The importance of cooling for solar inverters

Leave a comment

Solar inverters generate heat during operation due to energy losses in their internal power devices during the conversion of electrical energy, which are released in the form of thermal energy. If this heat is not dissipated in a timely manner, the temperature of the inverter will continue to rise.

Excessive temperature can have a negative impact on the performance and lifespan of inverters. On the one hand, an increase in temperature can lead to a decrease in the performance of power devices, a decrease in conversion efficiency, and thus affect the overall power generation efficiency of the solar power generation system. On the other hand, long-term high-temperature operation will accelerate the aging of components, increase the probability of faults, and shorten the service life of inverters.

How does the heat exchanger function in the mushroom cultivation workshop

Leave a comment ,

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.

Leave a comment ,

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

Leave a comment ,

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.

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

Leave a comment ,

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.

Heat recovery system for paint booth

Leave a comment , , ,

The heat recovery system of the paint booth mainly recovers the heat from the exhaust gas discharged from the paint booth through a heat exchange device, which is used to preheat the fresh air or other heating needs entering the paint booth, in order to achieve energy-saving purposes.
In the heat exchanger, the high-temperature exhaust gas discharged from the paint booth and the fresh air (or other heated medium) entering the paint booth flow on both sides of the partition wall, and heat is transferred through the partition wall. Due to the lack of direct contact between exhaust gas and fresh air, the mixing of the two is avoided, ensuring the cleanliness of the air. The heat of high-temperature exhaust gas is transferred to the partition wall, which then transfers the heat to fresh air, raising the temperature of the fresh air and achieving heat recovery and utilization.

Application of Commercial Ventilation Heat Exchanger

Leave a comment ,

Our commercial ventilation heat exchanger is a device used in the ventilation system of commercial buildings. Its main application principle is to use heat exchange technology to recover heat or cold from indoor polluted air while discharging it, in order to preheat or pre cool the fresh outdoor air introduced, thereby achieving energy conservation and improving indoor air quality. The specific principle is as follows:
Ventilation principle
Commercial ventilation heat exchangers are usually installed in the ventilation systems of commercial buildings, which use mechanical ventilation to expel polluted indoor air and introduce fresh outdoor air into the room.
This can ensure the freshness and circulation of indoor air, meet people's breathing needs in commercial environments, and also help maintain appropriate indoor temperature and humidity.
Heat exchange principle
There is a special heat exchange core inside the heat exchanger. When the air discharged from indoors and the air entering from outdoors flow in the heat exchange core, heat transfer occurs due to the temperature difference between the two.

The role of heat exchanger in sludge drying process

Leave a comment ,

Heating medium: The heat exchanger transfers heat to the drying medium (such as air, nitrogen, etc.) to increase its temperature. The hot drying medium comes into full contact with the sludge and transfers heat to the sludge through convection, conduction, and other means, causing the water in the sludge to absorb heat and evaporate into steam, thereby achieving the drying of the sludge.
Recycling waste heat: During the sludge drying process, a large amount of exhaust gas containing heat is generated. The heat exchanger can cool the exhaust gas and recover the heat from it. The recovered heat can be used to preheat fresh air or drying medium entering the dryer, as well as for other process links that require thermal energy, thereby improving the energy utilization efficiency of the entire drying system and reducing energy consumption.
Removing moisture: During the sludge drying process, the heat exchanger can not only heat the drying medium, but also condense the water vapor in the drying medium into liquid water through cooling, thereby achieving dehumidification of the drying medium. Dehumidification of the drying medium is beneficial for improving its ability to absorb moisture from sludge and enhancing the drying effect. For example, in some sludge drying systems that use circulating drying media, by setting up cooling heat exchangers to dehumidify the circulating air, the drying speed of sludge can be increased by 20% -30%.
