Multi-energy complementary heat supply system applied to independent heating supply system

Abstract

The invention discloses a multi-energy complementary heat supply system applied to an independent heating supply system. The multi-energy complementary heat supply system comprises a heat supply unit, a heat storage unit and heat taking units. The heat supply unit comprises a solar heat collection system, an air source heat pump system and a gas heating water heater system, the heat storage unit uses a heat storage system with an upper coiled tube and a lower coiled tube, and the heat taking units are a domestic hot water system and a heating system respectively; the solar heat collection system is connected with the lower heat exchange coiled tube of the heat storage system with the upper coiled tube and the lower coiled tube; the air source heat pump system is directly connected with a water inlet-outlet port in the middle part of the heat storage system with the upper coiled tube and the lower coiled tube; the domestic hot water system is connected with an upper water inlet-outlet port and a lower water inlet-outlet port of the heat storage system with the upper coiled tube and the lower coiled tube through a gas heating water heater; and the heating water system is connected with the upper heat exchange coiled tube of the heat storage system with the upper coiled tube and the lower coiled tube through the gas heating water heater. The multi-energy complementary heat supply system disclosed by the invention uses many kinds of energy for realizing complementary heat supply, increases the heat efficiency of the system and the utilization efficiency of the energy, reduces the discharge of pollutants, and increases the integration degree of the device.

Description

technical field

[0001] The invention relates to a heating device, in particular to a multi-energy complementary heating system and process applied to an independent heating system. Background technique

[0002] In recent years, my country's building energy consumption accounts for about 30% of the country's total energy consumption, of which urban heating energy consumption in northern regions accounts for 36% of the country's total urban building energy consumption. 15% to 20% of the total energy consumption. Most of the traditional decentralized heating systems consume non-renewable energy and cause serious pollution, resulting in frequent smog in winter. Gas heating water heaters can provide heating and domestic hot water conveniently and quickly, while air source heat pump systems and solar collectors can provide people with heating and domestic hot water at low cost. If the gas heating water heater is used alone for heating, the energy density is high, and the user loa...
