An energy supply system capable of realizing grid-scale peak regulation

Abstract

The invention provides an energy supply system capable of realizing grid-scale peak regulation, which includes a water heater, and is characterized in that it also includes a household-type spiral coil heat exchanger, an economical waste heat recovery device, a heat storage device, a billing controller, and a temperature increasing valve. , Liquid-phase main pipe controller, vapor-phase main pipe controller, the present invention adopts the evaporator for recovery of waste heat of refrigerant condensate, utilizes my country's rich night-time low-valley electricity, absorbs air energy, and obtains heat energy several times the relative power consumption and stores it in underground storage The heat pool uses the energy in a staggered peak period, which greatly reduces the power consumption tension in urban and rural areas. It does not require expensive frequency conversion compressors and frequency conversion control boards. Each household only needs a simple and cheap household spiral coil heat exchanger. The indoor unit adopts a wall-type radiant heater, and the energy consumption of the whole machine is small. In particular, it can provide domestic hot water, which brings cheap, convenient and clean energy consumption to the rural people in towns and villages. The best choice for air environment.

Description

technical field [0001] The invention belongs to building energy saving, relates to electric energy storage and utilization, relates to the shortage of power supply in urban peak periods, and in particular relates to an energy storage air conditioner and hot water system capable of realizing grid-scale peak regulation. Background technique [0002] my country is a large coal-fired thermal power generation country. Since thermal power generation cannot be started or stopped at will like gas-fired power generation, it leads to a serious waste of low-peak electricity at night in our country, and at the same time makes our country’s renewable energy power unable to connect to the grid at night. , seriously impeding the development of renewable energy. How to create a huge, cheap, long-life, and controllable energy storage and peak-shaving system is a major problem that needs to be solved urgently in the energy field of our country. On the one hand, a large amount of power is waste...

[0002] my country is a large coal-fired thermal power generation country. Since thermal power generation cannot be started or stopped at will like gas-fired power generation, it leads to a serious waste of low-peak electricity at night in our country, and at the same time makes our country’s renewable energy power unable to connect to the grid at night. , seriously impeding the development of renewable energy

How to create a huge, cheap, long-life, and controllable energy storage and peak-shaving system is a major problem that needs to be solved urgently in the energy field of our country. On the one hand, a large amount of power is wasted in the low-power valley, and the wind is seriously abandoned; on the other hand, the peak power consumption of cities The peak power consumption of air-conditioning accounts for only 5% of the whole year, and the country spends hundreds of billions of dollars every year to expand capacity. There are also cities and villages where people need domestic hot water. A large amount of foreign exchange is used to buy natural gas, especially in towns and rural areas. It costs more than 2 yuan to take a bath with canned liquefied gas in winter, while air-energy water heaters on the market are too expensive, and it costs more than 5,000 yuan to install one. Air conditioners consume a lot of energy and are expensive. People hope to have energy-consuming products that are low in energy consumption, cheap and good in quality, and can provide hot water in four seasons.
