The invention discloses a multi-class heating power unit energy storage interconnection system and an automatic energy storage heating control method. The multi-class heating power unit energy storageinterconnection system involves a first medium source heating power unit (1), a second medium source heating power unit (5), an energy storage unit (9) and an end device (12), wherein the first medium source heating power unit (1), the second medium source heating power unit (5) and the end device (12) are sequentially connected in series through a water supply pipeline and a water return pipeline, and the energy storage unit (9) is connected in parallel between the water supply pipeline and the water return pipeline of the second medium source heat unit (5) and the end device (12). Accordingto the multi-class heating power unit energy storage interconnection system, through the energy storage and unit optimization coordination control, the electricity capacity-increase capacity of the whole system can be reduced, so that the investment is reduced, the low efficiency of an air source heat pump under the cold condition is improved, and the full utilization of the electricity price inthe low-electricity-price period is realized.
Description
technical field [0001] The invention relates to the technical field of heating, in particular to a multi-type thermal unit energy storage interconnection system and an automatic energy storage heating control method. Background technique [0002] In the prior art, heating and hot water supply by means of burning coal or gas will bring relatively serious environmental pollution. It is cleaner to use electric heat pump instead of coal and gas, and it is more efficient than direct electric heating such as electric boiler and heating cable. Using a simple air source heat pump for heating, in cold conditions, the efficiency of the air source heat pump will drop very low, and the outlet water temperature will not meet the requirements of the equipment with radiators at the end, so that the expected heating effect cannot be achieved, and the cost will increase significantly. [0003] However, the existing energy storage heat pump system has the following problems in practical appl...
