How much does it cost to install a 120㎡ central air conditioner? What is the standard installation process?
Nowadays, central air-conditioning has lifted the veil of mystery and has begun to enter thousands of homes, and it has gradually become a trend. More and more people will consider installing household central air-conditioning when decorating their homes. The household central air conditioner is not only comfortable and healthy, but also beautiful and fashionable, bringing a better home experience.
Everyone will consider the price when they consider installing central air conditioners. How much does it cost to install a central air conditioner at home? What factors affect the price of central air conditioning? Let's introduce it in detail below.
1. How much is the central air conditioner price?
Family central air-conditioning installation, generally small partners know some product brands and models, in the choice of central air-conditioning brand, you can choose according to your own judgment or the recommendation of relatives and friends around you, the installation price of central air-conditioning is higher than domestic.
For example, with a three-bedroom and two-living room of 120 square meters, if the budget is sufficient, you can choose Japanese brands such as Toshiba, Daikin, Hitachi, and Mitsubishi Electric, and the price is around0. 4Million-0.6Million
Of course, there are expensive reasons. The refrigeration encyclopedia here is not explained in detail. Before, we have published articles explaining major brands of air conditioners.
2. What factors affect the price of central air conditioning?
1.The air conditioner itself is the most important part of the price of household central air conditioners, especially indoor and outdoor units. Of course, there are auxiliary materials used in the installation, such as: refrigerant copper pipes (essentially), condensate pipes, insulation cotton, tuyere materials, branch pipes and signal lines, etc., all of which affect the final central air-conditioning installation price list Calculation.
2. Household central air-conditioning depends on the product for three points and installation for seven points. Sometimes a good installation will make up for the lack of the machine itself. But if the installation is not in place, it may bring you unnecessary trouble and loss.
Professional air-conditioning designers will tailor the installation plan according to customer needs and house types, and it is not directly mounted on the wall like traditional air-conditioning, and the pipeline is also exposed. It has stronger installation technology than traditional air-conditioning and requires a standardized professional construction team. Ensure its good use effect.
3. After-sales service of central air-conditioning affects the quotation. The after-sales service of the household central air conditioner is the responsibility of the dealer, that is, the unit that installs the air conditioner, so it is not that it is not associated with the manufacturer or the dealer after the installation is completed. The dealer will guarantee the installation materials and installation links, and the manufacturer will Their equipment is guaranteed, and the equipment warranty period will be implemented according to the product and related regulations. As far as the dealer’s one-year after-sales guarantee is concerned, it is very critical and important, and this is also an important factor affecting the price.
3. What constitutes the central air-conditioning installation cost?
Product price: The product is the most important part of the price of household central air-conditioning, especially the main unit and indoor unit of household central air-conditioning. In addition, there are some central air-conditioning auxiliary equipment, such as copper pipes, PVC pipe insulation, and PVC condensate. Pipes, delivery/return air outlets, etc., all belong to the product price category.
Design cost: The design and installation of household central air-conditioning is usually done in concealed installation before the water and electricity enters the site. Therefore, the central air-conditioning pipeline routing, internal unit installation position and air outlet installation method need to be specially designed, generally there will be special The designer carries out CAD drawing according to the user's room plan, and strives to perfectly combine the interior decoration effect.
Installation cost: The installation of household central air conditioners is very different from traditional air conditioners. It requires a professional air conditioner designer to tailor the installation plan according to user needs and room types, and it is not like traditional air conditioners directly hung on the wall with exposed pipelines. It is more technical than traditional air-conditioning installation and requires standardized and professional construction to ensure a good use effect.
After-sales cost: Central air conditioners are not associated with the manufacturer after they are sold, and central air conditioners also need to be protected during later use. Generally, the central air conditioner will have a certain warranty period after it is sold, and the cleaning of the central air conditioner within the specified period, these are the after-sales costs.
Fourth, standardize the installation process of central air conditioning
1.The internal machine is in place: the first step for the construction team to enter the site is to hoist the internal machine. As long as you pay attention to two points, you can avoid subsequent problems. The distance between the internal machine and the roof must not be less than 1 cm to avoid resonance with the wall when the machine is running. The internal machine must be hoisted and in a horizontal position. After installation, special tools need to be used to measure whether the machine is level.
2. Installation of the refrigerant copper pipe: After installing the internal unit, the refrigerant copper pipe can be installed. This is the most important part of the central air-conditioning installation process. All welding points should be welded between the copper pipe and the branch pipe, and there is no copper pipe and copper pipe welding.
3. Nitrogen filling and pressure keeping: This is a pressure test that must be performed on the copper pipe after the welding is completed. A certain pressure of nitrogen is filled into the copper pipe to maintain the pressure. The general pressure test time is 24 hours.
4. Installation of the condensate pipe: After the condensate pipe is connected from the internal machine to the outdoor or floor drain, maintain at least a slope of >1%.
5.Install the outdoor unit: the air outlet of the outdoor unit must be within 15 cm of the rear of the 50 cm unit without obstruction, and all floor feet must be installed with shock absorbers to ensure the normal operation of the outdoor unit.
6. Vacuum: After the external machine is installed, the refrigerant tube needs to be evacuated before the refrigerant is filled, and the air in the tube must be evacuated to keep the tube dry and free of moisture. Otherwise, the air and water will mix with the refrigerant to produce ice crystals. Equipment damage.
7. Filling refrigerant: After the above work is completed, you can open the refrigerant valve to release the refrigerant inside the external machine, start the test and check the pressure, and make appropriate supplements until the debugging is completed and the ideal working state is reached.
8. Air outlet measurement and installation: Usually the return air inlet will be installed together with the maintenance opening. The size of the air outlet must be consistent with the return air outlet of the internal machine, and there should be no misalignment, so that the best return air volume can be achieved; and sufficient maintenance space is guaranteed. If the ABS tuyere is used, there must be a certain amount of thermal expansion and contraction space when measuring the tuyere.
