Air-source heat pump water heater powered by wind-solar complementary power generation system

Abstract

The invention relates to an air-source heat pump water heater powered by a wind-solar complementary power generation system, and belongs to the technical field of clean energy application. Sunlight irradiates a solar battery to generate current which is inputted to a junction station through a conductor wire, a photovoltaic controller and a photovoltaic inverter, wind power blows blades to rotate, a wind driven generator is driven to generate current which is inputted to the junction station through a conductor wire and a wind power controller, the current outputted from the junction station is inputted to a compressor through a conductor wire to serve as driving power, rotation of the compressor drives refrigerants to continuously circulate in a system, the refrigerants evaporate and absorb heat energy in air in an evaporator, so that liquid refrigerants are changed into gaseous refrigerants, the gaseous refrigerants enter a condenser, then release high-temperature heat energy to heat water and are cooled into the liquid refrigerants, and photovoltaic current and wind power current are collected in the junction station to serve as the driving power for driving the air-source heat pump water heater to generate a large amount of hot water supplied to users. The air-source heat pump water heater generates the hot water without burning coal, so that the environments are protected, and energy is saved.

Description

technical field [0001] The invention relates to an air source heat pump water heater powered by a wind-solar complementary power generation system, and belongs to the technical field of clean energy applications. Background technique [0002] On January 17, 2014, the first day of the Spring Festival travel season, Beijing experienced its first severe smog this year, with PM2.5 concentrations exceeding 500 micrograms per cubic meter. During the 31 days in January 2014, there were two obvious heavy air pollution processes in Beijing, and there were as many as 26 days of smog. Persistent smog has affected air quality and human health, and the mortality rates of acute cases, respiratory diseases, and cardiovascular diseases among the population have increased significantly. On February 20, 2014, Beijing launched the emergency measures of "orange warning" for air pollution for the first time, recommending that primary and secondary schools and kindergartens stop outdoor activiti...

Problems solved by technology

[0003] Existing air source heat pump water heaters completely rely on the power supply in the power supply network to supply electricity through conductive wires. At present, the electricity in the power supply network in eastern China mainly comes from burning coal for power generation. More power consumption means more coal burning, which is not conducive to controlling combustion The total amount of coal, the long-term burning of too much coal is the main reason for the continuous occurrence of smog
