Distributed energy resource station absorption type cold storage and heat storage dual-purpose energy storer

Abstract

The invention relates to a distributed energy resource station absorption type cold storage and heat storage dual-purpose energy storer. The energy storer comprises a heat exchanger with dual uses of a condenser and an evaporator, a heat exchanger with dual-use of a reactor and a absorber, a cooling agent storage tank and an absorbing agent storage tank, wherein a thermal separation baffle is used for separating the bottoms of the heat exchanger with the dual uses of the condenser and the evaporator and the heat exchanger with the dual uses of the reactor and the absorber, the upper portions of the heat exchanger with the dual uses of the condenser and the evaporator and the heat exchanger with the dual uses of the reactor and the absorber are communicated with each other, heat exchange tubes of the two heat exchangers are each communicated with a piping system of the distributed energy resource station through pipelines, the cooling agent storage tank is connected with the heat exchanger with the dual uses of the condenser and the evaporator to form a circulation loop through pipelines, and the absorbing agent storage tank is connected with the heat exchanger with the dual uses of the reactor and the absorber to form a circulation loop through pipelines. Compared with the prior art, by means of a absorption heat chemical reaction, energy storage of waste heat of distributed energy resource station generator sets is achieved; when cold supply is needed, cooling quantity is released; when heat supply is needed, heat quantity is released. Accordingly, a function with dual uses of accumulation of cold and accumulation of heat is achieved.

Description

technical field [0001] The invention relates to an energy storage device, in particular to an absorption type dual-purpose energy storage device for cold storage and heat storage in a distributed energy station. Background technique [0002] Distributed energy station, commonly known as combined cooling, heating and power supply system, refers to a comprehensive energy utilization system distributed at the user end. The primary energy is mainly gaseous fuel, supplemented by renewable energy, using all available resources; the secondary energy is mainly distributed in the heat, power, cooling (plant) cogeneration at the user end, supplemented by other central energy supply systems, to achieve direct Cascade utilization of energy to meet the various needs of users, and provide support and supplementation through the central energy supply system; in terms of environmental protection, part of the pollution will be dispersed and resourced, and strive to achieve the goal of modera...

Problems solved by technology

However, the existing sensible heat storage and latent heat storage equipment still have the following deficiencies in practical application: 1. It is difficult for the traditional energy storage device to store cold and heat at the same time, and the initial investment of the energy storage device is relatively large; 2. The heat storage equipment occupies a large space; 3. The heat dissipation loss during the heat storage process is relatively large
