The air conditioner is hot in thick pipes, cool in thin pipes, and not cool

The thin tube of the air conditioner is cool, but the thick pipe is not cool, which is obviously a lack of refrigerant.

First of all, to ensure that the indoor and outdoor units are clean and well ventilated, which is also the most basic condition to ensure the normal operation of the air conditioner, including the clean indoor filter and outdoor fins. Depending on usage, it is recommended to wash at least 2 times a year.

Secondly, the air conditioner is not good or not refrigerated, it is not necessarily a lack of refrigerant, in the case of the quality of the air conditioner is not in place, the air conditioner will not lack refrigerant if it exceeds the design life.

As a non-professional, how to simply judge whether the air conditioner lacks refrigerant, observe and touch the frost and temperature of the high and low pressure valves of the outdoor unit.

1. Under normal circumstances, the high-pressure valve is dry and has a certain residual temperature (there will be a small amount of condensate in the refrigeration state when working for a long time), and the low-pressure valve is moist and has water dew, and the amount of water dew depends on the weather conditions.

2. The high-pressure valve is dry (there will be a small amount of condensate in the refrigeration state when working for a long time), and the low-pressure valve is frosty, which is a lack of refrigerant.

3. The high-pressure valve is frosty, and the low-pressure valve is also frosted or dry, which is a serious lack of refrigerant or micro-blockage of the system.

4. The high-pressure valve is not cool when it is dry, and the low-pressure valve is not cool when it is dry, which is a serious leakage of the system or the compressor is not working.

Because the heating and refrigeration of the air conditioner are opposite, that is to say, the external unit of the air conditioner is the condenser and the internal unit is the evaporator when the air conditioner is refrigerated. When heating, the outer machine is an evaporator, and the inner machine is a condenser.

As for the cold tube, it is caused by the lack of refrigerant or the outdoor temperature is too low to dissipate the cold energy from the evaporator.

First of all, you should clean the outer fins, and then see if you return to the tube to warm your hands, if it is still cold, then there is less refrigerant, add it.

Ask. The air conditioning was clean in all parts. Although it is very cold in winter, the thick pipe is the exhaust pipe during heating, and it is hot, indicating that the outdoor unit has the ability to extract sufficient heat, but the thin pipe that returns from the indoor unit is cold, and the thin pipe of the air conditioner working under normal heating conditions should be warm, and the wind blown out of the indoor unit is almost not hot, all must be the refrigerant circulating very slowly in the indoor unit, please advise, the reason for the slow circulation is more or less refrigerant, or is there a dirty blockage?

I have added some refrigerant to the temperature probe of the indoor unit to heat the forced refrigeration, and the pressure is low when the refrigeration is working, and the pressure is balanced when the air conditioner is shut down.

Dizzy. It is less snow seed, and the normal air conditioner factory is refrigeration and low pressure, which is obviously not enough pressure.

Another problem is that the refrigerant is very affected by temperature.

It is recommended that you add refrigerant, feel the addition with your hands, and look at the current at the same time, so as not to overcurrent.

What is the reason why the thin pipe of the air conditioner is cold, and the thick pipe is not cold.

Hello, I'm here to help you solve this problem. Kissing may be due to the following reasons caused by the failure of your Volt race, 1One is that the air conditioning wind speed is too low, 2

The second is that the ambient temperature is too low, 3The third is that the room area is too large, 4Fourth, the refrigerant is insufficient, and you can check it and prepare it.

The above is all my reply, I hope it can help you, I wish you a happy life

Summary. When the air conditioner is refrigerated, the thin pipe is hot and the thick pipe is cool, what is the reason for the poor refrigeration effect, hello, in the case, if it is a normal air conditioner, after turning on the air conditioner, in this case, the thin pipe of the air conditioner is usually colder than the thick pipe, this situation often happens, when the machine is just turned on, at this time the air conditioner has not lowered the indoor temperature, after the indoor temperature is lowered, the thick pipe will be cooler than the thin tube, but the thin pipe will not be hot, so what is going on with the air conditioning refrigeration thin tube is hot and the thick pipe is cold? Taking Haier air conditioner KFR-72LW 07PAQ83TU1 as an example, the reason why the thin pipe of air conditioning refrigeration is hot and the thick pipe is cold, it may be that the outdoor unit of the air conditioner is too dirty, and the exhaust temperature of the air conditioner is relatively high.

It may also be that the air conditioner has added too much fluorine, if it is a thin pipe of the indoor unit, such as some vertical cabinet air conditioners, the throttling device will be designed in the indoor unit, and the thin pipe will be hotter. Hope mine is helpful to you, thank you and have a great day! <>

There are five pressures under <> refrigeration, whether more or less.

Cabinet machine 2 hp. Dear, you are grinding well, the pressure is about to be loaded, and the shed should not be judged to be higher than 6 pressures. For household air conditioners, it is indeed a foreign practice to measure it with "horse".

The "horse" chain here refers to the input power. Hope mine is helpful to you, thank you and have a great day! <>

1. It may be that the freon in the air conditioner is not enough, so the thin pipe of the air conditioner is not as cool as the thick pipe. 2. It is also possible that there is a lack of refrigerant, so that the air conditioner cannot operate normally when it is running. Suggested Treatment:

1. If you have spare freon at home or you will add freon, you can add it directly, the operation method is very simple, first unscrew the filling port of the air conditioner, and then connect the freon line, and then open the valve, inject the prepared freon into it, be sure to observe the watch hand when injecting, as long as you point to it when you can turn it off, in the whole process of operation you must be hospitalized safely, disconnect the power supply of the old store of the whole shed, and avoid all kinds of fire sources, Then start working, if it is a high-level person, do not blindly untie the chain by yourself, be sure to hire professional personnel, and then do a good job of safety measures, remember to be careful. 2. You can do a full range of cleaning work for your own air conditioner, because no matter what kind of mechanical equipment, if you don't clean it for a long time, it will accumulate a lot of dust, so that there will be various problems when you run it, if you usually maintain them regularly and keep them clean, then their performance will become better, which will also reduce their aging problems.

Hello: The thin tube of the air conditioner is cool, and the thick pipe is not cool, which is obviously a lack of refrigerant.

First of all, to ensure that the indoor and outdoor units are clean and the ventilation is smooth, which is also the most basic condition to ensure the normal operation of the air conditioner, including the indoor filter screen and the outdoor posture section of the machine fins are clean. Depending on usage, it is recommended to wash at least 2 times a year.

Secondly, the air conditioner is not good or not refrigerated, it does not necessarily mean that there is a lack of refrigerant, and when the air conditioner is installed in place, the air conditioner will not lack refrigerant if it exceeds the design life.

In general, the two ends of the automobile compression machine, the thick is the low-pressure pipe, the thin is the high-pressure pipe, under normal circumstances, the low-pressure seepage and dismantling pipe temperature is low, and the temperature of the high-pressure pipe is high. Otherwise, it means that the efficiency of the compressor has become faster and worse.
