Description

Technical Field

[0001] The utility model relates to the technical field of zero-carbon buildings, in particular to a comprehensive power supply and water circulation system for a zero-carbon building in a hospital. Background Art

[0002] Zero-carbon buildings refer to buildings with zero carbon emissions, which can operate independently of the power grid and rely on solar or wind energy. This type of building does not consume coal, oil, electricity and other energy sources, and its annual energy consumption is all provided by renewable energy generated on site, achieving harmonious coexistence of people, buildings and the natural environment, and minimizing damage to the natural environment. The core principle of zero-carbon buildings: using solar power generation, wind power generation, hydropower generation and other methods as core energy supply methods to achieve "zero energy consumption" in buildings.

[0003] With the popularization of renewable energy and the proposal of low-carbon energy transformation, technologies such as wind power generation, photovoltaic power generation, hydropower generation, and multi-energy conversion are applied to various types of buildings, which can effectively improve energy utilization efficiency, achieve the goal of building energy conservation and emission reduction, and reduce building energy consumption.

[0004] At present, hospital buildings usually generate electricity through solar energy collected by photovoltaic panels installed on the roof, and provide it to the electricity terminals in the building. However, solar power generation alone cannot fully utilize renewable resources, resulting in low energy efficiency of the building. At the same time, the hospital is also a large water user. Only by obtaining a large amount of tap water from the water plant to meet the daily needs of the water terminals will it cause a large waste of resources. In addition, electricity is also required in the process of delivering tap water, which indirectly increases the carbon emissions of the hospital. Utility Model Content

[0055] The water circulation unit includes a water storage tank 8, a water purification pool 9, a water inlet pipe 10, a water outlet pipe 11, a water collecting tank 12 and a water pump 13.

In order to reduce the energy consumption of the system itself, the horizontal height of the water outlet of the water tank 8 is defined as H, and the horizontal height of the water inlet of the water purification pool 9 is defined as h. Then, H>h is satisfied, and the elevations of the filter pool, regulating pool, coagulation pool, sedimentation pool, disinfection pool and the adsorption pool are successively reduced, so that water can spontaneously flow from high to low between the water tank 8 and the water purification pool 9 and within the water purification pool 9.

[0059] Specifically, a plurality of the second photovoltaic panels 15 are laid on the south-facing, southwest-facing and southeast-facing walls of the building.

[0060] In some embodiments, each of the water inlet pipes 10 is provided with a hydroelectric power generation device 16 at the height of the corresponding floor, and the hydroelectric power generation device 16 includes a shell 17, a turbine, a speed increaser 18, a generator 19, and a hydroelectric controller 20. One end of the shell 17 is connected to one end of the water inlet pipe 10 close to the water terminal 14, and the other end is connected to one end of the water inlet pipe 10 close to the water purification pool 9.

[0062] In some embodiments, a rain collecting awning 22 is also included, the center of which is connected to the water storage tank 8, and the periphery of which is connected to the outer fence of the roof of the building.

By setting the rain collecting canopy 22, rainwater can be collected as much as possible on rainy days, further reducing the demand for tap water delivered by the water plant of the building, saving resources, and further reducing carbon emissions. At the same time, by setting the waterproof layer 24 to be made of polyester fiber material, the rain collecting canopy 22 is sun-resistant and the service life is increased. By setting the heat insulation layer 25, it is equivalent to making a layer of heat insulation structure on the roof of the building to prevent the temperature of the top floor of the building from being too high under the sun, resulting in the need to consume more electricity to maintain a comfortable temperature in the building.

[0066] Among them, by arranging the rainwater collecting trough 26 along the outer side of the building, the rainwater flowing downward on the outer side of the building when it rains can be fully utilized, thereby further saving water resources and reducing the carbon emissions of the building. A more preferred solution is to arrange the rainwater collecting trough 26 as close to the ground as possible, and only need to ensure that it is higher than the water collecting tank 12, so as to fully utilize the rainwater on the outer side of the building. At the same time, the rainwater collecting trough 26 can also receive the condensed water of the air-conditioning outdoor unit installed on the outer side of the building, thereby further increasing the water circulation efficiency and saving resources.

[0067] In summary, the embodiment of the present application provides a comprehensive power supply and water circulation system for a zero-carbon hospital building. By setting a photovoltaic power generation unit including a plurality of first photovoltaic panels, a photovoltaic junction box and a photovoltaic controller and a wind power generation unit including a plurality of wind turbines and a wind power controller, the system fully utilizes solar energy and wind energy for power generation, improves energy utilization efficiency, and solves the technical problem in the prior art that the energy utilization efficiency is low because the hospital building only uses photovoltaic panels for solar power generation. At the same time, by setting a water circulation unit including a water storage tank, a water purification tank, a water inlet pipe, a water outlet pipe, a water collection tank and a water pump, the sewage from the water use terminal of the hospital building is recycled and reused. At the same time, the water storage tank can also collect rainwater, which improves the utilization rate of the water resources of the hospital building itself, reduces the amount of tap water required by the hospital from the water plant, reduces the carbon emissions of the hospital building, and solves the problem in the prior art that the hospital building can only use tap water from the water plant. The factory obtains a large amount of tap water to meet the daily needs of the water-using terminals, resulting in a large amount of waste of resources and increased carbon emissions. At the same time, by setting up a second photovoltaic panel, the energy utilization efficiency is improved. By setting up a hydroelectric power generation device 16, while the water is circulating, the gravitational potential energy of the water transported downward from a high place is fully utilized to generate electricity. By combining photovoltaic power generation and wind power generation, the energy utilization efficiency of the system is improved. By setting up a rain collecting awning, the rainwater collection effect is increased. By setting up a waterproof layer of polyester fiber material, a sun-resistant effect is achieved, and the service life of the rain collecting awning is increased. By setting up an insulating layer, the temperature of the top floor of the building is prevented from being too high under the sun, resulting in the need to consume more electricity to maintain a comfortable temperature in the building, thereby increasing carbon emissions. By setting up a rain collecting trough, rainwater and air-conditioning condensate on the outer side of the building are collected to increase water circulation efficiency and save resources.
