Abstract

The invention discloses a complementary heat pump air-conditioning system based on multiple renewable energy resources, which belongs to the field of heat pump air-conditioning. The system is characterized in that a solar thermal collector is simultaneously connected with a constant-temperature anaerobic fermentation device and a low-temperature water tank; the constant-temperature anaerobic fermentation device is sequentially connected with an air compression device, a purification device and a gas storage device; the gas storage device is sequentially connected with a marsh gas water heater and a gas port A for a user to use; a hot water port of marsh gas water heater is simultaneously connected with the low-temperature water tank, a first hot water port B and a first backwater port C; the low-temperature water tank is provided with a second hot water port D and a second backwater port E; an outdoor air-cooling type heat exchanger and a heat exchanger in the low-temperature water tank are connected in parallel; the outdoor air-cooling-type heat exchanger and a heat exchanger in a moderate-temperature water tank are connected in parallel; and the moderate-temperature water tank is provided with a third hot water port F and a third backwater port G.

Description

technical field

[0001] The invention relates to a building heat pump air conditioning system. Background technique

[0002] In my country, building energy consumption accounts for more than 20% of the country's total energy consumption, while heating and air conditioning energy consumption accounts for about 2 / 3 of building energy consumption. Adopting advanced heat pump energy-saving technology combined with biomass anaerobic fermentation technology to solve users' needs for heating in winter, cooling in summer, domestic hot water and gas consumption throughout the year is a better way to solve this part of energy demand.

[0003] According to different low-temperature heat sources, vapor compression heat pump air-conditioning systems are generally divided into air source, solar energy, water source, soil source heat pump and other types. The air source heat pump air conditioner unit has been greatly developed and widely used in recent years because of its characteristics ...
