Re-reexchange energy-saving building system

Abstract

The invention discloses a re-reexchange energy-saving building system; a building power-supply system thereof adopts a water-supply capillary motor set in a water tank at the top of a building for generating electricity; the electric energy generated by the capillary motor set is used for electric loads of the building; the electric energy generated by solar photovoltaic is used for a water pump to pump the water from an underground tank to the water tank at the top of the building; and the electric energy of valley electricity in mains electricity is used for the water pump to pump the water from the underground tank to the tank at the top of the building. In a building hot water supply system, water storage tanks of a solar energy collector in parallel mode are adopted to supply hot boiling water for the buildings at any time. A building air-conditioning system adopts a ground source heat pump to supply coolness and heat. A water-saving system filters bath water and water for washing faces, clothes and vegetable through an isolating membrane tank to be used as a water source for flushing toilets at the next floor. The invention saves electricity, water, hot water and air-conditioning cost; the fire-fighting pressure water can be directly taken from the top of the building; and rainwater can be naturally injected in the tank at the top of the building for the system to use. The cost of construction of the building of the invention is 30-50% higher than that of a common building, and the cost on electricity, water and air-conditions can be saved for the construction cost on the building function configuration within only 3-5 years.

Description

Technical field: [0001] The invention relates to the technical field of buildings, more specifically to the power supply, hot water supply, air conditioning, water-saving system and fire-fighting system of buildings. Background technique: [0002] The current power supply system of the building is generally provided by the city electricity, and its disadvantage is that the power supply cost is relatively high. [0003] The hot water supply system of the building generally uses solar water heaters to supply low-temperature hot water, and the boiling water is heated by electric power to generate hot water by each sub-user. Its shortcoming is: the boiled water of temperature above 90 ℃ needs each sub-user to burn by oneself, and one is wasting electric power, and the other is to increase the cost of using boiled water. [0004] The flush toilets in the buildings are all flushed with tap water, wasting water resources. [0005] The air conditioner in the building adopts electr...

AI Technical Summary

Problems solved by technology

[0002] The current power supply system of the building is generally provided by the city electricity, and its disadvantage is that the power supply cost is relatively high

Its disadvantages are: boiled water with a temperature above 90°C needs to be fired by each user, which is a waste of electricity and increases the cost of boiling water

[0004] The flush toilets in the building are all flushed with tap water, wasting water resources

[0005] The air conditioner in the building adopts electric heating and cooling, and there is no external auxiliary energy, which is not energy-saving enough.

[0006] The fire protection system of the building needs to maintain the pressure of the fire water tank on the roof frequently. At the same time, the fire pump also needs to be started frequently, which is very cumbersome to start the fire pump frequently.
