Dr. Chunlanjing: What should I do if the air conditioner is not refrigerated and does not heat

Dr. Chunlanjing air conditioner is Chunlan's hang-up product after 2000, and there are several possibilities for refrigeration without heating:

1. Single cooler. This type of product will definitely not make heat.

2. You may be in too much of a hurry. When heating, the unit has anti-cold wind protection, and the external unit will work for more than three minutes, and the internal machine will start, and there is no sound before the internal machine starts. After you have to drive it for a while, see if the internal machine is still not working.

3. The reversing valve is broken, and the machine cannot enter the heating operation. In this case, after the heating is turned on, there is really no sound, and you have to find a professional to repair it.

4. Other electrical faults may also lead to the normal operation of heating. This situation can only be handled by professionals.

Hello! I hope mine satisfies you!

Air conditioning for five horses! The room was huge. The refrigeration area is larger than the heating, so the heating effect is not good and normal, you must be commercial, you must only count the refrigeration area when you buy an air conditioner, and do not consider the heating well, the commercial roof is very high from the ground, and the heat is light up, so your heating is definitely not good!

If there is nothing wrong with your machine, only this one explains, and finally I wish you a happy life!

Find it in the know: Beijing Chunlan air conditioning after-sales maintenance. What is the reason for the consultation consultation, it is also possible that you have not opened it well.

Something is out of order, is there a warranty? If you are still in warranty, it is recommended that you report for repair directly.

Summary. First of all, see if your air conditioner model has a heating function, and some models do not have heating.

If there is a heating function, but it can't be heated, you should go directly to the repair. There are many reasons, and I will briefly mention a few: (1) the four-way reversing valve cannot be switched; (2) There is a problem with the circuit of the air conditioning control board and cannot be controlled; There is a temporary solution, the air conditioner has a forced start, you try to force the start, without remote control.

Chunlan air conditioner does not heat what's going on, there is no problem with refrigeration.

It is also possible that the air conditioner is short of fluoride.

A few days ago, it was fine, but suddenly the heating was not made, the refrigerant has been added, but the heating is not ideal.

Added. Is the air conditioner still in good condition?

The warranty period has expired. Hello, the aging of the air conditioner is also one of the reasons for not heating, it is recommended that you find a professional air conditioner master to check it for you.

What to do if the <> Chunlan air conditioner is not hot: 1. Use cloth curtains and spray-painted portrait partitions to reduce the room area. 2. Every half a month, clean the filter of the air conditioner room.

3. When using air conditioners, use heaters or heaters at the same time. 4. When the fixed-speed air conditioner is heating, the auxiliary electric heating is turned on at the same time. 5. If the air conditioner is suspected of being short of fluoride, please let the service staff check the fluoride after the sale.

This answer applies to most of the air conditioner models of the Chunlan brand.

<> reasons why Chunlan KFR-35GW VEAD-E2 air conditioner does not refrigerate: 1. Too little refrigerant or leakage; 2. The compressor is damaged; 3.

This answer applies to most models of the Chunlan brand.

Chunlan air conditioner only heats and does not refrigerate, and after after-sales maintenance, it becomes only refrigeration and no heating, what's going on?

Chunlan air conditioning is still very good, this is a non-Chang stool often famous air conditioning products, sales in the limb travel market sales is very high, Chunlan air conditioning quality is very good, it is also very convenient to use, but some Chunlan air conditioners sometimes only refrigeration and not heating, the specific reasons are: 1. Poor contact or damage to the refrigeration motor switch. 2. The refrigerant of the air conditioner is insufficient, resulting in the air conditioner being unable to be used normally, and the refrigerant needs to be added.

3. The temperature difference between indoor and outdoor is too large, and the air conditioner is not refrigerated due to the high temperature. 4. The air-conditioning compressor is damaged. This is the reason why Chunlan air conditioner only heats and does not refrigerate, you can learn about it.

Hello, Chunlan air conditioner heating does not respond: Chunlan air conditioner heating may not work because of the air conditioner model problem, and some air conditioners cannot be heated. Causes and solutions of heating failure; 1. The thermostat of the indoor unit is damaged, and the air conditioner is not cold and warm.

Some air conditioners can be refrigerated and heated, and some air conditioners can only be refrigerated, look at the nameplate on the indoor unit of the air conditioner is KF or KFP, if it is KF certification coarse air conditioner can only refrigerate, it is recommended to replace the air conditioner as needed. 2. If the machine fails and the thermostat of the indoor unit is damaged, it is recommended to find a professional for repair. 3. The outdoor temperature is too low.

If the outdoor temperature is too low, the air conditioner will be frosted frequently, and then there will be no heating, so it is recommended to use a tool to clean the frost on the air conditioner to solve the problem of the air conditioner not heating. 4. Air leakage from the four-way valve of the air conditioner. It is recommended to replace the four-way valve to solve the problem of air conditioning not heating.

5. Lack of fluoride in the air conditioner. Generally speaking, more fluorine is used in air conditioning heating than in refrigeration, so it is recommended to add fluoride appropriately to solve the situation that air conditioning does not heat. Extended Information; Air conditioner fluoride is fluorinated by means of a high-pressure process pipe on the compressor Specific steps:

1. Connect the puncture valve, the three-way maintenance valve and the fluorine bottle, and discharge the air in the connecting pipe. 2. Use a pressure gauge to measure and write down the saturation pressure value of the fluorine in the fluorine bottle at the current ambient temperature for future reference. 3. In the state of air conditioning shutdown, first put the stabbing valve into the filter process pipe, rotate the handle to penetrate the outer wall of the process pipe, then unscrew the fluorine bottle, three-way maintenance valve and stabbing valve, add a small amount of fluorine to the fluorine bottle upside down (control the amount of fluorine is the same as above), and then close the three-way maintenance valve.

4. Start the machine for 10 minutes, and then observe the pressure value (high pressure pressure) of the pressure gauge on the three-way maintenance valve, if it meets the value shown in the attached table, that is, at the current ambient temperature, the saturation pressure (gauge pressure value) of the fluorine in the fluorine bottle corresponds to the pressure value (high pressure pressure) of the pressure gauge when the machine is turned on, which means that the fluoride is accurate. For example, if the ambient temperature is 3, the saturation pressure of the fluorine in the fluorine bottle is 1 19MPa, and the corresponding high pressure pressure is 1 grinding and macro 67MPa, it means that the fluoride is accurate.

Precautions: pay attention to the fluoride when adding, when you start to add, you need to turn the fluorine bottle upside down, the time of one inversion should not be too long, and the cold air temperature of the pressure gauge and air conditioner should be observed at all times, so as not to cause negative effects due to excessive fluoride at one time.

Chunlan air conditioning heating does not react: 1. Improper use environment and use method: do not switch on and off the air conditioner frequently, if an air conditioner is switched on and off frequently, it will have an impact on the life of the air conditioner, and it will also affect its heating effect.

Turning off the air conditioner is easy to cause excessive starting current and burn the fuse, which is also a damage to the motor of the air conditioner, which may cause the motor to burn out, and then affect the heating function of the air conditioner. 2. The filter screen becomes dirty: the filter screen of the air conditioner is the component that can accumulate dust the most, it is recommended to clean the filter once after two weeks, and the filter screen is not cleaned for a long time, which will cause the filter to be blocked, reduce the filtration capacity, and then reduce the amount of air circulation, thereby affecting the heating effect.

Therefore, it is necessary to clean the filter frequently, do not touch the metal part of the indoor unit when disassembling the filter, be careful to be scratched by the metal, wipe the dust with a dry cloth, and if the filter is too dirty, you can wash it with clean water, but do not wash it with hot water, if the water is too hot, it may cause the filter to deform, after cleaning, dry naturally in a cool place, do not expose it to the sun. 3. The condenser and evaporator are too dirty: in the components of the air conditioner, the heat sink of the condenser and evaporator should be protected, if the condensation fails the device and the evaporator is too dusty, it will also reduce the heat exchange effect, resulting in insufficient heating capacity of the air conditioner.

For the protection of the heat sink, be more careful, remove the dust from the cooler every three months, and do not touch the heat sink easily. The movement can be dismantled every year, the motor bearings should be filled with appropriate lubricating oil, and the dirt on the surface of the refrigeration system should be removed. This answer is applicable to Chunlan KFR-25GW VEAD-E2 and Chunlan KFR-35GW RCBPDWA-E3 brand air conditioner models.
