Xuzhou Sheng Erda Refrigeration Electrical Services Ltd. 5. auxiliary heating function fails. If the electric auxiliary heating control circuit occurs or electric auxiliary heating equipment failure, does not work, at relatively low ambient temperatures, it will lead to lack of air conditioning heat capacity, even in the harsh environment of air conditioning and heating completely. 6. For an electric heat pump central air conditioning repair air conditioning acquisition, if there is high ambient temperature (above 5 ℃) heating normal and low ambient temperature (below 0 ℃) insufficient heating capacity or not heating, you should suspect electric auxiliary heating control circuit or electric auxiliary heating equipment failures appear old air conditioning maintenance, repairs should be focused on checking these two parts. Xuzhou 圣尔达 Refrigeration Electrical Services Limited air conditioning is not the cause of the three heating, heating and air conditioning division of environmental factors heat pump, heat pump and electric type and electric type three products under equal conditions of heating capacity, the first two power smaller than about half of the third, taking into account the power supply capacity and electricity costs, and now the family generally choose the first two categories and air conditioning (but should pay attention to their conditions of use apply only to the first two under the above -5 ℃ environment, apparently on the northern NA). Heat pump air conditioner, heating when the ambient temperature is too low, the air conditioning energy efficiency is also reduced, in the colder winter heating, air conditioning repair is not ideal, this is normal. For non-automatic defrost heat pump air conditioner, which uses the minimum ambient temperature is zero on 5 ℃, below this temperature is not heating or poorly, it is because the external heat exchanger frost blocking the air flow, heat can not be inhaled from the outside sake; for automatic defrost heat pump air conditioner, which uses the minimum ambient temperature is -5 ℃, below this temperature can not be effective heating.
