Central air conditioning purchase tips:

 

1. Focus on the applicability of central air conditioning

 

The central air conditioners for different room types are different. Only the actual central air conditioning can be selected according to the actual housing conditions. Specifically:

 

Select the model according to the area and orientation of the house: First, consider the area and orientation of the house to see if there is a large area of ​​glass windows to calculate the maximum simultaneous use factor of the air conditioner. Generally speaking, in the ordinary home environment, the amount of cold required for actual use is often not the sum of the total room cooling capacity, but lower than the latter. The former only needs to reach 60% and 70% of the latter . This saves investment and avoids unnecessary waste.

 

The actual required cooling capacity of the room can be calculated by the following formula: actual cold area = building area × house utility rate × 65% ( excluding uncooled area such as kitchen, bathroom, etc. ) , actual required cooling capacity = actual cold area × unit Area cooling capacity; note that the cooling capacity per unit area varies according to the specific situation, and the household is usually 100~150 watts / square meter. If the room faces south, the floor is high, or there is a large glass wall, it can be raised to 170~200 watts / square meter.

 

2 , pay attention to the three quality indicators of central air conditioning

 

People choose home central air conditioning, in large part to improve their quality of life and improve home comfort. Therefore, comfort has become a problem that must be considered when choosing a central air conditioner for home use. Comfort is generally considered from two aspects: temperature adjustment and mute. One is that there is no problem such as sudden cooling or temperature imbalance in the room, and the other is an indoor unit. The noise during operation should not be too large.

 

Three quality indicators for central air conditioning:

 

(1) Refrigeration ( heat ) amount

 

The amount of heat removed from the confined space by the air conditioner during the cooling ( heat ) operation, the legal unit of measurement is W ( Watts ) . The national standard stipulates that the actual cooling capacity of air conditioners should not be less than 95% of the rated cooling capacity .

 

(2) Energy efficiency ratio

 

It is the ratio of the cooling capacity to the cooling power when the air conditioner is cooling, in units of W/W . National standards stipulate that the energy efficiency ratio of 2500W air conditioner is 2.65 ; the energy efficiency ratio of 2500W to 4500W air conditioner is 2.70 .

 

(3) Noise

 

The noise generated during the operation of the air conditioner is mainly generated by the internal evaporator and the external condenser. The national air conditioner indoor unit with a cooling capacity below 2000W shall not exceed 45 decibels, the outdoor unit shall be no more than 55 decibels, the indoor air conditioner of 2500W to 4500W shall be no more than 48 decibels, and the outdoor unit shall be no more than 58 decibels .

 

 

 

 

3 , it is recommended to choose professional brand products

 

At present, there are many brands of home central air conditioners, which are dazzling for consumers. When purchasing, it is best to choose a professional brand with excellent quality. Central air-conditioning As the market has just started, many manufacturers have entered the market and it is inevitable that they will be mixed. Central air-conditioning is another industry with a high threshold, and it cannot survive for a long time without certain technical strength. Therefore, the central air-conditioning must choose a well-known brand, do not be greedy for a short time and eat big losses.

Compared with ordinary split air conditioners, home central air conditioners are actually a “semi-finished product” because it has to be matched with interior decoration. The service of home central air conditioning not only includes after-sales service, but also includes pre-sales consultation, program design, installation and construction. It can be said that to make a home central air conditioning system function properly, the design, installation and construction are as important as the host equipment. Therefore, when users purchase home central air conditioners, they must choose a good service and good reputation to protect their own interests.

 

5 , pay attention to the acceptance of the main parts and supporting materials

 

Consumers can initially check the quality of air conditioners by looking, listening, touching, etc. When the manufacturer sends the air conditioner to the consumer's home device, the plastic parts should be smooth and even in color, and there should be no air bubbles, scratches or leaks on the surface of the sprayed parts. The coating, the primer layer are exposed, the unevenness is uneven, and the function selection buttons on the computer-controlled air conditioner, the remote controller, and the line controller are light and flexible. In addition, the installation supporting materials must have a quality guarantee and performance test report to ensure the quality is stable.
