Embodiment 1

[0031] Such as figure 1 As shown, the low-melting point paraffin solar heat storage heating bathing device includes a heat storage tank 6, and a solar energy supply pipeline 27 for providing solar heat energy for the heat storage tank 6 and including a first heat exchanger 11, for Heating pipeline 28 for heating and including the second heat exchanger 23 , and bathing pipeline 29 for bathing and including the third heat exchanger 24 . Wherein, the housing of the heat storage box 6 is a double-layer structure composed of an inner tank 20 and an outer shell 22, and a polyurethane insulation layer 21 is provided between the inner tank 20 and the outer shell 22; the inside of the heat storage tank is filled with Paraffin wax 13 with a melting point of 35° C.; and the first heat exchanger 11 , the second heat exchanger 23 and the third heat exchanger 24 are sequentially arranged inside the heat storage tank.

[0032] The first heat exchanger 11 , the second heat exchanger 23 and t...

Embodiment 2

[0044] This embodiment is basically the same as Embodiment 1, the only difference being that the melting point of the low-melting paraffin 13 filled in the heat storage tank is 42°C, and the heat storage tank is also filled with water. Both the paraffin and water are filled into the heat storage tank at 25°C; and the volume ratio of the low melting point paraffin and water filled in the heat storage tank is 2:1.

[0045] Since the heat storage tank is filled with low melting point paraffin and water with a volume ratio of 2:1, the thermal conductivity and flow performance of the heat storage material are further improved; thereby further improving the low melting point paraffin solar heat storage heating of the present invention. The heat storage capacity of the 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....
