Energy storage type absorption adjustable heating and cooling system

Abstract

The invention discloses an energy storage absorption type adjustable heat and cold supply system. The energy storage absorption type adjustable heat and cold supply system comprises a fuse salt heat accumulation system, a circulation system, a heat supply loop system and a cold supply loop system. The heat supply loop system comprises a high-pressure steam preparing circulation loop and a low-pressure steam preparing circulation loop. The high-pressure steam preparing circulation loop comprises a heat exchanger, a heat exchanger outlet channel is connected with a high-pressure steam liquid storage device through a check valve, and a steam outlet pipeline of the high-pressure steam liquid storage device is divided into two channels through an electromagnetic valve. The low-pressure steam preparing circulation loop comprises an absorber connected with a condenser, and an outlet pipeline of the condenser leads to a low-pressure steam liquid storage device after passing through the check valve. A heat accumulation tank is utilized for heating and conducting storage in the power utilization valley, heat is released in the power utilization peak or all-weather situation, the effects of peak moving and valley filling are achieved, dependence on traditional energy can be reduced, the ecological environment is improved, and the environment is protected.

Description

technical field [0001] The invention relates to the technical field of heating, energy storage and refrigeration, in particular to an energy storage type absorption adjustable heating and cooling system. Background technique [0002] Energy is the foundation of human survival and development. The world's energy demand is increasing day by day, energy supply is becoming increasingly tense, and the contradiction between supply and demand is increasing day by day. Today, traditional fossil fuels still play a leading role in energy consumption, and their consumption is huge, and the environmental pollution caused by their combustion has attracted more and more attention. In order to deal with a series of problems brought about by traditional energy sources and climate change issues, the development of new clean energy sources has become an inevitable trend. Our country is implementing the policy of "bringing coal with electricity and oil with electricity". Using coal to electri...

Problems solved by technology

[0004] The traditional energy storage heating system directly exchanges heat between water and molten salt and then passes it into the room for direct heating. It cannot be adjusted according to the heat load required in the room. cause overheating or overcooling

And the efficiency of direct heating is low, which will cause waste of heat

Traditional energy storage systems can only provide heating loads, but cannot create cooling loads, which will cause the energy storage system to be shut down in summer, especially in summer when there is a large difference in peak and valley power consumption, and cannot provide peak-shaving and valley-filling for the summer power grid.

[0005] Generally, there are two ways of waste heat recovery: absorption and adsorption, but the efficiency of the adsorption cycle is very low, and the single-effect efficiency in the absorption cycle is also very low, and the temperature of the generator should not be too high, so the double-effect absorption is generally used. cycle
