Household air conditioner: Can we add snow seeds to air conditioner in winter?

Snow species can be added to household air conditioners in winter, and whether snow species are added or not has nothing to do with the season.

How long it takes to add fluoride to air conditioners (that is, snow seeds) is directly related to the installation of air conditioners. If installed, you don't need to add it once every five or six years.

Adding refrigerant to air conditioning and refrigeration system requires higher technical level of operators. If the refrigerant is added improperly, it is easy to cause air to mix into the refrigeration system pipeline, thus causing new abnormal faults of the air conditioner. Therefore, it is recommended to find a professional to add snow seeds.

Fluorination method (that is, adding snow seeds)

At normal temperature and pressure, R4 10A is a chlorine-free fluorinated alkyl non-boiling mixed refrigerant, which is a colorless gas and stored in a steel cylinder. Combined with the characteristics of R4 10a, the application practice of R4 10a instead of HCFC22 in room air conditioning system is carried out, and theoretical analysis and system matching are carried out.

The experimental results show that under the same conditions, compared with HCFC-22, the heat transfer coefficient increases and the flow resistance decreases. Through system optimization and matching design, the performance (COP) has been greatly improved, reaching the A-class energy efficiency level in the European market.

Generally speaking, we can use low-pressure filling and static filling.

1. Turn on the air conditioner for refrigeration, and then start filling at low pressure. When filling to 0.35 ~ 0.55 MPa, observe the refrigeration effect of the air conditioner. If possible, the measured high pressure should not exceed 2.2Mpa.

2. When the air conditioner stops running, add fluorine from the fluorine adding place. Applicable when the system pressure reaches 0.8 ~ 0.9 MPa.

Leave the air conditioner on for 30 minutes and check it carefully.

4. The correct filling method, you must take your time when filling. After adding a little, let the air conditioner run for about 10 minutes, and then measure the pressure and current. If it is really unavoidable, add it a few times. It can't be based on the pressure and current at that time. In that case, it may be too much.

When fluoride is added in winter, the coil of the four-way valve can be disconnected, or the indoor temperature sensor can be cooled manually to start refrigeration. Sometimes the air conditioner can operate in dehumidification mode, and the temperature requirement is not very high.
