Compact variable air volume air conditioner for ship

Abstract

The invention relates to a compact variable air volume air conditioner for a ship. The comprises a return air adjusting air valve, a return air temperature and humidity sensor, a return air inlet silencing grating, a filter, a steam heater, a cooler, a steam humidifier, a water retaining device, a variable-frequency air supply fan, an air supply temperature and humidity sensor, a steam pipe system, a refrigerant water pipe system, an electric control box, a fresh air temperature and humidity sensor, a fresh air electric adjusting air valve and a silencing plenum cavity. The variable-frequency air supply fan adopts a high-rotating-speed variable-frequency air supply fan, fresh air passes through the fresh air adjusting air valve and return air of the return air adjusting air valve to be mixed, then passes through the filter, the steam heater, the cooler, the water retaining device and the steam humidifier in sequence, passes through the silencing plenum cavity through the high-rotating-speed variable-frequency air supply fan and then is fed into an air pipe of the air conditioning system. The main improvement lies in that the high-rotating-speed variable-frequency air feeder is adopted, the head-on wind speed of the air conditioner is increased to 4 m / s, the size of the air conditioner is greatly reduced, the weight of the air conditioner is reduced, and the mounting requirement on a special ship is met.

Description

technical field [0001] The invention relates to a ship air-conditioning and ventilating device, in particular to a ship's air-conditioning and ventilating device. Background technique [0002] The air conditioner is the core equipment to realize the control of room temperature and humidity in the ship's cabin, which is related to the living and working conditions of the ship's occupants, and is an indispensable cabin auxiliary machine in the ship's equipment. [0003] As one of the special air conditioners, marine air conditioners have lagged far behind building HVAC in the past 20 years. However, for the air conditioning and ventilation systems that account for 20% of the total ship's power consumption (cruise ships will reach 45%), energy saving is very important. status 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 th...
