【 Weak current College 】 air conditioner not cold non-fault analysis 】

Air conditioner use certain phenomena during surface seems to be down, but it is not a fault. Therefore, when the cooling effects of unsatisfactory situation, the first exclusion of the following seven reasons. Don't put the normal misjudgment is failure, eager to have it repaired, spent odds; there are also some phenomenon is due to improper operation and cited, and users should be able to adjust, not liable to failure.
Common to these phenomena in the following areas: (1) external ambient temperature is high, the room personnel and more, air conditioner full load, export the wind blowing out is cool, but room temperature drop and couldn't, this is not a fault. When the ambient temperature is higher than 33 ℃, the outside world into heat increase, increased air conditioner refrigeration load; if the room numbers, for example 20 sqm room 2500W cooling capacity, if the room has a sitting still for 10 people.　　Each person's line about heat to 120W 10 personal total is a 1200W, to spend half the cooling capacity of air conditioners, air conditioners of cooling capacity is not enough, the room temperature drops down. This is normal, it cannot be said that air conditioner not available.　　(2) power supply voltage is too low, the air conditioner is not easy to start, start and shut down or the fuse blow. This is not a fault, just check the power supply is a power grid voltage is too low, users should install the power supply voltage regulator, voltage 220V, reached normal use the air conditioner.　　(3) in the strong cold, room temperature drops down, out of the outlet air flow rate, this is air filters ash limit, blocked the air circulation, causing built-in refrigerating capacity cannot be mobile air out in a timely manner, resulting in insufficient cooling capacity.　　This is not a fault, just remove the filter to clean, can be back to normal. (4) air conditioning open in strong cold stalls, fan with high-speed operation, vibration and noise is large, this is normal. (5) air conditioning thermostat regulation incorrectly, without exerting the maximum functionality of refrigeration, leading to a room cooled down, adjust the thermostat to resolve.　　(6) heat pump air conditioner in the colder winter cooling thermal effects are not ideal, this is normal. For no automatic defrosting of heat pump air conditioner that uses minimum ambient temperature is 5 ° c, zero is lower than the temperature would not heating or effect is very poor, this is because the external heat exchanger accumulate Frost blocked air flow, not from the outside world for the sake of inhaled heat; for automatic defrosting of heat pump air conditioner that uses minimum ambient temperature is-5 ° c lower than the temperature of the heating cannot be effective. (7) air conditioner installation location is not good, can also cause indoor temperature refrigerating effect of uneven or poor, to resize the air conditioner installation location.
