How to heat an on-hook air conditioner
As winter approaches, many families begin to use the heating function of mounted air conditioners to keep warm. However, many users have questions about the heating principle and operation method of on-hook air conditioners. This article will introduce in detail the heating principles, usage methods and common problems of on-hook air conditioners to help everyone better use the heating function of the air conditioner.
1. Principle of on-hook air conditioning and heating
The heating function of the on-hook air conditioner is mainly realized through heat pump technology. Here's a brief explanation of how it works:
| steps | Description |
|---|---|
| 1. Refrigerant cycle | The air conditioner compresses the refrigerant into high-temperature and high-pressure gas through the compressor, and delivers it to the heat exchanger of the indoor unit. |
| 2. Heat release | The high-temperature refrigerant releases heat in the indoor unit heat exchanger, and the hot air is blown into the room through the fan. |
| 3. Refrigerant return | After the refrigerant is decompressed by the expansion valve, it turns into a low-temperature and low-pressure liquid and returns to the outdoor unit to absorb external heat. |
| 4. Repeat the cycle | The entire process repeats itself to achieve continuous heating. |
2. Operation method of on-hook air conditioner and heating
The following are the specific steps for using an on-hook air conditioner for heating:
| steps | Operating Instructions |
|---|---|
| 1. Turn on the power | Make sure the air conditioner is powered on and the remote control battery has sufficient power. |
| 2. Select heating mode | Press the "Mode" button on the remote control to switch to "Heating" mode (usually shown as a sun icon). |
| 3. Set temperature | Set the target temperature between 18-25℃ (recommended 20-22℃) through the "Temperature+" or "Temperature-" key. |
| 4. Adjust the wind speed | Select "Auto", "High", "Medium" or "Low" wind speed according to your needs. |
| 5. Start the air conditioner | Press the "On/Off" button and the air conditioner starts heating. |
3. Common problems and solutions for on-hook air conditioning and heating
When using an on-hook air conditioner for heating, you may encounter the following problems:
| question | Reason | Solution |
|---|---|---|
| Poor heating effect | The outdoor temperature is too low, the filter is clogged, and the refrigerant is insufficient. | Clean the filter, check the refrigerant, and avoid use at extremely low temperatures |
| Air conditioner does not heat | Wrong mode setting, power supply issues, sensor failure | Check mode settings, power connection, and contact after-sales service |
| There is a peculiar smell in the air | Filter or evaporator is dirty | Clean the filter and evaporator, using air conditioner cleaner if necessary |
| Too much noise | Fan or compressor failure, unstable installation | Check whether the installation is firm and contact after-sales service |
4. Precautions when using on-hook air conditioners and heating
In order to ensure the best heating effect of the hanging air conditioner and extend the service life of the air conditioner, please pay attention to the following matters:
| Things to note | Description |
|---|---|
| Clean the filter regularly | It is recommended to clean the filter every 2 weeks to prevent dust accumulation from affecting the heating effect. |
| Set the temperature appropriately | In winter, the indoor temperature is recommended to be set at 20-22°C. Energy consumption increases by about 6% for every 1°C increase. |
| Avoid frequent switching | Frequently turning the air conditioner on and off will increase energy consumption, so it is recommended to continue using it. |
| Keep the room airtight | Close doors and windows when in use to reduce heat loss. |
| Outdoor unit maintenance | Make sure there is no obstruction around the outdoor unit to prevent snow or ice from affecting its operation. |
5. Comparison between on-hook air conditioner heating and heater
The following is a comparison of on-hook air conditioning heating and electric heaters:
| Comparative item | On-hook air conditioner | electric heater |
|---|---|---|
| Working principle | Heat pump technology, transporting heat | Electrical energy is directly converted into thermal energy |
| Energy efficiency ratio | High (above 1:3) | Low (1:1) |
| Applicable area | Large (15-30㎡) | Small (local heating) |
| cost of use | lower | higher |
| security | high | Pay attention to fire prevention |
From the above comparison, it can be seen that the on-hook air conditioner has obvious advantages in heating efficiency and cost of use, and is suitable for heating large-area rooms; while electric heaters are more suitable for local rapid heating.
6. Summary
The heating function of the on-hook air conditioner is an efficient choice for heating in winter. Correct use and maintenance can not only improve the heating effect, but also extend the life of the air conditioner. It is recommended that users clean the filter regularly, set the temperature appropriately, and pay attention to the maintenance of the outdoor unit. Compared with electric heaters, air conditioning heating is more energy-saving and environmentally friendly, and is suitable for most families.
If you encounter problems that cannot be solved during use, it is recommended to contact professional maintenance personnel in time for inspection and maintenance to ensure the normal operation of the air conditioner.
