1. used to believe that air conditioning refrigeration required compressors.2., heating is usually electric wire, need compressor work?
1. The air conditioning model starts with KFR. It needs compressor when it is heated. In general indoor machine also has hot wire, used as auxiliary heating, heating can choose to use.2 types of air conditioning, beginning with KFD, heating without compressor, full use of electric heat wire (this model is relatively rare).3, air conditioning model KF start, can not heat.
The principle of air conditioning heating:The air conditioning device belongs to the vapor compression refrigeration, heating, refrigerant by throttling capillary action, internal heat exchanger for rapid evaporation absorbs heat in the outdoor machine, to absorb the heat of the compressor under pressure, the heat exchanger into the indoor unit, the refrigerant in the heat exchanger of the indoor machine in the heat and the compressor work from the outside the absorption of the heat generated is released into the room, then again through a capillary tube into the outdoor unit heat exchanger, so the cycle of heating.So the compressor still needs to work when the air conditioner is hot.
This depends on your air conditioner type, some are generally used, but some auxiliary heating and electric heating wire, or compressor, your air conditioner is marked, you look carefully, the following is the type introduction;Number one: means the product code (household room air conditioner with the letter K)Second: climate type (usually T1 type, T1 type, climate, environment, the highest temperature of 43 degrees, using T1 type code name omitted)Third: structure form code (air conditioner according to the form of structure is divided into integral and split type, integral air conditioner is divided into window type and mobile type, code name is: split type - F, window - C, mobile - Y)Fourth: function code (air conditioner according to function mainly divided into chanlengxing, heat pump type and electric type, the chanlengxing code is omitted, the heat pump type, electric type respectively R, D)Fifth: specification code (amount of custom-made cold quantity, expressed in Arabia numeral, 25 means 2500W refrigerating capacity).Sixth: Code of the whole structure classification or code structure type indoor unit classification (indoor unit structure is classified into the ceiling, wall, floor, patio, embedded, which were respectively named D, G, L, T, Q etc.).Seventh: outdoor unit structure code (outdoor unit code W).Eighth: factory design number and special function code, etc., allow to use Chinese phonetic alphabet, capital letter or Arabia numeral to express
