Solar energy-water source heat pump heating system capable of taking heat by depending on solar energy and phase changes

Abstract

The invention discloses a solar energy-water source heat pump heating system capable of taking heat by depending on solar energy and phase changes. The system is applied to the field of heating and comprises a first coil pipe and a second coil pipe which are arranged in a water tank, a water outlet of the first coil pipe is connected with a water inlet of a water source heat pump through a fifth pipeline, a water outlet of the water source heat pump is connected with a water inlet of the first coil pipe through a sixth pipeline, the water source heat pump is connected with a heat user, a water inlet of the second coil pipe arranged below the first coil pipe is connected with a water outlet of a solar heat collection plate through a first pipeline, and a water inlet of the solar heat collection plate is connected with a water outlet of the second coil pipe through a second pipeline. By means of the system, heat released by solar energy and heat released by water phase changes are perfectly combined for the first time, stable heating in the daytime and at night is achieved, and the system is energy-saving, environmentally friendly, high in energy utilization rate, good in operation performance, low in maintenance cost and free of pollutant emission, has a brand-new design concept, opens up a new thought for energy development and utilization and is necessary for popularization.

Description

technical field [0001] The invention relates to the field of solar heating, in particular to a solar-water source heat pump heating system relying on solar energy and phase change to obtain heat. Background technique [0002] In recent years, with the continuous development and use of non-renewable resources around the world, the trend of energy shortage is inevitable, and the problem of non-renewable energy consumption has become increasingly serious. Countries have sought the development and utilization of renewable energy, and looked for effective and usable sustainable energy, such as Solar energy, wind energy, etc. [0003] Solar energy is clean and environmentally friendly, without any pollution, and has high utilization value, while the water source heat pump is a heat raising device that can convert low-level heat energy in water into high-grade heat energy. The combination of the two is the best choice for heating users. However, the sun's radiation is limited by ...

AI Technical Summary

Problems solved by technology

However, the solar radiation is limited by natural conditions such as day and night, seasons, and weather, resulting in intermittent and unstable heating devices, which cannot meet the heating requirements of users.

[0004] At present, most of the vacuum tube solar collectors are used, the initial installation cost is high, and the return pipe is easy to freeze and be damaged in the cold winter, which affects the normal use of the equipment. The existence of the above problems makes solar heating unable to be widely used.
