A marine fresh air efficient variable air volume energy recovery air conditioning system

Abstract

This utility model relates to a marine 100% fresh air high-efficiency variable air volume energy recovery air conditioning system, including a fresh air inlet box, an air supply filter, a heat recovery rotor, a surface cooler, a water baffle, a humidifier, an air supply fan, a fresh air supply static pressure box, a return air inlet box, a return air filter, a return air fan, and an electrical control box. Hot water heaters are installed between the air supply filter and the heat recovery rotor, and between the heat recovery rotor and the surface cooler. A temperature controller is installed on the outlet side of the hot water heater between the air supply filter and the heat recovery rotor. A temperature and humidity sensor and a micro-pressure differential sensor are installed inside the fresh air supply static pressure box. The heat recovery rotor is a molecular sieve total heat recovery rotor, consisting of a rotor with a molecular sieve adsorption layer structure having adsorption micropores no larger than 4 angstroms coated on the surface of the core substrate, and thickened to achieve a heat recovery efficiency of over 75%. This system has high heat recovery efficiency, low energy consumption for fresh air treatment, and intelligent variable air volume adjustment, making it suitable for use in marine air conditioning systems.
