As we all know, for air conditioning, freon is an indispensable refrigerant, is the key to cold air in summer, but do you know, in fact, air conditioning heating also needs freon condensation and heat release principle, in air conditioning heating effect is not good, is it caused by lack of fluorine? With us to have a look at air conditioning heating is not a lack of fluorine?
Is air conditioning heating bad lack of fluorine
Generally speaking, the heating effect of air conditioning is not good, partly because the air filter collects too much dust, and the internal and external machine vents are blocked by foreign bodies. The role of the filter is to absorb the dust in the air, if the accumulation of dust is too much and not timely cleaning will block the air flow, resulting in a reduction of the air outlet, resulting in the internal heat can not be brought out of the flowing air in time, resulting in insufficient heat, this is not a fault, belongs to the maintenance of air conditioning, just take off the air filter cleaning regularly, can be restored to normal.
In addition, when the ambient temperature is too low, the energy efficiency ratio of air conditioning will also be reduced, and the heating effect is not ideal, which is also a normal phenomenon. Therefore, experts suggest that the best choice of air conditioning electric heating type. It’s a failure. Fluorine deficiency is one of them. It can be seen that fluorine deficiency is indeed one of the reasons for air conditioning heating is not good, but it is not the only factor. We should carefully identify where the root of the problem is, and then find professional maintenance personnel door-to-door repair.
The main performance of air conditioning fluorine deficiency
1. The system pressure is low, and the normal value is between 1.8-2.2mpa in winter.
2, the current is low, normal value should be close to the rated current of air conditioning (rated power divided by voltage);
3. The surface temperature of the indoor heat exchanger is very low, and the temperature difference between the outlet and the return air outlet is less than 15℃.
4. The upper part of the outdoor heat exchanger is frosted, and the rest is frost-free.
Precautions for adding fluorine to air conditioning
1, air conditioning fluoride how much is reasonable
This is probably the air conditioning users are most concerned about the topic, the market is now mixed, there is a hanging air conditioning fluoride spent nearly two hundred yuan things happen, in fact, this is a low price to move the machine or low price installation to users of the trap. Take 1.5P wall-mounted air conditioning in summer as an example. In the case of no fluorine, it is reasonable to charge about 80 yuan because of vacuum treatment.
2. How long does fluoridation take
Air conditioning fluoridation special pipe is connected, an air conditioning fluoridation only needs about 5-10 minutes, winter fluoridation time will be slightly longer.
About air conditioning heating is not good fluorine is introduced here, I hope to help you.
