Abstract: The domestic small inland ship has become a new business growth point for the shipbuilding industry under the background of the continuous shrinking of the large and the medium ship market. A design idea different from those of the large and medium sea-going vessels has been proposed for the air-conditioning system of the small inland ships.The modular unit of the water source heat pump is applied with the VRV multi-split air conditioning system and the total heat exchange fresh air system.While ensuring the indoor temperature and humidity and the demand of fresh air for personnel, the system control level and the human comfort are improved together with the advantages of energy saving, weight reduction, space saving, safety redundancy and convenient expansion.

Key words: small inland ship, varied refrigerant volume (VRV), water source heat pump, total heat exchange, air conditioning system, fresh air system
