Abstract

The invention discloses a new energy cross-season energy storage heating system combining a water source heat pump and an air source heat pump. The new energy cross-season energy storage heating system comprises the water source heat pump, a cross-season energy storage device, the air source heat pump, a heating circulating pump and a heating pipeline. The heating pipeline is used for being connected with return water of a heating user, the heating pipeline sequentially passes through the heating circulating pump, the air source heat pump and the hot water end of the water source heat pump, and the heating pipeline is further used for being connected with feed water of the heating user. The system has the technical effects that the low energy efficiency of a pure electric heating system is avoided, the problem that the heating quality of a pure air source heat pump system is difficult to guarantee is avoided, the electricity quantity of abandoned electricity in non-heating seasons and the high energy efficiency of high-temperature weather are fully utilized, and the purposes of absorbing the electricity quantity of the abandoned electricity and reducing electric energy consumption are achieved.

Description

technical field [0001] The invention relates to the technical field of new energy energy storage heating, in particular to a new energy cross-season energy storage heating system combining a water source heat pump and an air source heat pump. Background technique [0002] Of the coal consumed in my country every year, 1 / 2 is used for power generation, and 1 / 4 is used for the production of industrial steam, hot water or hot air. This 1 / 4 of the coal discharges 45% of the total amount of dust and 37% of the total amount of sulfur dioxide, causing huge The pollution is mainly used for central heating in northern areas. The replacement of coal-fired heating with new energy is the general trend. However, new energy has very high uncontrollability and volatility. When it is used for heating, it is necessary to configure an energy storage device to offset its volatility and uncontrollability. At the same time, heating has a strong seasonality. It is not economically feasible to bu...
