Description

technical field [0001] The invention relates to a hot water bathing and heating system, in particular to a parallel superconducting solar heat pump hot water bathing and heating system. Background technique [0002] At present, gas water heaters, coal-fired water heaters, electric water heaters, air source heat pump water heaters, water source heat pump water heaters, and solar water heaters are widely used for hot water bathing and heating. It is extremely uneconomical to heat cold water with gas, coal, and electric water heaters for bathing and heating. For example, gas water heaters have an actual heating coefficient of only 0.5 to 0.7 due to high-temperature exhaust gas emissions, incomplete combustion, forced smoke exhaust, and heat transfer efficiency losses; coal-fired hot water has a heating coefficient of only 0.4, and electricity The heating coefficient of the water heater for heating hot water is only 0.85, while that of the heat pump is as high as 5.6. Therefore...

Problems solved by technology

However, there are certain limitations in the use of ground source heat pumps, such as: the soil thermal conductivity is small, and the heat exchange intensity is small, which is limited by the actual application site; especially, the heat pump continuously extracts heat (or heat storage) from the soil for a long time. The temperature field of the soil will not be effectively restored for a long time, resulting in the continuous decrease (or increase) of the soil temperature, which not only reduces the COP value of the heat pump unit, but also makes the heat pump operation work less Unstable

Solar energy is a kind of green low-grade energy. The use of ordinary solar energy for bathing and heating can save energy significantly, but it is limited by weather conditions, operating conditions and heating efficiency. It is difficult to take advantage of solar energy when the irradiance is very low

Moreover, the use of solar heating requires quite a lot of heat collecting plates or heat collecting tubes, which occupy a large area. It is difficult to use solar heating for high-rise and small high-rise buildings. To heat, it is necessary to install a high-power auxiliary heat source on the energy storage.

At present, electric heat pipes are used as the auxiliary heat source of solar energy storage, the heat conversion efficiency is low, and the power consumption is large, which is unacceptable to users, and the household wires cannot afford it.
