The difference between air conditioning box MAU and AHU

In modern chemical production, air conditioning system is an important equipment to ensure production safety, energy saving and environmental protection. Among them, the main air conditioning unit (MAU) and the main energy supply station (AHU) in the air conditioning box are the core components of the air conditioning system. Although both MAU and AHU play key roles in air conditioning systems, there are significant differences in structure, function and application. This article provides an in-depth analysis of the differences between MAU and AHU to help chemical industry professionals better understand, design and maintain air conditioning systems.

Air conditioning box MAU and AHU basic concept

In chemical production, the main purpose of the air conditioning system is to cool down, remove moisture, dust and deodorize the production area. In order to achieve this goal, the air conditioning system usually consists of multiple devices, including the main air conditioning unit (MAU) and the main energy supply station (AHU) of the air conditioning box.

MAU: Main air conditioning unit in the air conditioning box

MAU is the core equipment in the air conditioning box responsible for temperature and humidity control in the production area. It usually includes condenser, evaporator, compressor, liquid ring cooler and other core components. The role of the MAU is to cool the air in the production area to a suitable temperature and to improve the air quality through dehumidification, dust removal and other operations.

AHU: Energy Supply Terminal

AHU is the main control station of the air conditioning system and is responsible for providing the required heat and power to the entire air conditioning system. The AHU is usually located at the top of the air conditioning system, connected to the MAU through a heat exchanger, and exchanges heat with the air in the production area through a steam system. The main function of AHU is to manage and regulate the energy consumption and equipment operating status of the entire air conditioning system.

MAU and AHU main differences

In order to better understand the difference between MAMAU and AHU, the following is a detailed analysis from the aspects of energy supply mode, control mode and application scope.

1. Energy supply mode

MAU and AHU are significantly different in energy supply mode. MAU mainly exchanges heat with the air in the production area through a heat exchanger, while AHU provides steam and power to MAU through a steam system. The main energy supply mode of AHU is through the steam cycle system, which transfers steam to the MAU for heating or cooling.

2. Control mode

The control methods of MAU and AHU are also significantly different. The MAU usually controls the temperature and humidity of the production area through a temperature controller and a humidity controller. AHU controls the steam system through steam temperature controller and pressure controller, so as to adjust the running state of the whole air conditioning system.

3. Application scope

The scope of application of MAU and AHU is also different. MAU is mainly used in the production area of the air conditioning box, responsible for the air cooling, dehumidification and dust removal operations. AHU is responsible for the energy supply and energy management of the entire air conditioning system, including heat recovery, heat distribution and equipment operation status monitoring.

MAU and AHU in Chemical Production

In chemical production, the cooperative work of MAU and AHU is an important guarantee to realize production safety, energy saving and environmental protection. The following is an analysis of the specific applications of MAU and AHU in chemical production in terms of production environment, energy consumption and equipment management.

1. Production environment

In chemical production, the temperature and humidity of the production area have an important impact on the production process and equipment operation. Through cooling and dehumidification operations, MAU can reduce the temperature of the production area to a safe range, effectively remove moisture and impurities in the air, and ensure the normal operation of the equipment and the safety of the production process.

2. Energy consumption

In chemical production, energy consumption is a key link to be controlled. Through the steam cycle system, AHU can achieve efficient use of energy and reduce energy waste. Through temperature and humidity control, MAU can also optimize energy use and improve the overall energy efficiency of the system.

,3. Equipment management

In chemical production, equipment management is an important link to ensure the smooth progress of production. Through the cooperative work of MAU and AHU, the comprehensive management of the air conditioning system can be realized, including the operation status monitoring, fault prevention and maintenance of the equipment. The efficient operation of MAU and AHU can effectively extend the service life of equipment and reduce maintenance costs.

Summary

MAU and AHU are the key components of air conditioning system in chemical production, although they have obvious differences in energy supply mode, control mode and application range, but in chemical production, their collaborative work is an important guarantee to achieve production safety, energy saving and environmental protection. With an in-depth understanding of the differences and applications between MAU and AHU, chemical industry professionals can better design and manage air conditioning systems to increase productivity, reduce energy consumption, and ensure the safety of equipment and employees.
