Working principle of plate air-to-air heat exchanger

Plate air-to-air heat exchanger is a commonly used heat exchange equipment, and its working principle is as follows:

The plate air-to-air heat exchanger is composed of a series of parallel metal plates, and a series of channels are formed between the plates. The heat medium flows in these channels. When the heat medium flows in the plate air-to-air heat exchanger, the heat medium transfers heat to the plate, and then the plate transfers heat to the other side of the heat medium, thereby achieving heat transfer and heat exchange.

The working principle of the plate air-to-air heat exchanger can be divided into two ways: direct heat transfer and indirect heat transfer.

Direct heat transfer: Direct heat transfer refers to the heat medium flowing directly through the plate, transferring heat to the other side of the heat medium. This method is suitable for situations where the temperature difference between the two sides of the heat medium is small.

Indirect heat transfer: Indirect heat transfer refers to the heat medium transferring heat to the other side of the heat medium through the plate. This method is suitable for situations where the temperature difference between the two sides of the heat medium is large.

In the plate air-to-air heat exchanger, the flow of the heat medium has two ways: one-way flow and two-way flow. One-way flow means that the heat medium flows in only one direction, while two-way flow means that the heat medium can flow in two directions. Plate air-to-air heat exchangers with two-way flow have higher heat exchange efficiency, but they are also more complex and expensive.

In summary, the plate air-to-air heat exchanger achieves heat transfer and heat exchange between heat media through the channels between plates. Its working principle can be divided into direct heat transfer and indirect heat transfer, and the flow of the heat medium has one-way flow and two-way flow.

Air filtration box and air heat recovery box

An air filtration box and an air heat recovery box are two common air handling devices used to improve indoor air quality and enhance energy efficiency.

Air Filtration Box: An air filtration box is a device used to filter and purify indoor air. It typically includes a filtration system that effectively removes particles, dust, pollen, bacteria, viruses, and other pollutants from the air. The air filtration box is usually installed in the ventilation system, where the air passes through the filter before being distributed into the indoor space, providing clean and healthy indoor air.

Air Heat Recovery Box: An air heat recovery box is a device used to recover and utilize the heat energy from indoor air. The heat energy in the indoor air is typically expelled outdoors through exhaust. The air heat recovery box employs a heat exchanger to transfer the expelled indoor air's heat to fresh outside air. This allows for the recovery of heat energy while expelling waste air, thereby improving the efficiency of air heating and reducing energy consumption.

Air filtration boxes and air heat recovery boxes are often used in combination to achieve comprehensive air treatment. The air filtration box ensures clean and purified indoor air, while the air heat recovery box provides energy recovery and energy-saving benefits. These devices play a vital role in providing comfortable and healthy indoor environments, particularly in terms of efficient energy utilization and environmental preservation.

Several types of air waste heat recovery heat exchangers

There are several types of air waste heat recovery heat exchangers:

Plate heat exchanger: This type of heat exchanger uses a series of metal plates to transfer heat between two fluids. The plates are arranged in a way that allows the fluids to flow in opposite directions, maximizing heat transfer efficiency.

Shell and tube heat exchanger: This type of heat exchanger consists of a series of tubes inside a larger shell. One fluid flows through the tubes while the other flows around the tubes in the shell. Heat is transferred between the two fluids through the tube walls.

Heat pipe heat exchanger: This type of heat exchanger uses a sealed pipe filled with a working fluid that evaporates and condenses to transfer heat between two fluids. The working fluid absorbs heat from one fluid, evaporates, and then condenses to release the heat to the other fluid.

Run-around coil heat exchanger: This type of heat exchanger uses two separate coils, one in each fluid stream, connected by a pump and a heat exchanger. Heat is transferred between the two fluids as they flow through their respective coils and the heat exchanger.

Rotary heat exchanger: This type of heat exchanger uses a rotating wheel with a heat-absorbing material to transfer heat between two fluids. One fluid flows through the wheel while the other flows around the wheel. Heat is transferred between the two fluids as the wheel rotates.

What are the application scenarios of air waste heat recovery heat exchangers

The application scenarios of air waste heat recovery heat exchangers are quite extensive, mainly including the following aspects:

Industrial production: In the process of industrial production, many devices generate a large amount of waste heat, such as dryers, heat treatment furnaces, melting furnaces, etc. This waste heat can be recovered and utilized through air waste heat recovery heat exchangers to reduce energy consumption and improve production efficiency.
