The refrigerant model used by Haier air conditioner 3P floor-standing is R4 10A.
Detailed introduction of R4 10A refrigerant:
Composition and characteristics:
R4 10A is an environment-friendly refrigerant, which consists of R32 and R 125 refrigerants.
It has high refrigeration effect and thermal conductivity, and is widely used in household and commercial air conditioning systems.
Air conditioning systems using R4 10A refrigerant usually have higher energy efficiency and lower environmental impact.
Fluorination process:
In the fluorination process, special fluorination tools, including fluorination tubes and pressure gauges, are needed to ensure accurate measurement and control of refrigerant charge and pressure.
The fluorination process should be operated by professional technicians or experienced maintenance personnel, and the general steps are as follows:
Make sure that the air conditioning system is turned off and disconnect the power supply.
Connect to the high-pressure port and low-pressure port of the air conditioning system with the fluoride adding tool.
According to the requirements and specifications of air conditioning system, refrigerant is injected into the system in an appropriate way.
After fluorination is completed, check and ensure that all connections are tightly sealed, and then close the fluorination tool.
Pressure requirements (based on the information in Ref. 4, but it should be noted that this information may be related to the specific model):
For three air conditioners, if a new type of environment-friendly refrigerant (such as R4 10A) is used, it is necessary to completely drain the refrigerant and refill it when the refrigerant is less than half, otherwise it will be replenished as much as possible.
When filling up, it usually reaches 8 pressure units (pa).
Precautions:
In order to ensure the correct and safe fluoridation operation, it is recommended to consult Haier after-sales service center or professional technicians, who can provide accurate guidance according to your specific air conditioning model and requirements.
