Tianjin Tiansong air conditioning English trademark is pamosautc and Panasonic air conditioning English trademark --- Panasonic is a bit similar, some people may mistakenly think that there is a link between the two, but in fact it is unrelated to the two brands. Tianjin Tian Song this brand has not heard of before, online can not find the production company (Tianjin Tian Song Technology Co., Ltd.) corresponding information, so that the production of air conditioning quality, cooling performance and after-sales level of concern, do not recommend that you buy, we recommend that you buy a line of brand air conditioning, the following to explain some of the purchase of air conditioning to pay attention to the place.
buy air conditioning --- brandbrand is an enterprise after years of market practice and test, slowly condensed, is an enterprise as well as the technology, product quality and reputation of the symbol. Try to buy famous brand goods, its scale and production is large, there is a complete set of perfect quality management system, product quality is guaranteed, after-sales service system is also relatively sound and perfect, there will be no after-sales situation. Rather choose the brand, do not choose the miscellaneous brand.
Domestic more famous and strength of the air conditioning brand: the United States, Gree, Haier, Aox, Zhigao
Japanese air conditioning brands: Hitachi, Daikin, Panasonic, Mitsubishi Electric, etc.
Buy air conditioning --- frequency conversion or frequencyInverter air conditioning is based on fixed-frequency air conditioning. Fixed-frequency air conditioning based on the addition of a frequency converter that can be used to adjust the speed of the compressor - inverter air conditioning inverter, increased frequency control system. After applying inverter technology to air conditioners, the compressor motor speed becomes variable, thus making the amount of refrigerant compressed by the compressor variable, and then making the speed and amount of refrigerant circulation variable, with the end result being variable cooling or heating capacity and more precise temperature control.
The domestic grid voltage is 220 volts, 50 Hz, in this condition the air conditioner is called "fixed-frequency air conditioning". Because the power supply frequency can not be changed, the traditional fixed-frequency air conditioning compressor speed is basically unchanged, relying on a relay to control the compressor, the compressor is constantly "on and off" to adjust the indoor temperature, which is easy to cause the room temperature between on and off, and consume more power.
Inverter advantages:
Fine sound
Long time not shut down the use of electricity
Temperature control precision, high comfort
Fixed-frequency advantages:
Cheap
Suggestion: If used in the living room / dining room and other people in and out of the frequent area, you can choose fixed-frequency air conditioning. Because such areas are extremely poor space confinement and short use of time, inverter air conditioning will be in the case of maximum power cooling, can not play the characteristics of inverter air conditioning power saving.
If it is used in the room, study and other leisure space, the budget is recommended to choose inverter air conditioning, because you can get a better sense of comfort, the budget is tight recommended to choose fixed-frequency air conditioning, and inverter air conditioning gap is not big.
If it is used in commercial areas such as shopping malls and companies, it is recommended to choose inverter central air conditioning. Because the use of a long time, you can save more energy and cost.
Buying an air conditioner --- HorsepowerSome people may see the number of horse may be the first time associated with the horse, but in the field of air conditioning, the horse is actually a unit of power, which means a horse power. Pi refers not to the cooling capacity, but the power of the air conditioner, air conditioning, the larger the number of pi, the greater the cooling capacity, generally speaking, 1 pi air conditioning cooling capacity of about 2,000 calories, to the international unit of conversion should be multiplied by 1.162, so a pi of the cooling capacity of 2,000 × 1.162 = 2,324W, you can refer to the data in the table below to choose the number of pi.
Buy air conditioning --- energy efficiency levelAir conditioning power saving or not is an important reference data for us to buy air conditioning, when buying air conditioning, we can compare the "China Energy Efficiency Labeling" level, you can also Comparison of energy efficiency ratio, in the case of the same energy efficiency level, the greater the value of the energy efficiency ratio, air conditioning, the more energy efficient. 1 level of energy efficiency machine is the most energy-saving, but the price is also the most expensive, from the point of view of the cost-effective consideration, usually buy the 2 level of the more appropriate.
Buy air conditioning --- noise valueAir conditioning is used for cooling and heating, especially when sleeping, excessive noise will disturb our good night's sleep, so the noise decibel value is our choice of air conditioning is a more important reference index. We should pay attention to the noise value of the indoor unit of the air conditioner, usually, inverter air conditioning noise control will be better than fixed frequency air conditioning.
Summary: We first determine the brand of air conditioner we want to buy, then choose inverter or fixed frequency, then determine the horsepower, and finally according to the noise value of the air conditioner, the energy efficiency rating and special features to determine a good purchase model.
