Study on Air Supply Control of Marine Variable-Air-Volume Air-Conditioning System

Junjie Guo, Xiaoli Meng, Qiang Ma
Abstract—This study, taking Marine Variable-air-volume Air-conditioning System (VAV A/C system) as a research object, designed experimental platform of VAV A/C system and proposed control strategy of air supply volume of the system. Furthermore, this study carried out a comparative study of two different air supply control methods, namely, controlling static pressure of supply air by control unit of static pressure and by frequency conversion fan. Therefore, change in parameter such as cabin temperature, terminal opening, and operating frequency of compressors and fan, can be investigated under the conditions of cooling, setting cabin temperature and step change of cabin load. The research shows that both control methods can realize satisfactory control over temperature of air-conditioning cabin. What is more, power consumption of the two systems is investigated under the same working condition. Study shows that Marine VAV A/C system whose supply air static pressure is controlled by frequency conversion fan is more energy-saving than that controlled by static pressure control unit.

Index Terms—Marine, variable-air-volume system, supply air, control, energy-saving.
