The length of air conditioning duct will affect cooling and heating. The longer the air conditioning tube is, the more power it consumes. Theoretically, the shorter the air conditioning pipe, the better, which can reduce the loss, reduce the burden of compressor and reduce energy consumption. Due to the limitation of objective conditions, it is necessary to lengthen the pipeline and calculate it accurately, strive for the shortest, lay the pipeline straight and minimize bending. Bending should be regular, and the pipe should not be squeezed to affect the fluid flow.
Because the air conditioner is a heat exchanger, the indoor temperature is higher than the evaporator temperature of the air conditioner during refrigeration, so that the evaporator of the air conditioner begins to condense and forgets to flow out of the room. If heating is just the opposite, because the outside temperature is low, the outdoor condenser of the air conditioner will begin to defrost after reaching a certain temperature, because the working environment temperature is too low, which will affect the working efficiency.
The role of air conditioning copper tube:
1. The connection between indoor unit and outdoor unit of air conditioner requires connecting materials. Copper pipes and aluminum pipes are widely used to connect indoor units and outdoor units of air conditioners. At present, air-conditioning copper pipes are widely used as air-conditioning connecting materials.
Because the refrigerant absorbs heat in the evaporator and then releases heat in the condenser, the outer side of the copper tube of the air conditioner is also connected with the heat sink, and the refrigerant (Freon, commonly known as snow seed) passes through the connecting pipe. Therefore, the quality of copper tube used in this refrigerant directly affects the refrigeration effect of air conditioning.
2. Generally, the prices quoted by decoration companies and maintenance companies are around per meter 100- 120 yuan, but in fact, when they buy them, they all buy them by kilograms, about one kilogram of 45 yuan, and when they repair them for you, they will set the price according to different air conditioners. Generally speaking, the price of copper tubes with different diameters is different.
3. Copper tube has high pressure resistance, is not easy to corrode and has a longer service life than aluminum tube; The thermal conductivity of refrigeration copper tube is far superior to that of aluminum tube, and its welding performance and mechanical strength are far superior to that of aluminum. Of course, the price of air-conditioning copper pipe will be more expensive than that of aluminum pipe.
