High-pressure and low-humidity air-conditioning device for marine cooling aircraft

Abstract

The invention relates to a high-pressure low-humidity air conditioner device for cooling an aircraft for a boat. The high-pressure low-humidity air conditioner device comprises a box body, wherein one side of the box body is provided with an air inlet, the other end of the box body is provided with an air supply box, a first-stage air conditioning system, an air pressure boosting system and a second-stage air conditioning system are sequentially arranged in the box body in the air supply direction, the air pressure boosting system realizes the air inlet from the first-stage air conditioning system side, in addition, the air is supplied to the second-stage air conditioning system, a bypass air conditioning pipeline is arranged in the box body, one end of the bypass air conditioning pipeline is connected with an air outlet of the air pressure boosting system, the other end of the bypass air conditioning pipeline is connected with an air outlet of the second-stage air conditioning system, and an electric butterfly valve is arranged on the bypass air conditioning pipeline. Coolant water supplied by the boat and a platform is adopted, a fluorine direct evaporation system and the electric heating temperature rise are omitted, the system design complexity is greatly simplified, the potential risk is avoided, and the high-pressure low-humidity air conditioner device has the advantages of high air outlet pressure, precise temperature, low humidity and low energy consumption.

Description

technical field [0001] The invention relates to the field of marine special air-conditioning devices, in particular to a high-pressure and low-humidity air-conditioning device for marine cooling aircraft suitable for refrigeration and heating when ships, oil platforms, and land airports take off and land. Background technique [0002] At present, aviation air-conditioning units are used on ships to provide cold sources for aircraft. Fresh air is taken from the environment, and after being processed by aviation air-conditioning units, it is sent to the parts of the aircraft that need to be dehumidified or temperature-regulated. At present, the domestic support is generally suitable for aircraft air-conditioning vehicles used in civil aviation airports. The disadvantages of this aircraft air-conditioning vehicle are: 1. It cannot adapt to the marine climate, super high wind pressure, low humidity, high precision, energy saving and low consumption. demand, and the supporting pr...

AI Technical Summary

Problems solved by technology

At present, the domestic support is generally suitable for aircraft air-conditioning vehicles used in civil aviation airports. The disadvantages of this aircraft air-conditioning vehicle are: 1. It cannot adapt to the marine climate, super high wind pressure, low humidity, high precision, energy saving and low consumption. demand, and the supporting products are generally imported, which are expensive, difficult to maintain, and have a long delivery cycle; 2. Aircraft air conditioners usually use compressor refrigerants for cooling, which consume a lot of power and have a high probability of failure; 3 .Temperature adjustment at the air outlet usually adopts electric heating. Since the electric heating resistance wire takes a long time to heat up and cool down, it wastes electric energy and the control accuracy is very low.
