Plate heat exchangers, with their efficient energy recovery mechanism, can transfer heat or cold during the exchange process between exhaust and fresh air. According to actual data statistics, after installing plate heat exchangers, the energy consumption of air conditioning systems in shopping malls can be reduced by 20% -30%, greatly reducing electricity and fuel consumption, lowering operating costs, and responding to the national call for energy conservation and emission reduction, helping to achieve the "dual carbon" goal.
The necessity of heat exchangers in large shopping malls
The mall is densely populated, with obvious heat and moisture dissipation from the human body, and the display area of goods is prone to produce odors. If the ventilation system only provides simple air exchange, it is difficult to ensure the temperature and humidity balance between fresh air and indoor air. Plate heat exchangers can perform pre cooling or preheating treatment on fresh air, making the temperature of the fresh air close to the indoor temperature and avoiding discomfort for customers and employees caused by overcooling or overheating of the fresh air. At the same time, continuous and stable ventilation combined with efficient heat exchange can quickly remove indoor polluted air and odors, always keeping the air fresh, creating a comfortable shopping environment for customers, extending their stay time, and also creating good working conditions for employees, improving work efficiency.
The impact of heat exchangers on batteries
Preventing battery overheating: Excessive temperature can accelerate chemical reactions inside the battery, leading to capacity degradation and shortened lifespan. The heat exchanger indirectly prevents the battery from overheating during charging by cooling the charging pile. For example, when the ambient temperature is high or fast charging is performed, the heat generated by the charging pile is relatively high. The heat exchanger can effectively reduce the temperature of the charging current and voltage, reduce the heat conducted to the battery, and keep the battery charging within the appropriate temperature range, thereby extending the battery life.
Reduce the loss of chemical substances inside the battery: Excessive temperature can cause the electrolyte inside the battery to evaporate, electrode materials to age, and reduce the performance and lifespan of the battery. The heat exchanger controls the temperature of the charging environment, which helps to slow down the rate of chemical loss inside the battery, maintain the chemical balance inside the battery, extend the cycle life of the battery, and reduce the cost and frequency of battery replacement due to premature aging.
Does the heat exchanger affect the charging efficiency？
Heat exchangers play a crucial role in electric vehicle charging stations, as they control the temperature during the charging process and have a significant impact on charging efficiency and battery life, as follows:
The impact on charging efficiency
Optimize charging power: When charging electric vehicles, the power electronic components of the charging station generate heat. If the heat is not dissipated in a timely manner, the temperature of the components will rise, which will lead to a decrease in their performance and even trigger the overheating protection mechanism, reducing the charging power. The heat exchanger can effectively dissipate this heat, keeping the power electronic components within a suitable operating temperature range, ensuring that the charging station always charges the electric vehicle at a high power, shortening the charging time, and improving charging efficiency.
Stable charging voltage and current: Temperature fluctuations can affect the stability of the output voltage and current of the charging station. The heat exchanger maintains stable internal temperature of the charging station, which helps to ensure the accuracy of output voltage and current, making the charging process smoother. Stable voltage and current can make the battery management system of electric vehicles work more efficiently, improve charging efficiency, and avoid charging interruptions or efficiency reductions caused by voltage and current fluctuations.
Cooling method for solar inverters
Air cooling: Air cooling is a common cooling method. The air-cooled heat exchanger we produce has good heat dissipation effect and can adapt to inverters of different powers. We can design the number, position, and speed of fans for you based on the heating situation of the inverter, in order to achieve efficient heat dissipation.
Liquid cooling: For high-power solar inverters, liquid cooling is more suitable. Liquid cooling systems typically consist of cooling pipes, coolant pumps, radiators, and other components. The coolant circulates in the cooling pipes inside the inverter, absorbing heat and dissipating it to the outside through the radiator. Our liquid cooled heat exchanger has the advantages of high heat dissipation efficiency, precise temperature control, and low noise.
How does the heat exchanger function in the mushroom cultivation workshop
Mushroom cultivation and ventilationHeat exchangers have various important uses in the edible mushroom cultivation industry. Heat exchangers can be used to optimize the ventilation system of mushroom cultivation workshops, accurately control the temperature and humidity of the air entering the workshop, provide a stable and suitable environment for the growth of edible mushrooms, and improve the yield and quality of edible mushrooms.
1. Control the cultivation temperature: The temperature of the cultivation environment can be precisely adjusted through a heat exchanger, providing stable and suitable temperature conditions for the growth of mycelium, promoting rapid and robust growth of mycelium, and shortening the cultivation period.
2. Adjust air humidity: Edible fungi require suitable air humidity for growth, generally around 85% -95%. Heat exchangers can be used in conjunction with air handling systems to regulate the humidity of the air by heating or cooling it. When the humidity is low, heat the air to contain more water vapor, and then increase the air humidity by spraying water or other methods; When the humidity is high, cooling the air can condense water vapor, reduce air humidity, and create a suitable humidity environment for the growth of edible fungi.
3. Optimize the ventilation system: Good ventilation is required during the cultivation process to provide sufficient oxygen and exhaust gases such as carbon dioxide. The heat exchanger can preheat or pre cool the fresh air entering the cultivation chamber, avoiding temperature fluctuations and affecting the growth of edible fungi. At the same time, it can also recover heat from the discharged exhaust gas, saving energy.
4. Fermentation process control: In the liquid fermentation culture of edible mushrooms, heat exchangers are used to control the temperature inside the fermentation tank. During the fermentation process, microbial metabolism generates heat. If not removed in a timely manner, it can lead to excessive temperature and affect the fermentation effect. The heat exchanger removes excess heat by circulating cooling water or other cooling media, maintains the fermentation temperature within an appropriate range, and ensures the stability of the fermentation process and the quality of the products.
How to ventilate the storage of agricultural products
Cold storage ventilation: In cold storage, heat exchangers can be used for ventilation systems. Through heat exchange, fresh air is introduced while preventing external hot air from entering the cold storage and causing temperature fluctuations. This maintains a low temperature environment in the cold storage, reduces the operating time and energy consumption of refrigeration equipment, ensures the storage quality of agricultural products, and extends the storage period.
Granary ventilation: For granaries storing grain, the heat exchanger can adjust the temperature and humidity of the air during the ventilation process to prevent the grain from becoming moldy and deteriorated due to moisture and heat, keep the grain dry and low temperature, and ensure the safe storage of grain.
How to use heat exchangers in the livestock and poultry breeding industry
Improving air quality: Livestock farms produce large amounts of harmful gases such as ammonia and hydrogen sulfide, as well as water vapor. Heat exchangers can transfer the heat from the polluted air discharged to the fresh air entering during the ventilation process, while achieving preheating and purification of the air, reducing the indoor temperature drop caused by ventilation, providing warm and fresh air for livestock and poultry, improving the breeding environment, and reducing the incidence of livestock and poultry diseases.
Reduce stress reactions: Due to the sensitivity of livestock and poultry to changes in environmental temperature, heat exchangers can gradually bring the temperature of the introduced fresh air closer to the indoor temperature, avoiding stress reactions caused by sudden temperature changes in livestock and poultry, which is beneficial for their growth, development, and production performance.
What is the role of heat exchangers in greenhouse cultivation
1. Temperature regulation: In winter, the heat exchanger can recover the heat from the humid and hot air discharged from the greenhouse, preheat the cold air entering the greenhouse, reduce heating energy consumption, maintain stable indoor temperature, and promote crop growth. In summer, it can utilize cool nighttime air or low-temperature resources such as groundwater to cool the air entering the greenhouse through a heat exchanger, reducing indoor temperature and avoiding high temperature hazards to crops.
2. Humidity control: In some greenhouses with high humidity, heat exchange can be carried out through heat exchangers to remove moisture from the air during the cooling process, achieving the purpose of dehumidification, creating a suitable humidity environment for crops, and reducing the occurrence of pests and diseases.
The role of heat exchangers in agricultural ventilation
Energy conservation and consumption reduction: In agricultural facilities such as greenhouses and breeding farms, heat exchangers can utilize the energy of exhaust air to pretreat fresh air. For example, in winter, transferring the heat from the exhaust to the incoming cold air can increase the temperature of the fresh air and reduce heating energy consumption; In summer, the cooling capacity of exhaust can be used to cool the fresh air and reduce the cooling load of air conditioning.
Improving the environment: By using heat exchangers for heat exchange, the temperature of the air entering agricultural facilities can be brought closer to the indoor ambient temperature, reducing temperature fluctuations caused by ventilation and providing a more stable and suitable environment for crop growth or animal husbandry. At the same time, some heat exchangers can achieve complete isolation between fresh air and exhaust air, avoid cross contamination, and ensure the cleanliness of fresh air, which is particularly important for agricultural production with high environmental requirements such as aseptic cultivation and SPF level animal breeding.
