Abstract

The invention discloses a heat pump water heater with a nano phase change thermal storage material. The water heater consists of a condenser filled with nano phase-change energy storage materials, a compressor, a throttling element and an evaporator. It is characterized in that the evaporator absorbs heat from the air to evaporate the heat-transfer working medium, and the temperature and pressure of the working medium steam rise after being compressed by the compressor. When the high-temperature steam is condensed into liquid through the nano energy storage condenser, the heat released is transferred to the Nano phase change energy storage materials, and store them. When the user uses hot water, the nanophase-change energy storage material releases thermal energy to heat the water in the hot water pipe. This device improves the heat transfer performance of the phase change energy storage material, and has a large energy storage density, which accelerates the energy storage and release rate of the phase change material, thereby improving the energy storage efficiency, making the phase change energy storage water heater more energy-saving and more applicable. for extensive.

Description

technical field [0001] The invention belongs to the field of water heaters, and in particular relates to a heat pump water heater of a nano phase change heat storage material. Background technique [0002] Energy is the basis of human existence and the primary issue of economic development. However, with the continuous development of society, the demand for energy continues to increase, and because of the reduction of mineral energy storage, energy conservation has become more and more popular in people's lives. And most of the hot water needed in domestic family daily life is all obtained by special water heater (as electric water heater, gas water heater etc.) at present. These devices exchange high-grade energy for the same amount of low-grade heat, which is not in line with modern energy-saving principles. This makes it very meaningful to research and develop new water heaters to provide domestic hot water with a temperature of 40-50°C for bathing users such as familie...
