As winter approaches, air conditioning and heating functions have become the focus of attention for many families. This article will combine the hot topics and common questions of users in the past 10 days on the Internet to provide you with a detailed analysis of the principles, usage skills and precautions of air conditioning and heating.
1. Data on popular air conditioning and heating topics on the entire network in the past 10 days
| Ranking | hot topics | Search volume trends | main focus |
|---|---|---|---|
| 1 | Reasons for poor heating effect of air conditioner | up 35% | Filter clean/insufficient refrigerant |
| 2 | Air conditioner vs heater power consumption comparison | up 28% | Energy efficiency ratio calculation |
| 3 | Is air conditioning available at minus 10℃? | up 22% | Low temperature start technology |
| 4 | Best temperature settings for air conditioning and heating | up 18% | 20℃ vs 26℃ controversy |
| 5 | New graphene air conditioner thermal efficiency | up 15% | Actual testing of new technologies |
2. Working principle of air conditioning and heating
Air conditioning and heating mainly useHeat pump principleImplementation:
1. The compressor compresses low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas.
2. The high-temperature gas releases heat through the indoor unit condenser
3. After the refrigerant is decompressed by the expansion valve, it absorbs external heat in the evaporator of the outdoor unit.
4. The whole process goes back and forth to realize the transfer of heat from outdoor to indoor.
3. 6 tips to improve heating efficiency
| Skills | How to operate | Improved effect |
|---|---|---|
| Set the temperature appropriately | Recommended temperature is 20-22°C. Each increase of 1°C increases energy consumption by 6%. | Energy saving 15-20% |
| Clean the filter regularly | Clean once a month, once a week for heavy use | Air volume increased by 30% |
| Use wind direction adjustment | The air outlet is angled downward at 45° | Thermal efficiency increased by 25% |
| With electric auxiliary heating | Start in severe cold weather (below -5℃) | Heating rate increases |
| Check door and window seals | Install sealing strip | Reduce heat loss |
| Avoid frequent switching | Keep running at low speed when going out for a short time | Extend compressor life |
4. Suggestions for use under different climate conditions
1.Yangtze River Basin (0-10℃): Ordinary heat pump air conditioners can meet the needs. It is recommended to set 20-22℃
2.Yellow River Basin (-10-0℃): Select the model with low-temperature start function and enable electric auxiliary heating
3.Northeastern region (below -25℃): It is recommended to use it with floor heating, and the air conditioner is only used for auxiliary heating.
5. Frequently Asked Questions
Q: Why does the outdoor air freeze when the air conditioner is heating?
A: This is a normal phenomenon. The air conditioner will automatically enter the defrost process. The air supply may stop for 5-10 minutes during defrost, which is a normal protection mechanism.
Q: What is the difference between variable frequency and fixed frequency air conditioning and heating?
A: Variable frequency air conditioners can automatically adjust power, have small temperature fluctuations (±0.5°C), and are about 30% more energy-saving than fixed frequency air conditioners.
Q: Is it normal for a new air conditioner to have a strange smell when heating it for the first time?
A: The plastic parts of the new machine may produce a slight odor when heated, which will disappear after 2-3 hours of operation. If it persists, please contact after-sales service.
6. Comparison of heating performance of mainstream brands in 2023
| brand | Low temperature starting ability | Energy efficiency ratio (COP) | Featured technology |
|---|---|---|---|
| Gree | -15℃ | 4.2 | Distributed air supply technology |
| Beautiful | -25℃ | 4.5 | Refrigerant ring cooling system |
| Haier | -20℃ | 4.3 | self-cleaning technology |
| Daikin | -15℃ | 4.8 | 3D airflow distribution |
7. Safe use reminder
1. Continuous operation should not exceed 8 hours. Ventilation is recommended during the operation.
2. The air outlet temperature can reach 50-60℃, avoid direct contact with children
3. If you smell something burnt, turn off the phone immediately and check the circuit.
4. When not in use in winter, it is recommended to run the power once a month to prevent the refrigeration oil from solidifying.
Through the above comprehensive analysis, I believe you have a deeper understanding of air conditioning heating in winter. Proper use of the air conditioning heating function can not only ensure comfort, but also achieve energy conservation and environmental protection, allowing you to stay warm throughout the winter.
