Compact and low-noise ship variable air volume air conditioner

Abstract

The invention relates to a compact and low-noise ship variable air volume air conditioner. A fresh air port, an air return port and an air supply outlet are formed in a mixed box; a channel from the fresh air port to the air supply outlet is provided with a fresh air electric regulating air valve, a fresh air temperature and humidity sensor, a fresh air pre-heater, a fresh air induced draught fan, a filter, a steam heater, a cooler, a steam humidifier, a water retaining device, a variable frequency air supply centrifugal fan and an air supply temperature and humidity sensor sequentially; and a channel of the air return port is provided with an air return regulating air valve, an air return temperature and humidity sensor and air return port silencing grille. The fresh air electric regulating air valve and the fresh air induced draught fan conduct combined control over the fresh air volume, and when the total air volume is changed, fresh air supply with quantified air volume is guaranteed; and fresh air and return air are mixed in the mixed box, sequentially pass through the filter, the steam heater, the cooler, the steam humidifier, the water retaining device and the variable frequency air supply centrifugal fan sequentially and are sent into an air pipe of an air conditioner system through the variable frequency air supply centrifugal fan, so that centralized treatment of refrigeration, heating and dehumidification of air supply in the air conditioner area is achieved.

Description

technical field [0001] The invention relates to a marine air-conditioning and ventilating device, in particular to a variable-air-volume air-conditioner suitable for ships. Background technique [0002] As a kind of special air conditioner, the development of marine air conditioner in the past 20 years has lagged far behind that of building HVAC. For the air-conditioning and ventilation system that accounts for 20% of the total ship's power consumption (cruise ships will reach 45%), energy saving has a very important position and practical significance (see literature: application of ship variable air volume air-conditioning system [J] Shanghai Shipbuilding 2011.1.62-64 ), so the variable air volume air-conditioning technology, which takes into account both energy saving and comfort, has gained wide application prospects in ships. Although my country is a big shipbuilding country, there is still more room for improvement in ship equipment. [0003] At present, there is no pu...
