Embodiment Construction

[0021] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] As shown in Figure 1, the present invention includes: condenser 1, A thermometer 2, expansion tank 3, electric hot water stop valve 4, one-way valve 5, flow meter 6, programmable controller 7, electric water supply valve 8, C Thermometer 9, circulating water pump 10, electric return water stop valve 11, sea water cooler 12, sea water pump 13, sea valve 14, electric bypass valve 15, electric three-way valve 16, float valve 17, hot water tank 18, thermometer B 19.

[0023] The condenser of the refrigeration unit of the cold storage of the ship sailing at sea is a seawater condenser, which is generally cooled by seawater, and the material of the condenser needs to be resistant to seawater corrosion. The condenser 1 in the present invention does not need to consider the corrosivity of seawater, and only a common shell-and-tube condens...

Abstract

The invention relates to an energy-saving hot water system for a refrigeration device in a ship's cold storage, belonging to the technical field of refrigeration and ship engineering. The invention includes a condenser, an expansion tank, a hot water stop valve, a one-way valve, a thermometer, a flow meter, a programmable controller, a replenishment valve, a circulating water pump, a return water stop valve, a seawater cooling circuit, a three-way valve, a float valve, hot water tank. According to the change of water temperature and water level in the hot water tank, through the adjustment of the programmable controller, the entire energy-saving hot water system can operate normally, and the seawater cooling circuit can ensure that the refrigeration system of the ship's cold storage is in a favorable working state and can be used to the maximum extent. The waste heat discharged from the refrigeration device makes domestic hot water use no additional energy consumption at all, which reduces the energy consumption and emission level of the whole ship. It is a waste heat utilization system that can operate stably for a long time and has reliable performance, and has significant economic benefits. and social benefits.

Description

technical field [0001] The invention relates to an energy-saving hot water system, in particular to an energy-saving hot water system for a refrigeration device in a ship's cold storage, and belongs to the technical field of refrigeration and ship engineering. Background technique [0002] The condenser in the cold storage refrigeration system will release the heat rejected by the entire cold storage. Whether it is an inland river, offshore or ocean-going ship, the temperature of the heat carried by the cooling water of the condenser is between 40-50 ℃, which has the value of reuse, but it is all discarded and wasted at present. The heat discarded by the cooling water of the condenser increases greatly with the increase of the tonnage of the ship and the cooling capacity of the cold storage, and it is a considerable amount of heat energy that can be used. In the prior art, the utility model patent with application number 95212554.4 and titled "Water Heater Utilizing Waste H...
