Description

Underground heat exchange type water-through heat-preservation wooden outer wall

Technical Field

The utility model relates to a building energy saving field especially relates to an underground heat transfer formula leads to water heat preservation wood system outer wall.

Background

Although the traditional building adopts certain heat preservation measures on the outer wall, the heat preservation performance of the building in winter is improved to a certain extent. However, in the winter heating period of severe cold areas, the concrete structure has poor heat insulation effect. In order to achieve the expected heat insulation effect, the thicknesses of the outer wall and the heat insulation material must be increased, so that the building cost is increased, and the later use effect does not necessarily meet the expected requirement.

Disclosure of Invention

The utility model aims at overcoming prior art's shortcoming, providing one kind can reduce indoor heat dissipation, reinforcing indoor heat preservation effect, improves building energy conservation's ultralow energy consumption underground heat transfer formula logical water heat preservation wood system outer wall.

The utility model provides an underground heat exchange type water-through heat-preservation wooden outer wall, which comprises an outer side foam polyurethane layer, an outer side extrusion molding heat preservation plate layer, a hollow layer, a wooden main body, an inner side extrusion molding heat preservation plate layer and an inner side foam polyurethane layer from outside to inside in sequence; the outer wall of the polyurethane layer is coated with a waterproof coating, and the outer wall of the inner side foam polyurethane layer is coated with an inner side decorative coating;

the hollow layers of the outer wall of the house are respectively provided with a water pipeline distributed in a snake shape; the water pipeline is fixed on the wooden main body by adopting a fastener; the water pipeline in each outer wall is independently arranged; the water inlet end of each water pipeline is communicated with a water supply and distribution vertical pipe, and the water outlet end of each water pipeline is communicated with a water return and collection vertical pipe; the water inlet of the water supply and diversion vertical pipe is communicated with the water outlet of the water pump through a water inlet main pipe, and the water inlet of the water pump is connected with the outlet of a heat exchange pipe of the underground heat exchange device through a pipeline; and the inlet of the heat exchange tube of the underground heat exchange device is connected with the water return water collecting vertical tube through the water return main tube.

The utility model has the effects that:

the roof and the outer wall are arranged by a wood processing method, so that the safety of a building can be ensured to the greatest extent; through to wood system roof and wood system outer wall spraying foam polyurethane layer with set up extrusion molding insulation board layer, can furthest promote the thermal insulation performance of roof and outer wall, reduce the energy resource consumption of building, maintain indoor constant temperature state simultaneously, guarantee the indoor personnel travelling comfort.

The water pipes arranged on the integral outer wall and the roof are connected with an underground heat exchange device outside the house to form a small hot water circulation; by using the hot water circulation, the heat exchange between the outer wall of the building in the severe cold area and the outside during the heat supply in winter is reduced, the heat dissipation capacity of the building is reduced, the indoor temperature and the comfort are improved, and the energy-saving effect of the building in the severe cold area is enhanced.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in the attached drawings, the wooden outer wall 2 of the underground heat exchange type water-through heat-preservation wooden outer wall of the utility model comprises an outer side foam polyurethane layer 13, an outer side extrusion molding heat-preservation plate layer 12, a hollow layer 11, a wooden main body 9, an inner side extrusion molding heat-preservation plate layer 15 and an inner side foam polyurethane layer 16 from outside to inside in sequence; the outer wall of the polyurethane layer 13 is coated with a waterproof coating 14, and the outer wall of the inner side foam polyurethane layer 16 is coated with an inner side decorative coating 17.

The waterproof coating 14, the outer side foam polyurethane layer 13, the outer side extrusion molding heat preservation plate layer 12, the inner side extrusion molding heat preservation plate layer 15, the inner side foam polyurethane layer 16 and the inner side decorative coating 17 adopt the existing products on the market; the wooden body 9 is treated to be fireproof, moisture-proof, insect-proof and antiseptic.

The hollow layers 11 of the outer wall of the house are respectively provided with water pipelines 10 distributed in a snake shape; the water pipeline 10 is fixed on the wooden main body 9 by adopting a fastener; the water pipeline 10 in each outer wall is independently arranged; the water inlet end of each water pipeline 10 is communicated with a water supply and distribution vertical pipe 7, and the water outlet end of each water pipeline 10 is communicated with a water return and collection vertical pipe 8; the water inlet of the water supply and diversion vertical pipe 7 is communicated with the water outlet of the water pump 6 through the water inlet header pipe 3, and the water inlet of the water pump 6 is connected with the outlet of the heat exchange pipe of the underground heat exchange device 5 through a pipeline; and the inlet of the heat exchange tube of the underground heat exchange device 5 is connected with a backwater collecting vertical tube 8 through a backwater main tube 4. Thus forming a circulation loop. The underground heat exchange device 5 can adopt the existing device, such as the patent: CN 201720758523.1.

In the embodiment, the water pipes 10 are uniformly distributed in the hollow layer 11 to form a heat insulation interlayer, which is beneficial to uniformly and well isolating heat exchange between the wooden outer wall and the outside.

During specific work, water is filled in a water pipeline 10 of the whole system, and the water circulation system is formed by the water pipeline 10, a water supply and water distribution vertical pipe 7, a water inlet header pipe 3, a water pump 6, a backwater and water collecting vertical pipe 8, a backwater header pipe 4 and an underground heat exchange device 5. The power supply of the water pump 6 is started, and the water is circulated by the power of the water pump. After the circulating water enters the underground heat exchange device 5, the heat of the soil layer is absorbed in a certain mode, the temperature of the water rises after the heat is absorbed, the water enters the water through pipeline 10 in each wall body through the water inlet header pipe 3 and the water supply and distribution vertical pipe 7, after the heat is distributed, the temperature of the water is reduced, and the water enters the underground heat exchange device 5 through the return water collecting vertical pipe 8 and the return water header pipe 4, so that a cycle is formed.
