Many owners want to know if they want to install central air-conditioning in their homes, what are the precautions in the selection and purchase; there are some problems that are easy to ignore in the design and use of air-conditioning. This issue of the small series summarizes the answers to some common questions. It is recommended that you do your homework before purchasing the central air conditioner.

First, in the living room, choose the location to pay attention to

The installation position of the central air conditioner is of course determined according to the way the ceiling is installed, and the guest restaurant is undoubtedly the best installation location. As shown in the figure, it only needs to be suspended in the aisle area of ​​the guest restaurant, which reduces the ceiling space and also has a distinct layering between the restaurants. Generally, the airflow mode of the side air outlet and the lower return air is adopted. The air conditioner indoor unit effectively affects the entire room of the living room, and the double louver is used for the air outlet to adjust the air supply direction of the air conditioner, and the central air conditioner indoor unit focuses on the air supply direction. Consider the common sofa area.

Tips: The strip outlet is divided into a single layer and a double layer. Generally speaking, the double-layer air outlet has a good effect and the airflow is more uniform. The double-layer air outlet can close the air outlet, and the single-layer air outlet can also be closed, but it is not dead. In terms of price, the double-layer air outlet is more expensive than the single-layer air outlet.

Second, through the adjustment of the tuyere, the equilibrium temperature

The position of the air outlet and the return air outlet of the central air conditioner is adjustable, and the commonly used methods are side air outlet and lower air return. It can also be applied to side wind, side return air, lower wind and lower wind. Although the double louvers of the air outlet are stationary, they can be manually adjusted as needed, and the direction of the wind is set. There are generally 2 cases:

A. Indoor machine is installed at a corner

The vertical louvers of the tuyere can be adjusted to the left, so that the airflow can better reach the human activity area.

B. The indoor unit is installed in the middle of the large space.

The vertical louvers on both sides can be adjusted to the two sides, so that the airflow can cover the entire space to the greatest extent, and the airflow distribution is uniform.

3. What is the difference between “one for one” and “one for more”?

The most primitive concept of central air conditioning refers to the large-scale water system. Later, it developed into a central air conditioner for homes, which has a one-to-one structure and a multi-structured central air conditioner. The central air conditioners of these two structures are suitable for different room types and user groups.

One-to-one structure of central air conditioning:

The combination of an indoor unit and an outdoor unit, which is suitable for small-sized owners, will cost less than multiple connections. Because it is a one-to-one structure, maintenance and other aspects are relatively independent. In addition, the one-to-one structure central air-conditioning outdoor unit is small in size and can be installed in the air-conditioned space reserved for the apartment, so that the balcony is released again.

One-to-many central air conditioning:

It is called multi-connected home central air conditioner, which is generally used in villas and other lack of air-conditioning spaces. The air conditioners in the rooms are all open for a long time. It is characterized by the indoor unit of multiple rooms connected to an outdoor unit, using an outdoor unit. The machine can meet the cooling and heating demand of the whole house, and the outdoor unit runs on the power of the required cooling capacity of the indoor unit. The air conditioner that does not open does not consume electricity, and the running cost can be effectively reduced.

4. What are the “number of horses”, “frequency conversion” and “fixed frequency”?

Compared with the fixed-frequency central air conditioner, the temperature effect of the variable frequency central air conditioner is more constant. From a professional point of view, constant temperature and room temperature are two concepts. Equilibrium is a concept of space, constant as a concept of time. Generally speaking, the temperature detected by the air conditioner's thermostat is the temperature of the return air inlet. If the detected temperature is relatively stable, the inverter air conditioner will automatically fluctuate around 0.5 degrees above and below the set temperature, and the fixed frequency air conditioner is set. The temperature will fluctuate around 1 degree, so from this point of view, the inverter air conditioner is more stable and can maintain the temperature balance.

Tips:

When it comes to the effect of air conditioning, the concept of "number of horses" will be mentioned. In the professional concept, the exact meaning of a horse is 2,500 watts per hour. But at present, almost all businesses have intentionally or unintentionally created some confusing concepts when explaining this concept. Therefore, in the actual purchase, we should use the power calibrated on the product nameplate as the direct reference value. According to the structure of the house, choose the air conditioner suitable for the room.

5. What kind of material outlets are popular in the market?

Generally, the air outlets that can be seen on the market include ABS material air outlets and aluminum alloy air outlets. Sometimes, for the effect of decoration, wood can be separately customized, but the price is high.

TIPS: It adopts the air outlet of ABS material, which is not easy to dew. Due to its metal characteristics, the aluminum alloy tuyere has good thermal conductivity, which makes the surface temperature of the tuyere material too low and is easy to condense dew; the wooden tuyere is prone to cracking or deformation due to the difference in hot and cold air outlet temperature.
