Power saving is the last word! Read energy efficiency labels in one minute

With the improvement of living standards, household central air conditioners have gradually become the new darling of modern families. Compared with ordinary air conditioners, the "invisible installation" of central air conditioners is not only suitable for matching with various styles of home decoration, but also has a very obvious comfort effect. However, there are also many users who report that the energy efficiency label of the central air conditioner at home seems to have "problems". There is a clear discrepancy between the cooling power of the outdoor unit in the product manual and the energy efficiency label. Is it because the business has played a trick of hacking?

Generally speaking, the cooling power on the energy efficiency label of the outdoor unit of the household central air conditioner will be higher than the power number shown in the manual. Judging from the feedback of many users, this phenomenon is common in mainstream household central air-conditioning brands on the market.

In this regard, industry experts pointed out that the difference between the input power of the central air-conditioning energy efficiency label and product manuals and brochures is mainly due to the different objects they refer to. Generally speaking, product manuals, brochures, etc. describe the product itself, that is, the input power of the indoor unit and outdoor unit; the energy efficiency label on the outdoor unit represents the power of the entire air conditioning system, that is, the outdoor unit in the air conditioning system. The sum of the input power of the unit and all indoor units, so the latter data is obviously higher.

In addition, experts also pointed out that if the installation and use of household central air conditioners are unscientific, it may also cause the actual energy consumption to be too high. For example, the ratio of indoor and outdoor units is too large, and the temperature setting in summer is too low. , The temperature is set too high during heating in winter, and the installation does not meet the standard specifications. Especially in the installation process, some home pictures are cheap. As a result, unscrupulous engineering companies cut corners and choose poor materials in terms of copper pipes and insulation materials. As a result, household central air conditioners have poor insulation performance, which will increase the performance of the system in the future. Consumption.
