How can we be without air conditioning in the scorching summer? As one of the commonly used household appliances in our lives, have you really understood the performance of air conditioning? There is a difference between frequency conversion and DC frequency conversion in air conditioning, and many homeowners may not be clear about the professional knowledge of air conditioning. So if you want to buy an air conditioner, don’t rush to buy it. First, learn more about air conditioning knowledge. Next, let’s take a look at the difference between variable frequency air conditioning and DC variable frequency air conditioning? What are the tips for selecting air conditioners?
What is the difference between variable frequency air conditioning and DC variable frequency air conditioning?
1、 DC variable frequency air conditioner refers to the use of powerful DC motors in the three core motors of the air conditioner (variable frequency compressor motor, indoor fan motor, outdoor fan motor). Through the integration of the three DC motors with a full DC control module for flexible adjustment and optimization of the matching air conditioning system, the excellent performance of the full DC variable frequency air conditioner is fully utilized.
2、 Variable frequency air conditioning is based on ordinary air conditioning, using a dedicated variable frequency compressor and adding a variable frequency control system. Its basic structure and cooling principle are completely the same as ordinary air conditioners.
3、 The main unit of the variable frequency air conditioner is automatically variable speed, which can provide the required amount of cooling (heating) according to the room situation; When the indoor temperature reaches the desired value, the air conditioner operates at a constant speed that can accurately maintain this temperature, achieving “non-stop operation” to ensure stable environmental temperature.
4、 I suggest you choose a full DC variable frequency air conditioner. I use Midea’s full DC variable frequency air conditioner at home, which has low decibels for indoor and outdoor operation, and is beautiful, energy-saving, and low-carbon.
What are the tips for selecting air conditioners?
1、 Identify the brand accurately
There are many air conditioning brands on the market now, and many home appliance stores have purchased their products. However, it is important to remind users to choose products under brands that are trustworthy and have guaranteed products. Only in this way can timely solutions be provided when there are after-sales problems with the air conditioning. If it is a small brand or a local issue, it may not be able to keep up in terms of after-sales or other services.
2、 Choose a good merchant
After selecting an air conditioning brand, consumers also need to decide where to purchase it. Choosing a business is particularly important when buying air conditioning. Strictly speaking, air conditioning is a semi-finished product that cannot be purchased from a store and used immediately. It needs to be installed and debugged by a professional team before it can be used. If the installation and debugging are not done well, it will bring a series of problems, such as incomplete air discharge, leakage at pipeline connections, and human caused failures during debugging. These not only affect the effectiveness of use, but also add a lot of troubles.
3、 Purchase by measurement
Strictly speaking, the selection of air conditioners is limited by the usage area, and the air conditioners that are suitable for different usage areas are also different. Therefore, the “horsepower” is used to measure the size of air conditioners.
4、 Clever timing
Purchasing household appliances may also experience price fluctuations due to the off-season and peak season. It is understood that the period from October of the previous year to the end of March of the next year is the off-season, while the period from April to September is the peak season. The price difference between the peak season and off-season is around 7% -10%. Therefore, when making a purchase, it is important to seize the opportunity, especially when it comes to promotional activities in large supermarkets.
