Air conditioning principle is not complicated, but rather on the use of the installation.
Refrigerating effect not satisfied? yourself to get.
Air conditioner use certain phenomena during surface seems to be down, but it is not a fault.
When the cooling effects of unsatisfactory conditions, should first excluded the following seven reasons.
Outdoor temperature too high
(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 20m2 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 1200W, to spend half the cooling capacity of air conditioners, air conditioners of cooling capacity is not enough, the room temperature drops down.
Voltage low
(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 reason, in the case of a power supply voltage is too low, the user should install the power supply voltage regulator, voltage 220V, reached normal use the air conditioner.
Ash multiple filters
(3) in the strong cold, room temperature drops down, out of the outlet air flow rate, this is the air filter too much ash deposits, 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.
Strong windshield also causes noise
(4) in the strong cold gear most fan to the high-speed operation, vibration and noise is large, this is normal.
Improper adjustment of the temperature controller
(5) the thermostat regulation incorrectly, without exerting the maximum functionality of refrigeration, leading to a room cooled down, adjust the thermostat to resolve.
The weather is too cold or not
(6) heat pump air conditioner in the colder winter heating effects of unsatisfactory, 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.
Poor installation location
(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.
Use the questions and answers
Noise
Q: window type air conditioner use noise is what causes?
A: (1) window type air conditioner is a one-piece unit.
Compressor operation noise will pass through to the Interior, the increase of noise. While the split of the compressor in outdoor, no influence on the Interior.
(2) window type air conditioner room side air circulation with head higher centrifugal fans, it's the noise score of tubular fan style.
(3) window type air conditioner is fixed to the window frame or window sill, easy vibration generated noise.
When it finds this situation, you should increase the support, reduced machine vibration.
Ventilation
Q: camion unable to ventilate the room?
A: use the split air conditioner room should be a half-day or next day window once, every 15-20 minutes for the outdoor fresh air into the room to improve indoor air quality.
Because the split type air conditioners and window type air conditioner, it cannot be installed ventilation of valve, indoor unit run within a closed in layers, as time increases, becoming polluted indoor air. Breath carbon dioxide emission increase the concentration. Breath of oxygen consumed Interior, a long time makes indoor oxygen decline, to a certain degree can make people feel dizzy and does not apply, it is often called a "air conditioning sickness."
Dehumidification
Q: there is a special feature of the air conditioner in DH in what weather location in dehumidify?
A: air conditioner set special dehumidification function is damp weather drying rooms available, so this kind of weather, you can open the dehumidifier operating mode, would lower the room temperature.
Dehumidification in two ways: a by computer intermittent control compressor start stop, make the cold evaporator condensate water vapor in the air, the air volume is small, so it does not lower the room temperature, cooling load main absorption condensate of latent heat of condensation; the other is in the air conditioner was specifically set by-pass refrigerant solenoid valve, solenoid valve open when the desiccant, reduced to the amount of refrigerant in the evaporator, the evaporator Interleave of condensed water vapour is mainly used to play the role, but basic desiccant does not lower the room temperature.
Doors and Windows
Question: air conditioned room for doors and Windows have any requirements?
A: in order to improve cooling effect, the air conditioning room doors and Windows, ceiling and floor, etc., must be maximum seal.
Select air blowing cold air flow better to blow the door because this air flow resistance from the door and hot air.
Comfort temperature
Q: the comfortable air conditioned room temperature and humidity?
Answer: human perception threshold temperature of 33 ° c, less than 33 ° c with cold feeling, more than 33 ° c hot.
When the temperature ° c, relative humidity of 50%, air velocity of 0 · 15/second (m/s), the human body in an optimal thermal equilibrium, feel most comfortable.
For the comfort of our country's situation as: humidity in summer is the indoor temperature 26-29 ° c, relative humidity of 40%-60%; winter indoor temperature 16-21 ° c,
On humidity 30%-50%.
