Number of air conditioners
Due to the differences in the specific system and electrical control design of different brands, the output cooling capacity also varies, so the cooling capacity is calculated based on the output power. Therefore, the so-called "horse" cannot accurately reflect the cooling capacity of the air conditioner. Only the cooling capacity parameters marked on the air conditioner model are accurate and scientific.
Cooling capacity is an important indicator of air conditioners. It refers to the total amount of heat removed from an enclosed space, room, or area per unit time when the air conditioner is performing cooling operation. The legal measurement unit is W. The unit of cooling capacity of a civil air conditioner is "horsepower", 1 horsepower = 2324W.
Fixed frequency air conditioner
The speed of the internal compressor motor is constant, and the temperature is adjusted by switching the compressor on and off. Because the power supply frequency cannot be changed, the compressor speed of the traditional fixed-frequency air conditioner is basically unchanged, and the indoor temperature is constantly adjusted by turning the compressor on and off. The room temperature may be suddenly cold and hot when it is turned on and off. More power.
Inverter air conditioner
Inverter air conditioner is an inverter added to the structure of conventional air conditioner. Adjust the voltage conversion through AC frequency conversion or DC frequency conversion to reduce the circuit loss, thereby achieving the purpose of more power saving and energy saving compared to the fixed frequency technology.
It adopts the design of split-type host and external unit, which is not restricted by the installation position, has a small cooling capacity and noise, does not take up space, and is suitable for use in bedrooms or small rooms.
The appearance is beautiful, which can increase the indoor decoration function. Generally, the cooling capacity is large, and the temperature control accuracy is high. It is suitable for living room or large rooms.
Traditional refrigerants are one of the most widely used Freon refrigerants, which have a great impact on the ozone layer and endanger the human living environment and the overall ecological environment. They have been gradually phased out.
A new environmentally friendly refrigerant that does not damage the ozone layer and has a working pressure of about 1.6 times that of ordinary R22 air conditioners. It has high cooling (warming) efficiency and improves air conditioning performance.
Electric heating and cooling
It is an auxiliary starting device for air conditioners when the outdoor temperature is low. When the heat pump air conditioner is heating, the external unit is cooling. If the ambient temperature is lower than 5 degrees, the external machine will frequently stop the defrosting. At this time, the electric heating is turned on to assist the heating. It is actually a set of independent heating devices.
In addition to formaldehyde
Formaldehyde removal air conditioner is a brand new air conditioning technology that integrates the formaldehyde removal module in the air conditioner, adopts the most advanced RCD formaldehyde decomposition technology and modular integration technology, and uses the air conditioning circulating air to effectively remove indoor formaldehyde through the formaldehyde removal module in the air conditioner. Currently common in the Haier brand.
Silver ion antibacterial filter
Through the antibacterial technology treatment, silver ions are incorporated into the air-conditioning components, so that the air-conditioning components have strong antibacterial capabilities, and the antibacterial effect is significant and long-lasting.
Energy efficiency rating
It is a grading method to indicate the difference in the energy efficiency of air conditioners. Level 1 indicates that the power saving of the product has reached the international advanced level, and the energy consumption is the lowest. Level 2 is the second, comparing power saving; and so on. Products below Level 5 are not allowed to be produced and sold.
Energy efficiency ratio
The energy efficiency ratio of air conditioners is the ratio of nominal cooling capacity (heating capacity) to operating power. The higher the energy efficiency ratio of air conditioners, the more power is saved. The energy efficiency of air conditioners is an important parameter to measure the performance of air conditioners.
