Embodiment Construction

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

[0022] Such as figure 1 As shown, 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 backwater 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, B thermometer 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 conde...

Abstract

The invention provides an energy saving hot water system of a refrigerating device of a ship refrigeratory and belongs to the technical field of refrigeration and ship engineering. The invention comprises a condenser, an expansion water tank, a hot water disconnecting valve, a one-way valve, a thermograph, a flow rate meter, a programmable controller, a water charging valve, a circulation water pump, a water returning disconnecting valve, a seawater cooling loop, a three-way valve, a floater valve and a hot water tank. According to the change of water temperature and the water level of the hotwater tank, the whole energy saving hot water system can operate naturally with the regulation of the programmable controller; the seawater cooling loop is adopted to guarantee that the refrigeratingsystem of the ship refrigeratory is in a favored working state; waste heat discharged by the refrigerating device can be taken use of in maximum so that hot water for life has no requirement for additional energy consumption completely and energy consumption and the discharging level of the whole ship are reduced; the invention is a waste heat utilizing system with long-term stable operation andreliable performance and has significant economic benefit and social benefit.

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...
