This is the air outlet of a household z-shaped central air conditioner. Central air conditioners are generally chosen for modern furniture decoration design.
Since the home central air conditioner is installed first and the decoration work comes later, the decoration plan must be determined when installing the home central air conditioner. On the basis of ensuring the air conditioning effect, the installation position of the air conditioner indoor unit and the direction of the air duct must be determined. Come down. Generally, the indoor unit is installed in a partial ceiling outside the aisle. The air duct can be concealed using a partial ceiling method, and then the size and position of the exposed air supply and return vents are determined.
Purchasing steps
Step one: Determine the host model
First of all, consider the area and orientation of the house to see if there are large areas of glass windows. This is used to calculate the maximum simultaneous use factor of the air conditioner.
Generally speaking, in an ordinary home environment, the cooling capacity required for actual use is often not the combined cooling capacity of all rooms, but lower than the latter. The former only needs to reach about 60% of the latter. ~70 is enough. This saves investment and avoids unnecessary waste.
The actual cooling capacity required in the room can be calculated by the following formula:
Actual cooling area = building area × housing practical rate × 65 (excluding non-cooling areas such as kitchens and bathrooms)
Actual required cooling capacity = actual cooling area square meters. If the room faces south, has a higher floor, or has a large area of ??glass wall, it can be appropriately increased to about 170~200 watts/square meter.
Step 2: Determine the indoor unit and air outlet
Determine the model based on the actual cooling capacity required. Each room or hall only needs one indoor unit or air outlet. If the living room If the area is larger or rectangular, you can add an additional indoor unit or air outlet. About one horse is required for every 12 square meters.
Step 3: Determine the layout of the air conditioner
1. The location of the host should have good ventilation and heat dissipation to facilitate maintenance and repair. At the same time, the location should be as hidden as possible to avoid affecting the appearance of the house and preventing noise from affecting the interior. ;
2. The location of the indoor unit should match the interior decoration layout. It is usually hidden in the ceiling or on the top of a high cabinet. Generally, indoor units are ultra-thin and only require a height of about 25 centimeters to be placed. When installing, pay attention to good return air to circulate the indoor air to ensure the air conditioning effect and air quality;
3. Pipe layout: The refrigerant pipes of the chiller are relatively thin, even if they are coated on the outside The insulation layer can also be conveniently hidden; pipelines need to be insulated throughout the entire process, and pipe fittings, valves, and metal fittings in contact with the pipeline must be insulated and wrapped to prevent condensation from dripping; pipeline materials generally use PP-R pipes, PVC-U pipes or aluminum-plastic composite pipes can be guaranteed not to be damaged for 50 years; all condensed water is concentrated or discharged nearby;
4. The indoor unit can add negative ion generators and purification and dust removal devices according to user requirements. , to further improve indoor air quality.
Step 4: Choose a product with a suitable price
The price of home central air conditioners is about 400 yuan/square meter. Brands, models, and the user's own needs, such as the choice of inverter or non-inverter air conditioners, heating or cooling alone, will all lead to price differences.
Step 5: Choose a service
Compared with ordinary split air conditioners, home central air conditioners are actually a "semi-finished product" because it must match the interior decoration. Services for home central air conditioners include not only after-sales service, but also pre-sale consultation, solution design, and installation. It can be said that in order for a home central air-conditioning system to operate normally, the design, installation, and construction are as important as the host equipment.
So when users purchase home central air conditioners, they must choose a company with good service and good reputation to protect their own interests.
Three indicators
Refrigerating (heat) capacity, energy efficiency ratio and noise level are the three most critical indicators to measure the quality of air conditioners.
Cooling (heat) capacity
The heat removed from a closed space by the air conditioner during the cooling (heat) operation unit time, the legal unit of measurement is W (Watt).
National standards stipulate that the actual cooling capacity of air conditioners should not be less than 95% of the rated cooling capacity.
Energy efficiency ratio
Also known as the coefficient of performance (COP), it refers to the ratio of the cooling capacity to the cooling power of the air conditioner during cooling operation, in W/W.
National standards stipulate that the standard value of energy efficiency ratio of 2500W air conditioners is 2.65; the standard value of energy efficiency ratio of 2500W to 4500W air conditioners is 2.70.
The better the COP value, the more energy-saving the air conditioner is. A cop value of 3.6 or above belongs to first-level energy efficiency.
Attention when purchasing
Choose based on your own needs. When choosing a home central air conditioner, owners must pay attention to the following points:
Choose a suitable home central air conditioner based on the structure of your home.
Choose a home central air conditioner based on the power supply of 220V or 380V that matches the room you are using.
Choose energy control for home central air conditioners based on the use and function of the room.
Pay attention to the brand of household central air-conditioning units. You should choose a manufacturer with a production base so that your service is guaranteed.
When designing and installing a home central air conditioner, the effect of home decoration must be considered to ensure beauty and coordination.
The design and distribution of home central air-conditioning systems must be checked by air-conditioning professionals.
Five tips
1. Different from the installation method of ordinary air conditioners, the design and installation of small central air conditioners must be done before the room is decorated. The host must be installed through the ceiling (or even placed on the bathroom ceiling). ) is installed or installed in the closet so that the host cannot be seen in the room, making the overall layout more concise and beautiful. Projects using this design are best installed during the construction process, otherwise it will affect the later decoration.
2. Household central air conditioners generally do not have a fresh air system. Even if it is an air heat pump type, the fresh air replacement can only reach 15. If you want to achieve better results, you need to add a fresh air system. For example, Beijing Sunshine 100 International Apartment is planning to add a fresh air system in addition to its central air conditioning system.
3. The outdoor unit of household central air conditioners will produce a certain amount of noise, but it is not very loud. However, it is best to install it on the balcony away from the bedroom.
4. The outdoor opportunity occupies about 1 square meter of the balcony area.
5. The service life of home central air conditioners is generally about 15 years, and the owner will need to spend money to replace it.
Ten factors
1. Choice. Choose a home furnishing market where consumers are satisfied or whose after-sales service is trustworthy.
2. Shop around. For goods of the same style and brand, quality, price, service, etc. must be considered comprehensively.
3. Function selection. When purchasing a central air conditioner, you need to consider the functions of the air conditioning system, such as the system can also provide heating, add air alarm and humidification functions, add filtration and dust removal functions, and add fresh air pen sterilization functions, etc.
4. Decoration. Since the home central air conditioner is installed first and the decoration work comes later, the decoration plan must be determined when installing the home central air conditioner. On the basis of ensuring the air conditioning effect, the installation position of the air conditioner indoor unit and the direction of the air duct must be determined. Generally, the indoor unit is installed in a partial ceiling outside the aisle. The air duct can be concealed using a partial ceiling method, and then the size and position of the exposed air supply and return vents are determined.
5. Heating. Under normal conditions, for single-user residences, it is not recommended to put heating and air conditioning together. There are two reasons: First, heating must be continuous throughout the heating period and cannot be interrupted. The use of air conditioning system functions requires that power and water cannot be cut off, otherwise the system will shut down. Even when no one is inhabiting, a minimum level of heating must be ensured to prevent indoor freezing; secondly, the heating of each household requires high equipment. Once a fault occurs, it must be eliminated as soon as possible. Only the user himself or the property department has the ability to repair it. Only in this way can the heating be guaranteed to be uninterrupted. Therefore, the best situation is to have the property provide unified heating or hot and hot water, so as to ensure that there is no interruption and avoid adverse consequences.
6. Install authorization. In order to ensure the installation quality and future use effects, only companies authorized by the manufacturer to install are authorized to install the corresponding home central air-conditioning system. Pay special attention to the fact that system warranty and host warranty are not the same thing. What the air-conditioning manufacturer guarantees is the performance of the air-conditioning machine, while the system effect is guaranteed by correct design and correct installation.
Installation common sense
Edit
① It is better to choose a larger machine rather than a smaller one. It is wrong to think that the size of the air conditioner can be reduced due to the small number of residents and the use of fewer rooms. Correct.
②The outdoor unit must be placed in a place with smooth ventilation. If the ventilation is not smooth, it will greatly affect the air conditioning capacity.
③ Generally, the indoor unit should not be placed on the top of the bathroom or kitchen. If it must be placed, a return air plan must be developed to avoid air return in the bathroom or kitchen.
④A maintenance opening should be left on the indoor unit to ensure future maintenance.
⑤Choose the location of the air supply outlet to allow wind energy to circulate in the air-conditioned area.
⑥The size of the air supply opening must ensure a certain size. Excessive air supply opening will affect the air conditioning effect.
How to choose a household central air conditioner? Houses are becoming more and more spacious, and the decoration is becoming more and more sophisticated. As people's requirements for a beautiful indoor environment are increasing day by day, home appliances have long become a part of home decoration. Common air conditioner styles The shortcomings of a single, bulky appearance were suddenly exposed, and it was no longer able to adapt to people's diverse needs. While ordinary air conditioners have been left out, household central air conditioners are gradually being accepted by the public because they can well match the home style and achieve beautiful and harmonious effects. In view of the hot sales of household central air conditioners on the market, experts remind consumers that choosing central air conditioners should be based on the conditions of the house. Choose an air conditioner according to the structure of your house and the expected decoration effect. The layout of some houses is not suitable for installing central air conditioners. If installed blindly, it will not only affect the use effect, but also cause unnecessary trouble such as rework.
How to choose an air conditioner according to room conditions? Houses with a floor height of less than 2.7 meters and a total area of ??less than 100 square meters are not suitable for installing central air conditioning. If the floor height of the house is less than 2.7 meters, the height will be less than 2.4 meters after the central air conditioner is installed. People will feel "top-heavy" in it, which will affect the living comfort. Therefore, it is best not to choose central air conditioning for houses with a floor height of less than 2.7 meters. When installing central air conditioning, you should also use the method of partial ceiling suspension to avoid a large area of ??oppression. Residential central air conditioners also have certain requirements for the house area. If the total area of ??the house is less than 100 square meters, it is not cost-effective to use central air conditioners. In this case, ordinary air conditioners are a wise choice. In addition, the placement of the outdoor unit also requires Note that outdoor units generally require 0.6 to 1 cubic meter of space. If there is not enough space outdoors, it will cause a series of problems for installation and use.
A house that is truly suitable for installing household central air conditioning needs to meet the following two basic conditions: first, the house must be tall enough, with a floor height of at least 2.7 meters; second, the house must be large enough, with a total area of ??more than 100 square meters. . Since there are many types of household central air conditioners on the market, even if the room meets the above standards, the choice must be based on the specific situation. Generally speaking, household central air conditioners on the market include water duct type, air duct type and variable frequency multi-split type. Among them, the water pipe type central air conditioner is a miniaturized and home-based version of the central air conditioner. The working principle is the same as that of the large central air conditioner. Different temperatures can be selected according to the specific conditions of each room. The comfort level is quite high. It is called "real". "Household central air conditioner" in the sense of "household central air conditioner", the most representative one is the water pipe household central air conditioner. This type of central air conditioner is mainly suitable for large-area residences such as duplex houses and villas with a total area of ??more than 200 square meters. In terms of comfort, the air ducted central air conditioner is worse than the water ducted central air conditioner
