Air conditioning is a 'power-hungry'. Every summer, the number on the electricity bill doubles, the reason is related to it.
The refrigerator is afraid of heat, you put it in a hot and dry environment, it will help you to 'sell electricity' faster. There are many secrets on the Internet, what are the practical? July 17th, Jianghuai Morning News, Jianghuai network reporter interviewed several industry experts, please tell them, really reliable energy-saving methods.
Air conditioning, 'dehumidification mode' can save electricity, but not suitable for common use
A few days ago, Hangzhou Mao’s self-destructive air conditioner used the 'dehumidification mode', and the first-phase electricity fee was only 86 yuan. It was screened on WeChat. Is this power-saving method desirable?
'Half of the summer electricity load is used for refrigeration. We recommend that the air conditioner in the home be hit at 26-28 ° C. In fact, every 1 ° C high, the air conditioner can save 5-10% of electricity. ' Hefei Power Supply Company Control Center Deputy Director Wang Hongbo told reporters.
Then, like the uncle Mao of Hangzhou, is it feasible to use the 'dehumidification mode' to save electricity?
'Dehumidification mode as the name suggests, is for humidity, frequency is relatively low, power saving is affirmative. 'Hefei Haier air conditioning technology director Chen Xinhang told reporters, 'only, the dehumidification mode of the cooling rate is very slow, if you are anxious to cool, certainly still Preferred cooling mode. '
'Dehumidification mode starts at a very low speed. It liquefies the water vapor in the indoor air into condensate and discharges it outside, thus reducing the relative humidity. When the refrigerant in the evaporator evaporates, it absorbs a lot of heat. It also balances damp heat. That is to reduce some indoor temperature. 'Chen Xinhang said that the dehumidification mode runs for a long time, it is easy to make the room dry, reduce the comfort, and should not be used for too long.
'In addition, the air conditioner will be turned on after it has not been used for a while. Be sure to clean the filter. If there are conditions, you can also clean the evaporator and condenser. Too much dust will affect the cooling effect. 'Chen Xinhang It also said that it is not advisable to choose to shut down after a period of temperature and then turn it off, which will cause loss to the air conditioner.
The refrigerator is afraid of heat. It consumes more electricity in summer. It is best to leave some space for it.
'Summer, the refrigerator consumes more electricity, this is a normal phenomenon. 'The director of the Meiling Institute of Refrigeration, Shang Dianbo told reporters that the power consumption of the refrigerator is in accordance with national standards, and there is a power consumption dedicated to the user's reference, and this standard The value is equivalent to the ambient temperature of 25 ° C, the power consumption when the refrigerator door is not opened.
'The operation mode of the refrigerator is to discharge the heat inside through the heat dissipation mechanism. If the external temperature is high, it will definitely affect the heat dissipation. The load is higher and the energy consumption is relatively increased. ' Shang Dianbo said.
'Similarly, when we put the refrigerator, try not to let it close to the heat source, or in a room with a high temperature. Some users like to pile up things around the refrigerator, in fact, it is best to leave some room for ventilation. ' Dian Bo told reporters that if it is a direct-cooling refrigerator that uses frost in the freezer, it is best to turn off the power once in the summer to perform defrosting. 'Cream is a bad conductor of heat, affecting heat exchange efficiency, will increase energy consumption. Do a thorough defrost. '
In addition, the online circulation of the refrigerator door can save electricity, Shang Dianbo also expressed recognition. 'In summer, try to open the door as little as possible, and open the door as long as possible.'
Routers, set-top boxes are in 'sneak power consumption'
In addition to air conditioners, refrigerators and other visible power consumers, in fact, there are many household appliances that secretly help you spend electricity. 'Set-top boxes, routers are also consuming electricity, although it may be less than a day, but it also accumulates Many. If you are not at home during the day, you can turn it off. ' Gao Lei, a full-time engineer in the marketing department of Hefei Power Supply Company, said. 'Some high-power appliances that are not used, it is best to turn off the switch.' He suggested that electric water heaters are also recommended when not in use. Unplug the power supply. If you choose the peak and valley electricity price, you can heat it at night.
