid volume of air-conditioning units is generally filled with refrigerant according to the requirements of the national standard pipe length. The national standard pipe length is generally 5m or 7.5m. In order to ensure the operation effect and reliability of the refrigerant, the after-sales installer needs to pump the vacuum from the external refrigerant tank to add liquid when installing the super-long connecting pipe on site. [0003] However, this method of adding liquid has the following disadvantages: (1) For flammable and explosive refrigerants such as R290 and R32 refrigerants, there are safety risks in the process of charging refrigerants, and fire protection equipment is required for protection...
