Problems solved by technology

Because solar energy is greatly affected by the weather and has poor continuity, it cannot operate normally in rainy days and nights, thus limiting the application of solar energy in heating or hot water; although air source heat pumps can operate normally and continuously in rainy days or at night, they are not compatible with solar energy. Compared with its energy efficiency is relatively low, the operating cost is relatively high; using electricity alone, the cost is too expensive

Abstract

The invention provides a multifunctional heat supply system and method based on composite energy. The heat supply system comprises an air source heat pump unit, a hot water unit, a solar heat collector, an indoor unit and an electric boiler, wherein the solar heat collector and the air source heat pump unit are connected with the hot water unit, and the hot water unit and the indoor unit are connected with the electric boiler. According to the heat supply system, the solar heat collector, the air source heat pump and the electric boiler are comprehensively applied, indoor continuous heat supply can be realized under different weather and different outdoor temperature conditions, energy is saved, and the cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of energy utilization, and more specifically relates to a multifunctional heating system and method based on composite energy. Background technique [0002] Currently, the heating and cooling air conditioners, heat pump water heaters, and solar collectors on the market are used independently. Because solar energy is greatly affected by the weather and has poor continuity, it cannot operate normally in rainy days and nights, thus limiting the application of solar energy in heating or hot water; although air source heat pumps can operate normally and continuously in rainy days or at night, they are not compatible with solar energy. Compared with its energy efficiency is relatively low, the operating cost is relatively high; using electric energy alone, the cost is too expensive. In the prior art, how to combine solar energy and air source heat pump into an organic system, overcome the defect that sola...
