Hello everyone, let me introduce to you, what does the standard central air conditioning budget list look like

The standard central air-conditioning budget is roughly composed of three parts: a configuration table, a specific quotation and a detailed list of auxiliary materials. If the customer knows more about the budget and the air conditioner offers a more professional quote, it will be difficult for the non-standard air conditioner to get involved.

　　 Let's take a central air conditioning budget plan as an example to see what needs to be paid attention to.

　　1, configuration table

　　 The configuration of central air conditioning is generally selected according to factors such as room type, area, and floor height. The indoor and outdoor models need to match.

　　 Note 1: Floor height cannot be ignored

　　Floor height is often neglected in some quotations. The apartment is okay. If it is a villa, the floor height is higher, and the number of corresponding air conditioners should be increased according to the specific situation.

　　 Note 2: The cooling capacity must be accurate

　　 The cooling capacity is calculated based on the unit cooling capacity. The unit cooling capacity is generally around 200-220w/㎡, multiplied by the area, is the cooling capacity of the indoor unit.

　　2, specific quotation

　　 After reading the configuration, let's take a look at the specific quotation. This is relatively simple. Check the brand model, quantity and price. The model and configuration table should be consistent.

　　 Note 1: The tuyere charges should be reasonable

　　Because some families take into account the effect of decoration, they will adopt a long air outlet, but in fact they only use an indoor unit, so the extra long air outlet will be charged separately.

　　 Note 2: Power responsibilities should be distinguished

　　 Air-conditioning power supply is generally installed by the decoration company commissioned by the owner. The indoor and outdoor units are usually reserved for 1.5m in length to facilitate the access of the air-conditioning service provider to the equipment and avoid future troubles.

　　3, auxiliary material list

　　As a semi-finished product, the central air conditioner is of course inseparable from auxiliary materials, and there are many materials involved. Improper selection of auxiliary materials will also affect the air conditioning effect. Some auxiliary materials are listed in the following table, which is not complete.

　　 Note 1: Copper pipe selection should be cautious

　　The copper pipe is used to connect the indoor unit and the outdoor unit. Its thermal conductivity, heat transfer efficiency, and airtightness are very important. Poor selection will cause refrigerant leakage. Pay attention to choosing copper pipes that meet the technical specifications of the air conditioner.

　　 Note 2: Insulation materials should match

　　Insulation pipes mainly play a role in reducing heat and cold loss, and rubber and plastic materials are usually used. The heat preservation is good, and the effect of the air conditioner is also good. Note that the specifications of the insulation pipe match the copper pipe. Of course, pay attention to the manufacturer.

　　 Note 3: Material loss should be reasonable

　　 There will always be losses in construction, which cannot be avoided, so there is no need to be too careless here. If you are not at ease, check and accept the materials when they enter the site and after completion, and you will know the actual amount.

　　 Water pipes should be made of materials with good sealing properties, and other materials such as nuts should be selected in line with national standards.

　　 Note 4: Choose the material of the tuyere

　　ABS and aluminum alloy are two common tuyere materials. ABS is less deformed and dew, but the price is slightly higher.

　　 If aluminum alloy is used, if the air supply temperature is too low, the outdoor humidity is high, etc., condensation will easily occur.

　　 Note 5: Pay attention to other expenses

　　 These costs are also to be listed separately. Some companies may save part of the cost, because they do not have a set of strict quotation budget system specifications, so it seems relatively flexible. What needs to be reminded is not to be confused by appearances.
