One to five have room refrigeration, and some rooms are not refrigerated, what is the reason?

A one-in-five air conditioning system means that one outdoor unit is connected to five indoor units, which can achieve synchronous cooling or heating. If some rooms are cooled and some rooms are not, there may be the following reasons:

1.Outdoor unit failure: If the outdoor unit fails, then the air conditioning effect in all rooms will be affected.

2.Indoor unit failure: If an indoor unit fails, the air conditioning effect of that room will be affected, but the air conditioning effect of other rooms will not be affected.

3.Air conditioning duct problems: If the air conditioning duct is damaged, leaking, clogged, etc., it will affect the transmission of air conditioning effect.

4.Clogged air conditioner filter: If the air conditioner filter is blocked, it will affect the circulation of air, which will affect the air conditioning effect.

5.Room door crack problem: If the room door crack is too large or too small, it will affect the air conditioning effect.

Therefore, it is necessary to investigate the above causes one by one and take corresponding maintenance or cleaning measures to restore the normal use effect of the air conditioner.

The indoor units of the air conditioner are set incorrectly or there are some abnormal conditions in the air conditioning system.

Generally speaking, as long as there is an indoor unit that can be used normally, all indoor units can be used normally.

However, the occurrence of the described phenomenon under certain special conditions is not excluded.

It is recommended to measure multiple critical state parameters during the operation of the refrigeration system at the same time, and judge the fault and find the corresponding solution according to the changes of these key state parameters.

What is the reason why some of the rooms are refrigerated and some are not? Because the space is too big, some room coolers are all to that room, some rooms don't hear the heating, so he arranges, and some air conditioners go to that room, he will be very cold, so I want to eat a lot of space, so it is best to say that the space is smaller, it will be cooled better.

What are the reasons why Haier air conditioners do not refrigerate - not enough refrigerant.

When the air conditioner is used for three to four years, the cooling effect of the air conditioner is not good enough, the reason may be that the air conditioner refrigerant freon has volatilized for a long time, or these may lead to insufficient refrigerant, resulting in poor cooling effect of the air conditioner, or no refrigeration. The solution is very simple, and it can be solved by adding freon.

What are the reasons why the air conditioner does not cool – the voltage in the home is unstable.

In the summer of electricity tension, the power supply voltage is often unstable, when the normal voltage is not reached, it may lead to poor refrigeration effect of household appliances air conditioning or no refrigeration, this problem can not be solved by air conditioning maintenance technicians, either to ensure the normal power supply voltage, or to choose inverter air conditioning.

1. The freon in the air conditioner is not enough, which generally occurs in the air conditioner that has been used for more than one year. The freon function in the air conditioner is refrigeration, and if the air conditioner is used for a long time, the air conditioner will lack fluorine, and the external manifestations are not refrigeration, water leakage, shutdown, etc.

2. The air conditioner receiver is bad or the battery in the air conditioner remote control is dead, but you don't find it, then you turn it on, but it strikes, or sometimes it is refrigerated and sometimes it is not refrigerated.

3. When the voltage at home is unstable, it will directly affect the work of the air conditioner.

4. There is a dust filter in the air conditioner, which is to prevent the entry of dust and protect the air conditioner. Some customers have used the air conditioner for a long time, but they don't know how to clean it and maintain it, resulting in excessive dust accumulation, affecting the heat dissipation of the air conditioner, and it is difficult to refrigerate.

5. It's obviously turned on, but it doesn't move, or you let it wind left and right, but it goes up and down. This phenomenon is generally caused by the failure of the control panel of the internal and external units of the air conditioner.

1. Check whether it is the lack of freon, and if so, add a little freon to the air conditioner immediately. However, supplementing Freon requires professional staff, so remind everyone not to do it yourself.

2. Check whether the voltage at home is stable and whether the remote control of the air conditioner has electricity, and replace the battery with a new one if there is no power. If the voltage is not stable, we have to buy a voltage regulator to stabilize the voltage.

3. Regularly clean the indoor and outdoor units of the air conditioner. It is recommended that you buy a bottle of detergent specially designed to clean the filter, which can quickly dissolve the dust on it, rinse it and dry it.

There is a room that is not refrigerated, which can only indicate that he is a signal communication problem, there are four air conditioners that are refrigerated, and only one is not refrigerated, which means that the communication is not in place.

Focus on checking the connection lines of the internal and external units, because it cannot be a problem of lack of refrigerant, if there is a lack of refrigerators, the other four will not be refrigerated.

Daikin air conditioning after-sales personnel were later detected due to the damage of the indoor and outdoor temperature transmitters, first of all, the other tuyeres of the internal unit are working normally, and this is not normal, the air conditioning host is definitely no problem, it should be the problem of the indoor unit tuyere, after testing on the 10k sensor, troubleshooting.

This problem often occurs in household ** air conditioners, and it is best to find after-sales maintenance.

If the machine is not out of warranty, it is better to contact customer service for maintenance.

This situation first troubleshoots the host, and there are several scenarios:

1: The dust cover in this room is too dirty.

2: If it is a water-cooled unit, is there a valve that is closed, or the indoor unit in this room does not discharge water and drain the vacuum, resulting in poor water flow.

3: If the water cooling unit is not dirty and blocked, the filter screen of the room system is blocked, which causes the flow to be intercepted. "The filter is generally on the water inlet pipe above the air conditioner".

4: If it is a refrigerant, is it that the copper pipe is blocked by the welding liquid during welding?

Myth 1: The refrigerant needs to be changed once a yearMany users feel that the air conditioner must be replaced after being used for a period of time, but this view is not correct. The claim that air conditioners need to be changed regularly is pure nonsense.

Like a refrigerator, an air conditioner is cooled by a refrigerant, but since the refrigerator is a closed refrigeration device, it never needs to add refrigerant. The refrigeration system of the air conditioner is semi-closed, and there is generally some leakage of refrigerant during the refrigeration process, so sometimes it needs to add refrigerant.

However, the leakage of refrigerant is different for each air conditioner, so there is no specific time for the user to replace it. In fact, air conditioners that have been used for four or five years without adding refrigerants abound.

The current of the air conditioner. Pressure within the system. The temperature difference between the air inlet and the air outlet.

Before adding refrigerant, professional maintenance personnel will first look for leaks in the air conditioner. If the refrigerant needs to be added, the air conditioner must have refrigerant leakage. Even if the refrigerant is added, it is added in vain without looking for a leak, because the refrigerant will quickly re-leak the light.

Myth 2: If the refrigeration effect is poor, refrigerant needs to be added, and too little and too much refrigerant in the air conditioner will affect the refrigeration effect of the air conditioner. In addition, there are many factors that will affect the cooling effect, such as the mismatch between the space size of the room and the number of air conditioners.

Power line issues.

Fault phenomenon: no refrigeration.

Reason analysis: power on, the internal machine works normally, observe the external machine, the press starts the "hum" sound, can not start normally, the voltage is reduced from 230 volts to 138 volts, the press is protected, the power supply is identified as a problem, check the user's power socket, and find that the decorator uses the grounding wire as the zero line, and the test machine is normal after processing.

Solution: Connect the ground wire with the neutral wire.

Experience summary: installation must be terminated with n neutral wire, can not be replaced by grounding wire, ground wire and neutral wire reversed, but also may cause air switch tripping, new installation of this problem to focus on checking the power supply, sometimes the power cord is too thin, the air conditioner starts when the current is large, and the large voltage drop on the wire will also cause difficulty in starting. In addition to power cord issues, the size of the air switch often causes start-up trips.

What are the reasons why an air conditioner is not cooling?

This is because the pipes are clogged or because the air conditioner is turned on too much in other rooms, so the back room will not cool well, or even not cool.

First of all, it may be because the room is too large, and the weather is relatively hot, and the refrigeration effect is not obvious, and secondly, it is possible that the air conditioner has not been cleaned for a long time, and the air outlet is blocked by dust, etc., and there may be that the air conditioner needs to be fluoridated.

It may be that the vent in the room is blocked, pay attention to check, or it is possible that the air leakage in this room is more serious.

It may be that there is air in the system, or that the extension coil fins are too dirty.

The air conditioning motor in this room does not work.

For more details, please ask someone from the maintenance department to take a look.

1. The reason for insufficient cooling fluorine.

A common reason why an aircon is not cooling is that there is not enough fluoride in the aircon. After the old air conditioner is used for a long time, the freon in it will volatilize, but it may be that the freon in the air conditioner is leaking. If fluoride is not available, it can be replenished in time.

2. The reason for the power supply (refers to the amount of work completed per unit time).

The second reason why the air conditioner is not cooling could be that the power of the air conditioner (the amount of work done by the object in a unit of time) does not match the size of the room. Xi'an Daikin Air Conditioner Repair** is designed to save space (usually sealed) and provide space to handle changes in air temperature. Its function is to regulate the temperature (or enclosed space, zone), humidity, cleanliness and air flow of the air in the room to meet the requirements of human comfort or process, but the size of the air conditioner is chosen according to the space.

Size. In this case (condition), air conditioning and utility areas need to be matched, and practical indoor heat sources should be minimized. For example, when the air conditioner is turned on, all doors and windows need to be closed.

3. The reason for insufficient voltage.

Since the voltage required for the air conditioner to start is relatively high, and there are many households that use the air conditioner in summer, the household voltage is likely to be unstable (wìndìng), resulting in the air conditioner not being able to cool down. Xi'an Daikin Air Conditioning After-sales ServiceModern technology development sometimes requires adjustment and control of air pressure, composition, odor and noise, etc. Therefore, the task of air conditioning is to use technical means to create and maintain an air environment that meets specific requirements.

4. The ventilation pipe is too long in the room.

The distance between the outside air conditioner and the indoor air conditioner also has an impact on the cooling effect of the air conditioner. It is best to measure the indoor and outdoor installation locations before purchasing. The indoor unit is connected to the outdoor unit as a ventilation duct.

If the location of the air conditioner is not properly installed, resulting in the ventilation duct being too long, the heat transfer of the air conditioner is slow. The cooling efficiency is also very low.

5. The maintenance reason is not in place.

Many air conditioners are not cooled because they neglect the cleaning and maintenance of the air conditioner. Xi'an Daikin Air Conditioner Repair** is designed to save space (usually sealed) and provide space to handle changes in air temperature. Its function is to regulate the temperature (or enclosed space, zone), humidity, cleanliness and air flow of the air in the room to meet the requirements of human comfort or process, but the size of the air conditioner is chosen according to the space.

Size. After using the air conditioner for a period of time, it is necessary to clean the body housing, filter and condenser (category: heat exchange equipment) and evaporator.

There are many reasons why the air conditioner is not refrigerated, and it is necessary to ask professional personnel to answer it, so that it is targeted.

See if the three pipes are too long, whether the temperature adjustment is too high, if not the reason for the adjustment, you should contact customer service to deal with it.

It should be a problem with the compressor, our home is also Hitachi's air conditioner, each of which is a separate compressor for separate refrigeration, if there is no refrigeration, it is only possible that there is a problem with the compressor, it is recommended that you call customer service to repair it for you.

Answer 1: It may be that the electronic components or programs of the host are faulty, resulting in the wrong transportation of the air-conditioner, and there is no air-conditioning in a single room, and there is no refrigeration in a single room. This situation should only be handled by a maintenance professional.

2. It may be that the filter screen of the room system is too dusty and dirty, and the air conditioner cannot be transported normally, resulting in a single room not being refrigerated. The air conditioning exhaust holes in this room can be cleaned and maintained, and if the fuselage housing, filter and condenser need to be cleaned, they can be cleaned and maintained.

3. It may be that there are errors and inadequacies in the installation of the air conditioner, the ventilation pipe is too long, the position of the air conditioner is unreasonably installed, the heat transfer of the air conditioner is very slow, the cooling efficiency is also very low, and it is difficult to feel the temperature change in individual rooms. The ducts of the air conditioner can be reinstalled or the air conditioner can be adjusted.

4. It may be that the valve of the water-cooled unit of the ** air conditioner is closed, resulting in the indoor unit of the individual room not discharging water and vacuum, resulting in poor water flow. The valve can be opened and the drain channel cleaned for restoration.

Summary. Hello,

There are several reasons for this:

There is a problem with the installation of this room and the ceiling, which means that the ceiling blocks the air outlet or return air outlet of the air conditioner;

There is a problem with the installation of the air conditioner, the pipe in this room is too long, it is usually recommended that a single pipe should not exceed 20 meters, or there is a problem with the pipe in this room, resulting in less refrigerant in the copper pipe entering the room;

Design problems, the design of the host is small (note, this is allowed, the power of the host is smaller than the power of all indoor units is called overmatching, the premise of permission is that all indoor units are not turned on at the same time), but the actual situation of your home is that all indoor machines are turned on at the same time, and the situation of opening at the same time will lead to poor cooling (thermal) effect in a certain room, or no effect. Generally, this situation is mostly due to air conditioning installation problems. That is, the second kind of problem.

Check whether the air conditioner is running normally, including the inspection of the indoor unit and the outdoor unit, especially the compressor of the outdoor unit, if one of them is not running normally, then you have to ask the master to repair it. There is also a check on the filter of the air conditioner to see if the filter is blocked by too much dust.

**Why is the air conditioner cool in one house and not cool in one house, and what is the reason.

Hello, there are many reasons: there is a problem with the installation of this room and the ceiling, which means that the ceiling blocks the air outlet or return air outlet of the air conditioner; If there is a problem with the installation of the air conditioner, the pipeline in this room is too long, and it is usually recommended that a single pipe should not exceed 20 meters, or there is a problem with the pipe in this room, resulting in less refrigerant in the copper pipe entering the room; Design problems, the design of the help and beam host with a small (note, this is allowed, the host power is less than all the indoor unit power is called overmatching, the premise of permission is that all indoor units are not opened at the same time), but the actual situation of your home is that all indoor opportunities are opened at the same time, and the situation of opening at the same time will lead to poor cooling (heating) effect in a certain room, or no effect. Generally, this situation is mostly due to air conditioning installation problems.

That is, the second problem is to check whether the air conditioner is operating normally, including the inspection of the indoor unit and the outdoor unit, especially the compressor of the outdoor unit, if one is not running normally, then you have to ask the master to repair it. There is also a check on the filter of the air conditioner to see if the filter is blocked by too much dust.
