Low temperature air supply air conditioner device for naval vessels and control method thereof

Abstract

The invention relates to a low temperature air supply air conditioner device for naval vessels and a control method thereof. The low temperature air supply air conditioner device comprises an air conditioner, a fresh and return air mixing box which is provided with a primary return air port and a fresh air port, and a PLC control system. The primary return air port is provided with a primary return air valve and a first temperature and humidity sensor; the fresh air is provided with a fresh air valve; the air conditioner is provided wit a secondary return air port; the secondary return air port is provided with a secondary return air valve and a second temperature and humidity sensor; an exhaust box of the air conditioner is provided with a third temperature and humidity sensor; and the first return air valve, the second return air valve, the first temperature and humidity sensor, the second temperature and humidity sensor, the third temperature and humidity sensor and the fresh air valve are all connected with the PLC control system. In the invention, the shell of the air conditioner is provided with a primary air port, the secondary return air port and the fresh air port; a plurality of temperature and humidity sensors are matched with a plurality of air valves to ensure the low temperature air supplying and the temperature control accuracy, exactly control the water supply temperature and effectively control air supply condensation. The device is simple and compact in structure, high in service accuracy of low temperature air, and high in safety. The device is fit for naval vessels and submarines and the like.

Description

technical field [0001] The invention relates to a low-temperature air-supply air-conditioning device, in particular to an air-conditioner capable of effectively preventing condensation from being generated by low-temperature air-supply and a control method thereof. Background technique [0002] The United States began to pay attention to ice storage technology as early as the 1980s, and a low-temperature air supply system appeared. In the late 1990s, the Cold Air Distribution System Design Guide document 1 was compiled. Japan began to invest in practical research on ice storage technology in the 1990s, but the research on low-temperature air-supply systems appeared relatively late. In 2004, the Japanese Society of Air Conditioning and Sanitation compiled and published "Planning and Development of Low-Temperature Air-Conditioning Air-Conditioning Systems". Design" document 2, so far, the United States and Japan, the two major air-conditioning technology giants, have summarize...
