Problems solved by technology

In the prior art, in the simulated test bench proposed by Wang Junxiong et al. in the paper "Principle and Structure of Ocean Temperature Difference Energy Driving System" (Journal of North China Electric Power University, 2007, Phase 1), the hot water flow is heated by an electric heater, and the cold water flow is heated by an electric heater. With the method of forced cooling of the cooling tower, the device not only consumes a lot of electric energy, but also occupies a large space and requires a long connecting pipeline. The hot steam released by the cooling tower also causes thermal pollution to the environment

Embodiment Construction

[0014] specific implementation plan

[0015] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] As shown in Figure 1, the present invention includes: water tank 1, compressor 2, evaporator 3, temperature control expansion valve 4, condenser 5, heat sensitive element 6, return water pump 7, A flow meter 8, cold water tank 9, cooling Water pump 10, A shut-off valve 11, water supply valve 12, frequency conversion controller 13, control unit 14, B flow meter 15, hot water pump 16, B shut-off valve 17, temperature digital display 18, A thermocouple 19, B thermocouple 20.

[0017] The water tank 1 is a cuboid that is open above and filled with water. The two ends of the water tank 1 are divided into six equally along the height direction from the horizontal plane, and are separated by partitions so that the water flow forms a steady flow state. The right end of water tank 1 is a water inlet, a...

Abstract

This invention is a heat pump double water circulating system of sea thermocline simulation test bed. It belongs to the field of ocean ship engineering technology. It includes water groove, compressor, condenser, temperature controlling expansion valve, evaporator, back water pump, flowmeter, cold water tank, cold water pump, hot water pump, globe valve, water compensating valve, frequency conversion controller, control element and thermometer. This invention uses heat pump double water circulating system, which makes water conveniently transfer heat and reach the needed temperature. The cold and hot water in the water tank is controlled within 0.1m/s-0.6m/s. The temperature of cold and hot water is controlled within 8deg.C-15deg.C. It stimulates the temperature distribution and flow state of sea thermocline under the control of human being. It can greatly save the water resource and electric energy.

Description

technical field [0001] The invention relates to a double water circulation system, in particular to a heat pump double water circulation system using a heat pump ocean thermocline simulation test bench, which belongs to the technical field of ocean ship engineering. technical background [0002] The ocean thermocline is a layer of cold and hot water that naturally exists in the ocean and has a temperature step with the difference in water depth. The existence of ocean thermocline provides a particularly convenient condition for people to utilize ocean thermal energy. Therefore, for the needs of research and experiments, it is necessary to establish a test bed in the laboratory to simulate the temperature distribution and flow of the ocean thermocline. There is a flowing water layer in the test bed, and the temperature difference is between 8-15 °C. In the prior art, in the simulated test bench proposed by Wang Junxiong et al. in the paper "Principle and Structure of Ocean T...
