The 7.5°C Thermal Management PCM Can Be Used For More Efficient Operation Of The Air Conditioning System

Composition and structure:

• 7.5°C Thermal Management PCM typically consists of a suitable phase change material that undergoes a phase transition at around 7.5°C. Common phase change substances may include some organic compounds or inorganic salt hydrates, etc.
• Its structure is generally to maintain the stability and availability of phase change materials through encapsulation and other means.
• For example, it is possible to encapsulate the phase change material in a microcapsule, which is usually made of a polymer material, which prevents the leakage of the phase change material and allows it to bond well with other components in the air conditioning system.

Performance characteristics in air conditioning:

1. Accuracy of temperature regulation

• When the temperature in the air conditioning system approaches 7.5°C, the PCM starts to undergo a phase change. During the phase change, it is able to absorb or release large amounts of heat, allowing the air conditioning system to control the temperature more precisely.
• For example, when the air conditioner needs to cool down, the PCM absorbs heat at around 7.5°C, which helps to quickly reduce the temperature of the surrounding air, and because the temperature is relatively stable during the phase change, it can avoid excessive temperature drops or fluctuations, and improve the temperature control accuracy of the air conditioner.

2. Energy storage and release

• PCM stores energy when the temperature is right and releases it when the air conditioning system needs to adjust the temperature. For example, at night or when the air conditioning load is low, when the ambient temperature reaches around 7.5°C, the PCM can store excess cooling capacity.
• During the day or when the air conditioning load is high, it can release the stored cooling capacity, reduce the running time and load of the air conditioning compressor, and thus achieve the purpose of energy saving.

3. Stability and reliability

• During the operation of the air conditioning system, the PCM is able to withstand multiple phase change cycles to maintain stable performance. The encapsulated structure also ensures that phase change substances do not leak or deteriorate, ensuring long-term reliable operation of the air conditioning system.
• At the same time, the chemical properties of PCM are relatively stable, and it is not easy to react adversely with other components in the air conditioning system.

4. Energy saving and efficiency increase

• By taking advantage of PCM's phase change characteristics for thermal management, air conditioning systems can operate more efficiently. It can reduce the frequent start and stop of the air conditioning system and reduce energy consumption.
• According to research, the reasonable application of PCM in the air conditioning system can achieve about 10% - 30% energy saving effect, the specific energy saving effect varies depending on the type of air conditioning system, the use environment and other factors.

How it is applied in air conditioning:

1. Improvement of air conditioning heat exchanger

• PCM can be integrated into the heat exchanger of an air conditioner. For example, a coating containing PCM is applied to the surface of an evaporator or condenser, or PCM is encapsulated in the ducts of a heat exchanger.
• When the air conditioner is running, the phase change process of PCM at about 7.5°C can assist the heat exchanger for heat exchange and improve the heat exchange efficiency. In refrigeration mode, when the refrigerant temperature is reduced to close to 7.5°C, the PCM absorbs heat and enhances the cooling effect of the evaporator; In heating mode, the PCM releases heat to improve the heating efficiency of the condenser.

2. Application of air duct system for air conditioning

• A heat storage device containing PCM is installed in the air duct of the air conditioner. As air flows through the air duct, the PCM can absorb or release heat in response to changes in air temperature, adjusting the temperature and humidity of the air.
• For example, in summer, when the air temperature is above 7.5°C, the PCM absorbs the heat and lowers the air temperature; In winter, when the air temperature drops below 7.5°C, the PCM releases heat, raising the air temperature, which improves the overall energy efficiency and comfort of the air conditioning system.

3. Optimization of indoor unit of air conditioner

• In air conditioning indoor units, PCM can be applied to air filtration units or fan components, for example. For example, adding PCM to an air filter can regulate the air temperature as the air passes through the filter, while also serving as it purifies the air.
• The use of PCM in wind turbine components reduces the amount of heat generated during the operation of the wind turbine and increases the efficiency and longevity of the turbine.
