Reasons For The Air Conditioner Cooling Down

The split ac unit is one of the common air conditioning equipment that is used by many people due to its independent and suitable cooling capability. One of the common problems in using Split Ac Units is the decrease in the cooling power and cooling rate during the operation of the device, which occurs for different reasons, and in most cases, these problems can be easily solved.

In this article, we are going to examine the reason for the reduction of the coldness of air conditioners and splits from different aspects. Please stay with us until the end of the article.

The improper capacity of the Split Ac Unit and its coldness reduction

One of the main reasons for reducing the coldness of air conditioners and splits is choosing a capacity that is disproportionate to the desired space. The capacity of the Split Ac Unit means the cooling (and heating) power of the device, which is measured in Btu/hr units; The higher the number of BTUs your chosen device has, it means that the Split Ac Unit has more capacity and power to provide cooling of the environment.

Determining the capacity of the Split Ac Unit is done according to the cooling load of the intended space, and the most important factor in its calculation is the size of the place; Therefore, the capacity of the Split Ac Unit is selected according to the size of the environment. If the capacity is chosen less than necessary, that is, a cooler with a smaller capacity is installed in a larger space, it will reduce the coldness of the Split Ac Unit and also reduce the lifespan of the device due to long-term operation.

You can get in touch with the experts of the air conditioning unit of Damatajhiz specialized group and receive advice in order to supply a Split Ac Unit with a capacity suitable for your environment.

Leaking or reducing the refrigerant gas and reducing the coldness of the Split Ac

Refrigerant gas by flowing in the evaporator coils (internal panel) of the air conditioner and split absorbs the heat of the internal space and rejects it to the external space of the building through the condenser coils (external unit); Therefore, refrigerant gas plays an important role in air conditioners and splits, and if it runs out, the system's activity will be disrupted. Running out of refrigerant gas occurs for the following reasons:

Refrigerant gas pipe blockage
Refrigerant gas leak
Failure to control the charging of Split Ac Unit refrigerant gas

In order to check the existence of refrigerant gas leakage, the compressor of the device can be controlled; If the oil discharge from the compressor and the presence of oil stains are observed in it, it is possible to understand the leakage of refrigerant gas in the condenser of the device. Also, by using soap in the compressor of the Split Ac Unit and seeing the foam in it, you can also notice the leakage of refrigerant gas in the device or along the path of the connecting pipes.

In any case, it is recommended to contact authorized after-sales service centers of air conditioners and splits so that if there is a problem of leakage or running out of refrigerant gas, it will be fixed by authorized service personnel.

The inner panel filter is not clean and the coldness of the Split Ac Unit is reduced

The internal panel (evaporator) of the air conditioner and split have filters to absorb suspended particles and pollutants in the air. With the passage of time and the accumulation of these particles in the filters, especially in the air of the centers of big cities where there are more pollutants and suspended particles in the ambient air, the filters are blocked and prevent the flow of cool air from the evaporator to the desired environment and as a result, the cooling of the air conditioner is reduced. It is split.

Also, when the filter is blocked, the coils may become moldy and completely prevent airflow to the environment. In this regard, the filters should be periodically opened from the panel at least once every 3 months and completely cleaned with lukewarm water or even replaced if needed.

The effect of the installation location of the Split Ac Unit and reducing its coldness

The location of the internal and external panels of the Split Ac Unit has a significant impact on its performance and cooling rate. It is necessary to observe the following in order to prevent the coldness of the Split Ac Unit and its proper operation.

The distance between the two parts of the indoor and outdoor units must be according to the necessary standards for the device to function properly.
The outdoor unit should not be exposed to direct and continuous sunlight, and if there are no conditions for placing the outdoor panel in another space, it is better to use a canopy.
The installation location of the external panel should be such that the airflow from the condenser of the device is done well; Therefore, the necessary distances must be observed in all directions.

Split Ac Unit compressor failure and its coldness reduction

As you know, the engine compressor is the beating heart of the air conditioning system, and if it malfunctions, the entire system is disrupted; Because the compressor is responsible for compressing the refrigerant gas so that it flows in the evaporator coil and the process of cooling the environment is done; As a result, if this operation is not done correctly, the performance of the device will be reduced and the coldness of the Split Ac Unit will be reduced.

The failure of the compressor can be done for many reasons such as overload, faulty temperature sensor, electrical problems, etc.; Therefore, in the event of a problem, it is necessary to contact authorized after-sales service providers and specialists in Split Ac Unit repairs so that these issues can be resolved by authorized service personnel.

The coil is not clean and the cooling of the Split Ac Unit is reduced

One of the common reasons for the cooling of the Split Ac Unit is not cleaning the condenser coil. Since the condenser in the Split Ac Unit is responsible for removing heat from the refrigerant to the outside, and over time, dust, dirt, sediments, etc. accumulate on the surface of the coil, and if the condenser coil of the air conditioner is not clean, Split gas acts like an insulator and prevents its heat exchange with the external environment; In this way, the performance of the Split Ac Unit is reduced and its cooling rate is also reduced.

Therefore, in order to prevent this from happening, it is necessary to periodically clean the external condenser coil of the Split Ac Unit with air pressure.

Improper operation of the fan and reducing the coldness of the Split Ac Unit

Another common reason for the cooling of a Split Ac Unit is the blower fan's fault and its incorrect operation. The blower fan of the internal panel is one of the parts of the Split Ac Unit that transfers the cold (or hot) air produced to the indoor environment, and in the event of a malfunction, it is obvious that the flow of cool air will not be transferred well.

In some splits, the rotation of the fan is visible from the outside, in others, where the fan is not visible, it will be necessary to open the external body to control its operation so that if there is a problem, it can be fixed with the help of an expert repairman.

Failure of the thermostat and reduction of the coldness of the Split Ac Unit

The thermostat in the Split Ac Unit is responsible for controlling and balancing the temperature of the desired space, which it does by using the temperature sensor and disconnecting and connecting the compressor power. If the thermostat shows different temperatures in a short period of time, it indicates the failure of the Split Ac Unit thermostat and can cause the cooling of the air conditioner to decrease; For this reason, it is necessary to repair or replace the device's thermostat.

Of course, it should be noted that this problem may also be due to a problem with the electrical connections; Therefore, in order to solve the problem, an authorized and expert repairman should be contacted.
