Many homeowners are curious about the process of installing central air conditioning in their homes and what they should consider when choosing and purchasing one. There are also several often-overlooked aspects during the design and usage of air conditioning systems. This article aims to provide answers to some common questions and offers practical advice for those planning to install a central air conditioning system.
First, Pay Attention to the Location in the Living Room
The placement of a central air conditioner is typically determined by how the ceiling is designed. The living room or dining area is usually the best spot. As shown in the diagram, it can be suspended in the corridor area of the dining room, which not only saves ceiling space but also creates a more defined spatial layout. Most systems use a side air outlet with a lower return air setup. This ensures that the indoor unit effectively cools the entire living area. A double louver is often used on the air outlet to adjust the airflow direction, making sure the air reaches key areas like where people sit.
Tip: Strip outlets come in single-layer and double-layer versions. Double-layer outlets generally offer better performance and more even airflow. They can also be closed off, while single-layer ones can be closed but not completely sealed. In terms of cost, double-layer outlets tend to be more expensive than single-layer ones.
Second, Adjust the Air Outlet for Balanced Temperature
The position of the air outlet and return air inlet in a central air conditioning system can be adjusted. Common setups include side air outlets with lower return air, as well as side-to-side or bottom-to-bottom configurations. Although the double louvers on the air outlet are fixed, they can be manually adjusted to control the direction of the airflow. There are two typical scenarios:
A. When the indoor unit is installed in a corner
Adjust the vertical louvers to the left so the airflow reaches the most frequently used areas.
B. When the indoor unit is placed in the center of a large space
Adjust the louvers on both sides outward to ensure even coverage across the entire room.
3. What's the Difference Between "One-to-One" and "One-to-Many"?
The original concept of central air conditioning was based on large-scale water systems. Over time, it evolved into home central air conditioning, which comes in two main structures: one-to-one and one-to-many. These systems are suited for different types of homes and user needs.
One-to-One Central Air Conditioning:
This system consists of a single indoor unit paired with an outdoor unit, ideal for smaller spaces. It’s more cost-effective than multiple connections and allows for independent maintenance. Additionally, the outdoor unit is compact, making it easy to install in a dedicated space, thus freeing up the balcony.
One-to-Many Central Air Conditioning:
Also known as multi-split home central air conditioning, this system is commonly used in villas or larger homes with limited installation space. Multiple indoor units connect to a single outdoor unit, allowing it to meet the cooling and heating needs of the entire house. The outdoor unit only uses the power required by the active indoor units, reducing energy consumption and operating costs significantly.
4. What Are “Horsepower,†“Inverter,†and “Fixed Frequency�
Compared to fixed-frequency systems, inverter air conditioners provide more stable temperature control. From a professional perspective, “constant temperature†refers to time stability, while “balanced temperature†relates to spatial uniformity. Typically, the thermostat in an air conditioner measures the return air temperature. If this temperature remains stable, an inverter unit will maintain the set temperature within a range of ±0.5°C, while a fixed-frequency unit may fluctuate by around ±1°C. Therefore, inverter systems are more efficient and provide better thermal balance.
Tip:
When discussing air conditioning performance, the term “horsepower†is often mentioned. In technical terms, one horsepower equals 2,500 watts per hour. However, many companies use this term loosely, causing confusion. For accurate reference, always check the rated power on the product label and choose an air conditioner that matches your room size and structure.
5. What Materials Are Popular for Air Outlets?
Common air outlets found in the market are made from ABS plastic or aluminum alloy. Some people also choose custom wooden outlets for aesthetic reasons, though these tend to be more expensive.
Tip: ABS outlets are less likely to develop condensation, while aluminum alloy outlets have good thermal conductivity, which can lead to surface condensation. Wooden outlets are prone to cracking or warping due to temperature differences between hot and cold air.
The JUK universal Screw Terminal Block series has the typical features which are decisive for practical applications:
l The universal foot allows the terminal blocks to be easily snapped onto the NS35 or NS32 DIN Rail with G shape.
l Closed screw guide holes ensure screwdriver operation perfect.
l For terminal block with different wire cross-sectional areas, complete accessories are available, such as end plates, partition plates, etc.
l Potential distribution achieved by fixed bridges in the terminal center or insertion bridges in the clamping space.
l Same shape and pitch Grounding Terminal Blocks as the JUK universal series.
l Adopt ZB marker strip system,achieve unified identification.
