Multi-energy integrated hot water system

Abstract

The invention discloses a multi-energy integrated hot water system comprising a solar heating device, a fuel gas wall-hanging stove heating device, an air energy heating device, a water tank and a main control unit. A solar heat exchange coil pipe 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-hanging stove heat exchange coil pipe is connected with a water inlet pipe and a water outlet pipe of the fuel gas wall-hanging stove heating device to form a water circulation loop. Condensers of the solar heat exchange coil pipe, the wall-hanging stove heat exchange coil pipe and the air energy heating device are arranged in the water tank. The output end of the main control unit is electrically connected with a solar circulation water pump, an air energy circulation pump and a fuel gas circulation pump. According to the device, by integrating the advantages and making up the defects of a solar water heater, an air energy heat pump water heater and a fuel gas wall-hanging stove water heater, under the condition that water is provided to be used, high efficiency and energy saving are achieved; and meanwhile the fuel gas wall-hanging stove heating device is connected with an underfloor heat exchange system, so that the utilization rate of energy is improved.

Description

technical field [0001] The invention relates to a hot water system, in particular to a multi-energy system integrating solar energy, air energy and gas [0002] Integrated hot water system. Background technique [0003] 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 wall...

Problems solved by technology

[0003] 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.
