1, the colder the weather, the worse the heating effect?
A: It is mainly because the cooler the weather is, the lower the outdoor temperature is. The more difficult it is to absorb the air heat from the outdoor air environment, resulting in a relatively poor heating effect.
2, why -5 degrees below, it is recommended to switch to other equipment heating?
A: In winter, when the air conditioner is heating up, the air conditioner absorbs the heat of the outdoor air through the outdoor unit heat exchanger (ie, the condenser) and then delivers the heat to the room through the heat exchanger (ie, evaporator) of the indoor unit. Meanwhile, during heating , Outdoor unit heat exchanger is used as an evaporator, when the outdoor temperature is below -5 degrees, the condenser and outdoor air heat transfer temperature difference will be close to 0. Therefore, there is no heat exchange effect, resulting in the overall air-conditioning system Poor thermal effect, or even can not heat.Therefore, need to start the air conditioning auxiliary electric heating function, or the use of other heating equipment.
3, air conditioner why frost?
A: When heating in winter, the outdoor air passing through the condenser condenses on the fins and frosses due to the evaporation temperature of the outdoor unit heat exchanger (ie, the condenser) below zero, which may affect the performance of the condenser Heat transfer area and the air flow, thus affecting the heating effect of air conditioning.Therefore, in order to ensure that the air conditioning heating effect must be defrosting work.
4, how to determine whether an air conditioning heating is normal?
A: air conditioner heating and cooling test standard: boot 15-20 minutes later, at a distance of 10-20mm from the indoor air outlet with a thermometer test head temperature measurement, cooling inlet and outlet temperature difference should not be less than 10 ℃, in the heating state Under (heat pump air conditioning) inlet and outlet temperature difference should not be less than 15 ℃, electric auxiliary air-conditioning inlet and outlet air temperature difference should not be less than 23 ℃;
5, the outlet temperature level, why can not represent the machine is there any problem?
A: The air conditioner air outlet temperature level can not be used to determine and measure an air conditioner is normal standard Air conditioning normal judgment and measure the standard is mainly to see the air conditioning in the heating, the engine inlet and outlet temperature difference to determine As long as the temperature difference between the inlet and the outlet reaches the standard, we can determine that there is no problem with the air conditioner.
There are many other factors that form the temperature of the air outlet to jointly decide, one is the matching problem of the machine and the environment, the other is the temperature of the air in the room itself, and other external influences, etc. The air conditioner itself has a certain power and the air volume is also certain, Judge the normal machine mainly by their ability to ascend through the air temperature to determine, is the temperature difference between import and export to determine! If the inlet temperature is high, then the outlet temperature is high, whereas the temperature is low, the outlet The temperature will be lower accordingly. Is a soaring reason .So that the level of tuyere temperature, can not be used to assess and judge whether a machine is heating and cooling normal signs.
6, why the air conditioning has been booted to a certain extent why the temperature is difficult to rise?
A: The room temperature is low, so air-conditioning heating to enhance the room temperature is more obvious.With the room temperature increases, the indoor temperature and outdoor temperature difference increases, then the indoor heat transfer to the outdoor will be more, so the indoor temperature Rise will slow down.When the temperature difference reaches a certain level, the heat generated by the air conditioner is just delivered to the outside and neutralized, so to this extent, the temperature will not rise further.
7, why air-conditioning in the heating, will often hear the clap clap sound?
A: Most of the appearance of air conditioner indoor unit is made of plastic, when the heating (the same is also the case when cooling), plastic parts of the thermal expansion and contraction, the sound generated by the shell slight deformation, is a normal situation, etc. This situation will gradually disappear after the plastic parts are shaped.
8, why sometimes air conditioning boot smell?
A: (1) The taste of the newly renovated room is inhaled in the air conditioner; (2) Other sources of odor in the room are sucked into the air conditioner; (3) The newly installed machine has a slight plastic taste in a short time and will soon disappear; (4) Air conditioner air filter has not been cleaned for a long time.
9, Why is the indoor unit when heating water, outdoor unit water?
A: The opposite of heating and cooling, the work of the indoor unit and the work of the outdoor unit swap a bit.Cooling indoor unit is flowing water, heating is just the opposite, that is, outdoor unit produces water, but the water is not generated to form a condensate Along the condenser fins flow down, but the formation of frost (frost is mainly generated by the ambient temperature is too cold) attached to the fins, to a certain time to defrost melt before flow down.
10, why sometimes indoor air suddenly suddenly big small suddenly?
A: There are two important situations that occur in this situation, one situation may be user air filter dirty, uneven wind, and then another case is the air conditioning heating, air-conditioned room to ensure the supply air temperature, indoor Motor automatically adjust the fan speed, resulting in a high wind for a while will be low-wind. Under normal circumstances, when this problem occurs, allowing the first check the filter.
11, why heating, the indoor unit occasionally have 'rushing' sound of water?
A: This is the process of air conditioning operation, the refrigerant state changes constantly, there is liquid into a gas, in a gaseous state into a liquid. This normal physical imagination in the refrigerant at a certain speed, due to a certain resistance , Ashes produce a certain flow of 'rushing' sound, is a normal phenomenon, especially in the dead of night, especially evident.
12, why the heat when the boot will take a while before the heat out?
A: The main is our human-machine design, designed to prevent cold wind function. Heating, the heat accumulation and upgrading of a process, if there is wind on the boot, then it is cold out in the winter itself is very cold In the case of a sudden cold wind blows at startup, people are at risk of getting cold. Generally, under normal circumstances, the hot air will not come out until after 3-5 minutes. The specific situation depends on the outdoor environment at the time.
13, in the heating, why after the air conditioning is still blowing off?
A: The main is our air-conditioning design has redundant thermal function, the machine in use, a shutdown, if the fan also immediately stop working, then there will be part of the heat inside the machine, which affects the use of heat, and secondly due to heat Gathered in the indoor unit, easy to cause deformation of some plastic parts.
14, electric auxiliary heating start redness is normal?
A: Under normal circumstances, electric auxiliary heating tube will not be red, but when the voltage is too high, or low-wind operation, or filter clogged red appears when the phenomenon can check the voltage or clean the filter or set high wind operation , If it is local red electric heating tube within the heating wire winding uneven, resulting in local heat is too high. Can explain with the user red electric heating tube is a normal phenomenon.
15, why the temperature did not reach the set temperature to stop working, what is the reason?
A: Because the hot air is light, it accumulates in the upper part of the room, and the temperature detected by the indoor temperature probe is higher than the temperature in the lower half of the room. Therefore, the temperature setting of the remote control must be slightly lower than the room temperature. Remote control set the temperature higher than the ideal ambient temperature 4 ~ 6 ℃.
16, the winter heating, outdoor machine heat, leakage is how is it?
A: This is the air conditioner defrosting, is a normal phenomenon.
Because the heat pump air conditioner heating in winter, outdoor heat exchanger through the need to absorb heat from outside, work outside the heat exchanger surface temperature is very low, gradually frosting too much, it will affect the heating effect, so the air conditioner With defrost function, controlled by the air conditioner computer board automatically, the defrost time is about 10 minutes, defrosting outdoor unit has dissolved water flow.
17, heating, why the indoor unit to stop blowing for a period of time, a few minutes and automatically open?
A: This is the air conditioner in the defrost, when the air conditioner is running for some time, the outdoor condenser will end thick frost, if you do not melt the frost, it will directly affect the air conditioner heating effect, so when the air conditioner is running 40 After reaching the defrost condition for more than minutes, the air conditioner will defrost and the indoor unit will stop working during the defrosting process.
18, air conditioner boot half an hour why the room temperature is not up to the desired effect?
(1) heating this season to see if the air conditioner remote control electric heating function is turned on, the remote control has a 'dry auxiliary heat' button, open the air conditioner remote control will display 'auxiliary heat', this time auxiliary heat to open, Enhance the heating effect;
(2) The air conditioner can be adjusted to 'super' file, air conditioner air speed and compressor operating frequency increase, to further ensure the heating effect;
(3) air-conditioning heating guide vanes will send air down, to ensure that the hot air are blowing down, if the air-conditioning guide vane is not down, then adjust the air conditioning 'up and down the wind' to ensure the deflector down, the effect Better
(4) Check the air conditioning heating air volume, if the wind is small, it is recommended that customers clean the filter, the filter will also affect the blockage of air conditioning heating effect.
