Changhong air conditioning model letter is what awareness
The national unified air conditioning model naming method is "① ② ③ - ④ ⑤ ⑥ / ⑦ ⑧",
Each position of the air conditioning model is the same as the one in the cabinet.
The significance of the letters or numbers represented in each position is explained as follows:
Position ① for the letters: the product code of the air-conditioning, K - household air-conditioning;
Position ② for the letters: the structure of the air-conditioning form, split - F; window type - C -F; window type - C; mobile type - Y.

KCD-46(4620 ): indicates an electric window type household air conditioner with a cooling capacity of 4600 watts.
KFR-25LW/E(5052LA): K - room air conditioner; F - split type; R - heat pump type; 50 -- cooling capacity 5000W; L -- floor standing; W -- outdoor unit code; LA -- light box panel.
1 hp = 2300W cooling capacity
1.5 hp = 3200W cooling capacity
2 hp = 4300W cooling capacity
3 hp = 5400W cooling capacity
5 hp = 7200W cooling capacity
The XXXXW above is not a power consumption of the W, just the output power, and the input power is not a matter of fact. Power is not a horse thing, upstairs is not quite accurate, China's conversion method is the European system, that is, 1匹于735W的耗电量, that is, 1匹电力=0.735KW/H. We often say that the compressor is running for 1 hour 0.735 words of power consumption, I do not know so that you understand it? Of course, in addition to the above conversion of horsepower and cooling capacity, there are some manufacturers set their own, such as a large 1 horsepower cooling capacity of 2500W, in fact, are not accurate, you can think of it as a common 1 horsepower. Because each horse = 0.735KW is only a theoretical value, you also have to count the fan, control boards, relays and other electrical appliances, power loss, which leads to a problem of energy efficiency ratio, about close to the 1 horse = 0.735KW of energy efficiency ratio is about high. It consists primarily of a refrigeration system for cooling and dehumidification and an air circulation and purification unit, and may also include heating and ventilation units (which may be assembled in a box enclosure or component systems designed to be used together), hereinafter referred to as an air conditioner.
2, heat pump
The refrigeration system that warms up the indoor air by switching the direction of operation of the refrigerant of the refrigeration system, absorbing heat from the outdoor low-temperature air and releasing heat to the indoor air, and may also include the air circulation and purification device, and humidifying and ventilating device.
3. Electric heaters for heating
Electric heaters that use only electric heating methods for heating, and electric heaters (including post-installed electric heaters) that use temperature switches and other switches (switches operated due to indoor and outdoor temperatures, etc.) to convert heat pumps and electric heaters for heating.
4. Auxiliary electric heaters for heating
Electric heaters (including later installed electric heaters) used in conjunction with heat pumps.
5, cooling capacity
air-conditioner refrigeration operation, the unit time from the confined space, room or area to remove the sum of heat, unit: W.
6, refrigeration power
air-conditioner refrigeration operation, the total power consumed, unit: W.
7, heat
air-conditioner for Heating operation, the unit of time into the confined space, room or area of the sum of the heat, unit: W.
8, heating power
air-conditioner for heating operation, the total power consumed, unit: W. (Note: only the heat pump heating function, the heating power consumption is called heat pump heating power consumption .)
9, Energy Efficiency Ratio (EER)
In the rated operating conditions and specified conditions, the air conditioner for refrigeration operation, refrigeration capacity and effective input rate ratio, which is expressed in W / W. The EER is the ratio of the cooling capacity to the effective input rate, which is expressed in W / W. The EER is the ratio of the cooling capacity to the effective input rate.
10, the coefficient of performance (COP)
Second, product classification

2, model naming
A, the product model and the meaning of the following:
-
B, model example:
Example 1: KT3C-35/A
indicates that the T3 climate type, the whole (window) cold air room air-conditioner, the rated cooling capacity of 3500W, the first retrofit design.
Example 2: KC-22C
Indicates T1 climate type, integral through-the-wall cold-air room air conditioner, with a rated cooling capacity of 2200W.
Example ......
What do the letters in Changhong air conditioner models stand for? For example: KFR-23GW/DHT1(W1-H)+1
KFR on behalf of the cold and warm machine, if it is KF is a single cold. R is the meaning of the dual-format. DHT1(W1-H) is a series, each series has certain characteristics, as if the cooling fast ah or noise ah and so on. As for the back of the +1 is on behalf of 1 level of energy efficiency. +2 is 2 level so analogous, the highest is five, but also the most power consumption ~
