What should I pay attention to when installing a commercial air conditioner?

Precautions need to be taken in the installation and design of commercial air conditioners: First of all, the location of the air conditioning installation host should pay attention to good ventilation and heat dissipation, which is convenient for maintenance and maintenance, and the location should be as concealed as possible to avoid affecting the appearance of the house and noise affecting the interior. Secondly, the location of the indoor unit of the air conditioner installation should be matched with the interior decoration layout, which is generally hidden in the ceiling or hidden on the top of the high cabinet.

Generally, indoor units are ultra-thin and only need about 30 cm in height to be placed. In terms of the layout of the air conditioning pipeline, the refrigerant pipeline of the chiller is relatively thin, and even if the insulation layer is on the outer bread, it can be easily hidden; The pipeline needs to be insulated throughout the process, and the fittings, valves, and metal fittings that come into contact with the pipeline must be wrapped to prevent condensate from dripping.

First of all, the day after tomorrow according to the position of the host to pay attention to ventilation and heat dissipation, at the same time the location as far as possible to conceal, to avoid affecting the appearance of the house and noise impact indoors, the general host is placed on the balcony or storage room seven, four yuan, the location of the air conditioning installation should be compared with the strength of the makeup repair of the former residence configuration supervisor, I contact the metal fittings to wrap up, with water dripping.

1. Socket and switch.

When the air conditioner is not in use, the plug can be unplugged, but the socket of the general air conditioner is relatively high, and it is more troublesome to pull the plug and there is also a certain danger. Therefore, you can choose an outlet with a switch as an outlet for the air conditioner, which will be safer and more convenient. The socket should be close to the wall where the air conditioning hole is located, the general air conditioning line will not be very long, the air conditioner is installed in the upper half of the wall, and the socket of the air conditioner should also be placed in that position as much as possible.

2. Air conditioning location.

Many families do not carefully consider the location of the air conditioner when installing it. When in use, the incorrect installation position of the air conditioner will cause a certain impact on people's health, which can easily cause stroke diseases. For smaller bedrooms, no matter how you adjust the position, the air conditioner will be more or less facing the bed.

In this case, it is necessary to pay attention to the choice of air conditioner with sleep function and good silent effect when purchasing.

3. Air-conditioned hole.

The air-conditioning hole in the wall of the air conditioner is often overlooked, thinking that it only needs to be opened so that the pipeline can pass through. But in fact, when playing the air conditioning hole, it is necessary to pay attention to the outward inclination, that is, "low on the outside and high on the inside", which can prevent the air conditioner from backing up water into the house when it is in use.

4. Don't change the wires at will.

Do not change the wires at will, and do not increase the power of electrical appliances, so as not to increase the electrical load and form a risk situation of wires and electrical appliances. When using, be sure to pay attention to the safety of electricity.

5. Check the air conditioner after it is ready.

After the air conditioner is installed, check whether it can be used normally and check whether there is any problem with the device.

Plug in the power cord and turn on the air conditioner to see if it can be turned on normally, and whether the heating and cooling forms can be used normally. Whether the air outlet of the air conditioner is normal, and whether there are any strange sounds and noises. After opening it for a while, check to see if there are any water leaks in various parts of the guard.

Precautions should be taken when installing air conditioning: pay attention to safety when working at height; The bracket must be fixed and stable; The connecting copper pipe between the internal and external machine cannot be bent; The installation of the air conditioner unit should be inclined in the direction of the outlet of the drain pipe.

The details are as follows: 1. When installing air conditioners, we must pay attention to safety, especially for high-altitude work, and we must strictly follow the installation rules when installing, wear safety ropes, and be equipped with protection personnel.

2. The bracket for air conditioning installation must be fixed and stable, and the fastening bolts must be tightened when installing the external unit, and the test must be carried out after installation.

3. When installing the air conditioner, the copper pipe connecting the internal unit and the external unit should not be bent to avoid the copper pipe breaking and leaking fluorine, resulting in the air conditioner being unable to refrigerate.

4. The installation of the air conditioner should be inclined to the outlet of the drain pipe to avoid the condensate of the drain pipe from being unable to be discharged and backflowing, resulting in water leakage of the indoor unit.

In fact, it is relatively simple to install the air conditioner, and it is recommended that it is best to be completed by a professional installation staff, so as to avoid accidents or failures that cannot be handled by yourself, and the air conditioner is easy to leak if it is not installed well.

1. Look at whether the wall in the room where the air conditioner is installed falls off and other influences, so as to ensure the heat dissipation effect of the indoor unit and the favorable factors of wall safety.

Second, the installation position of the air conditioner should not be too low. Some families install air conditioners on window sills, which is not conducive to reducing the operating rate. Because "the cold air goes down, the hot air goes up", the air in the lower room is a mixture of hot and cold air.

If the air conditioner is installed on the window sill, the air temperature is low, and the air conditioner is relatively reactive power loss, and the hot air on the upper layer is not effectively cooled. Therefore, the air conditioner should be installed in a suitable location in the room in the back-lit room. In particular, do not install the air conditioner too close to the outdoor unit, which is easy to form resonance and cause noise.

3. The temperature of the air conditioner should not be too low, generally controlled at 24 degrees to 28 degrees or a little higher, as long as people do not feel hot. The temperature difference is large, people are easy to feel uncomfortable, and at the same time, the power consumption will increase several times.

Fourth, the installation process, must be cautious, can not blindly only follow the advice of the installer, just change the external environment, for example: can not because the outdoor unit of the air conditioner is large, the fixed outdoor unit iron railing removed, because this not only destroys the beauty of the community, but also loses the role of protecting the outdoor unit, easy to make the thief steal successfully.

Fifth, do not arbitrarily change the direction of the indoor wires and increase the electrical load, which is easy to cause air conditioning, resulting in a series of property losses. Finally, users are reminded to pay more attention to safe electricity use when using.

6. After the air conditioner is installed, the following inspections should be carried out:

1.First of all, plug in the power supply, turn on the air conditioner, and see if the air conditioner can run normally, cool or heat, and whether it is strong enough.

2.Pay attention to the condition of the air conditioner's air outlet, whether it swings normally, whether the air outlet is normal, and whether there is abnormal sound and noise.

3.After running for a period of time, see if there is any abnormal situation such as water leakage in the pipes of the air conditioner.

When we buy back the air conditioner, we use the above steps to determine whether the air conditioner is successfully installed, so as to ensure that we can use the air conditioner normally in our daily life in the future. In addition, we should remind everyone that there can be no obstructions in front of the installed air conditioner, and the jet distance of cold and hot air must be ensured, so that the indoor temperature can be relatively uniform.

Secure, secure and durable.

First, pay attention to safety, and second, be careful not to let the copper pipe get into the sediment.

2. Points to pay attention to when installing air conditioners.

1: The installation position of the air conditioner (energy transmission path, beautiful) 2: The horizontal position of the air conditioner installation (to ensure the circulation of condensate to avoid the phenomenon of water backflow) 3:

The treatment of wall holes (prevention and control of rain leakage and aesthetics, space sealing problems) 4: copper pipe (the copper pipe is flattened, which will affect the refrigeration speed and service life of the air conditioner. Poor connection of air conditioning pipes will cause air conditioner leakage and affect cooling and heating.

5: The external unit should be kept ventilated (whether the external unit is installed firmly and horizontally) 6: There is a detailed manual inside the air conditioner, which has a lot of relevant information (according to the manual).

7: Test machine of air conditioner (after installation, don't forget to ask the master to test the air conditioner, and the leakage of the air conditioner).

Each part is very important, the most critical is the interface of the connecting pipe (a total of 4 out), the drainage of the indoor unit, the level of the indoor and outdoor units, but the most important thing is safety.

Pay attention to the level and height of the installation of the internal machine, and choose the location of the external machine to be safe, firm and easy to maintain.

There is no big requirement, the indoor unit should be flat and horizontal, he will generate water smoothly to prevent water from flowing into the machine, and the copper pipe should not be broken.

If you do it yourself, you must pay attention to safety, do not wear a safety rope, and never put it on the shelf.

If you are injured, it is considered a work-related injury, and you should pay for medical expenses.

Examples of installation requirements are clearly stated in the manual, but there are too many words to provide them in detail here.

The air conditioner is bought in three points and installed in seven points.

I forgot if it was an American or a Japanese, and it took 2 days to install an air conditioner.

The air conditioner must be installed at the head of the bed, not at the end of the bed, to avoid the situation of cold wind.

If there is no way to fit it into the head of the bed, you can only move the position of the bed.

The internal machine has: height, horizontal pipe direction.

The external machine has: ventilation and whether the connecting pipe is in accordance with the regulations.

Precautions for air conditioning installation.

1.If the wall is a gray wall, the wall can be painted and decorated, which not only enhances the thermal insulation of the gray wall, but also saves electricity several times.

2.To prevent Freon leakage during the installation of the air conditioner, after the air conditioner is installed, be sure to let the installer perform a leak detection on the air conditioner connection port to prevent Freon leakage.

3.To prevent rainwater from pouring into the room from the wall hole, during the installation of the air conditioner, it is necessary to make a slightly higher indoor wall hole; After the installation is completed, the void of the wall hole must be plugged with putty, and if the drainage hole in the corridor is used, a similar problem should be noted.

4.To ensure that the condensate generated by the air conditioner during refrigeration can be discharged to the outside to prevent indoor water leakage, you can pour a little water into the water tray of the air conditioner during installation to check whether it can be discharged to the outside.

5.When the air conditioner is heated in winter, there will be water dripping out due to frosting, so it is necessary to prevent outdoor water leakage, so special attention should be paid to the installation of the outdoor unit outlet and outlet pipe when installing the air conditioner.

6.The outdoor unit of the air conditioner should not be installed anywhere, and its location should be conducive to future repair and maintenance; The installation of the outdoor unit (compressor) must be correct, and the installer must use a level to level it.

7.The outdoor unit bracket should be equipped with the specified bolts, and there must be enough of them, beware of workers omitting a few bolts for the convenience of construction, and there will be a lot of trouble in the future.

8.If the distance between the outdoor unit and the indoor unit is more than 3 meters, when adding refrigeration pipes and drainage pipes and wires, be sure to check whether the copper pipes and wires added are the same products used in the original air conditioner.

9.When extending the refrigeration copper pipe, the extended copper pipe will be welded on the original copper pipe by gas welding, and attention should be paid to requiring workers to weld with silver electrodes, and it is forbidden to use copper welding rods to weld, and the extended refrigeration copper pipes must be tightly wrapped with thermal insulation sleeves and wrapped with straps; It is also important to wrap the refrigeration pipe and wire drainage pipe with straps, so that the workers can do it safely, otherwise it will cause the rainwater to flow into the house when the plastic tape is not winded.

10.The ideal location for the installation of the outdoor group is the north or east wall, where there is less direct sunlight, if it must be installed on the south or west wall, there must be shading measures, but it must not obstruct air circulation; No obstructions should be kept around the outdoor unit to maintain good heat dissipation.

11.Outdoor units are installed on solid walls or balcony floors to reduce vibrations; The unit should be as close to the indoor unit as possible to reduce pipeline resistance and Freon loss.

12.The back (wall side) and sides of the condenser should be at least 20 cm away from the obstacle, and the front (outward exhaust side) should be more than 40 cm away from the obstacle.

13.There should be no obstruction in front of the indoor unit to ensure the jet distance of the cold air and make the indoor temperature relatively uniform.

14.The drain pipe must be straight and appropriately inclined outwards to facilitate the smooth flow of water; If there is an elbow in the middle of the drain pipe, it is easy to cause water accumulation and the flow of water is not smooth, resulting in the overflow of the indoor unit.

15.Air conditioners should not be installed together with coal stoves, gas stoves, and heating equipment, which is unsafe and not conducive to condenser heat dissipation.

The installation requirements for tooling commercial ** air conditioners are relatively high, so you must choose a professional HVAC engineering installation company. Comparatively speaking, the installation of air conditioning in the water system has higher requirements for the professionalism of technical personnel, and its outdoor unit can independently complete the whole process of the refrigeration cycle, which is a perfect system, relatively speaking, the indoor unit only plays a simple role in heat exchange, and the two are independent of each other, which shows that the system of the water machine is more scalable, and the end selection is more flexible when configuring the system, and the compatibility of different brands is high.

**Comparison of air conditioners, water machines, and fluorine machines.

1. Refrigeration experience.

The heat transfer efficiency of fluorine refrigerant is higher than that of water and air, so the fluorine machine cools immediately and cools down quickly. The water machine has more water circulation heat exchange system than the fluorine machine, which belongs to the secondary heat exchange, and the heat capacity of the water is large, which means that there will be no rapid cooling, the air outlet is softer, and the comfort is high. The refrigeration (heat) carrier of the water machine is water, the air outlet is mild, and the indoor air moisture is not taken away during operation, which can keep the air moist and the human body feels more natural and comfortable.

2. Heating performance.

Henan Huiyin ** air conditioning installation, the common heating methods in winter mainly include air conditioning, radiators and floor heating, directly through the indoor heating experience of air conditioning without floor heating comfort, the main reason is that the hot air is light, the indoor wind disk is installed in a high place, and the human body is easy to produce a feeling of warm head and cold feet. The air conditioner can be directly connected to the end of the floor heating, and the compressor runs to absorb heat from the air and transfer it to the water to achieve floor heating. For families with high requirements for refrigeration and heating, you can consider the water machine, which is dual-purpose, and the heating operation is efficient and energy-saving, and the energy efficiency ratio can be achieved, so the heat production efficiency is extremely high, and the heating cost in winter is much lower than that of the wall-hung boiler.
