It will officially enter the central heating season tomorrow. Strong cold air will follow in the ensuing days. Although most citizens rely on heating, due to the renovation of the heating system, there is still a lot of residential heating to be delayed till this year So at the end of the month, air conditioners will become the mainstay of heating in this most difficult season, how to use the air conditioner to warm up and how to save more energy?
Relatively higher efficiency air conditioning heating lower prices
Compared with the heating, air-conditioning heating efficiency is relatively high.According to experts, said the 1.5-heating and cooling air-conditioning, for example, do not open the electric auxiliary heating conditions, the general heating power is 1KW, heating 3000KW. That consumes 1KW of electricity, can produce 3KW of heat, which is much higher than the heating efficiency of heating, so many people consider whether the use of air conditioning heating or heating in winter heating.On this issue, you can first count an account:
If a home by 2 air-conditioning calculation, 24 hours a day open, the entire heating season by 4 months .A winter down need to spend more money, air-conditioning heating rated power of a 2000w, a 1200w, total 3200w, one hour electricity The amount of 3.2 degrees, once the current average electricity Xi'an is 0.52 yuan, one hour electricity 1.66 yuan. So, 24 hours a day electricity 39.84 yuan, 1195.2 yuan a month, a heating season, the total electricity cost is 4780.8 yuan.
Of course, the above 4780.8 yuan for all-weather heating, in fact, we can not count the hours of work 10 hours, at home for 14 hours do not need some boot time, the second 2-3 months, sometimes a sudden increase in temperature , A lot of time do not need air conditioning, air conditioning at the same time with the frequency conversion function, not all work at rated power.
In this case, let's re-calculate: deduct 40% from work, non-14-hour continuous boot deduction of 20%, 2-March deduction of 20%, frequency deduction of 20%, our actual utilization rate: 60% × 80% × 80 % × 80% = 30.7%. According to 30% of the calculation, the annual electricity bill should be: 4780.8 × 30% = 1434 yuan. Even if the above calculation is not very accurate, get an integer, calculated according to 2000 yuan, Much lower.
Air conditioning and easy to cause air-dry
Ventilation and humidification essential
Of course, the above cost comparison is not to encourage everyone to use air-conditioning heating, although the air-conditioning thermal efficiency, the price is cheaper than heating, but air-conditioning heating also has disadvantages .Experts said air conditioning heating biggest disadvantage is uneven temperature and easily lead to indoor drying In addition, consumers feel the deepest is that once the air conditioner is turned off, the indoor temperature drops quickly, making it difficult to adapt.
Therefore, in the winter if you decide to use air-conditioning heating, there are several tips to use must pay attention to the first is to ensure that the air-conditioning set temperature heating conditions, the lower the set temperature the better.This will be more energy-efficient, in addition, Because hot air is lighter than cold air, hot air is easy to float above space, so when using wall-mounted air conditioners it is best to lower the air outlet angle and to save electricity.
In addition, do not switch the air conditioning frequently, just turn on the air conditioning, the wind speed should be set to high wind speed, you can speed up the exchange of hot and cold, until close to the set temperature, the wind speed can be set to low wind speed The switch air conditioner, it will consume more power, but also a certain loss on the compressor.
Of course, the most important thing is to timely humidification and ventilation: As the air conditioning heating, especially electric auxiliary heating air conditioning heating, likely to cause indoor air is too dry, so winter air conditioning heating humidifier humidification is very necessary. Effect, the use of air conditioning and heating are generally closed doors and windows, with thick curtains to isolate the cold window of the window, so the best heating effect, but due to air-conditioned room does not flow of air, there are many harmful bacteria easy Survival in such an environment must be ventilated.
