Detailed Product Description: | Air conditioning and heating in winter, the outdoor unit heat exchanger temperature is very low, it will have after the frost phenomenon met with ambient air, frosting is too thick, it will affect the efficiency of air conditioning, so the air conditioning will automatically defrost treatment. Defrosting is actually a four-way switching valve, changing the direction of flow of freon (air conditioning cooling state but in the indoor unit fan is not working, otherwise blowing cold air), the outdoor unit heat exchanger heat to melt the frost off some time in 2- about 3 minutes. Winter air conditioning does not defrost reasons: 1, the ambient temperature is too low not defrost: Winter ambient temperature is too low, causing the air conditioning, then defrost difficult, due to outdoor temperatures below 0 degrees, the impact of air conditioning and heating effects. The lower the outdoor temperature, the worse the effect of air conditioning and heating, which is actually not enough heating capacity. 2, the air conditioning system is not enough to defrost heat: air conditioning and heating normal, but for an area smaller than the use of air conditioning and heating, air-conditioned room area, such as the 50 machines (2) second-hand air conditioning, using 35 machines (1.5 ), at room temperature, of course do not increase, ie rated heating capacity is not enough. There may not be open auxiliary heating, less a part of the heating capacity. 3, air filter is clogged: air conditioning and heating normal, but for a long time due to indoor air conditioner filter does not remove dust, resulting in clogged with dust filters, resulting in reducing the amount of circulating air. Thus heat causes blowing enough, can not defrost. 4, the system leads to lack of fluoride defrost heat is not enough, and thus can not defrost. 5, the control board failure, air conditioning did not defrost. 6, defrost temperature sensor failure, resulting in air conditioning is not defrost. Gree air in heating mode boot, outside the machine is working properly. But open to the five minutes or so, Xuzhou brand used air conditioning prices, the screen appears a symbol HI, this is how the same thing? Gree display H1, which is conditioned defrost. Because hot air conditioning system inside and outside the machine becomes loose cold. When the heat reaches a certain temperature, the condenser outside the machine will defrost in the time that the fan down, fans outside the machine downtime, compressor, four-way reversing valve, change back to the outside of the outer thermal mechanism Machine frosting off (it will generate steam and water). Because different defrost time, so sometimes can not see the water. If your air conditioner more frequently, then defrost, Jinan Gree air-conditioning maintenance recommended that the filter inside the machine used to clean air-conditioning wholesale at Xuzhou, in addition to some of the high temperature can be adjusted too. Winter fluoride specific steps: 1, hit the heating mode, the fluorine at the table received a thick tube, find the cord pulled out after a four-way valve cooling state, will add fluoride used in plug-way valve in Xuzhou air conditioning installation, see heating the pressure and current (mainly to see the current, the current relatively quasi-), not enough to be pulled out so repeatedly rated far fluoridation process often feel under two tube temperatures, thin possession hot, thick tube a little hot on OK. 2, quantitative fluoride, according to the nameplate on the machine, how many kilograms of fluorine to increase the number of kilograms.
