 In general, the cooling effect of air conditioning is not good, partly due to the air filter too much dust inside and outside vent blockage. The role of the filter is the absorption of air in the dust, If the accumulation of dust is too much and not timely cleaning will block the air circulation, resulting in reduced outlet of the air supply, which resulted in heat capacity can not be air flow in a timely manner to bring out, resulting in lack of heating capacity, this is not a malfunction, belonging to the maintenance of air conditioning, just on a regular basis to remove the air filter cleaning, you can return to normal. Be regarded as a failure, lack of fluoride to be regarded as one of them. At present, the friends are mostly using the heat pump or heat pump plus auxiliary electric heating and air-conditioning. These two works are air conditioning Freon evaporation absorbs heat from outdoor air when outdoor temperature is low, and the Freon evaporation temperature of the temperature difference is small, the effect of heat transfer along with variation, less hot air. Therefore, if the old model, a longer useful life, the degree of wear of the compressor when the outdoor temperature is below 0 ° C, air conditioning, heating effect is difficult to make people satisfied. In addition, if the installation of home air conditioning brass horn at the nut did not tighten or used to shift the machine can be considered as a lack of fluoride. In addition, the line control failure is more common. For example, if the outdoor unit does not work, most of the capacitance, temperature probe or motherboard failure.
