The energy storage heat pump air conditioner can reasonably utilize the peak-valley electricity and reduce the running power fare.

Description

technical field [0001] The invention relates to the technical field of thermal energy conversion and utilization, in particular to an energy storage heat pump air conditioning system for cooling and heating. Background technique [0002] When the heat pump is heating, the heat source is generally the local air, the geothermal heat of the earth, the heat of underground or surface water, the residual waste heat in the production or living process, etc. Among them, the geothermal heat of the earth and the residual waste heat in the production or living process are the most important. Constant, but other heat sources change with time, especially when the air source is used as the heat source of the heat pump, the heating effect of the heat pump is greatly affected by time. [0003] For 24 hours a day, the temperature and humidity of the air will vary with time. During the day, due to direct sunlight, the air temperature and surface temperature are relatively high. At night, ther...

Problems solved by technology

[0010] The purpose of the present invention is to solve the problem that current mainstream heat pumps cannot use peak and valley electricity, reduce the running time of the main engine when the electricity price is high during the day, and the defects in the above-mentioned characteristics, and provide an energy storage heat pump air conditioner, which can store heat by using an energy storage unit and the characteristics of coldness, the characteristics that substances need to absorb or release heat when they are transformed between two phases, that is, the energy storage unit needs to absorb heat when it melts from a solid state to a liquid state, which is the process of storing heat energy; while the energy storage unit condenses from a liquid state to a liquid state. When the solid state needs to release heat, this is the process of storing cold energy (or releasing heat energy); the energy storage heat pump absorbs heat from the atmospheric environment when the ambient temperature is high, and stores the heat energy until the ambient temperature is low. , and then released as the heat source of the heat pump host after being upgraded to meet the needs of production or life and achieve the purpose of heating
