Multi-energy integrated water heating system

Abstract

The invention discloses a multi-energy integrated water heating system, which comprises a solar heating device, a wall-hung gas boiler heating device, an air energy heating device, a water tank and a master control unit. A solar heat exchange pipe coil is connected with a water inlet pipe and a water outlet pipe of a solar water collector to form a water circulation loop. A wall-hung boiler heat exchange pipe coil is connected with a water inlet pipe and a water outlet pipe of the wall-hung gas boiler heating device to form a water circulation loop. The solar heat exchange pipe coil, the wall-hung boiler heat exchange pipe coil and a condenser of the air energy heating device are arranged in the water tank. The output end of the master control unit is electrically connected with a solar circulating water pump, an air energy circulating pump and a gas circulating pump. According to the system, the advantages of a solar water heater, an air energy heat pump water heater and a wall-hung gas boiler water heater are integrated, and the shortcomings of the solar water heater, the air energy heat pump water heater and the wall-hung gas boiler water heater are overcome, so that the system is efficient and energy-saving under the condition of ensuring the use of hot water; and in addition, the wall-hung gas boiler heating device is connected with a floor heating heat exchange system, so that the utilization rate of energy is increased.

Description

technical field [0001] The invention relates to a hot water system, in particular to a multi-energy integrated hot water system which integrates and utilizes solar energy, air energy and gas. Background technique [0002] Both solar energy and air energy are inexhaustible energy sources, and they will not pollute the environment. However, traditional solar water heaters cannot work without the sun. Although there are solar water heaters with auxiliary electric heating function, However, it consumes more power, and the electric heating device is placed in water for a long time, which may easily cause safety hazards such as electric leakage; the air energy heat pump water heater is a water heater that uses a compressor to convert low-temperature heat energy in the air into high-temperature heat energy to make hot water. High efficiency and energy saving are second only to solar water heaters, but they cannot work when the temperature is very low. At present, the gas-fired wal...

Problems solved by technology

[0002] Both solar energy and air energy are inexhaustible energy sources, and they will not pollute the environment. However, traditional solar water heaters cannot work without the sun. Although there are solar water heaters with auxiliary electric heating function, However, it consumes more power, and the electric heating device is placed in water for a long time, which may easily cause safety hazards such as electric leakage; the air energy heat pump water heater is a water heater that uses a compressor to convert low-temperature heat energy in the air into high-temperature heat energy to make hot water. High energy efficiency is second only to solar water heaters, but it cannot work when the temperature is very low

At present, gas-fired wall-hung boiler water heaters are widely used because they use gas as energy, and their work is not limited by natural environmental conditions, and continuous supply can be achieved. However, gas is a non-renewable resource and the cost of use is high.
