The bigger the number of horses, the better Don't get into the misunderstanding when buying air conditioners

Summer is a good time to buy air conditioners, and major air conditioner manufacturers have one after another promotion. So what should consumers pay attention to when buying air conditioners?

　　 Today, the editor of okmarts.com brings you six common misunderstandings in the purchase and use of air conditioners. Interested friends may wish to take a look.

The bigger the number of horses, the better? Don't get into the misunderstanding when buying air conditioners

　　 Misunderstanding 1: The concept of the number of horses

　　 In the professional concept, the exact meaning of a horse is the cooling capacity of 2500 watts per hour. But at present, almost all manufacturers and businesses always intentionally or unintentionally create some confusing concepts when explaining this concept.

　　Experts suggest that when consumers buy air conditioners, they should not just look at the number of horses introduced by the merchant, but should use the power calibrated on the product nameplate as a direct reference value. According to the different house structure, consumers can choose the air conditioner suitable for the room according to the house area of ​​100~130 watts per square meter per hour.

　　 Consumers should also carefully consider the impact of other environmental factors when purchasing air conditioners, such as: good or bad heat insulation, good sealing, window and door area and orientation, whether or not they are topped, etc. The worse the conditions, the corresponding increase in cooling capacity.

　　Misunderstanding 2: Air conditioning volume

　　 At present, many manufacturers focus on promoting small-size indoor models, but consumers can’t just focus on the volume of air-conditioning indoor units.

　　Some high-quality air conditioners are indeed compact and reasonable in structure, such as the use of multi-fold heat exchangers and double drainage systems to reduce the size of indoor units. However, more small-sized indoor units achieve the purpose of small-sized under the condition of losing performance and quality and saving materials.

　　 Therefore, an air conditioner with a larger indoor unit size does not mean that its technology is backward, and a small size indoor unit does not mean that the technology is advanced. Consumers should not use this size as a standard when choosing an air conditioner.

　　Misunderstanding 3: Energy efficiency ratio

　　 Energy efficiency ratio is an important indicator of air conditioners. The meaning of energy efficiency ratio is the ratio of output power to input power. In other words, the ratio of the power consumption of the air conditioner to the cooling capacity, which is the efficiency.

　　 At present, the energy efficiency ratio of fixed-frequency air conditioners is generally: the maximum is 2.8~2.9 when cooling, and it generally does not exceed 3.5 when heating. Inverter air conditioners are higher than fixed frequency.

　　 Knowing this data, consumers should learn to distinguish false propaganda from manufacturers or businesses. The current market even claims that their fixed-frequency air conditioners can achieve an energy efficiency ratio of more than 5, so consumers should not be misled.

　　Misunderstanding 4: Low temperature start

　　 Low temperature start is currently becoming the focus of some manufacturers or merchants, but this "function" is not as magical as it is advertised.

　　According to experts, low-temperature start is not a difficult function to achieve, and its practical significance is not great. When the outdoor temperature is too low, if the air conditioner is allowed to heat, its energy efficiency ratio will be greatly reduced, resulting in little practical use.

　　Misunderstanding 5: Low voltage start

　　Like low-temperature starting, low-voltage starting is not a difficult technology, and the long-term failure of the air conditioner to work under the rated voltage will directly affect the service life of the air conditioner.

　　 Low-voltage start-up and low-temperature start-up are mainly the needs of manufacturers or businesses in publicity, and they have no practical significance. Consumers should avoid being misled.

　　 Misunderstanding 6: Install at will

　　 After some consumers have purchased an air conditioner, they often only consider the factors of beauty or convenience when installing, and require the installer to install the air conditioner in an unreasonable position. This practice is likely to cause many problems in the use of the air conditioner.

According to experts, the outdoor unit of the air conditioner needs to be installed where the air is relatively flowing and unobstructed. Otherwise, it is easy to shorten the life of the air conditioner, greatly reduce its performance, increase power consumption, and even cause the air conditioner to fail to work at all.

　　 Therefore, consumers should try their best to adopt the suggestions of professional installers in the process of installing air conditioners.
