How do you convince a southern roommate to turn on the air conditioner when northerners find it cold

Southern roommates generally do not need to turn on the air conditioner in winter, which has a lot to do with the climate of the south, where the climate is relatively warm and rainy in all seasons, compared with this, we are different in the north, the weather in winter is dry and cold, every winter, there will be a headache because the air conditioning can not be turned on, at this time there will be all kinds of pitiful, to seek the sympathy of the southern roommate, generally this method is feasible and effective, the roommate is also very reasonable, we will also repay them in various ways.

The southern winter is wet and cold, and many southerners will not turn on the air conditioner in the winter. Because many southerners will feel uncomfortable blowing the air conditioner, if you really want to turn on the air conditioner, you can tell him, provided that the air outlet of the air conditioner is not facing other people's bunks. Otherwise, he would be very uncomfortable and would definitely not agree to open it.

If he still doesn't agree, it is recommended to buy an electric blanket.

Northerners are basically big grinning and speak very directly, so they should learn the way of the south when they speak, and be tactful, turning on the air conditioner is not a one-person thing, so you need to negotiate well on the premise of mutual respect. Northerners have warm winters, so they don't have the habit of wearing single clothes indoors, which is the opposite of southerners, so I think I should explain the differences to my roommates in detail, otherwise there is a risk that the conversation will collapse.

The friends in the south come to school in the north, because of the difference between the north and the south, so they are not used to it, empathy, I may be the same, so I also take special care of them, but one thing is to make people's heads big, the friends in the south are not used to turning on the air conditioner in winter, but the winter in the north is really too cold, so after many dormitory meetings, we all reached a consensus, buy a humidifier for the dormitory, and then turn on the air conditioner, try to meet all our needs, everyone agreed, It was a pleasure to get along with.

My roommate in the south said that they were reluctant to turn on the air conditioner because it would make him feel uncomfortable, depressed, and feel very dry, uncomfortable, etc., and he promised to turn it on for a few hours a day at the request of a few of us northerners, and turn it off when it was calmer, and we also bought a humidifier in the dormitory, so that he would not be so uncomfortable, so that both parties were more satisfied.

I have also experienced this kind of thing, in order to let my roommate in the south turn on the air conditioner, I promised to help him bring food when he was in the restaurant, and also help him when he fetched water, anyway, I actively did some small things to make up for the discomfort caused to him when he turned on the air conditioner, and promised him to turn it on for a while, and turn it off when it was warm.

When I was studying in the south, I found that the southerners are really able to tolerate cold, there is no heating in winter, and my roommates are reluctant to turn on the air conditioner.

The causes of the failure are:

1) There is a serious dirty blockage in the refrigeration system, which should be removed in time.

2) There is a serious ice blockage in the refrigeration system.

3) Residual air or other non-condensable gases in the refrigeration system, resulting in high pressure.

4) The fan does not rotate or the speed is too slow, and the circulating air volume is insufficient.

5) Refrigerant leakage or serious insufficiency.

6) The high and low pressure valve plates of the compressor are damaged or the paper pad is broken down, and the refrigeration system is difficult to form high and low pressure, so it cannot be refrigerated.

7) After the air conditioner is repaired, the length of the capillary tube to be replaced is too long or too short, and the inner diameter is too large or too small, resulting in a large or small refrigerant flow rate, which affects the refrigeration effect.

8) The air conditioner is not properly installed, and there is a phenomenon of running cold around the box; or exposed to the sun, or too close to a heat source.

9) The air-conditioned room is too large, the door is opened and closed frequently, or there are gaps in the door and window, and the cooling capacity leaks a lot.

Users can take different maintenance methods for different reasons.

The landlord can go to my drip space to have a look, there is a detailed introduction.

Usually, household air conditioners are shut down and deactivated in September, and they are not turned on until May and June of the following year, and they are out of service for more than half a year. Therefore, before the air conditioner is turned on, we must do a comprehensive "diagnosis", check whether the air conditioning equipment has "faults", according to the results of the inventory, under the guidance of professional and technical personnel, do a good job of maintenance and cleaning, the maintenance and cleaning should be in place, including the shell, body, and filter of the outdoor unit and the indoor unit, and then start the trial operation to observe the refrigeration speed and effect.

When the air conditioner is heating, the indoor unit blows hot air and the outdoor unit blows cool air, and this method of transferring outdoor heat to the room is called heat pump heating. When the air conditioner is running for heating, the temperature of the heat exchanger of the outdoor unit is lower than the air temperature, and the water vapor in the air condenses and forms frost on the heat exchanger. The air conditioner produced by the regular manufacturer has an automatic defrost function, and the indoor unit does not blow wind or cool air when defrosting, and the frost can be automatically removed under normal circumstances, but in snowy or foggy days, if the air conditioner runs for a long time, the snowflakes and fog water will freeze as soon as they contact the heat exchanger of the outdoor unit, so that a thick layer of ice armor will be formed in the defrosting cycle.

However, when defrosting, the ice is too thick to dissolve, so a sink made of ice forms in the lower part of the heat exchanger. When the air conditioner starts to heat up again, the water in the sink quickly turns into ice, freezing the heat exchanger, at this time, the heat exchanger of the air conditioner only relies on the upper part that is not frozen, the temperature will be lower, and the ice will be thicker, so as to form a vicious circle and finally the heat exchanger is all wrapped by a thick layer of ice armor, at this time, the heating effect of the air conditioner is very poor, and the ice armor is too thick, which will block the operation of the fan of the external machine, and may also hit the fan, or burn the motor.

In addition to regular maintenance of the air conditioner, it is also necessary to replace the air conditioner and carry out in-depth maintenance.

1. Seasonal maintenance of air conditioners. When the air conditioner is not used for a long time, in order to fully dry the inside of the air conditioner, it should first run in air supply mode for 4 hours, add some lubricating oil to the fan motor part, then cut off the power supply, and then cover the air conditioner with an envelope, and cover the outdoor body with a protective cover to avoid sun and rain. At the same time, wipe the remote with a clean, soft, dry cloth and remove the battery.

When reusing the air conditioner, it is necessary to do a basic cleaning and do an operation test.

2. In-depth maintenance of air conditioners. Professional and technical personnel are requested to carry out comprehensive and thorough cleaning and maintenance of the core components of the air conditioner from the inside to the outside, find the hidden problems of the air conditioner in time, effectively extend its service life, and be healthier and more energy-saving.

The in-depth maintenance of the air conditioner is generally sufficient once every 2-3 years.

Copy the basic common sense of choosing an air conditioner:

1. First of all, it is necessary to attack according to the room bai

The area determines the DU refrigeration capacity of the machine, that is, the output power, the usual standard DAO is 200 watts of square meters, and you can't buy it cheaply, and the effect is not good.

3. Brand, the representative brands of imported joint ventures are Panasonic and Mitsubishi Electric, and the domestic products are mainly Gree, Haier, Midea, Oaks, etc., and the cost-effective positioning of the products is different.

1. The high temperature weather in summer is generally around 35, so the indoor temperature of about 26 is the most suitable, and it is not easy to get sick. At the same time, the internal temperature is not too low, and the air conditioner is also more energy-efficient.

2. The air conditioner should be installed in meters. Generally, the air inlet of the air conditioner is in the upper half, and the air outlet is in the lower half, if the air conditioner is installed too high, the cold air that has been exchanged for heat exchange will be sucked back by the air conditioner before it sinks to the lower part of the room.

3. In the process of using air conditioning, in fact, dehumidification and refrigeration can achieve the effect of reducing indoor temperature, but the power consumption of the two is too different.

4. It is best to turn the air conditioner upwards so that the cold air can circulate from top to bottom. When heating, the air conditioner is directed downward, which can make full use of the physical characteristics of hot and cold air and communicate naturally.

There are five main aspects: the selection of air conditioning form, the selection of air conditioning refrigeration capacity, the selection of air conditioning quality, the selection of air conditioning functions, and the selection of new functions (concepts) of air conditioning.

1. Air conditioning form selection.

1) Window air conditioner: easy to install, small in size, light in weight, low in weight.

2) Cabinet machine: high power, strong wind, suitable for large area of more than 16 square meters of room or living room.

3) Split machine: not limited by installation location, easier to install and match indoors, and less noise.

4) One-to-many air conditioner: It saves outdoor space and is more economical than installing multiple split units at the same time.

5) Inverter air conditioner: It can control the operation of the compressor according to the ambient temperature, and has the advantages of rapid start-up, stable temperature control, high efficiency and energy saving, silent operation, and compact size.

2. Air conditioning refrigeration capacity selection.

1) Small 1 horse: suitable for 7-16 square meters. （2200w、2300w）

2) 1 horse: suitable for 12-18 square meters. （2500w、2600w）

3) Horsepower: suitable for 15-22 square meters. （3200w）

4) Horsepower: suitable for 16-24 square meters. （3500w、3600w）

5) Horsepower: suitable for 19-29 square meters. （4000w）

6) Horsepower: suitable for 21-32 square meters. （4500w）

7) 2 horses: suitable for 22-34 square meters. （5000w）

8) 3 horses: suitable for 30-55 square meters. （7000w、8000w）

9) 5 horses: suitable for 55-85 square meters. （12000w）

3. Air conditioning quality selection.

Beautiful appearance, good material, high thermal efficiency, low noise, low vibration, clear fan running speed, good high and low temperature start-up performance, accurate temperature control.

4. Air conditioning function selection.

It should be considered from the geographical point of view - in areas where the summer is hot and the winter is warm or the heating is sufficient in the winter, the single cooling air conditioner can be selected; In winter, it is colder and has no heating effect, and the cooling and heating air conditioner is more suitable.

5. The selection of new functions (concepts) of air conditioners.

Health is a function developed by some air conditioners, and its role is relatively limited. The use of negative ions and photocatalysts in healthy air conditioners can indeed play a certain role in air purification, but the relevant components should be cleaned and sun-dried frequently, otherwise the performance will be reduced. In fact, the best way is to turn off the air conditioner, and often open the doors and windows to allow indoor and outdoor air convection.

The basic knowledge of choosing an air conditioner is: the number of air conditioners, the refrigeration capacity of air conditioners, the energy efficiency of air conditioners and the fixed frequency or frequency conversion points, and only after mastering these points can you buy an air conditioner that you are satisfied with.

1. The number of air conditioners.

Generally speaking, the cooling capacity of a horse is 2000 kcal, which is enough for a room of about 15 square meters, but the cooling capacity of the air conditioner is not only related to power, but also related to technology and energy efficiency ratio.

For example, if a horsepower air conditioner is 1000 watts, it may reach 2000 calories of cooling capacity, then the energy efficiency ratio of the air conditioner reaches 2. So when we choose an air conditioner, we should not only ask how many horses it is, but also carefully look at its energy efficiency ratio.

2. Refrigeration capacity of air conditioning.

When the air conditioner is running for refrigeration, the amount of heat removed from the confined space, room or area per unit time is called the cooling capacity, and it is generally required that the measured cooling capacity should not be less than 95% of the nominal cooling capacity. Therefore, the higher the general refrigeration capacity, whether it is nominal or actual, it means that the higher the p number of this air conditioner, the faster it can achieve the cooling and heating effect.

3. Energy efficiency of air conditioning.

The energy efficiency of an air conditioner is how much cold air is produced by consuming the same amount of electricity, and the more energy efficient the air conditioner, the more energy efficient. In other words, the higher the EER, the lower the energy consumption of the air conditioner and the higher the performance ratio.

4. Fixed frequency or frequency conversion.

Fixed-frequency air conditioner, when you set a temperature target for a fixed-frequency air conditioner, and if the indoor temperature does not reach this set target, the compressor of the air conditioner will start working.

The inverter air conditioner is equipped with a transmission on the basis of the compressor. With the transmission in place, the air conditioner can adjust the speed of the compressor. Once the compressor is working, the transmission adjusts the speed of the compressor to control the cooling effect as the temperature in the room gets closer and closer to the set temperature.

Another point is that the inverter air conditioner is used for a long time to save electricity and blow comfortably, but it is cost-effective to open for a long time. Fixed-frequency air conditioners are cheap to buy, and the power consumption is fixed.

The basics of choosing an air conditioner:

1. Brand, choose a big brand, such as Midea, Gree air conditioner, etc., it will be more trustworthy.

2. The model of the air conditioner, when we choose the air conditioner, we should look at its specific model, power, etc., to see whether it meets our household or commercial needs.

When buying an air conditioner, you should pay attention to the brand and cost performance.

Due to the competition in the industry, some air conditioning brands disappear from the market every year, and after these brands are delisted, the maintenance of air conditioning becomes a problem. Because even if you find a dealer, the dealer will ask you to bear the repair fee because there is no manufacturer to pay for the repair, which is a very troublesome thing.

In addition to choosing a household air conditioner according to the suitable refrigeration capacity, it is also necessary to consider the cost performance of the air conditioner (cost performance = performance price), the higher the cost performance, the better, and the brand and service.
