Commercial Ventilation and Energy Recovery

　　Adequate indoor air quality(IAQ)involves many factors depending on the local situation and climate.Health issues like breathing problems can arise from air containing dust,pollen,or other contaminants.A poor indoor environment can also damage buildings.

　　Commercial(non-residential)air handling units tend to be larger units designed for buildings like offices,hotels,and airports.The challenge is to achieve a comfortable IAQ with as little energy input as possible.This means that pressure drop should be low(less fan power is needed)and thermal/humidity efficiency high(less energy consumed for heating/cooling/humidity control).

　　Depending on the geographical region,the primary purpose of the heat exchanger shifts between heating or cooling(and maybe also dehumidifying)the outdoor air before it enters the building.

　　The air handling unit(AHU)is at the center of a ventilation system.At a minimum,an AHU includes one or several fans in each air channel to move the air through the unit.Filters on either side remove dust,pollen,etc.,and protect the fans.Finally,a heat exchanger transfers the required heat or humidity from the exhaust air to the supply air.

　　Implementing an air-to-air heat exchanger is an excellent way to utilize what is usually considered waste heat.An air-to-air heat exchanger will use the temperature difference between the supply and exhaust air to increase the system’s efficiency.There are two types of air-to-air heat exchangers:rotary and plate heat exchangers.

　　The type and exact configuration depends on the application.Both types are made of aluminum,which has excellent properties such as efficient heat transfer capabilities and an extraordinarily long life span.We offers numerous design variables and options for each product,enabling perfect fit and performance in every AHU.

Indirect Cooling in Data Centers

Modern data centers are remarkably technologically complex, and keeping them running safely and efficiently requires continual close monitoring and management.

Maintaining the correct temperature is among the most important tasks faced by data center managers. Should the temperature and humidity rise to excessive levels inside the data center, condensation can start forming, damaging the machines within. This can cause massive damage and disruption, so it must be avoided at all costs. Fortunately, various technologies are on hand that can help keep data center temperatures at the right level.

There are numerous ways to cool a data center. Indirect air cooling uses external air, but by including an air-to-air heat exchanger, the outside air is kept in a separate loop, providing cooling without entering the server room.

Indirect cooling methods benefit by not contaminating the inside air with outdoor air pollutants and humidity. A heat exchanger keeps both airstreams separated while transferring the heat from the inside to the outside of the data center building. Consequently, the ambient and indoor air never mix.

Dry cooling is usually sufficient if the data center is located in a consistently low-temperature area, meaning no water is involved. However, by spraying water on the ambient air side of the heat exchanger, an evaporative effect is achieved, resulting in a lower indoor air temperature. This method is called indirect evaporative cooling (IEC).

Ideally suited for warm, dry climates, IEC provides excellent cooling potential with low operational- and first-cost. Ambient temperature reductions of 6-8 °C (10-15 °F) are typical in summer conditions. IEC provides up to 28% in energy savings compared to conventional free cooling and 52% to air-cooled Free Cooling alternatives.

Evaporative cooling requires a plate heat exchanger that balances high efficiency with low pressure drop, offers solid corrosion protection, and reliable water tightness. Cross-flow heat exchangers meet all these requirements while providing outstanding cooling capacity.

Our crossflow heat exchangers, especially with evaporative cooling technology, provide an efficient, low-cost, and environmentally friendly alternative to traditional cooling methods.

A rapid method for eliminating white smoke

The principle of using a condenser for dehumidification to eliminate white smoke is mainly based on the physical changes of water vapor in the flue gas. The condenser cools the flue gas with low-temperature water or air, gradually reducing its temperature, and the water vapor inside begins to condense into small water droplets. These small water droplets gather inside the condenser and eventually form liquid water, which is then removed through drainage pipes. Dehumidification through a condenser is an effective technical means to eliminate white smoke. It can not only reduce visual pollution, but also help improve the operational efficiency and energy-saving effect of environmental protection equipment. We can provide you with a suitable dehumidification solution for flue gas, which is both economical and environmentally friendly. Welcome to consult us via email.

Efficient equipment for removing industrial flue gas

Industrial flue gas desulfurization equipment with heat exchange technology to reduce the water vapor content in flue gas, thereby eliminating the white smoke plume generated during chimney emissions. The following are several common methods for flue gas whitening:

Flue gas heating technology: The desulfurized wet flue gas is heat exchanged with industrial high-temperature flue gas through a heat exchanger to increase the emission temperature of the flue gas, thereby reducing the relative humidity of the flue gas and avoiding the condensation of water vapor to form white smoke. This method can effectively reduce the generation of white smoke, but it requires a certain amount of energy to heat the smoke.

Flue gas condensation technology: First, partially condense the water vapor in the saturated flue gas, and then heat the flue gas. This method reduces the formation of white smoke by lowering the moisture content in the flue gas, while also recovering some water resources.

MGGH technology: Install flue gas cooling heat exchangers before and after electrostatic precipitator, install flue gas heating heat exchangers after desulfurization, and set up a heat medium water circulation system. This technology extracts the heat from the original smoke to heat the clean smoke, which usually needs to be raised to 75-80 ℃ to avoid the production of white smoke.

In summary, these methods each have their own advantages and disadvantages, and are suitable for different industrial environments and needs. When selecting specific flue gas desulfurization technologies, factors such as process conditions, waste heat resources, and investment requirements need to be considered.

Smoke Scrubber :Efficient removal of white smoke with physical methods

The smoke scrubber condenses water vapor in the flue gas into liquid through a condenser, and gas pollutants adhere to the condensed liquid before being discharged through exhaust gas. This technology does not require a collector, but relies on the precipitated liquid to carry away pollutants, thereby reducing operating costs and minimizing the environmental pollution caused by white smoke.

The white smoke removal equipment produced by our company has a compact design layout, flexible installation, and easy operation, which can efficiently and quickly solve the white smoke generated in industrial production. Mainly used for desulfurization and whitening of flue gas from coal-fired boilers, gas-fired boilers, power plants, metallurgy and other industries.

The heat exchange core of the computer room's heat dissipation energy-saving device is an efficient heat dissipation solution specifically designed for data centers or server rooms. By optimizing heat exchange efficiency, energy consumption can be reduced and system performance can be improved. The heat exchanger produced by our company uses hydrophilic aluminum foil as the heat exchange material, and the surface has been specially treated to have excellent hydrophilicity, which can promote the rapid formation and removal of condensed water. During the heat exchange process, the hydrophilic layer can effectively increase the heat exchange area and improve the heat exchange efficiency. Adopting a multi-layer microchannel design increases the contact area between the fluid and the metal wall, thereby improving the heat transfer efficiency. Greatly improved the energy efficiency ratio of data centers and reduced operating costs.

Energy saving scheme for heat recovery of central air conditioning system

In the operation of central air conditioning systems, we can adopt high-efficiency heat exchangers for energy-saving renovation plans, and can choose plate heat exchangers or microchannel heat exchangers with high heat transfer efficiency and low fluid resistance. Our heat exchanger has a larger heat transfer area and more efficient heat transfer performance, which can reduce energy consumption under the same heat transfer conditions. Install a waste heat recovery device in the central air conditioning system to recover and reuse the emitted heat. It can also be combined with heat pump technology, which is an efficient way of transferring heat energy by consuming a small amount of electricity or fuel energy to transfer the heat from a low-temperature heat source to a high-temperature heat source. The application of heat pump technology in central air conditioning systems can improve the coefficient of performance (COP) of the system and reduce energy consumption.
