AI Technical Summary
Externally mounted air conditioners/heat pumps increase outside air temperature and are inefficient, generating external noise.
Relocating air conditioners/heat pumps inside buildings and using a pressurized water tank to transport brine fluid for cooling/heating, with non-pressurized tanks as backup during water interruptions.
Enhances air conditioner/heat pump efficiency and reduces external noise, while ensuring continuous operation during water supply disruptions.

Abstract
Description
[0001] In countries with high temperatures, air conditioning units mounted on the outside of buildings are most commonly used to cool interior spaces.
[0002] However, the use of externally mounted air conditioners / heat pumps also increases the outside air temperature in cities by approximately 1 to 1.5 degrees.
[0003] My invention attempts to rectify this fact and make air conditioners / heat pumps more efficient by relocating the air conditioners / heat pumps inside the building.
[0004] Most cities have an underground drinking water supply that brings drinking water into the building. If a pressurized water tank (Drawing 1) of various sizes is installed between the supply line and the building's drinking water supply, pipes (copper, aluminum, plastic, etc.) in this tank can absorb the brine (heating / cooling fluid) and transport it to the air conditioning / heat pumps to produce cooling or heating for the building's interior spaces.
[0005] The pressurized water tank can be installed underground or in the basement of the building.
[0006] This allows the air conditioner / heat pump to be operated more efficiently and also eliminates external noise.
[0007] In buildings in cities with temporary interruptions to the drinking water supply, a non-pressurized tank (cistern) will be used underground or in the basement. The pipes for the brine solution can be arranged in a spiral pattern within this tank to transport cooling / heating to the air conditioning / heat pumps. This tank (Drawing 2) can be made of plastic, concrete, steel, etc. A pressurized water pump or similar device can then supply the building with drinking water. Explanation of drawing 1 1. Plastic, copper or steel pipe for brine-liquid spiral 2. Steel pressurized water tank 3. Inflow of brine liquid 4. Return flow of brine solution 5. Threaded connection for inlet or outlet of building water supply 6. Heat pump / air conditioner
[0008] Explanation of drawing 2 1. Threaded connection 1 / 2, 3 / 4, 1, 2 etc. inch 2. Water pipe (plastic, copper or metal) 1 / 2, 3 / 4, 1, 2 etc. inch for water supply 3. Valve for reducing water supply 4. Airtight plastic cavity container as a float for water level regulation 5. Water outlet 6. Nuts for securing the pipe 7. Water tank made of plastic, steel, concrete, or similar materials. 8. Submersible pressurized water pump or similar. 9. Plastic, copper, or steel pipe for brine liquid spiral 10. Return flow of brine fluid 11. Heat pump / air conditioner 12. Inflow of brine liquid 13. Lid for cleaning and servicing
Claims
I hereby apply for patent protection for a pressurized water tank with internal spirally arranged pipes (copper, aluminum, plastic, etc.) for the brine fluid in which the cold / heat of the drinking water is transported to the air conditioning / heat pump. I hereby apply for patent protection for a non-pressurized water tank (concrete, plastic, steel, etc.) that can be installed underground or in the basement and in which cold / heat is transported to the air conditioning / heat pump by means of a brine solution via spirally arranged pipes (copper, aluminum, plastic, etc.).
