Semiconductor thermoelectric air-conditioning and water-heating device

Abstract

The working principle of a semiconductor thermoelectric air-conditioning and water-heating device is that when one portion of electric energy is input, 1.5 portions of cold energy is generated on a refrigerating end face of a semiconductor thermoelectric element, and indoor return air, which is driven by a draft fan to flow downwardly and passes through vertical air side fins, is cooled by the cold energy through the vertical air side fins, so that an air-conditioning function is achieved; according to the energy conservation law, 2.5 portions of heat is generated on a heating end face of the semiconductor thermoelectric element, and water, which is driven by the siphon effect to flow upwardly and passes through the side wall of a hot water tank and vertical hot water side fins, is heated by the heat energy through the side wall of the hot water tank and the vertical hot water side fins, and the heated water is insulated by a thermal insulation material at the outer side of the hot water tank; while the device is in use, cold water enters the hot water tank from a water inlet, and after the cold water is heated, hot water flows out of the hot water tank from a water outlet, so that a water-heating function is achieved. The energy efficiency ratio of air conditioning to water heating reaches up to 4.

Description

(1) Technical field [0001] The invention relates to the technical field of realizing dual functions of air conditioning and hot water by using the cooling and heating principles of semiconductor thermoelectric elements. (2) Background technology [0002] Semiconductor thermoelectric refrigeration refrigerator: It is equipped with multiple sets of semiconductor thermoelectric elements, and its cooling capacity is released into the refrigerator through a heat exchanger, and its exterior is insulated by thermal insulation materials to ensure the refrigeration temperature; ambient air. Because no refrigerant and compressor are needed, and the manufacturing process is relatively low, it meets the requirements of energy saving and environmental protection. [0003] Electric water heater: The electric energy is directly converted into heat energy through the electric heating rod, and released to the hot water in the hot water tank, and its exterior is insulated by thermal insulati...

AI Technical Summary

Problems solved by technology

[0005] 1. During the cooling process of semiconductor thermoelectric elements, the energy efficiency of converting input electric energy into cooling capacity is relatively low, usually only about 1; and the heating capacity is released to the environment and wastes heat energy

Therefore, the products formed are difficult to be fully promoted

[0006] 2. Electric water heaters consider electric heat conversion efficiency and heat preservation loss, and only 50%-98% of each input electric energy is finally converted into actual heat energy, so its energy efficiency is relatively low, which does not meet the requirements of modern society for energy saving and environmental protection
