Description

Energy storage method and energy storage device implementing the method

technical field

The invention relates to energy storage technology, in particular to an energy storage method and an energy storage device implementing the method.

Background technique

With the rapid development of my country's social economy and the continuous improvement of people's living standards, the demand for heating, cooling and air conditioning continues to rise, resulting in an increase in building energy consumption. At present, building energy consumption has exceeded 1/4 of the national energy consumption, and building energy conservation is imperative. Therefore, large-scale utilization of natural environmental protection energy and solving the problem of building energy conservation are important ways to promote the development of circular economy.

Air source equipment has begun to be popularized in my country due to its high energy efficiency ratio, high safety, no weather restrictions, all-weather work, and the most energy-saving advantages. The air source equipment uses the heat-absorbing medium (refrigerant) in the equipment to collect heat energy from the air or the natural environment, and quickly raises the temperature of the cold water through the heat exchanger, and emits cold air at the same time. It avoids the defect that traditional solar products cannot work in rainy weather and at night. As long as the outside temperature is above -15°C, it can work normally, so it can be more efficient, environmentally friendly and energy-saving. At the same time, it does not occupy open space. It is easy to install and flexible to use. For this reason, people use this technical principle to develop the air source hot water unit.

Therefore, during the day, due to the high temperature, the air source equipment can generate relatively sufficient heat or cold energy. However, people usually only start to need hot or cold baths at night. Because the structure of the existing energy storage device is complicated, the volume is large, and the energy storage effect is poor. As a result, it cannot be applied to air source hot water units, resulting in no energy storage function in the existing air source hot water units, resulting in the heat energy generated by the air source heat pump unit during the day and the cold energy of the cold air discharged when generating heat energy Wasted in vain, causing unnecessary waste of energy, is not conducive to energy conservation and environmental protection.
