Abstract

The invention relates to an LNG cold energy utilization device including an LNG liquid storage tank, an LNG heat exchanger, an intermediate heat exchanger, a Y-type filter, a closed expansion water tank, a pressure gauge, a fan, a surface air cooler and a heat regenerator; an outflow pipe of the LNG liquid storage tank communicates with an inflow pipe of the LNG heat exchanger through a circulating medium circulation pump, an outflow pipe of the LNG heat exchanger communicates with an inflow pipe of the intermediate heat exchanger through a circulating medium circulation pump, a glycol fillingport communicates with a water supply valve through a pipeline, the water supply valve communicates with the Y-type filter through a pipeline, an outflow pipe of the intermediate heat exchanger communicates with the Y-type filter, the Y-type filter communicates with the pressure gauge through the water supply valve, the closed expansion water tank communicates with the pressure gauge through thewater supply valve, and the pressure gauge communicates with the surface air cooler through a one-way stop valve, and the surface air cooler communicates with the heat regenerator through a pipeline.The LNG cold energy utilization device has the advantages that LNG cold energy on a ship is applied to ship air conditioning systems, and energy saving and environmental protection are achieved.

Description

technical field [0001] The invention relates to an LNG cold energy utilization device and belongs to the technical field of ship equipment. Background technique [0002] Ship air-conditioning system is widely installed on ships as equipment to improve the living comfort of the crew. However, the ship air-conditioning system consumes a large amount of ship power, which indirectly leads to environmental pollution. In recent years, liquefied natural gas (LNG) powered ships have been favored by the ship market for their cleanliness and environmental protection. LNG is rich in a large amount of cold energy, and it has strong practical significance to apply the cold energy of LNG on ships to the ship air conditioning system. However, there is currently no utilization device for applying LNG cold energy to ship air conditioning. Contents of the invention [0003] The purpose of the invention is to provide an LNG cold energy utilization device. [0004] The problem to be solved...
