Problems solved by technology

Centralized cooling / heating and air supply schemes cannot meet the needs of the rooms, and uniformly cool or heat all air-conditioning installation areas. Wind noise is extremely high; the central air-conditioning system uses refrigerant water to uniformly supply water to the water-cooling units in the room. The design of the fresh air pipeline in the system is complicated. It is easy to generate running water noise, which affects the living comfort of the crew

Abstract

The invention belongs to the technical field of ships and particularly relates to a regional dynamic circulation refrigerating and heating system. To lower the ship air conditioning system design, construction and operating cost as well as improving the ship room living comfortableness, the following scheme is provided that the system comprises an air pipe which is in a ring shape in a region defined by a plurality of living rooms; the air pipe communicates with at least one induced draft pipe, and a pretreatment heat exchanger and a fresh air supply fan are arranged in each induced draft pipe, wherein the pretreatment heat exchanger is located at the air outlet end of the fresh air supply fan; and the directions of the induced draft pipes are consistent with the circulating air directionin the air pipe. According to the regional dynamic circulation refrigerating and heating system provided by the invention, the whole regional air conditioning air supply system can provide dynamic airconditioning requirements for room requirements by means of a simple structure and effective functions, the ship air conditioning system design, construction and operating cost is lowered, and meanwhile, the ship air conditioning system safety and maintenance efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to an area dynamic cycle refrigeration and heating system. Background technique [0002] At present, the ship's central air-conditioning system adopts a centralized cooling / heating and air supply structure, or uses refrigerant water to supply water, cooling / heating to the water-cooled unit in the room. Centralized cooling / heating and air supply schemes cannot meet the needs of the rooms, and uniformly cool or heat all air-conditioning installation areas. Wind noise is extremely high; the central air-conditioning system uses refrigerant water to uniformly supply water to the water-cooling units in the room. The design of the fresh air pipeline in the system is complicated. It is easy to generate running water noise, which affects the living comfort of the crew. Contents of the invention [0003] The present invention proposes a regional dynamic cycle refrigeration and heating syste...
