In the cold and windy winter, how to prevent cold has become a key issue. However, we often open the summer air conditioning, many people also know that in addition to cooling and heating functions. On the heating problems are often some people have some doubts Today, we analyze the seven issues, hoping to help everyone.
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 heats up, the air conditioner absorbs the outdoor air heat through the outdoor unit heat exchanger, and then transfers the heat to the indoor through the heat exchanger of the indoor unit. Meanwhile, when heating, the outdoor unit heat exchanger is used as the evaporator Use, 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 transfer effect, resulting in poor overall heating air-conditioning, or even can not heat. Therefore need to start the air conditioning auxiliary electric heating function, or the use of other heating equipment.
3, 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 ℃;
4, 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.
5, why the air conditioning has been switched on, 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.
6, why the indoor unit is not running water when heating, outdoor machine 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.
7, 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 conditions, the hot air will not come out until after 3-5 minutes. The specific situation depends on the outdoor environment at the time.
After the above question and answer way, I believe on the issue of heating air conditioning also have a more detailed understanding of the daily use of home appliances, or operating under the understanding of the situation will be more comfortable to use more.
