Marine air conditioner system based on lithium bromide-water and refrigerating method

Abstract

The invention discloses a marine air conditioner system based on lithium bromide-water and a refrigerating method. Waste heat of a marine main engine is converted into high-temperature steam, heat isexchanged in a lithium bromide-water heat exchanging circulating system, vapor (refrigerant steam) is obtained, after entering a condenser, the cryogen steam is cooled through cooling water in the condenser, latent heat of vaporization is discharged, after the temperature is reduced, the cryogen steam is coagulated into high-pressure and low-temperature liquid cryogen water, the cryogen water is subjected to throttling depressurization through a U-shaped pipe and then enters a water disk of an evaporator, then the cryogen water is evenly sprayed to the outer surfaces of pipe clusters of the evaporator through a spraying device of the evaporator, the cryogen water is vaporized and absorbs a great amount of heat of refrigerant water in the evaporator, the temperature is reduced, the effectsof cooling and refrigerating are achieved, and the refrigerating task of the marine air conditioner system is completed. The marine air conditioner system can comprehensively utilize the marine wasteheat and is low in energy consumption, economical, environmental friendly, safe, good in noiseless effect, easy to manufacture and convenient to operate, maintain and repair, and the number of vibration components of the whole device is small.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration, and relates to a marine air-conditioning and refrigeration technology, in particular to a lithium bromide-water-based marine air-conditioning system and a refrigeration method. Background technique [0002] Lithium bromide absorption refrigeration is a technology that uses exhaust gas boilers to collect the waste heat of the main engine of the ship and convert it into heat energy for heat transfer to achieve the cooling effect. Lithium bromide and water are used as the heat transfer medium, and the heat is refrigerated by the evaporator. [0003] Existing air-conditioning and refrigeration systems generally consist of compressors, condensers, refrigeration heat exchangers, expanders or throttling mechanisms, and some auxiliary equipment. The compression refrigeration system uses freon as the refrigerant, which has the advantages of easy operation and low price. The ut...

AI Technical Summary

Problems solved by technology

The compression refrigeration system uses freon as the refrigerant, which has the advantages of easy operation and low price. The utilization rate of the traditional compression refrigeration system as the refrigeration medium is low; 3) The traditional compression refrigeration system has problems such as high energy consumption and high noise, which is not conducive to environmental protection; 4) Freon will decompose toxic gas when it comes into contact with an open flame , harmful to human body
