Solar heat accumulation and solar heating low-melting-point paraffin bathing device

Abstract

The invention discloses a solar heat accumulation and solar heating low-melting-point paraffin bathing device. The bathing device comprises a heat accumulation box (6), a solar energy supply pipeline (27) which supplies solar heat energy to the heat accumulation box (6), a heating pipeline (28) for heating, and a bathing pipeline (29) for bathing. A shell of the heat accumulation box (6) is of a dual-layer structure composed of an inner container (20) and an outer shell (22), a heat preservation polyurethane layer (21) is arranged between the inner container (20) and the outer shell (22), and the heat accumulation box is filled with low-melting-point paraffin (13). A first heat exchanger (11), a second heat exchanger (23) and a third heat exchanger (24) are sequentially arrayed in the heat accumulation box. Paraffin with the melting point ranging from 35 DEG C to 44 DEG C serves as a heat accumulation medium, the heat accumulation capacity of the heat accumulation box is 3 times to 6 times that of a water tank which is the same as the heat accumulation box in size, namely, volume, and more heat energy can be stored.

Description

technical field [0001] The invention belongs to the technical field of solar energy, and in particular the invention relates to a low melting point paraffin solar heat storage heating bathing device. Background technique [0002] Existing heating needs to consume a lot of coal, natural gas, and electric energy resources. Today, when energy conservation and emission reduction are vigorously advocated, solar energy is free energy, inexhaustible, and inexhaustible, but solar energy is also an unstable energy source. 2. There is a problem of unbalanced utilization at night, which directly affects the effect of solar heating. Therefore, to achieve heating during the day and use at night, energy storage is the key. If solar heating is used for heating, water is used as the heat storage medium, which uses the rise of water temperature (sensible heat) to store heat, so the heat storage capacity is very low, and as the water temperature rises, the heat lost is also relatively small....

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a low-melting point paraffin solar heat storage heating bathing device. The low melting point paraffin solar heat storage heating bathing device of the present invention uses paraffin wax with a melting point range of 35°C-44°C as the heat storage medium. The heat capacity is 3-6 times that of the water tank of the same size (referring to the same volume of the heat storage tank), which can store more heat for use at night and in rainy days; it completely solves the problem of poor thermal conductivity and fluidity of phase change materials question
