In recent years, "shipping carbon reduction" in the shipbuilding industry has increasingly become the focus of attention in the shipbuilding industry and the shipping industry. According to statistics, the current carbon dioxide emitted by ships has reached 1.12 billion tons, accounting for about 3% of the total global greenhouse gas emissions. However, the electricity consumed by the operation of traditional air-conditioning equipment on ships accounts for about 20%, which is quite high energy. Energy consumption, how to save energy and reduce emissions in the ship sector has become a key focus of the industry.

There are 4 ways to save energy and reduce emissions on ships:

1. Ship energy consumption quota management (different fuel consumption standards are formulated according to different models and working principles).

2. Reasonably shorten the voyage

3. Use of economic speed

4.Reduce unnecessary round trips between the working ship dock and the working dock.

The ship’s rotor dehumidification air conditioner uses a combination of a dehumidification rotor and a vapor compression refrigeration system. It uses the energy generated by the ship’s waste heat as the driving energy, and uses the lower temperature seawater as the inter-stage cooling water source. Sensible heat load and replacement heat load are treated separately to achieve the effects of temperature regulation and humidity control.

And puresci has new research technologies on ships and has achieved great results in the shipbuilding industry, saving a lot of energy consumption for the shipbuilding industry.

The construction of the ship's rotor dehumidification and air conditioning system adopts a single rotor two-stage dehumidification cycle. The system process includes two processes of processing air and regenerating air. The treated air is dried twice on the dehumidification rotor. After each drying, seawater is used for intermediate cooling, and finally the auxiliary compression refrigeration unit is assisted to cool to the air supply state.

Fresh air and return air are mixed in a certain proportion to form processing air, and the mixing position is before entering the rotor for the first dehumidification. The regeneration air adopts cabin return air and is heated by the saturated steam produced by the waste heat boiler. The heated regeneration air is sent to two regeneration zones respectively, and then discharged to the outdoors after regeneration.

The use of such a rotor dehumidifying air conditioning system not only reduces the energy consumption of the ship's air conditioning, but also reduces the pollution of the waste heat to the marine environment and the emission of carbon dioxide from the ship.

puresci's high-efficiency and high-temperature dehumidification rotor PSS-S is the first product that Puresci has harvested in the process of focusing on dehumidification rotor products and solutions, which is different from the previous ordinary silica gel rotor products. At present, this dehumidification rotor . It has been used in many domestic shipyards. It has been micro-optimized on the material of the dehumidification rotor, and on the basis of 82% sizing rate, hydrophilic hydroxyl groups are added to improve the adsorption performance of the rotor. To a certain extent, the dehumidification capacity of the dehumidification wheel is increased, the dehumidification operation speed is accelerated, and the dehumidification depth is deepened. It provides a more efficient high-temperature desiccant rotor for the ship's rotor dehumidification system, saving more energy.
