How much do you know about air conditioning-introduction of technical parameters of central air conditioning

As a household product in the new era, there are many brands, diverse technologies, and different styles and prices of central air conditioners. How to choose a central air conditioner with high cost performance? Whether it is a brand or a variety of categories, it is not easy to distinguish. Just look at the technical parameters of the central air conditioner when you buy it. Technical parameters of central air conditioning: refrigeration capacity. The cooling capacity provided by the central air conditioner is the number of air conditioners (2500 W = 1), and the average household uses 220W per square meter. For example, if the room is12m2, the required cooling capacity is12m2× 220w/m2 = 2640w ≈ 65433. Comfort 100 network: it must be configured at 220W per square meter. Some non-standard companies can gain low-cost competitiveness if they are configured at less than 220 W, and it will be troublesome if the air conditioner is not cold enough. Technical parameters of central air conditioning: input power is simply how much electricity is used, and cooling capacity are two concepts. Input power can be seen on the nameplate of air conditioning. However, the nominal value is the maximum input power, that is, the power consumption at full load. Comfortable 100 network: some companies can also come up with product manuals, saying that the maximum power consumption is the input power of the compressor. In fact, the central air conditioning host and fan also consume electricity. If the water system and water pump consume electricity, so do the water pump and fan. Technical parameters of central air conditioning: COP usually refers to COP value, such as 3.7 or 4.2. The higher the COP, the more energy-saving and expensive it is. The COP of fluorine system is generally higher than that of water system, but it depends on the input power and who consumes electricity. This is not only because high COP saves electricity. Comfort100.com: Some merchants may tell you what my COP (energy efficiency ratio) is, but in fact they only say the highest COP value, which is actually unattainable. COP is also divided into the highest COP and the general COP, which is closer to actual use. Technical parameters of central air conditioning: refrigeration capacity ratio refers to the ratio of indoor terminal to outdoor host. For example, the total cooling capacity of the indoor terminal is 20KW, and the operation rate is 70%, that is, 20kW× 70% = 14kW. According to the principle of taking the actual model as the maximum, an outdoor host of about 15KW or 16KW can be used. If the utilization rate reaches 80%-90% at the same time, it will be equipped with about 19KW. Comfortable 100 network: the cooling capacity ratio must be clearly calculated according to the number of simultaneous operation rates, and it will be speechless when it is small. There are many new products in the central air-conditioning market in the past two years. Health air conditioning has various concepts such as photocatalyst, cold catalyst, oxygen bar, negative ion and nanometer. Comfort 100 reminds consumers not to be confused by these concepts. When purchasing, we must comprehensively consider the technical parameters of the central air conditioner, carefully check the performance indicators and certification marks of the air conditioner, and ensure that the most suitable high-quality air conditioner products are selected.
