When we choose to buy air conditioners, we haven’t gotten a shot and we've been dizzy with the energy efficiency ratio and voltage rating of the promoters. And what exactly do they mean? What is the relationship with the purchase of air conditioning? Today, the editor has brought them a detailed explanation of their meanings. A friend who wants to buy air conditioners may wish to refer to it.
(1) The meaning of horses (P): "P" is the abbreviation of power, and international "watts" means that the cooling capacity 1P is about 2500W.
Such as: 1.5P refers to the cooling capacity of 1.5 * 2500W = 3500W; 2P refers to the cooling capacity of 2 * 2500W = 5000W
(2) Energy efficiency ratio: (EER) The ratio of the cooling capacity to the effective input power when the air conditioner performs a cooling operation under rated conditions and conditions. EER = cooling capacity / input power, this value can test the performance of air conditioning, the greater the value, the better the system matching, air conditioning performance is superior, cooling, heating effect is better, the smaller the power consumption.
(3) Dehumidification: The amount of moisture removed from the air in a confined space, room, or area per unit time is called dehumidification. Unit: liters/hour (L/H)
(4) Rated voltage: It refers to the provisions of the allowable power supply voltage value of the air conditioner manufacturer or the allowable range of variation of the power supply voltage when the air conditioner manufacturer leaves the factory.
(5) Types of noise: Aerodynamic noise, mechanical vibration noise, Electromagnetic noise Source: Fans and compressors, noise range: indoor about 50 decibels, outdoor about 60 decibels.
(6) Rated power: When working under normal working conditions, the consumed electric power is the total allowable power of the air conditioner.
Our company`s current transformers have high precision,wide range,small volume and good linearity that can be used to the field of electronic watt-hour meter, electric energy metering, electronic detection.
Performance
1.Power frequency insulation strength:The insulation between the primary winding and the secondary winding and the ground part of the CT can bear 4kV power frequency voltage for 1minute
2.Interturn insulation strength:The secondary open circuit, the primary winding through the rated current 1min, no inter-turn damage in the transformer
3.The deviation is better than the industry standards and national standards
