Abstract

The invention discloses a hot water type solar energy and air energy combined heat and power generation integrated system which comprises a water storage box, a first water pump, a solar heat collector, a low-position side heat exchanger, a compression and expansion difunctional machine head, a permanent magnet electric power generation integrated motor, a high-position side heat exchanger, an expansion valve, a working medium pump and a second water pump. Air cooling is adopted by the low-position side heat exchanger, one port of a low-position side heat exchanger working medium side passes through the compression and expansion difunctional machine head to be connected to one port of a high-position side heat exchanger working medium side, two bypasses are connected to the other port of the high-position side heat exchanger working medium side and the other port of the low-position side heat exchanger working medium side in parallel, opening or closing of the valve is adjusted, solarenergy and air energy can achieve heating in the heating period and power generation in the non-heating period, and the building requirement for hot water supplying all year around is met; the air source heat pump cost is low, installation is simple, the energy efficiency is high, environmental protection is achieved, the preheating time is short, the indoor temperature requirement can be quicklymet, and the hot water type solar energy and air energy combined heat and power generation integrated system is suitable for supplementary heat sources of a solar heating system.

Description

technical field [0001] The invention belongs to the technical field of solar air energy utilization, and in particular relates to a hot water type solar air energy combined heat and power integrated system. Background technique [0002] In recent years, with the continuous development of urbanization and the continuous improvement of people's requirements for the comfort of living and working environments, the construction industry has ushered in the rapid growth, and building energy consumption has shown a continuous upward trend. Heating in winter in northern regions is the main component of building energy consumption. As of 2016, the total heating area of ​​urban and rural buildings in northern my country is about 20.6 billion square meters. Among them, the heating area of ​​urban buildings is 14.1 billion square meters, and the heating area of ​​rural buildings is 6.5 billion square meters. The energy used for heating in northern my country is mainly coal-fired, and t...
