The 'cold spring' came and recently there has been a noticeable drop in temperature in most parts of the country. In the early morning of March 17, the Beijing area had ushered in a long absence of snow, the weather was still cold, and the northern regions have extended the heating period, such as Beijing 2017 The heating period for residents of ~2018 was extended by five days and ended at 24:00 on March 20.
March 17, 2018 Beijing welcomes first snow
Seeing that the heating in the house has become 'cool' and the weather is still cold, how can we comfortably spend this period of cold spell? Fortunately, there is it - air conditioning, this artifact that used to save countless lives in the summer! Air conditioning is one of the greatest inventions in the history of mankind. Cooling in the summer, heating in the winter, and creating the most comfortable living environment. How can we use the air-conditioner to make heating more energy-efficient? Today, the author will support everyone's measures to ensure that Air conditioning is energy-saving and comfortable.
● Air conditioning heating principle
To make air-conditioning more energy-efficient, we must first understand its working principle. Most of the air-conditioners on the market today are used for cooling and heating. They can either be cooled or heated. In fact, the principle of air-conditioning cooling/heating is very simple, using liquefaction ( From the gaseous state to the liquid state, heat is released; when vaporizing (from liquid to gas), the physical phenomenon of heat absorption is required. The specific operating principle can be referred to the following diagram.
Air conditioning working principle
During air-conditioning and heating, the refrigerant (gaseous) is pressurized by the compressor to become high-temperature and high-pressure gas, enters the heat exchanger of the indoor unit, condenses and liquefies into a liquid, and simultaneously releases a large amount of heat, heats the exchanger, and blows the hot air through the blower. , In order to increase the indoor temperature, the refrigerant (liquid) continues to flow and is decompressed by the throttling device and enters the outdoor unit's exchanger. The evaporative vaporization becomes gaseous state. The refrigerant that has become gaseous enters the compressor again and repeats the process. Cycle, to achieve continuous heating air conditioning.
◆ Extended: What is the ghost of electric auxiliary heating?
When the air conditioner is heating, it converts the heat energy of the outdoor air into the indoor, but if the outdoor air temperature is too low, the air conditioning and heating effect is poor. Therefore, many air conditioners use the auxiliary electric heating, that is, the inside machine adds an electric heating tube to assist heating. In order to achieve the ideal heating effect.
Electric auxiliary heating is more expensive
The design of electric auxiliary heating is actually to increase the heating effect of air conditioning in cold weather. The temperature of the air conditioner with charged auxiliary heat rises faster, and the temperature of the air conditioner without auxiliary heat increases slightly. In addition, the electric auxiliary heating of air conditioning You can switch it by yourself. The remote control has function buttons, usually with the word “auxiliary heat”. However, note that turning on electric auxiliary heating will inevitably increase the energy consumption of the air conditioner. Everyone should use their own temperature actual conditions.
1, set the temperature not too high
First of all, do not try to warm up and set too high a temperature. It is recommended to set the temperature below 24°C. The human body feels more comfortable, and the air conditioning also has better energy-saving effect. In order to be able to heat more quickly, the author teaches you a small trick. : When the air conditioner is turned on, it is possible to set a slightly higher temperature than expected (for example, 28°C) to allow the indoor to quickly reach the desired temperature. After about 15 minutes of running, the temperature is comfortable and the temperature is lowered (24°C and below), and the reading is changed to low. Air volume or energy saving mode can greatly reduce the power consumption of air conditioning operation.
PS. The power consumption of the air conditioner has a direct relationship with the set temperature. When the heating is performed, the temperature is set to 1~2°C. The human body cannot feel the small temperature difference in the room, but the air conditioner can save more than 10%.
2, blowing under warm air
Everybody knows the common sense of the physics: The ratio of cold air is significant, and the proportion of hot air is light. Therefore, the air-conditioning heating allows the air outlet to be downward, that is, the hot air is blown down! In doing so, the hot air that is blown out will naturally rise, thus warming the room as a whole. , Thermal efficiency and comfort will be greatly increased, reducing power consumption.
3, do not frequently switch air conditioners within a short time
The start-up of the air conditioner is also accompanied by the synchronous start of the outdoor unit compressor, which requires a large amount of current each time the compressor is started. Frequent switching air conditioners in a short period of time also mean that the compressor is also repeatedly started, resulting in additional grounding. The power consumption, and may also cause damage to the compressor, affect the service life. Therefore, it is recommended to avoid frequent switching air conditioners within a short time (1 to 2 hours), in other words, it is completely unnecessary to turn off the air conditioner in a short time.
4, regular cleaning filter and cooling fins
When the air conditioner is heating, it is easier to generate floating dust in the room. Various pollutants accumulate on the air filter screen, affecting the heating efficiency, and the warm internal environment is also prone to bacterial growth. This causes secondary pollution and threatens the health of the body. Therefore, regular cleaning of air conditioners is required. Machine filter and cooling fins.
Clean air conditioner internal filter
The air conditioner internal filter can be directly taken out, placed in tap water, washed, and then dried and replaced. The cleaning of internal evaporator fins requires a special cleaning agent, and operation according to the instructions is not complicated Regular cleaning of the filter and fins can effectively reduce the power consumption, but also can effectively prevent bacteria from producing odors, and protect respiratory health.
Air conditioning heating room drying Use humidifier to adjust indoor humidity
5, increase indoor humidity available humidifier
This point must be understood by everyone: Use of air conditioning heating will make the indoor air becomes very dry! In order to control the indoor humidity in the comfort zone, care of respiratory health, there are ways to humidify, such as a humidifier installed. Note: Do not directly add tap water to the humidifier! It is not only easy to produce water and alkali damage to the machine but also not conducive to respiratory health. It is best to add purified water, or boil the tap water until it is cool and then add it. In addition, place a pot in the room. Water or regular rubbing, can also play a very good humidification effect.
Write last
Here, the air conditioner power saving tips shared for everyone are drawing to a close. The emergence of air conditioners has indeed completely improved people's home environment, so that the temperature is appropriate, making life more comfortable, but the over-temperature comfort environment will also allow The body's own resilience, resistance and various regulatory mechanisms slowly degenerate. Therefore, the author suggests: In appropriate circumstances, it is still necessary to minimize the use of air-conditioning, more outdoor sports, more physical exercise, and fresh air for Healthy fuel!
