specific Embodiment approach 1

[0028] Specific implementation mode one: combine figure 1 Explain that the solar heat collection and ventilation system for passive houses in this embodiment includes a passive solar house 1, a transparent glass cover plate 5, a solar chimney air interlayer 6, and a heat storage tank 10; the passive solar house 1 includes a heavy wall 9. 16 and 17 inside the passive room; a heat absorbing plate 7 is arranged near the side of the heavy wall 9 .

[0029] The transparent glass cover plate 5 of the present embodiment is provided with damper 1 (12-1), damper 2 (12-2), damper 3 (12-3), damper 4 (12-4), heavy wall 9 The upper and lower sides are respectively provided with indoor air inlets 11-1, 11-3 and indoor air outlets 11-2, 11-4.

specific Embodiment approach 2

[0030] Specific implementation mode two: combination Figure 1-Figure 2 Description, the hot water storage tank 10 in this embodiment is connected with the passive house through the hot water inlet pipe 14-1, the cold water outlet pipe 14-2, the outlet pipe valve 8 (15-2), the water inlet pipe valve 7 (15-1) and the passive house. The interior 17 on the second floor is connected to the interior 16 on the first floor of the passive house.

specific Embodiment approach 3

[0031] Specific implementation mode three: combination figure 1 To illustrate, the transparent glass cover plate 5 in this embodiment is double-layer insulating glass or PC solar panels. The heat collection and ventilation effect is good, the construction process is simple, and the cost is low. Others are the same as in the first embodiment.

[0032] The working modes provided by the present invention under four typical working conditions in winter and summer will be described below in conjunction with the accompanying drawings.

[0033] Depend on figure 2 It can be seen that the passive heating and ventilation system of the solar chimney coupled with the separated heat pipe provided by the present invention, the winter operation mode is: winter heating mode, the indoor air inlets 11-1, 11-3 are opened, and the indoor air outlets 11-2, 11- 4. Close damper 1 (12-1), damper 2 (12-2), damper 3 (12-3) and damper 4 (12-4) simultaneously. Affected by solar radiation, the heat a...

Abstract

The invention discloses a passive heating and ventilation system for coupling a solar chimney and a separated type heat pipe. The passive heating and ventilation system is composed of four subsystemsincluding a passive solar house, the solar chimney, the separated type heat pipe and domestic hot water. The passive house is a two-storey or multi-storey building; the solar chimney includes a double-layer transparent glass cover plate, an air interlayer, a heavy wall, an air valve, an air inlet, an air outlet and a heat absorbing plate; and the separated heat pipe is composed of an evaporator, acondenser, a rising air pipe, a descending liquid pipe and a control valve. The passive heating and ventilation system can overcome the shortcomings that a traditional passive solar house heating andventilation system is single in function and low in efficiency, causes overheating in summer and the like, and has the advantages of the good heating and ventilation effect, the various functions, the large use range and the improvement of the indoor thermal environment. Heat can be dissipated to the outside in summer to prevent indoor overheating caused by the solar chimney, meanwhile, domestichot water is produced, and the heating effect can be maximized in winter.

Description

[0001] Technical field [0002] The invention relates to a passive solar heat utilization technology, which belongs to the technical field of solar energy, in particular to a passive heat supply and ventilation system in which a solar chimney is coupled with a separated heat pipe. Background technique [0003] With the advancement of urbanization, the demand for energy in urban areas has increased sharply, and the environmental problems caused by energy consumption have become increasingly serious. Due to the level of economic development, there is a huge problem of building energy consumption in villages and towns. Making full use of renewable energy to reduce building energy consumption and create a comfortable and healthy thermal environment has become one of the main directions for the development of the HVAC industry. [0004] Solar chimneys can be used for passive solar hot air heating and natural ventilation cooling, which can effectively reduce the energy consumption ...
