Refrigerant R410A air conditioning refrigerant method and key points of maintenance

add refrigerant refrigerant r410a air conditioning method and maintenance points you to understand? Don't understand it doesn't matter, here small make up for everyone to do the introduction, let's get together and see it.

1, confirm the name of air conditioning refrigerant before operation, and then to the operation of the different refrigerant implementation, using R410A refrigerant must not use the refrigerant R410A refrigerant.

2. Be sure to check before add refrigerant funnelled to deal with again after funnelled add refrigerant, note: it is prohibited to use air or cold media crackdown leak detection.

3, R410A refrigerant is an analog azeotropic mixture refrigerant, when add refrigerant, ensure to add refrigerant liquid way.

4, R410A refrigerant leakage after add refrigerant has the following five kinds of methods, details are as follows:

method one:

remote control into the rated cooling mode, the refrigeration compressor opens the mode of case: the remote set temperature of 17 ℃; The remote control set high winds of the wind; 10 seconds press strong 6 consecutive ( Or more than six times) , after 10 seconds to 10 seconds (long tone of the buzzer rang The music of the buzzer ringing up) , enter the rated refrigerating test run. Compressor operation frequency fixed rated test frequency, indoor and outdoor fan wind speed fixed to the rated wind speed test.

method 2:

enter the rated refrigerating mode with the remote control with beautiful small plate test, check the exhaust temperature, exhaust temperature in 75 - 80 ℃ is more appropriate.

method 3:

in open test small plate, cooling mode using the beauty view to temperature and indoor temperature tube temperature, add refrigerant, T = T tube + back ( 1 - 3) ℃

method 4:

enter the rated refrigerating mode with the remote control, wind turbine within 20 minutes or more, observe evaporator for homogeneous condensation state, back to the trachea homogeneous condensation.

note: the above methods are in the external environment temperature above 0 degrees to complete. 5:

method

under the external environment temperature is below freezing, must adopt the way of quantitative add refrigerant add refrigerant. Ambient temperature is lower than - in the outside world 10 try to persuade the customer not to use air conditioning, air conditioning maintenance as far as possible before the rise of temperature of the spring season for repair.

the above introduction about the R410A refrigerant to the over here, hope to be able to bring you some help, if you have a demand on refrigerant R410A, welcome consultation discussion with us, we wholeheartedly at your service.
