▼ The outdoor case uses hot -dip galvanized steel plate+electrostatic spray coating process (rust -proof), which has a industrial style simple beauty.

▼ The size of the outdoor unit is 810x580x280mm. The 1.5P frequency conversion outdoor unit is much larger than I think, so users must also consider the installation space outside the wall.

▼ The specific model of the outdoor unit is KFR-35W/1P26-K1A1. The production date is the same as the indoor machine 2018-05-21. In the box under the label is the air conditioner circuit board.

终于凉凉的了!Kelon 科龙 1P26 大1.5匹一级变频冷暖空调评测

▼ There is a refrigerant information under the circuit board box. The specific model is R410A, which is a new type of environmentally friendly refrigerant and will not destroy the ozone layer. It is more efficient than the cooling (heating) of traditional R22 refrigerant, but the work pressure is greater.

▼ Remove the circuit box to see the circuit connector inside.

▼ The connector of the inner and outer machine

▼ The back of the back is full of open design. You can see a large area of ​​copper pipes and fins. The heat exchange area is still guaranteed. But still a little worried that the fins will be deformation and damage, but fortunately, it has not happened.

终于凉凉的了!Kelon 科龙 1P26 大1.5匹一级变频冷暖空调评测

▼ The upper layer of the camera is relatively easy to disassemble, and there is a sponge on the upper layer of the fins to provide buffer protection.

▼ After opening the lid, you can first see the wiring diagram of the outdoor unit

▼ Double -row evaporator.

▼ You can see the fan and motor of the three-leaf. The motor is a DC brushless motor. The manufacturer is Japanese Zhibu, the model: SIC 52FV F130-3.

▼ I want to remove the front shell on the front of the outer unit, but there is a screw that is too strong. If you ca n’t remove it yourself, you want to install the staff to help remove the machine when you come to the door. , Can’t bear responsibility. Therefore, other important components can only look at the manufacturer’s promotional pictures: the compressor is a rare earth compressor, the advantage is that the energy efficiency ratio is high, and the service life is very long; To a more accurate temperature control, indoor and outdoor motors are DC, energy saving and environmental protection. Essence

终于凉凉的了!Kelon 科龙 1P26 大1.5匹一级变频冷暖空调评测

The principle of air conditioning: refrigerant (gas phase) is compressed by compressor and then cooled (the fan of the outdoor unit) is condensed into a high -pressure liquid. Then decompress and evaporate in the evaporator, absorb the surrounding heat, make the surrounding air be cold and send the cold air to the room to achieve the purpose of reducing the indoor temperature. The refrigerant that becomes a low -pressure gas phase enters the process of cycle of the compressor again.

In fact, the most basic principle of air conditioning is the liquid transformer gas absorption of the liquid in the textbook of middle school (the gas becomes liquid heat insulation). In this process, the maximum energy consumption should be the compressor, so the efficiency of the compressor is related to the energy consumption of the entire air conditioner. The inverter air conditioner adds a inverter to the structure of the conventional air conditioner. The function is to control and adjust the control system of the compressor speed to make it always in the best speed state, thereby improving the energy efficiency ratio (more than the conventional air -conditioning energy saving energy saving energy. At least 30%), achieve the purpose of energy saving.

Air conditioner installation

The installation line on the installation appointment is enough (4008011111), and then the local after -sales installation company calls you to confirm, and the master who installed will call the installation time with you. Since we are not too hot here in early July, it is easy to make an appointment to the weekend. Later, the installation master said that by the peak season of installing the air conditioner in August, it was not a good appointment.

▼ After the master comes to the door, you will first clarify the installed charging standards with you, and be consistent with the Internet. I only knew that Kelon Air Conditioning was now a subsidiary of Hisense. In addition, you will not have to invoices and purchase records (of course, you will ask the purchase channel), as long as the QR code on the air conditioner is authentic. The master joked that we would install it even if you stole the air conditioner.

The installation master was a bit unhappy about me that I had opened the package. It was said that the formal program was to disassemble the packaging at the scene. If it was found to be damaged, you could ask for replacement or return. It would be difficult to make it clear if you had any problems. Fortunately, my air conditioner was not damaged. Consumers still pay attention to the procedures of the manufacturer to avoid the situation of the leather. I first disassembled the packaging to take pictures for public testing.

▼ Before the installation, first connect the power supply of the inner and outer machine, and start the installation after seeing it.

▼ The installer is a group of two people, one master goes to the interior wall hanging on the wall, and a master is dealing with pipelines and lines. The copper pipe used for circulating cold agents is only three meters. If the distance between the unit and the indoor unit is too far, the tube must be added. The standard for charging is 90 yuan/meter.

▼ The indoor machine is connected to the copper pipe, and the wrench is tightly sealed. Then wrap the copper pipe, water pipe and wires together.

终于凉凉的了!Kelon 科龙 1P26 大1.5匹一级变频冷暖空调评测

▼ The developer left the holes of the air conditioner on the bedroom wall. It was hidden with foaming and Dabai during decoration. Now it is opened again. The master is still very careful.

终于凉凉的了!Kelon 科龙 1P26 大1.5匹一级变频冷暖空调评测

▼ Another master was punching with electric drills, and then found the level and followed the wall -mounted frame. This wall -mounted frame was fixed on the indoor machine and stainless steel. Then the two masters installed the indoor machine together.

▼ Then it is necessary to install the outdoor unit. A master is needed to install it outdoors. On the 4th floor of my house, the seat belt is tied directly on the guardrail of the corridor, which is still dangerous. The air conditioner reserved by the developer was installed under the window, but I beautified this layer with brick, the surface was uneven, and the punch was not well positioned. After the negotiation, I decided to install it on the leaned part, and then install the bracket.

▼ In case of preventing the air conditioner, when the air conditioner is carried out, the aircraft also tied to a seat belt.

▼ The air conditioner is moved outside and installed on the bracket, and then connected to the pipeline and wire.

▼ After the air conditioner is installed, the vacuum is first, because the air in the pipeline is available in air, which will directly affect the cooling effect of the air conditioner. The master pumps vacuum with its own vacuum pump. It took about 20 minutes in total.

▼ After the vacuum is completed, the gas liquid tube valve is turned on, and then the air conditioner is turned on, and the connector is detected by soapy water.

▼ The final test is: On the air -conditioning fin inside the interior, it was on a glass of water to see if the water can be smoothly remitted into the inner tank and discharged from the wall through the air -conditioning drainage pipe. This part will definitely condense the water vapor in the air when refrigerating (or dehumidification).

▼ After the inner and outer aircraft are installed, the master also puts the outdoor label on the interior and hangs up. After changing or repair, you must look at the tag of this barcode.

▼ Because the wall through the wall is reserved by the developer, the diameter is slightly greater than the pipeline, and it will be sealed with its own putty. As soon as my family is renovated, it is just a bit of foam glue. Leakage.

▼ The exposed pipeline can be used on the curtain, which will not affect the overall aesthetics

Essence

▼ The filter is still very easy to remove and clean.

▼ The installation master recommends a helmet for air conditioning, which can have some rainproof effect. The price is 150. I also know that it is not worth the price, but in the future, I can’t climb out of the window to install it myself. Out of the purpose of cherishing the air conditioner, the purpose of cherishing the air conditioner is the purpose of cherishing the air conditioner. I still bought one.

▼ It rained the next day, this “hat” still played some role

The main selling point of the official publicity is: cat steps silent, fast and warm, natural and dampness, internal and external cleaning, etc., let’s test the effect of this Kelon Kelon 1P26.

▼ The remote control of air conditioners and all features. The remote control should be suitable for many models. This model does not have the function of left and right wind. In addition, the upper right corner of the remote control is the temperature collector, allowing the temperature and setting temperature error of the remote control to place the temperature and setting temperature. Of course, the indoor machine also has a temperature probe, which can also be cut into the probe on the indoor machine as the monitoring point.

▼ There are still windy winds.

▼ Press the display switch in the remote control settings, the inner machine can display the real -time temperature, otherwise the setting temperature is displayed. In addition, the size of the outlet is measured to calculate the air volume.

The bedroom is about 11 ~ 12m2, the living room and the dining room are connected about 30+m2, and it is difficult to move from the living room. Therefore, it is installed in the bedroom after tangling. No problem.

▼ The air conditioner is near the window. The test point A is in front of the air conditioner out of the air conditioner. The test items include: wind speed, noise; test point B on the bedside table far from the air conditioner (almost diagonal line). The test items include: noise, temperature, and The humidity is roughly as shown in the figure below.

In terms of power consumption, because it is a variable frequency air conditioner, the change in power consumption is still quite large. From 700W to 900W, the cooling rated power of the product nameplate standard is 840W (minimum 80W, the maximum 1500W), and the air conditioner is basically running near the rated power. This value should be adjusted according to the temperature condition to adjust the compressor power, so you can see that the power consumption is also high when the small air measurement is measured below.
