Marine absorption refrigeration air conditioning system and working method thereof

Abstract

The invention discloses a marine absorption refrigeration air conditioning system and a working method thereof. The system comprises an absorption refrigeration unit, a waste heat recycling loop and a seawater loop. The method comprises the steps that when cold supplying is conducted in summer, ship main and auxiliary engine cylinder sleeve cooling water is taken as a heat source for a generation cavity of the absorption refrigeration unit, and seawater is taken as a cold source for an absorption cavity and a condensation cavity in the loop; when heat supplying is conducted in winter, heat supplying is achieved by directly taking the cylinder sleeve cooling water as a heat source. According to the marine absorption refrigeration system, a traditional marine compression type refrigeration system is replaced, therefore, consumption of a marine air conditioning system on marine power is effectively reduced, marine waste heat and exhaust heat are fully utilized, the heat efficiency is increased by about 20%, and the overall marine energy source utilization efficiency is greatly improved.

Description

technical field [0001] The invention relates to a marine absorption refrigeration air-conditioning system and a working method thereof, in particular to a heat-recovery, high-efficiency, energy-saving, green and environment-friendly air-conditioning system that fully utilizes the waste heat of the cylinder jacket cooling water of the main and auxiliary engines of the ship, and belongs to the technical field of air-conditioning engineering. Background technique [0002] With the recovery of the world economy and trade, the shipping market has rapidly prospered. However, the contradiction between the increase of shipping costs and the relatively unchanged shipping volume has gradually become prominent. In the calculation of ship operating costs, fuel costs account for the vast majority of ship transportation costs, and energy conservation directly affects ship operating costs. At present, exhaust gas boilers, water generators and fishing boat ice making are mainly used on shi...

Problems solved by technology

However, the system uses the heat generated in the condenser and absorber as the generator heat source. The heat itself is generated during the operation of the refrigerator, and the system cannot operate spontaneously. According to the second law of thermodynamics, this heat is not enough As the heat source of the generator continuously drives the refrigerator, the technical solution uses a vacuum pump to provide the driving power of the refrigerator, but the vacuum pump has the disadvantages of large power consumption and high noise, which is contrary to the purpose of energy saving and environmental protection of the system
