Key Points for the Use of Marine Fans

Marine fans are a new type of ventilation equipment manufactured from corrosion-resistant fibreglass reinforced plastic (FRP), classified as axial flow fans. Utilising a corrosion-resistant FRP outer casing, their operating principle employs negative pressure ventilation to achieve air circulation, ventilation, and cooling. 1. Starting the fan at full voltage or reduced voltage Marine fans can be started at either full voltage or reduced voltage. However, certain precautions apply. Specifically: - When starting at full voltage, the starting current should be 5-7 times the rated current. - When starting at reduced voltage, the starting torque is proportional to the square of the voltage. 2. Requirements for trial operation runs Are there requirements for the number of trial operation runs?

Marine Air Conditioning Condensate Drain Pan

The marine air conditioning condensate collection tray comprises a main collection tray body, a collection tray surround, and a filter mesh fixing module. The condensate collection tray features a structurally sound design with high practicality. During operation, the perimeter of the tray body incorporates a channel structure, with the bottom edges lower than the centre to ensure condensate first flows into the channels. The filter screen serves a dual purpose: it filters debris to prevent blockage of the outlet; Additionally, it mitigates the kinetic energy of condensate overflow during vessel motion. Both the longitudinal and transverse trapezoidal grooves feature a narrower base and wider top, thereby reducing water accumulation while facilitating easy cleaning of debris within the tray.

Principles of Marine Air Conditioning Systems

Marine air conditioning units must not only withstand harsh maritime conditions such as salt spray, mould and humidity, but also serve as vital equipment ensuring the normal operation of personnel and machinery. Their performance directly impacts crew working conditions, making reliability and maintainability paramount. The refrigeration unit employs a welded structure for structural integrity, with insulation comprising glass wool and galvanised perforated sound-absorbing panels. Key refrigeration components are designed for stability and reliability. The unit's return air valve utilises a turbine-type regulating valve with graduated display for convenient and flexible adjustment. Structural Design: The compressor and condenser are stacked vertically, arranged in a front-to-back configuration, with the compressor positioned at the rear.
