Water-phase-change heat storage type solar energy and air energy double-energy-source heating system

Abstract

The invention discloses a water-phase-change heat storage type solar energy and air energy double-energy-source heating system, and belongs to the technical field of energy conservation and environmental protection. The heating system comprises a solar water heater and an indoor heater; the solar water heater is mounted outdoors, the indoor heater is mounted indoors; an air source heat pump is arranged on one side of the solar water heater; a water tank is arranged at the top of the solar water heater; and a heat exchange pipe is mounted in the water tank. According to the heating system, water is used as a phase-change heat storage material, the price is low, environmental protection is achieved, the energy density is large, composite use can be achieved in the heating season, in summer,the solar water heater can be used for providing hot water, the air source heat pump is used for refrigeration, a user can utilize the original solar water heater of a farmer household for modification, thus the initial mounting cost is reduced, the working efficiency of the air source heat pump in severe cold is improved, and the operation cost is reduced; the scheme can be used in a composite mode, independent use is not affected, and the use efficiency is high.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to a water phase change heat storage type solar air energy dual energy heating system. Background technique [0002] In recent years, the state has vigorously promoted the "coal-to-electricity" project, calling on many farmers to no longer use coal for heating in winter, which is not only environmentally friendly and green, but also safer. However, in low temperature and humid environments, the surface of the evaporator of the air source heat pump unit is prone to frost and ice, and the output (energy efficiency ratio) and operation stability of the unit are greatly affected. There are varying degrees of frost and downtime in various regions and northern cold regions, which has affected the popularization and use of air source heat pumps. The air source heat pump technology uses a small amount of electric energy to drive the compressor, obtains en...
