Novel combined energy supplying system

Abstract

The invention discloses a novel energy supplying system which comprises a plurality of ground source heat pump units, an energy storage tank, a cooling tower and a plate type heat exchanger, wherein an energy-storing type heat exchange pipeline with one end connected with the energy storage tank is connected with a pipeline on one side of a plate type heat exchanger, a tenth valve is installed on the heat exchange pipeline of the energy storage tank on the outlet side of the pipeline on one side of the plate type heat exchanger, an inlet of the energy storage tank is connected with a water return pipeline of the energy storage tank where a ninth valve and a plate exchanging primary side circulating pump are sequentially installed, an inlet end of the pipeline on the other side of the plate type heat exchanger is connected with a water collector through a user return water pipeline where fourth valves are installed sequentially, and an outlet end of the pipeline on the other side of the plate type heat exchanger is connected with a water distributor and a user water supply pipeline where a plate exchanging secondary side circulating pump and a thirteen valve are installed. By adopting the novel energy supplying system, heat and cold energy manufactured by a ground source heat pump can be stored in the energy storage tank which can discharge the energy at the peak period of electricity price at day time.

Description

technical field [0001] The invention relates to the technical field of high-efficiency utilization of renewable energy, in particular to an energy supply system. Background technique [0002] my country's building energy consumption accounts for 27.5% of the total energy consumption in the country. With the improvement of people's living standards, this proportion will further increase. It is estimated that by 2030, it will rise to 40%. Among them, the energy consumption for building heating and air conditioning is the “big energy consumer” of buildings. The energy consumption of air conditioning in large public buildings generally accounts for 40% to 60% of the total energy consumption of buildings. Therefore, it is of great significance to explore energy-saving and environmentally friendly heating and cooling technologies important practical significance. In my country, most of the heating and heating of buildings is obtained by directly burning fossil fuels such as coal,...

Problems solved by technology

However, the most widely used ground source heat pump technology currently adopts the synchronous operation mode of day and night. Due to the functional characteristics of office buildings, the heating and air conditioning loads are mainly concentrated during the working hours during the day, and the cooling and heating loads in other time periods are relatively small. If the heat pump operates synchronously as a heat source or a cold source, since the daytime is the peak time of electricity consumption and the electricity price is high, the cost of heating and cooling will inevitably be higher
